AN INTERVIEW WITH RCA ARMSTRONG MEDALIST – DR. THOMAS MARZETTA

By Dr. Nathan “Chip” Cohen, Ph.D. Dr. Thomas Marzetta will receive the Radio Club of America’s 2019 Armstrong Medal at RCA’s November 23, 2019, banquet and awards ceremony. The Armstrong Medal reflects the recipient’s legacy of innovation and his many contributions to the art and science of radio. I had the opportunity of interviewing Dr. Marzetta in early October 2019.

THE ARMSTRONG MEDALIST In 1935, the Radio Club of America (RCA) established a tradition of publicly recognizing outstanding achievements in the arts and sciences of radio and wireless communications. RCA presented its first award to Major Edward H. Armstrong for his invention of circuits that make AM and FM radio possible, and for Major Armstrong’s lifetime of championing work that established the foundation for modern radio technology.

RCA presents the award, now known as the Armstrong Medal, when an individual has demonstrated excellence and made lasting contributions to radio arts and sciences.

Dr. Thomas Marzetta, the 2019 Armstrong Medalist, is the distinguished industry professor at the New York University (NYU) Tandon School of Engineering's Electrical and Computer Engineering Department, and is director of NYU Wireless. Dr. Marzetta is the creator of “massive MIMO” (Multiple-Input Multiple-Output), which is a key enabler of the fifth generation of wireless technology, or 5G. Dr. Marzetta was the primary scientist involved with optimizing this spectral efficiency in wireless. He holds 47 U.S. patents on MIMO and wireless power transmission.

• Prior to NYU, Dr. Marzetta performed research in: petroleum exploration (Schlumberger-Doll Research, 1978 – 1987), defense (Nichols Research Corporation, 1987 – 1995), and telecommunications (Bell Labs, 1995 – 2017). At Bell Labs, he directed the Communications and Statistical Sciences Department within the former Mathematical Sciences Research Center, and he was elected a Bell Labs Fellow.

• He is lead author of the book Fundamentals of Massive MIMO and has published numerous papers and conference presentations.

• He was on the advisory board of MAMMOET (Massive MIMO for Efficient Transmission), a European Union (EU)-sponsored FP7 project, and he was coordinator of the GreenTouch Consortium’s Large Scale Antenna Systems Project.

Thomas Marzetta, 2019 RCA Armstrong Medal recipient. (NYU Wireless)

In September 2019, Dr. Marzetta succeeded Dr. Theodore (Ted) Rappaport (RCA Fellow and 2018 Armstrong Medalist) as director of NYU Wireless.

Dr. Marzetta has received important recognitions for his contributions to Massive MIMO, including the 2017 IEEE Communications Society Industrial Innovation Award, the 2015 IEEE Stephen O. Rice Prize, and the 2015 IEEE W. R. G. Baker Award. He was elected a Fellow of the IEEE in 2003, and he received an honorary doctorate from Linköping University in 2015.

MASSIVE MIMO Massive MIMO employs numerous small, individually controlled, low-power antennas to direct streams of information, selectively and simultaneously, to many users. This improves spectral efficiency to levels significantly greater than 4G service. It also provides high-quality service throughout the cell, while improving simplicity, scalability, and energy efficiency.

Gains in speed, system throughput, and capacity have been obtained, permitting mobile traffic expansion of nearly 20 times. Further expansion is anticipated, with outlooks that by 2021 video will account for more than 78 percent of all mobile data, and smart terminals will consume an average of 15 gigabytes (GB) of data per month. www.radioclubofamerica.org | FALL 2019 PROCEEDINGS

THE INTERVIEW Chip: Congratulations on your many successes and your well-deserved recognition from RCA. What first attracted you to radio?

Dr. Marzetta: Thank you, Chip. To receive the Armstrong Medal is a great honor. My father, Louis Marzetta, was an electrical engineer at National Bureau of Standards (later renamed NIST), and a radio amateur (W3LNR; earlier, W1LJF). When I was a boy, my father and I built a crystal radio, and he taught me Morse code. I was 13 when I got my Novice license (WN3BQK, 5 words/minute code). A year later I passed the General exam (13 words/ minute) and became WA3BQK. Chip: Do you think radio is still recognized, or is it underappreciated today; have the concepts of cellular technology completely replaced radio?

Dr. Marzetta: Good questions! One of the triumphs of wireless communications is that it is ubiquitous, and the details of the technology are largely invisible to the enduser. This is different than the days of analog television when you switched to another station, and had to readjust a rabbit-ear antenna for good reception, or when you tuned a radio by adjusting a variable capacitor!

Digital wireless, as exemplified by cellular technology, has huge advantages over analog radio, including incredible flexibility, spectral efficiency, and economy. That said, I don’t think that AM and FM are going away. If FM broadcast stations converted to digital audio, their coverage would be reduced drastically: for the same 200 kilohertz (kHz) spectrum, high-fidelity digital audio would require a minimum signal-to-noise (SNR) ratio of 21 decibels (dB), whereas wide-band FM (Armstrong’s greatest invention!) gives good reception at 10 dB or less. For firefighter’s voice

communication, analog linear modulation (AM or SSB) is superior to digital technology, because the quality of the received signal degrades gracefully as SNR decreases, whereas digital communication is lost totally when SNR falls below a threshold.

Chip: You spent many years at Bell Labs. What first attracted you to Bell Labs, and what do you think were its greatest attributes that fostered its legacy of innovation?

Dr. Marzetta: I came to Bell Labs by an indirect route.

When I finished graduate school in 1978, I already had a job offer from Bell Labs, which I turned down, in favor of the oil field services company, Schlumberger.

The petroleum industry was booming at that time, Schlumberger was converting its Ridgefield, Connecticut lab into a fundamental research lab. In the process, it hired more than 100 Ph.Ds: engineers, physicists, computer scientists, and mathematicians. This was an exciting opportunity that I could not resist.

In 1995, I had a second chance to join Bell Labs. My wife, Ingrid Carlbom, was recruited to head a department at Bell Labs, and I was offered a one-year-term position.

This eventually extended to 22 years. At that time, I had never worked in communication theory. On my very first day of work, Jerry Foschini, one of the pioneers of MIMO, told me about his recent discoveries. I spent the next 10 years working on improvements to MIMO. This research led me to originate the concept of Massive MIMO. Bell Labs was (and still is, under its current Nokia ownership) an incredible place to work. You were surrounded by world-class experts in every field that might be relevant to your research. While short-term results were certainly appreciated, long-term research

FALL 2019 PROCEEDINGS | www.radioclubofamerica.org

was encouraged. Above all, the individual researcher was given unusual freedom to choose research directions. I was extremely fortunate to have both great collaborators and managers who were willing to support risky research.

Chip: You have multiple patents and fathered a new era in cellular communication. What is the project or invention of which you are most proud?

Dr. Marzetta: Some of my earlier projects were tremendously interesting to me: the theoretical and experimental development of hydrophone arrays for vertical seismic profiling, a mathematical investigation of cavitation induced by an imploding seismic source in a borehole, and velocity-sensitive filters for video motion detection.

My greatest success has been Massive MIMO. While a researcher or inventor takes satisfaction from a clever idea or a fortuitous discovery, there is nothing more gratifying than to see your work have a major impact on industry and society.

Chip: Today’s communications and research technology environments have vastly changed. What significant improvements have benefitted the rate of innovation, and have any harmed or hurt the rate of innovation?

Dr. Marzetta: With a few exceptions, industrial research tends to be have short-term horizon. A scarcity of fundamental research is hurting the rate of innovation.

Chip: What new breakthroughs do you foresee ahead, both in your field, and more generally?

Dr. Marzetta: If you don’t mind, I’ll confine my answer to the field of wireless! Now is the time to address the question: what next? What more can we do at the physical layer level after Massive MIMO and millimeter wave (mmWave) are fully exploited? Some people expect major discoveries to be made through artificial intelligence (AI). Others look to ever-higher carrier frequencies (e.g., terahertz wireless). My own current research, which I call “Beyond Massive MIMO,” is based on a closer fusion of electromagnetic theory and communication theory.

I expect also that entirely new applications of wireless will emerge.

Chip: Are there any particular challenges ahead, both technically, and more generally?

Dr. Marzetta: The challenge of working in the field of wireless is that however clever wireless engineers are, people will always demand higher throughput, greater reliability, and reduced latency. The field is fundamentally different from optical communications: you can always lay down more optical fiber, but you can never lay down more spectrum!

Chip: What opportunities do you see in the future for communications technology, and for those interested in this field?

Dr. Marzetta: To quote Massimo Franceschetti in his recent book Wave Theory of Information, “Engineers are far from reaching the limits that nature imposes on communication: our students have a bright future in front of them!”

The Top Programming Languages for 2019

I

EEE Spectrum announced its sixth-annual interactive ranking of the top programming languages. This year IEEE undertook a major overhaul, changing some of the underlying metrics and building a new streamlined interface.

But the basic idea and methodology remains the same: combining data from multiple sources to rank the popularity of the programming languages that are used for the type of coding in which you are interested. The default weighting is optimized for the typical IEEE Spectrum reader. Top 10 languages of 2019 are shown to the right.

Python’s popularity is driven in no small part by the vast number of specialized libraries available for it, particularly in the domain of artificial intelligence, while the Keras library is a heavyweight among deep-learning developers— Keras provides an interface to the TensorFlow, CNTK, and Theano deep-learning frameworks and tool kits. Deep learning is not the only field where Python is having an impact that could not have been anticipated when the language was released in 1991. The dramatic increase in computing power found in microcontrollers means that embedded versions of Python, such as CircuitPython and MicroPython, are becoming increasingly popular among makers.

NeuroEM Therapeutics Announced Alzheimer’s Memory Loss Reversed by Easy-to-Wear Radio Head Device

T

he ARRL Letter dated August 8, 2019, noted a press release regarding ARRL member Eric Knight, KB1EHE, who played a role in the development of a radio frequency (RF)-based Alzheimer’s Disease (AD) treatment that now shows great promise. A study published in the Journal of Alzheimer’s Disease following a months-long U.S. Food and Drug Administration (FDA) clinical trial of the treatment protocol concluded that memory decline in most patients “appeared to have been reversed to cognitive levels equivalent to 12 months earlier” after two months of treatment.1 The clinical trial concluded in December 31, 2018, and focused on the initial efficacy of what NeuroEM Therapeutics, Inc.—the company developing the device— calls “transcranial electromagnetic treatment” (TEMT), using a noninvasive head-worn device called the MemorEM™. Findings point to a potential breakthrough in AD treatment, with a larger pivotal study being planned to confirm these findings.1 The following article shares the contents of the press release.

Phoenix, AZ (August 6, 2019) – NeuroEM Therapeutics, a clinical stage medical device company focused on neurodegenerative diseases, today announced findings from an early stage study, which assessed safety and initial efficacy of transcranial electromagnetic treatment (TEMT) with the company’s investigational MemorEM™ head device for Alzheimer’s disease (AD). Results from the two-month trial demonstrate that TEMT was safe in all eight participating patients with mild to moderate AD and enhanced cognitive performance in seven of them, as measured by standard cognition scales . The study was published in the Journal of Alzheimer’s Disease.

“This pioneering study suggests that TEMT may be an entirely new therapeutic intervention against Alzheimer’s disease,” said Dr. Gary Arendash, CEO of NeuroEM Therapeutics. “Our bioengineering technology may be succeeding where drug therapy against this devastating disease has thus far failed. TEMT appears to be affecting the Alzheimer’s disease process through several actions directly inside neurons (brain cells), which is where we believe the disease process needs to be stopped and hopefully reversed."

The inability of pharmaceuticals thus far to effectively slow or reverse cognitive impairment of AD has led to the development of non-pharmaceutic neuromodulary approaches, including TEMT, the newest such approach.

TEMT is different from other neuromodulary technologies, such as transcranial magnetic stimulation or transcranial direct current stimulation, since it uses both magnetic and electric waves. The study is the first to administer

electromagnetic waves to the entire human brain over an extended period of two months.

“Despite significant efforts for nearly 20 years, stopping or reversing severe memory impairment in people with Alzheimer’s disease has eluded researchers thus far,” said co-author Seven countries have signed a convenAmanda Smith, M.D., tion to create the Square Kilometre Director of Clinical Array Observatory. (Courtesy: SKA) Research, University of South Florida Health, Byrd Alzheimer’s Institute, the clinical center for the study. “These results provide preliminary evidence that the neuromodulary approach we assessed in this very small study may have the capacity to enhance cognitive performance in patients with mild to moderate disease."

KEY FINDINGS1 After two months of treatment administered at home by a caregiver, none of the eight patients in the study exhibited any recurrent changes in eating or drinking, daily movement activities or anxiety level/mood, as recorded by caregivers in daily diaries. No patient complained of headaches, brain sensations or any other TEMT side effects during or following treatment. Assessments conducted at the clinic throughout the study found no treatment-related adverse events (AEs) and no suicide tendencies. Additionally, post-treatment brain scans revealed no visible induction of tumors or brain bleedings called micro hemorrhages.

An initial efficacy analysis showed that the seven patients who responded to TEMT had a clinically important combined increase in cognitive performance at the end of the two-month treatment period, as measured with the Alzheimer’s Disease Assessment Scale-Cognitive Subscale (ADAS-cog) and effect size (ES).5 ES=1.21; p<0.02.

This corresponded to an average 4.1 point improvement on the ADAS-cog, a widely used AD clinical assessment tool. Improved cognition generally was maintained at two weeks after treatment completion, consistent with an effect on the disease process itself: ES=1.01; p<0.05; ADAS-cog improvement of 4.3 points. By comparison, a typical decline in ADAS-cog in people with AD without intervention is expected to be around 4 points over a 12-month period.2 All eight patients improved in a www.radioclubofamerica.org | FALL 2019 PROCEEDINGS

second established task, the Rey AVLT, wherein clinically important increases in word recall were present at the end of the two-month treatment period (ES=1.55; p<0.005) and two weeks following treatment completion (ES=1.55; p<0.005).

Additional results from the study find: • TEMT also showed effects on Alzheimer’s markers in blood and the cerebrospinal fluid (CSF) around the brain that were consistent with it having “diseasemodifying” effects.

• TEMT appears to provide a combination of mechanisms to attack the AD process, including disaggregation of two toxic proteins (beta-amyloid and tau) that appear to be the disease’s root causes— something the study’s authors believe has not been seen with other AD therapeutics that are in clinical development.

• In individual patients, magnetic resonance imaging (MRI) brain scans also revealed signs of increased neuronal connectivity in the cingulate cortex/cingulum, an area of the brain that is involved in AD and important for integrating cognitive processes.

ABOUT THE STUDY1

Eric Knight, KB1EHE.

The pilot study was a singlecenter, single-arm trial in eight patients 63 years of age and older with mild to moderate AD to evaluate the safety and initial efficacy of TEMT. Patients were enrolled at the University of South Florida Health/Byrd Alzheimer’s Institute, which also conducted all clinical study assessments.

Treatment was administered in the patient’s home by a caregiver, using the MemorEM. This investigational, novel noninvasive treatment cap delivers radio waves to the brain and is designed to be easy to wear. Patients received TEMT for one-hour periods twice daily for two months for a total of 120 treatment sessions. Caregivers also monitored certain patient vital signs and behaviors, such as blood pressure, body temperature, eating, drinking, movement activities and anxiety level/mood, and recorded findings in a daily diary. In addition, adverse events and suicide tendencies were assessed during clinical visits throughout the duration of the trial. Final clinical assessments were conducted two weeks after study completion. Based on the findings and the positive feedback from patients, all eight were offered continued TEMT in a four-month extension study. Seven patients agreed to participate in the extension.

ABOUT ALZHEIMER’S DISEASE4 Alzheimer’s disease (AD) is a progressive and ultimately lethal brain disease leading to memory loss, language problems and other serious symptoms. AD is caused by the damage or destruction of brain cells (neurons) in parts of the brain that control thinking, learning and memory.

Over time, people with AD increasingly become limited in performing daily activities and eventually become bedbound, requiring care around the clock.

AD is the sixth leading cause of death in the U.S. An estimated 5.8 million Americans are living with the disease. By 2050, this number is projected to more than double to 14 million. In 2019, AD and other dementias will cost the country $290 billion. By 2050, these costs could rise to $1.1 trillion.

ARRL Awards Technical Innovation Award to RCA Member Joe Taylor and Steve Franke

T

he 2019 Technical Innovation Award issued by the Amateur Radio Relay League (ARRL) has been granted to the FT8 development team, led by Joe Taylor, K1JT, and Steve Franke, K9AN. The ARRL board of directors recognized the success of the FT8 digital mode and said that FT8 has “proven effective for all amateurs” and has “proved to be effective” in times of poor propagation, revolutionizing many aspects of ham radio.

FT8 The FT8 digital mode has been luring many of those already using the popular JT65 “weak-signal” mode.

FT8 offers a shorter transmit-receive cycle, meaning quicker contacts and sensitivity down to –20 decibels (dB) on the AWGN channel. Contacts are four times faster than with JT65 or JT9, and an entire FT8 contact can take place in about 1 minute.

The new mode is named after its developers, Steven Franke, K9AN, and Joe Taylor, K1JT, the “F” and “T” in “FT8.” The numeral designates the mode’s 8-frequency shiftkeying format. Tones are spaced at 6.25 hertz (Hz), and an FT8 signal occupies just 50 Hz. Unlike JT65 or JT9, transmit and receive cycles in FT8 each last about 15 seconds. Like JT65, FT8 requires accurate time synchronization. An auto-sequencing feature offers the option to respond automatically to the first decoded reply to a CQ. Dr. Taylor’s original release notes asserted, “FT8 is an excellent mode for HF DXing and for situations like multi-hop Es on 6 meters, where

for their discovery in 1975 of the first binary pulsar system. Their discovery confirmed Albert Einstein's theories about the existence of gravitational waves. Dr. Taylor regaled the audience with tales about the discovery and played recordings of binary pulsar signals. Dr. Taylor received RCA’s Lifetime Achievement Award at that event. He has remained an active RCA member.

Dr. Taylor stated, “SSB and CW are general-purpose modes.”

“They are good for ragchewing, DXing, contesting, emergency communications, or whatever. FT8 and the other modes in WSJT-X are special-purpose modes. They are designed for making reliable, errorfree contacts using very weak signals — in particular, signals that may be too weak for the more traditional modes to be usable, or even too weak to hear.”

etails are still being fleshed out, but AMSAT and ARISS are working on the design of an amateur radio system for the National Aeronautics and Space Administration (NASA) Lunar Gateway. As NASA explains, the Gateway “will be a small spaceship in orbit around the moon that will provide access to more of the lunar surface than ever before with living quarters for astronauts, a lab for science and research, ports for visiting spacecraft, and more.”

For NASA, the Lunar Gateway is “a spaceport for human and robotic exploration to the moon and beyond.”

For radio amateurs, the Lunar Gateway will represent the next step in moving ham radio away from lowEarth orbit and into deep space.

Under the current timeline, initial sections of the Gateway are scheduled to launch in 2022, with the Gateway in lunar orbit by 2026.

“To make this happen, we are leveraging the work and expertise of

AMSAT and ARISS Designing Amateur Radio System for Lunar Gateway

the worldwide AMSAT organizations and the international ARISS community,” ARISS-International Chair and AMSAT Vice President for Human Spaceflight Programs Frank Bauer, KA3HDO, said. “We have an international team working on this and are meeting twice a month to mature the concept.” The ARISS concept was presented to NASA in May and got positive feedback, and was favorably received a few weeks later at the ARISS-International meeting in Montreal from the Canadian Space Agency’s gateway program manager.

“The Amateur Radio Exploration (AREx) team has done some really good work,” Bauer continued. “The challenge for amateurs will be on the order of a 30 dB signal path loss as compared to LEO.” The Lunar Gateway will serve as a solar-powered communications hub, science lab, short-term habitation module, and a holding area for rovers and other robots that may be bound

for the moon or for other planets.

NASA is leading the project in collaboration with commercial and international partners, including all of the International Space Station partners.

“We need to develop a block diagram of a system and subsystems and find team members who want to work on each,” Bauer said when the ARISS-International team met in Montreal. “We must set up requirements and interface documentation. We need to solidify the frequencies to use, working with the International Space Frequency Coordination Group.”

ARISS ARRL Representative Rosalie White, K1STO, said that ARISS is working to spread the word about the new initiative. She also hopes the new project may inspire the generosity of the amateur radio community.

ast fall, scientists replicated the famous Thomas Edison demonstration of “Mary Had a Little Lamb” on his new phonograph.

Only this time, atoms were at play. The following article from PhysicsWorld explains.

The sound of a human voice singing “Mary Had a Little Lamb” has been played by a radio receiver that exploits the quantum properties of a cloud of atoms—140 years after the nursery rhyme was famously recorded by Thomas Edison. In Edison’s case, sound was recorded by using a stylus to rearrange the positions of vast numbers of aluminum atoms on a foil-wrapped cylinder. Now, David Anderson, Rachel Sapiro and Georg Raithel at Rydberg Technologies in Ann Arbor, Michigan, have used a cloud of highly excited cesium atoms to store and playback AM and FM radio signals.

The concepts behind their feat promise to address some of the underlying challenges of creating radio communication systems that offer information security and resilience against electromagnetic interference. In principle, quantum radios based on clouds of atoms could be immune to intense interfering fields while transmitting clear signals that cannot be tampered with.

Radio Uses Rydberg Atoms to Play ‘Mary Had a Little Lamb’

The receiver built by Anderson and colleagues uses Rydberg atoms. Such atoms are in highly excited quantum states in which some electrons spend most of their time relatively far away from the atomic nucleus. As a result, Rydberg atoms can function as tiny antennas that are extremely responsive to electromagnetic fields.

INFORMATION STORAGE Indeed, the resonant frequencies of Rydberg atoms match the radio and microwave frequencies commonly used in communications.

The atoms are strongly coupled to these fields, making them ideal for storing information encoded in radio-frequency (RF) and microwave signals. Furthermore, this stored information can be converted back to RF and microwave signals using spectroscopic techniques In their experiment, the Ann Arborbased physicists replaced the antenna of a radio receiver with a cloud of cesium Rydberg atoms contained in a centimeter-sized glass cell. Their goal was to demonstrate how the system could receive, record and play back signals in the audio range.

microwaves. The sound frequencies encoded in the signals spanned over four octaves—representing most of the frequency range of the human voice.

Operating the system involved making real-time, quantum-optical measurements of how the Rydberg atoms respond to the AM and FM signals. This meant that there was no need for any electronics to demodulate the signals. With virtually no circuitry required, the team’s setup was remarkably compact, which they say makes it highly resistant to interfering electromagnetic fields.

While the dynamic range of the receiver falls slightly short of the standards of modern devices, the trio plan to address in this shortcoming in future experiments.

The research is described in an August 26, 2018 article published on arXiv.

ormer ARRL CEO and Radio Club of America (RCA) member David Sumner, K1ZZ, has contributed to the April 2019 issue of ITU News Magazine, published by the International Telecommunication Union. The issue is devoted to “terrestrial wireless communications,” which includes the Amateur Radio and Amateur Satellite services.

Sumner’s article, “Self-Training, Intercommunication and Technical Investigations: the Amateur Service in the 21st Century,” discusses amateur radio within the context of a global network of experimenters and communicators who, in Sumner’s words, “expand the body of human knowledge and technical skills that are essential to development and offer a resource that can literally save lives when natural disasters disrupt normal communications channels.”

“Amateur licensees are grateful that ITU member-states continue to recognize the benefits of providing direct access to the radio spectrum to qualified individuals,” said Sumner, who now serves as secretary of the

Global Institutions Support Amateur Radio Communication and Experimentation

International Amateur Radio Union (IARU), an ITU sector member.

Sumner points out that access to frequency bands “spaced throughout the radio spectrum” is critical to amateur radio’s future. He notes that the initial pattern of ham allocations dates back to 1927 and the International Radiotelegraph Conference. Allocations have been expanded at subsequent conferences, most recently at World Radiocommunication Conference 2015 (WRC-15), when ham radio obtained a tiny secondary band near 5.3 megahertz (MHz). (An earlier WRC was responsible for the amateur service’s lowest-frequency allocations, 135.7 - 137.8 kilohertz [kHz] and 472 - 479 kHz.) The 1979 World Administrative Radio Conference (WARC) extended terrestrial allocations above 40 gigahertz (GHz) to include amateur allocations.

“If a future World Radiocommunication Conference extends allocations above 275 GHz, adequate provisions for amateur experimentation should be made,” Sumner observed.

The first item on the agenda for WRC-19, which takes place this fall in Egypt, calls on delegates to consider an allocation at 50 MHz to the amateur service in ITU Region 1 (Europe, Africa, and the Middle East) that aligns with existing allocations in Regions 2 and 3.

Sumner notes that ITU “plays an essential role” in keeping the spectrum clear of unwanted interference and emissions, an effort he said is “especially vital to the amateur service, which uses sensitive receivers to compensate for practical and regulatory limitations on antennas and transmitter power levels.”

IARU Secretary David Sumner, K1ZZ.

Sumner also pointed to the role radio amateurs can play in developing and refining communication protocols, including digital techniques, to improve weak-signal performance. He noted that Joseph Taylor, K1JT—a co-developer of such digital modes as FT8, FT4, and JT65—received an ITU Gold Medal in recognition of his outstanding contributions to radio communications.

As Sumner explained, the IARU—a federation of more than 140 member societies—represents the interests of radio amateurs around the world before ITU. IARU’s contribution to the work of ITU began in 1932 with its admission to participate in the work of the International Radiocommmunication Consultative Committee (CCIR). IARU is a member of the ITU radiocommunication and development sectors.

“The IARU is proud to be an active member of the ITU community,” Sumner said.

ood fortune and cutting-edge scientific equipment have allowed scientists to observe a gamma-ray burst jet with a radio telescope and detect the polarization of radio waves within it for the first time—moving us closer to an understanding of what causes the universe’s most powerful explosions.

Gamma-ray bursts (GRBs) are the most energetic explosions in the universe, beaming out mighty jets that travel through space at greater than 99.9 percent of the speed of light, as a star much more massive than our sun collapses at the end of its life to produce a black hole.

Studying the light from GRBt jets as we detect them travelling across space is our best hope of understanding how these powerful jets are formed, but scientists need to be quick to

New Astronomers VoluntaryMake Television First Detection StandardsofTake Polarized Hold Radio Waves in Gamma-Ray Burst Jets

get their telescopes into position and get the best data. The detection of polarized radio waves from a GRB jet, made possible by a new generation of advanced radio telescopes, offers new clues to this mystery.

The light from this particular event, known as GRB 190114C, which exploded with the force of millions of suns’ worth of trinitrotoluene (TNT) about 4.5 billion years ago, reached NASA’s Neil Gehrels Swift Observatory.

A rapid alert from the observatory allowed the research team to direct the Atacama Large Millimeter/Submillimeter Array (ALMA) telescope in Chile to observe the burst just two hours after it was discovered.

Two hours later the team was able to observe the GRB from the Karl G. Jansky Very Large Array (VLA)

telescope when it became visible in New Mexico, USA. Combining the measurements from these observatories allowed the research team to determine the structure of magnetic fields within the jet itself, which affects how the radio light is polarized. Theories predict different arrangements of magnetic fields within the jet depending on the fields’ origins, so capturing radio data enabled the researchers to test these theories with observations from telescopes for the first time.

The research team, from the University of Bath, Northwestern University, the Open University of Israel, Harvard University, California State University in Sacramento, the Max Planck Institute in Garching, Germany, and Liverpool’s John Moores University discovered that only 0.8

percent of the jet light was polarized, meaning that the jet’s magnetic field was ordered over relatively small patches—each less than about 1 percent of the diameter of the jet.

Larger patches would have produced more polarized light.

These measurements suggest that magnetic fields may play a less significant structural role in GRB jets than previously thought.

This helps us narrow the possible explanations for what causes and powers these extraordinary explosions. The study is published in Astrophysical Journal Letters.

First author Dr Tanmoy Laskar, from the University of Bath’s Astrophysics group, said: “We want to understand why some stars produce these extraordinary jets when they die, and the mechanism by which these jets are fueled – the fastest known outflows in the universe, moving at speeds close to that of light and shining with the incredible luminosity of over a billion suns combined.

“I was in a cab on my way to O’Hare airport in Chicago, following a visit with collaborators when the burst

went off. The extreme brightness of this event and the fact that it was visible in Chile right away made it a prime target for our study, and so I immediately contacted ALMA to say we were going to observe this one, in the hope of detecting the first radio polarization signal.

“It was fortuitous that the target was well placed in the sky for observations with both ALMA in Chile and the VLA in New Mexico. Both facilities responded quickly and the weather was excellent. We then spent two months in a painstaking process to make sure our measurement was genuine and free from instrumental effects. Everything checked out, and that was exciting.”

Dr Kate Alexander, who led the VLA observations, said, “The lower frequency data from the VLA helped confirm that we were seeing the light from the jet itself, rather than from the interaction of the jet with its environment.”

Dr Laskar added: “This measurement opens a new window into GRB science and the studies of energetic astrophysical jets. We would like to

understand whether the low level of polarization measured in this event is characteristic of all GRBs, and if so, what this could tell us about the magnetic structures in GRB jets and the role of magnetic fields in powering jets throughout the universe.”

Professor Carole Mundell, Head of Astrophysics at the University of Bath, added: “The exquisite sensitivity of ALMA and rapid response of the telescopes has, for the first time, allowed us to swiftly and accurately measure the degree of polarization of microwaves from a GRB afterglow just two hours after the blast and probe the magnetic fields that are thought to drive these powerful, ultrafast outflows.”

The research team plans to hunt for more GRBs to continue to unravel the mysteries of the biggest explosions in the universe.

AMERICA STARTS ITS SPACE PROGRAM – EXPLORER 1

By Dr. Henry Richter America’s space program started about 60 years ago with the launch of its first satellite Explorer 1 on January 31, 1958. The satellite program came about as a result of a major international scientific effort called the International Geophysical Year (IGY). The IGY came about as a result of a meeting of geophysical and upper atmosphere scientists held at the home of Dr. James A. Van Allen in Iowa City, Iowa in the early 1950s.

The group broadly considered a wide range of various collaborative research projects. They went back to two major international efforts, each called the international polar year. The first was held from 1882 to1883 and the second held from 1932 to 1933. They felt it was time for another such project, this time thinking even beyond just the earth’s polar region. They proposed a worldwide effort which they dubbed “the International Geophysical Year” (IGY) and proposed getting a number of scientists from large number of countries involved to thoroughly study our earth. They knew that a major peak in the solar activity cycle was coming in a few years, so this seemed like a good time for a major effort. The solar peak would occur in 1957, and they proposed January 1957 through July 1958 for the research.

A number of countries were brought into this proposed research effort, ultimately ending at about 67. The United States of course took one of the lead roles in planning and execution of projects for the IGY. Programs were proposed to study the interior of the earth, the mantle, the surface and subsurface, the atmosphere, the upper atmosphere, and near space. It was a very ambitious effort to say the least.

possible participants. The only organizations in the U.S. that had existing rocket programs were the armed services. So, offerings and proposals were obtained from the Air Force, the Army, and the Navy. These proposals were submitted around the middle of 1955. The Army’s proposal was put together by the Army Ballistic Missile Agency (ABMA), headed by Dr. Wernher von Braun and General Bruce Maderis, and by the Jet Propulsion Laboratory (JPL), headed by Dr. William Pickering. The Navy proposal was submitted by the Naval Research Laboratory (NRL).

The proposals were reviewed by a committee called the Stewart Committee, which was set up by the Department of Defense. After a set of presentations and reviews, the committee recommended the proposal submitted by the Navy. This was very disappointing to those of us involved in the Army proposal since the Army had a great deal of experience in developing rockets for tactical purposes.

The Navy proposed creating and using all new rockets that were yet to be developed and tested. Some of us felt that perhaps this was somewhat due to the influence of President Eisenhower who wanted the new space program to be totally a civilian operation with no military involvement.

For a number of years, upper atmosphere researchers have used a combination of high-altitude balloons and sounding rockets to make measurements. At best, the rockets only went up a few hundred kilometers and fell back to the earth after making a few measurements.

Sometimes, the measurements were telemetered back, and sometimes, data was obtained by recovering recorders or films from the rockets. In the time period of the IGY, it appeared technically possible to launch a rocket with a payload that would not return, namely, an earth-orbiting satellite. So, satellite measurements were incorporated into the planning for the IGY. Two nations announced that they would attempt to develop and launch earth satellites during the period of the IGY: the Soviet Union and the United States. This is where the so-called space race was born.

The United States did what it typically does when starting a new program: it asked for proposals from

The Navy satellite program, named “Vanguard”, was soon funded and off and running. The Army team was forbidden to do any satellite development or preparation work. However, we did not always follow instructions.

The Army’s proposal envisioned using a four stage rocket, based on the ABMA Redstone rocket as the first stage together with three JPL developed highspeed upper stage rocket assemblies. This all involved hardware with which we were very familiar and already had considerable success.

Our unauthorized satellite program consisted of several areas. There were three elements to launching our satellite. First, we needed a rocket system to reach orbit at the proper speed. Second, the satellite itself needed contents and communications. Third, we needed a radio tracking and receiving system to make contact with the satellite.

Both ABMA and JPL personnel worked on the rocket system. ABMA completed their Redstone rocket, which was now available for tactical use. Their follow-on program was the Jupiter intermediate range ballistic missile, which was capable of 1500 miles range. At the same time, JPL was in the final stages of completing the Sergeant solid propellant rocket. A number of small-scale (6-inch diameter) test rockets were used to

investigate different solid propellant formulations and effectiveness. The scale rockets were proposed to form the high-speed stages for the satellite launch vehicle.

As part of the Jupiter development program, a reentry test body was required to successfully carry a nuclear warhead out of and back into the atmosphere. For the rocket to reach 1500 miles, any trajectory required the rocket to leave the atmosphere and to reenter at the end of its journey. There would be significant friction heating as the body reentered the earth’s atmosphere at high speed. Verification of the design proposed for the reentry body was critical, but the survivability could not be ascertained by engineering measurements; an actual test was required.

Therefore, since an actual Jupiter rocket was not yet available for test, a vehicle was required to carry a test reentry nose cone on the expected trajectory of 1500 miles. The vehicle developed for this was a Redstone rocket with some high-speed rocket stages on top. The high-speed stages could be based on the JPL small-scale, Sergeant test rockets. This was just the configuration that would be used for a satellite launch vehicle. Imagine that! So, work was immediately started to develop and schedule a reentry vehicle test configuration, called the “RTV” program. The first flight test was scheduled within a year. Working groups were organized, and preparations commenced.

Within JPL, the propulsion people started working, and my electronics people began on the satellite. The analysis group began on trajectory and orbit determinations.

The launch vehicle had full guidance capability, so it could control the ascent trajectory and attitude. The high speed stages did not have the capacity for guidance equipment or a steering mechanism, so it was decided to spin stabilize their pointing direction. The Redstone would get the vehicle to its maximum altitude and then point the high speed stages in the proper direction.

The spinning, with its gyroscopic action, would keep the additional rockets pointed properly during the rocket burnings. There were three high speed rocket assemblies, all contained in a so-called tub. The second stage had eleven rockets in a circle. The third stage consisted of three rockets inside the second stage. The fourth stage used a single rocket (with a half rocket and half satellite payload) mounted on the front of the third stage.

The propulsion group ran a number of tests on scale versions of the Sergeant rockets, spinning them in a tub in the test pit to make sure the centrifugal force did not have any deleterious effects.

They also ran various propellant formulations to pick the best mixture to give the needed thrust. This was done in concert with the trajectory calculating group.

The other part of the design and development process was the satellite payload and communications system.

We had been given the shape factor, size, and allowable weight of the satellite portion of the fourth stage container, so just needed to decide what would go in and start specifications and design. Obviously, some sort of radio transmitter would be required to get position and data from the satellite. Some sort of scientific data collection instrument would also be required, but we could not foresee what this would be since those experiments were under the control of the IGY committees. We would have to independently develop instrument space and a telemetry system to send whatever data was gathered to radio tracking stations.

Work began on the satellite. The largest uncertainty and essential survival threshold was the temperature of the satellite. The satellite has no atmosphere to exchange heat with, and spends about 50 minutes in raw sunlight (remember how hot a tool gets when left in the sunlight) and 40 minutes looking at cold space at a temperature of about minus 300 degrees. So, balancing and averaging out these two temperature extremes is crucial.

We did what calculations we could regarding temperature control. We wanted to isolate the electronics package from the outer shell as best we could, so we suspended the electronics and instrument package by using a micarta (plastic) structure. We tested the effectiveness of this by placing a simulated electronics package inside an outer shell structure in a vacuum bell jar. We heated and cooled the shell by running steam and then liquid nitrogen through copper tubing brazed onto the shell following a 90-minute typical orbital cycle. We recorded the temperature of the electronics package. We convinced ourselves that this arrangement would provide good thermal isolation.

We then tackled questions about the emissivity of the outer shell since this would determine the temperature swings through the orbit. We had to reduce the absorption of the stainless steel shell of the payload. We learned about a white ceramic coating called “rockide”, which could be fused to the metal. We applied the rockide in stripes to the outer surface of the shell, and then ran tests at Berkley in a solar simulator/vacuum chamber to choose the right percentage of coverage.

These are the white stripes seen in pictures of the satellite portion of the spacecraft.

The calculations from these tests showed that the temperatures telemetered from the Explorer were right in the range we needed – that was a relief!

Next came the electronics. We knew a transmitter and telemetry system would be required, so we started work on those. Transistors were newly on the market, so that was the way to go – to minimize power and weight. The telemetry was straightforward – and several

channels would be needed. JPL had a great telemetry group for their missile program, and we enlisted them to design and produce the telemetry decks.

We already knew the shape for the electronic packages, and they ran with that specification.

We had decided to insert two transmitters; and, knowing the bandwidth we could achieve, decided on four telemetering channels for each transmitter.

These needed to go into flat cylindrical packages that were mounted on the same axis as the transmitter.

Now to the transmitter.

This was a challenge.

The official IGY frequency was 108 megacycles (now megahertz), a wavelength not much affected by the Explorer payload and rocket motor. ionosphere that occupied a little quiet piece of the radio spectrum called the “guard band” just above the U.S. FM broadcast allocation. However, there were no transistors yet in production which could work near this frequency.

My new circuit elements staff, which had pioneered the introduction of transistors into JPL, was aware of experimental work on UHF transistors. So we began pursuing some of these for evaluation. We zeroed in on two companies: Bell Laboratories and Texas Instruments.

We contacted them for information and samples. It turns out that both of these organizations were under contract by the Army Signal Corps and our requests could be covered under those activities.

We set about obtaining samples to build our first transmitters. We knew we would have to prioritize this effort because early flight tests of the Jupiter C configuration were already planned, and we wanted to use these as tests of our new satellite communication system named Microlock. We were concerned both with the electrical characteristics and the environmental ruggedness of these experimental transistors. One certainly prefers to use well-developed and tested components for extreme environments such as rocket launches and satellite conditions, but there were none.

We visited both organizations and obtained samples.

My technicians immediately started putting them into www.radioclubofamerica.org | FALL 2019 PROCEEDINGS

operating circuits aimed at developing the Microlock transmitters. Scheduling was underway for the first RTV test launches, which were planned to start in about one year. The transistors worked well in the high-frequency circuits. Preliminary environmental tests (shake, spin, shock, and temperature) proved that even though they were built in the laboratory setting one by one, these devices would withstand the expected environment. So, we built a number of transmitters. These were assembled in conjunction with the development of the Microlock receiving system. One transmitter was prepared for the first RTV test in late 1956. More about the RTV flight tests and the Microlock system later in this paper.

The other necessary components of the transmitter were also developed. Quartz crystal frequency determining elements were needed, and again, we went to the Army Signal Corps for these. We were able to obtain the necessary high-frequency crystals and put them through environmental tests. These crystals were very thin quartz wafers, but they did withstand the environmental testing.

We planned on mounting them right along the spin axis in the transmitter to minimize stresses on them.

Although the frequency specified by the IGY was 108 MHz, we operated the oscillators at 54 MHz and used the second harmonic for transmission.

For satellite operations we decided on two transmitters in the payload. This gave us a measure of redundancy and to use transmitters of two different power levels to aid in tracking. One transmitter was to operate at a 60 mW output level and the other at 1 mW output level. The high-powered unit would be easier to receive by amateur radio operators and the Navy Vanguard minitrack network. The low power unit would require extra sensitive receivers such as the JPL microlock but could extend battery power significantly. These two transmitters

were contained in different structures, each structure containing its own set of telemetry decks. We studied different types of batteries for consideration. We settled on mercury cells and proceeded to run these through a variety of tests. We mounted the batteries in a circle around the outer perimeter of the transmitter structure since they were least sensitive to spin forces in the transmitter. We learned one thing (the hard way) about mercury cells: if there were battery pack short circuits and it quickly heats, it not only explodes, it detonates.

After one battery put a major dent in the ceiling of our electronic shop, we became very cautious.

Now let me turn to the other end of the communication system, the receivers. We know that signals from a milliwatt-sized transmitter at a distance of several thousand miles would require extreme sensitivity. Over the years, JPL developed radio receivers based on the phase locked loop principle. This involved a receiver of quite narrow bandwidth, but used a frequency discriminator system whereby a received signal could be tracked by controlling the local oscillator of the receiver to keep the signal within the bandpass of the IF stages.

Receivers were designed and developed with a bandpass of only 10 Hz. This is a very narrow bandpass considering a signal at a frequency of 108 MHz, and it would undergo a Doppler frequency shift as a satellite went from horizon to horizon of about 4000 Hz. These receivers were designed, tested, and built. The work actually started before I arrived at JPL. My very first experience upon arriving at JPL was to experience a test being conducted on the roof of building 125. A very low power transmitter was attached to a balloon and tracked to the horizon with the test receiver on the roof. Since I did not have security clearance yet, they could not tell me what these tests were about, but I soon found out in the satellite program.

Several Microlock receivers were built under external contract. Plans entailed installation of several around the country should we be given the opportunity to launch a satellite. One was located at JPL itself. One was located in South San Diego County, in so-called Earthquake Valley. The Caltech radio astronomy staff suggested that location since it was very quiet from the radio standpoint. There were no power lines nor telephone lines in the Valley. One receiver was installed by ABMA in Huntsville.

One was installed at Cape Canaveral for launch checkout. And, one was installed downstream in the launch trajectory at Ascension Island.

an amateur Microlock station and did so with the help of JPL (who furnished the antennas) and the number of commercial organizations (who loaned or provided equipment). The station turned out to be the first one to receive signals from Explorer 1 as it first came over the West Coast of the United States!

Several successful tests of the Microlock system were made through the RTV missile tests which ran several thousand miles down the Atlantic missile range. So we felt we were ready.

contacts, we made two “suitcase Microlock” stations that were sent to Nigeria and Singapore. These were used later in the program, but the first Microlock stations were used for various local tests and for tracking the RTV reentry payloads. A number of tests were made locally using tiny transmitters carried by helicopter on horizonto-horizon flights. Most stations had three helical wound antennas in an interferometer arrangement. Mathematics had been developed to determine satellite orbital parameters by using angle-versus-time measurements as the satellite transited the station.

Participation by the amateur radio community was also solicited. A local group of hams in the Pasadena area (the San Gabriel Valley Radio Club) decided to build

Now to fast-forward the story to 1958. As explained in the first part of this article, the U.S. Navy was selected as the official American satellite agency. We and the Army has been shut out and actually forbidden to carry on any satellite work. However, we continued to develop satellite electronics, a communication system, a launch rocket system, and were ready to go.

Then, on October 4, 1957, the world was shocked by the U.S.S.R. when they launched the satellite “Sputnik.”

The U.S. still had not attempted a satellite launch, and this was a major public embarrassment. The Vanguard program was accelerated for an early launch, and in December 1957, on international public television, the rocket rose a few feet from the launch pad, exploded, and fell into a huge ball of flame. So, at this point something had to be done. The Army finally received the authorization to prepare and launch our satellite, and we were given just 80 days to do it. www.radioclubofamerica.org | FALL 2019 PROCEEDINGS

41

Now with the go-ahead to launch a satellite, it had to be part of the IGY, and it had to include credible scientific measurement equipment aboard. We had to quickly select something and integrate it into our payload. Dr. Pickering assigned Walt Downhower (a mechanical engineer) and me to make a quick trip around the country. We looked at existing Vanguard experiment packages that we might incorporate into our satellite and recommended one. We knew almost everyone in the satellite program, and had at least some knowledge of their various experiments.

After looking at more than a dozen potential experiments, Walt and I recommended a Cosmic Ray experiment package that Professor James A. Van Allen had been preparing for an upcoming Vanguard flight. I had always been interested in cosmic rays (JPL had such an experiment as an approved IGY package), but the real determining factor was that Dr. Van Allen knew what we were doing and had already designed his package so the bolt holes would fit either Explorer or Vanguard! So, it was really ready-made for us, and all we had to do was to integrate it into our satellite structure.

It took a couple days for Dr. Pickering to reach Dr. Van Allen who was travelling on an icebreaker near the South Pole launching Cosmic Ray instrumented balloons. However, we did get permission to transfer his experiment to Explorer. I then moved one of his graduate students, George Ludwig, and his family to Pasadena to assist us in the integration. George arrived in Pasadena with a car full of circuit boards, parts and equipment and quickly found a place to live. My boss, Dr. Eberhardt Rechtin, quickly assembled a major task force of

engineers and technicians to construct, test, and prepare to launch the satellite.

All of the launch preparations and actions are described elsewhere, but it turns out that this little Geiger counter in Explorer 1 discovered some areas of intense radiation in the magnetic field lines around the earth. We did not know it at the time, because we had limited tracking capability. All we knew was that from time-to-time the Geiger counter stopped getting data and then shortly afterwards it worked all right.

The full Van Allen package included a tape recorder (built by Ludwig), which would gather and record data for a full orbit, and the recording would be transmitted when it went over a Minitrack station. Van Allenâ&#x20AC;&#x2122;s group had an inkling that something strange was happening

at certain parts of the orbit, but it took Explorer 3 with the tape recorder to firmly establish that the satellite was going through some places that had high orders of radiation.

That was the discovery of what are now called the Van Allen radiation belts.

Explorer 1 carried another IGY experiment, a pair of micrometeorite detectors made Book Cover.

by Dubin and Manring of the Air Force Cambridge Research Center. One was an impact microphone pressed against the outer shell of the satellite, that listened for possible little “pings” if tiny particles hit. None were heard. The other was a group of grids of tiny wires placed around the base of the rocket nozzle. If any of these wires were severed by a micrometeorite, this would show through the telemetry.

One of the wires might have been severed.

This was the beginning of the American space program whereby our satellite Explorer 1 became the free world’s first earth satellite, following Sputniks 1 and 2. The Soviets did us a real favor by launching Sputnik, because

it caused such a stir in this country that significant effort was put into developing a space capability with high priority. One result was the formation of a new agency: the National Aeronautics and Space Agency (NASA). For more on this, the reader is referred to my book America’s Leap Into Space.

THE FIRST SOLID STATE SATELLITES: EXPLORER 1 AND VANGUARD 1 David and Julia Bart EDITORS’ NOTE: This article highlights the first applications of solid-state technology in satellites, accomplished in Explorer 1 and Vanguard 1. The shrinkage of circuit size, reduction in component mass, and miniaturization of both component and circuit volumes proved critical to developing smaller package sizes that could be lifted into orbit. This article focusses on those first transistorized instrument designs.

INTRODUCTION1,2 The space age commenced in earnest in 1957 following the Soviet Union’s unexpected launch of the Sputnik 1 satellite. The United States followed with the Explorer 1 and Vanguard 1 satellites in 1958. Sputnik 1 relied on radio tubes to operate a radio beacon. Explorer 1 and Vanguard 1 relied on transistors to operate the world’s first solid-state scientific satellites. This new technology launched an era when the drive for space applications prompted many leading innovations that eventually culminated in the Apollo missions and man’s first landing on the moon.

THE SPACE RACE3 Sputnik 1 lifted-off on October 4, 1957, and operated as planned. Soviet radio operators monitored the satellite’s progress across the country’s 11 time zones (see Figure 1). News reports stated that anyone with a shortwave receiver could hear Sputnik as it hurtled overhead. While Sputnik 1 did provide scientific data on the density of the upper atmosphere—based on the rate of decay for its orbit and deteriorating radio propagation as it fell through the ionosphere—Sputnik 1 generally is not considered a scientific satellite because it did not carry any specific scientific equipment.4 On November 3, 1957, the Soviet Union launched a second, heavier satellite, Sputnik 2, carrying a dog, Laika (“barker” in Russian, also spelled Layka).5 At the time, Sputniks 1 and 2 gave the Soviet Union tremendous political prestige, and provoked great anxiety in the United States and its allies. Today, historians conclude that Sputnik's biggest impact was to inspire a legacy of space exploration.

SOLID-STATE ENTERS SPACE Sputnik 1 utilized three radio valves in its D-200 radio transmitter but did not incorporate transistors into its radio circuits (see Figure 2). The existing information on Sputnik 2, launched in November 1957, and Sputnik 3, launched in May 1958, is incomplete. George

Ludwig, a central figure in the design of the Explorer 1 scientific instruments, concluded that the Soviets did not use transistors in Sputnik 1, but they did use a few transistors in one of Sputnik 2’s instruments. The much larger launch capacity of Soviet rockets led to an ambivalence within the Russian space program regarding the miniaturization of satellite sizes, because larger rockets easily carried the weight and volume of vacuum tubes and required batteries. In contrast, the smaller American rockets required reduced sizes and far lighter payloads, directly prompting the development of the first transistorized satellites, Explorer 1 and Vanguard 1.6 The U.S. government had been pursuing multiple paths toward satellite development. However, following Sputnik, the government fast-tracked Explorer 1’s development ahead of Vanguard 1. On January 31, 1958, the U.S. Army launched Explorer 1, developed by the Jet Propulsion Laboratory (JPL), which carried a scientific payload. Vanguard 1, developed by the Naval Research Laboratory (NRL), also containing scientific instruments, followed on March 17, 1958. Both satellites successfully introduced solid-state transistor technology into space.

SATELLITE DESIGNS Explorer 1 was much smaller than Sputnik 1 (see Figure 3). It had a revolutionary, bullet-shaped design, 6.73 feet (2.05 meters [m]) long but only 6.0 inches (15.2 centimeters [cm]) in diameter, which was intended to rotate along its length. The key instrumentation and payload subsystems were as follows:7 www.radioclubofamerica.org | FALL 2019 PROCEEDINGS

45

In comparison, Vanguard 1 was even smaller than Explorer 1 (see Figures 6 and 7). It was an aluminum sphere 6.5 inches (16.5 cm) in diameter weighing only 3.2 pounds (1.46 kilograms [kg]). Soviet Premier Nikita Khrushchev disparagingly nicknamed it the “grapefruit.”9 Key features included:10 • An internal cylinder lined with heat shields that contained the instrument payload: a mercury battery, a 10 mW, 108 megahertz (MHz) telemetry transmitter, and a 5 mW, 108.03 MHz Minitrack beacon transmitter.

• A Mallory mercury battery that powered the telemetry transmitter. It had a fixed charge at launch and operated until depletion.

• Six 2-inch-(5 cm)-square windows mounted along the satellite body that enabled 34 solar cells to power the Minitrack transmitter beacon. Each silicon solar cell could produce 1 watt (W) with 10 percent efficiency at 28° Celsius ©, making Vanguard 1 the world’s first solar-cell powered spacecraft.

• Four whip antennas each extended from the cylinder’s midsection, mounted symmetrically. The satellite was spin-stabilized and intended to rotate along its length.

• The forward section included an instrumentation package, and several scientific instruments extended through the length of the body.

• A single Geiger-Mueller tube detector, designed by George Ludwig, detected cosmic rays.

• Micrometeorite detectors used a wire grid that encompassed the aft section of the satellite. An acoustic detector had contact with the midsection.

• Four gauges measured internal and external nosecone temperature.

Explorer 1 carried two transmitters, one with an output of 1 milliwatt (mW) and the other with an output of 60 mW (see Figures 4 and 5). The two transmitters were separate and self-sufficient, with their own power supplies. They were not interconnected in any way except through radiative couplings between the two separate antennas. Explorer 1’s instrument data transmitted continuously in the form of amplitude modulation; however, transmission for ground reception and acquisition occurred at only those times when the satellite passed over the ground receiving stations.

Unfortunately, the satellite’s spin unexpectedly reoriented about its transverse axis, known as “precessing.” This tumbling caused data assembly to proceed more slowly, and caused a modulation in the received signal, which produced periodic signal fading.8 46

• Six spring-actuated aluminum alloy antennas that protruded from the sphere, each one 12 inches long (30 cm) and 3/8 inch (0.8 cm) in diameter. The mutually perpendicular antennas passed through the center of the sphere.

Vanguard 1 transmitted engineering and tracking data, and broadcast the total electron content (TEC) between the satellite and ground stations. Two thermistors measured the interior temperature to track the effectiveness of the thermal protection.

Vanguard 1 had no propulsion system, no attitude and guidance control systems, and no onboard computer. Similar to Sputnik, it simply spun and rotated in its orbit.11

USE OF TRANSISTOR TECHNOLOGY Transistor technology was only 10 years old when the space race began. The poor reliability of vacuum tubes, and the search for a means of reducing power consumption, had prompted Bell Laboratories and AT&T to seek alternative technologies since the early 1940s. John Bardeen, William Shockley, and

Walter Brattain first demonstrated their new “transistor” device made of germanium in December 1947. In 1954, Morris Tanenbaum at Bell Laboratories and Willis Adcock, who worked under Gordon Teal at Texas Instruments, demonstrated a silicon transistor. The change from germanium to silicon enabled the transistor to become a fundamental building block of integrated circuits. By the time Explorer 1 and Vanguard 1 were being developed, only six years had passed since the first announcement of the junction transistor, only three years since the first transistor hearing-aid was

announced, and less than two years had passed since the first commercially produced transistor radio became available. Although the technology was new, transistors and integrated circuits offered a major solution for compressing satellite circuit designs.12

When Explorer 1 replaced Vanguard 1 as the priority in 1957, JPL assumed the lead design role.13 Dr. Henry Richter became responsible for communications and scientific compatibility and for ensuring that satellite transmissions were compatible with Minitrack and Microlock ground tracking stations.14 (see Figure 8)

James Van Allen and his graduate student George Ludwig (see Figure 9), who had been working on Vanguard, became responsible for Explorer 1’s cosmicray experiments and assumed the lead role over most of the internal satellite electronics, operating under the direction of Richter.15 Richter specified that all of the electronic components should be standard commercial items except for the high-frequency transistors and crystal-frequency elements. Richter himself built a transmitter prototype that was used to develop the fabrication drawings for the radio transmitters.16 • The transmitter assemblies were organized into several decks mounted to a lightweight fiberglass 48

cylinder inside the metal satellite shell, and the transmitter structure was machined from Micarta.

• The lowest assembly held the Western Electric (Bell Labs) transistor, the frequency-determining quartz crystal and the audio transistor.

• The next deck held mercury batteries and a telemetry oscillator.

• The antenna connections were located below the battery deck.

• Printed-circuit technology was available, but most components were mounted on posts and terminals. A variety of pressed-on terminals also were used, such as silver-plated terminals for radio frequency (RF) circuits to reduce the resistance in critical circuits.

Ludwig’s earliest satellite designs for the cosmic-ray experiment, first intended for Vanguard, incorporated Raytheon vacuum tubes. The need for high reliability and minimum risk of failure, plus the need to design a simpler package that occupied less space with less weight, led Ludwig to combine operating beacons, micrometeorite detectors, and the cosmic-ray

experiments into one package. Ludwig taught himself the fundamentals of transistor technology based on articles and circuit diagrams appearing in Electronics magazine.

He constructed handmade circuit-testing boards based on intuition and experimentation until the team achieved the final design (see Figure 10).17 The U.S. Army Signal Corps at Fort Monmouth, New Jersey, collaborated on the project, and ultimately produced the power supplies and component parts.18 Explorer 1’s instrumentation required exceptionally low power, and it had to be compact and rugged. Ludwig knew that NRL had used single- and dual-layer circuit boards, state of the art in 1956 for other projects.

Ludwig obtained and used fiberglass circuit boards with hand-drilled holes and hand-pressed terminals, with the component leads wound around the heads of terminals and soldered. Although inelegant, the circuits proved rugged and reliable.19 Explorer 1 purposely included two independent transmitters for redundancy to ensure that it could be tracked, and that it was compatible with NRL’s Minitrack and JPL’s Microlock ground receiving and tracking systems.20 Subcarrier oscillators, the power supply, scalers, and the micrometeorite amplifier incorporated transistors. In total, the basic circuit included 29 transistors, in addition to those in the micrometeorite amplifier. Ludwig included both the new silicon transistors for their temperature stability, and

older germanium transistors for their lower base-emitter junction voltage.21 Richter’s initial design concept for the Explorer 1 transmitters included transistors from Raytheon (CK791, 2N64, 2N328), Texas Instruments (2N335), and Western Electric (WE53194). Richter’s final transmitter designs used Raytheon (2N328) and Western Electric (WE53194). Ludwig summarized the transistors used in Explorer 1’s science and telemetry package. It incorporated transistors from Western Electric, Raytheon, Philco, and Texas Instruments (see Figure 11).22 • Bell Laboratories developed diffused-junction transistors to produce devices with good highfrequency performance and high electrical and mechanical reliability. Explorer 1 included the Western Electric 53194 transistor, a modification of the Bell Labs BTL 2039 transistor, in the low- and high-power transmitter circuits, achieving nearly 25 percent more efficiency in the circuit.23 • Raytheon was an early leader in transistor production during the mid-1950s. The Raytheon 2N64 audio transistor was one of the first types developed by Raytheon to combine hermetically sealed metal cases with improved germanium technology. Explorer 1 incorporated the 2N64 in the subcarrier oscillator circuits.24 • In 1957, Raytheon developed its 2N327–330 series that operated with lower voltages and double

the maximum collector current, used in highgain settings for switching and audio frequency.

Raytheon’s 2N328 was incorporated into the subcarrier oscillators.25 • Philco also developed silicon transistors, and its pilot production began in late 1956. Philco’s 1957 2N496 transistor was used in the high-voltage power supply of the cosmic-ray instrument.26 Later, Raytheon replaced Philco as the supplier, with Raytheon’s 2N790 and 2N239 transistors providing more stable performance.27 • Texas Instruments pioneered commercial silicon transistor production beginning in 1954. Explorer 1 incorporated their 2N335 silicon transistors in the Geiger-Mueller counter and scaler circuit for high-gain performance across a much broader temperature range compared with germanium transistors.28 Explorer 1’s transmitters were fully transistorized to minimize weight and to withstand all expected environments. The low-power Microlock 10 mW radio beacon broadcast at 108.00 MHz.29 Philco supplied the high-frequency surface-barrier transistor in its original circuit designs.30 Bendix and Honeywell also supplied transistors. In the end, a single Victoreen VXR700S tube remained, operating as a regulator tube necessary for the cosmic-ray detector’s power supply.31

SOLID STATE SUCCESS Both Explorer 1 and Vanguard 1 became long-lived, tremendous successes, and both were highly efficient scientific spacecraft.32 The need for miniaturization had been evident from the beginning,33 and the transistor and other miniature components were responsible for the essential reductions in volume and mass that made the satellites possible. One analysis showed that between

1947 and 1967, the weight and bulk of electronics reduced by a factor of 20,000:1.34 By the time of Explorer 3 in March 1958, the total number of transistors in the satellite increased from 29 to 120.35 Industry leaders quickly and proudly advertised their contributions to the new solid-state world of space communications, which was developing in partnership with leading university research centers. For example, Allen Bradley advertised its resistors as being highly reliable by referring to their placement into the Explorer 1 satellite circuits (see Figure 12), and Dr. Whitney Matthews, head of U.S. Satellite Development Program, and William Hall of the Massachusetts Institute of Technology (MIT), inspected the Explorer 1 telemetering device in a photo opportunity to advertise ongoing university and government cooperation (see Figure 13).

Explorer 1 weighed 30.8 pounds (13.9 kg), with scientific instruments comprising 60 percent of its total weight. Explorer 1 is credited with the discovery of the “Great Radiation Belt,” later named the “Van Allen Radiation Belt.”36 Data from Explorer 3, Explorer 4, Army Pioneer 1, and Soviet Luna 1 satellites subsequently identified multiple layers of charged particles surrounding the Earth. The two main belts, separated by a gap, extend from 400 miles to 36,000 miles above the Earth’s surface. These radiation belts trap high concentrations of highly energized electrons and protons, shielding the Earth from particle radiation.37 Amateur radio operators tracked both the Vanguard 1 and the Explorer 1 satellites throughout their useful lives (see Figure 14). Vanguard 1’s solar power source, the first among satellites, gave it a prolonged operational life. Vanguard 1’s tracking data showed that Earth has a slight north-south asymmetry, and the Earth is “pearshaped,” with the stem at the North Pole. Vanguard 1’s radio signals determined the total electron content between the satellite and selected ground receiving stations. Its data also determined upper atmosphere

densities as a function of altitude, latitude, season, and solar activity.38 Despite the early setbacks and U.S. embarrassment over Sputnik, Vanguard 1—and especially Explorer 1— demonstrated that the United States could conduct significant scientific research in space. They also demonstrated that solid-state electronics had become a permanent part of spacecraft and satellite design.

When combined with solar power cells, and eventually rechargeable batteries, solid-state electronics provided the means for making efficient power sources that yielded longer duration times for satellites and future spacecraft.

AFTERMATH Explorer 1 was intended to rotate and spin along its length. Instead, it started precessing (rotating and wobbling) about its second axis after launch.39 This unexpected rotation, up to 750 revolutions per minute (RPM), did affect operations, and one of the four antennas was lost. Nevertheless, Explorer 1’s scientific instruments and radio transmitters performed very well (see Figure 15). Richter considered the performance “extremely satisfactory,” and Ludwig indicated “excellent” cosmic-ray data was obtained.40 During the time the transmitters operated, approximately 1,500 tape recordings were made of satellite passes by 20 earth stations. The satellite’s original expected lifetime was three years.41 Its high-power transmitter operated for 31 days, and its low-power transmitter functioned for 105 days. Explorer 1 stopped transmitting May 23, 1958, when its batteries died.42 It remained in orbit for more than 12 years, circling the Earth 12.5 times each day. It reentered the atmosphere on March 31, 1970, after completing 58,376 orbits.43 Overall, the mission was a major success (see Figure 16).

Vanguard 1 remains the oldest manmade object still in space.44 It continues to orbit the Earth every 132.7 minutes. Original estimates predicted its orbit would last for 2,000 years. Solar radiation pressure and atmospheric drag during high levels of solar activity affected the height of the satellite at perigee, and the

current expected lifetime is now 240 years. Vanguard 1’s battery-powered transmitter stopped operating in June 1958, and its solar-powered transmitter ceased operation in May 1964 (see Figure 17). Since then, it has been tracked optically from Earth.45 www.radioclubofamerica.org | FALL 2019 PROCEEDINGS

Today, 36 satellites and innumerable ground stations provide services to just the United States, and more than 300 communications satellites are now in orbit worldwide. Cellular technology has brought even newer options for miniaturization capable of managing entire personal communications systems comprising voice and data. These satellites operate in lower Earth orbits, only 500 miles above the Earth, far below the Van Allen radiation belt.46 The shrinkage of circuit size, reduction in component mass, and miniaturization of both component and circuit volumes proved critical to developing smaller package sizes that could be lifted into orbit. The successful Explorer 1 and Vanguard 1 programs demonstrated that transistorized miniaturization was essential for putting objects into space, and yielded tremendous scientific discoveries that pointed toward limitless potential for other applications.47 The work of Richter, Ludwig, and the other talented teams succeeded in bringing transistors into space (see Figure 18).

Backup versions of these satellites can be seen at the Smithsonian National Air and Space Museum. In the mid-1990s, Dr. Richter restored a backup version of the Explorer 1 high-power radio transmitter, which is on view at the Steven F. Udvar-Hazy Center in Chantilly, Virginia (see Figure 19). A backup version of the Vanguard 1 satellite also resides at that location. The Vanguard 3 satellite (recovered from the launch crash site) and a backup of Explorer 1 are on display at the Smithsonian National Air and Space Museum located on The Mall in the District of Columbia.

CALL FOR PAPERS & EDITORIAL COMMENTS The Proceedings of the Radio Club of America is known for bringing you a wide mix of papers, ranging from sophisticated technical material to historical surveys of subjects related to electronic communications. RCA also is known for fostering discussion and sharing the viewpoints of its members. RCA is therefore issuing a call for papers and editorial comments for publication in upcoming issues of the Proceedings.

• Antennas and supporting structures (i.e., towers) • Broadband communications • Broadcast

The Proceedings is published semi-annually, and has been issued since 1914. The Proceedings is considered to be the first publication geared to promoting and sharing the intellectual development of all aspects of radio and wireless communications.

Coverage has expanded to include relevant articles encompassing science, technology development, marketing and regulatory topics. We seek articles from knowledgeable engineers, professionals, academics and amateurs who are participating in building future applications, as well as those who want to document the history of relevant technologies.

• Cellular telephony

As a fellow reader of the Proceedings, we would like you to author an article or editorial for publication. We welcome “early work,” even if it is still in the process of being drafted. RCA offers a unique opportunity for you to get an early reaction to important work now underway in wireless communications. It is also a unique opportunity to air your views, inviting commentary and response from the membership.

• Robotics

Please submit an abstract (1-3 paragraphs) including the title, author(s) and contact information, a synopsis of the material to be published, and a note as to why you think the subject is interesting or important to the wireless industry. Authors of papers selected for publication in the Proceedings may be given an opportunity to present at one of the RCA’s upcoming events, such as the annual Technical Symposium. (Note: participants are responsible for their own travel expenses to RCA events.)

OPPORTUNITIES TO SUPPORT RCA The Radio Club of America provides many opportunities to support the organization and its activities. Sponsors can make specific requests or provide funding for general operations.

INDIVIDUAL SUSTAINING DONATIONS Make a difference in how quickly we progress with our many initiatives for young people, young wireless professionals and those in established careers. We encourage any member who is impressed with the operations of the club to make a tax-deductible donation earmarked to sustaining operations. Donations to support our day-to-day operations are critical to our future as an organization. You can also select RCA as your full or partial beneficiary on an IRA, so funds are tax-free to RCA, or set up a monthly donation through a credit card or ACH withdrawal.

CORPORATE SPONSORSHIPS AT SPECIFIC EVENTS Networking is a key reason many of our members get involved and stay active with RCA. Breakfasts, cocktail parties and other social events can be underwritten by sponsors who receive promotional considerations for their donations and heightened visibility to the membership.

3 YEAR SUSTAINING CORPORATE SPONSORS There is a unique set of advantages to corporate sponsors who participate in our three-year program. See our summary of benefits by level of sponsorship.

SCHOLARSHIPS Donate to an existing scholarship fund or create your own and you will be supporting university students pursuing wireless communications as a career.

YOUTH ACTIVITIES The Youth Activities program brings the excitement of learning about amateur radio and vivid lessons in science, math and electronics to middle and high school children in this unique and innovative program sponsored by RCA.

HOW YOU CAN APPLY YOUR DONATIONS A variety of funds are available to support specific goals of the initial donors and RCA operations. Please contact RCA for more information on these opportunities.
