Are you efficient?

Every dollar must carry maximum value and return “ o me, running an efficient plant is more

T

of a mindset than it is selecting the right equipment.”

That’s Kevin Trueblood talking. He’s the associate general manager of technology and operations for WGCU Public Media and the owner of KTrue Media Services, both based in Fort Paul Myers, Fla. McLane Kevin also is the president of the Society of Broadcast Editor in Chief Engineers. He shared with me his insights about operating radio technical operations efficiently as part of a new Radio World ebook.

“The approach is to keep your operations as flexible as possible, with every purchase being considered for maximum value and return,” he said.

“A couple of webcams can take your morning show from just an audio show to a video podcast that can open up new revenue opportunities. You may not be able to run a full AoIP plant, but even just a couple of ‘nodes’ or ‘blades’ can give you a great deal more flexibility to distribute and route audio in your facility, and it gives you the tools to control it all remotely.”

Across radio, managers today are required to do more — usually much more — with less — often much less.

“Budgets get smaller while costs go up. For engineers it means you may have to delay capital purchases, take on additional stations or territory, and get creative with your solutions because doing a proper fix may not be doable,” Kevin said.

“More and more, what were temporary repairs become permanent because the budget isn’t there to fix it properly. But this goes back to my previous statement that every dollar being spent needs to carry maximum value and return, so plan wisely.”

An ounce of prevention is worth a pound of cure.

“Spending $500 to maintain your AC unit twice a year sounds like a lot, but it costs way more than $500 to have a tech dispatched at 5 p.m. while you’re off the air due to an overheated transmitter caused by a busted AC unit.

Similarly, that 10-year-old laptop still works, but runs unsupported operating systems that present security risks, and it takes longer to do things than a modern laptop would.”

How can a user extend, say, the life of older transmitters?

“Keep them clean! Take an hour, shut it down, and wipe down and vacuum the insides. Inspect elements for fatigue or damage.

He notes that remote monitoring and automation help engineers be more efficient and reduce the number of site visits.

“Modern transmitters will let you remotely drill down to very specific parameters such as PA voltages, fan speeds and temperatures. So instead of a general ‘fault’ you have a pretty good idea of what the problem is before you get to the site. Similarly, having cameras will let you visually confirm status, circumstances or faults.”

Even with an older transmitter, he said, you can train a camera on the front to help you inspect meters and diagnose faults, which can be helpful to understand why it won’t restart.

“This gives you a better understanding of what tools and parts you will need to correct a problem before you set foot at the site. Combined, being able to take readings

Consolidation could spike if FCC eases caps Brokers muse on what will happen if the commission relaxes ownership rules

M

edia brokers, attorneys and other FCC watchers say Chairman Brendan Carr and Commissioner Olivia Trusty — the 2–1 Republican majority on the FCC — are poised to overhaul local broadcast ownership caps.

At present, in each of the largest U.S. radio markets, a licensee can own up to eight commercial radio stations, and a subcap limits a licensee to owning no more than five on each band (FM/AM) in the market. The caps shrink as market size decreases.

If those limits are relaxed or removed, brokers expect rapid consolidation through mergers, acquisitions or station swaps, not just in large markets but also medium and smaller ones.

The FCC in September decided that as part of its quadrennial rule review, it will consider relaxing or eliminating these limits, though as of press time, the ongoing government shutdown had delayed the comment cycle in the proceeding.

The National Association of Broadcasters and some individual owners have long advocated for easing the limits.

And while rule reviews often take years, experts expect Carr to move much more swiftly.

Scott Flick of Pillsbury Winthrop Shaw Pittman LLP says once the comments are in, it’s “plausible that an order might be released three to four months after that,” though it could take longer “given that the FCC will want to spend the time necessary to make the order as bulletproof as possible in the courts.”

Frank Montero, co-managing partner at Fletcher, Heald & Hildreth, said the broadcasting community “has been screaming for action” and was disappointed when the FCC’s Democratic majority kept radio caps in place in late 2023.

The commission said then that consolidation among radio operators would not allow them to better compete against digital media and that the public needed to be protected against local broadcasters getting bigger.

Montero expects the Carr commission to take final action by the end of summer 2026.

Brokers say broadcast owners are already considering their options and will be poised to act quickly if the FCC acts. They expect some broadcasters will quickly divest in some markets and invest in others.

Greg Guy, president of Tideline Partners, said, “I would expect most of the major groups to act decisively as deregulation opens the door to refocusing their portfolios, either geographically or by market size, to maximize operating efficiency.”

Given capital constraints, Guy anticipates that many of the larger groups will pursue strategic station swaps as a primary method of consolidation.

“Swaps offer substantial cost savings and allow operators to strengthen their market positions without significant balance-sheet impact,” Guy said.

The efficiency gains and margin improvement opportunities from such trades are significant, he told Radio World in an email.

Meanwhile, he said, well-capitalized operators, particularly those in in medium and small markets, are best positioned to be aggressive if the FCC eases the caps.

Doug Ferber of DEFcom Advisors says radio operators in markets of all sizes have been strategizing in conference rooms to decide if they will buy, sell, hold or swap. “Due to the condition of the industry today, few of the existing owners will be buyers. Most will be sellers or swappers.”

He said companies that are in varying degrees of financial distress like Beasley, Salem, Townsquare, iHeart and Cumulus would have an opportunity to pivot around a transaction and revitalize their capital structure.

He envisions iHeart and Audacy as leading the consolidation in large markets via swaps.

“Connoisseur will be active. Keep in mind they have a lot of stations but only in a handful of large markets,” he says. “They will be involved but they can’t take everything.

Nor do they have the money or the assets that would be

swap worthy to consolidate a significant number of large markets.”

He thinks Educational Media Foundation will continue to be strategic as it builds out its networks.

When the FCC opened its latest proceeding, Beasley and Cumulus thanked Carr for taking up the initiative. In 2023 Townsquare Media and Connoisseur told the commission that ownership rules hinder the ability of broadcasters to compete for audience and advertising dollars.

The NAB has proposed that in the top 75 Nielsen Audio markets, a single entity could own up to eight FM stations, with no cap on AM station ownership, instead of the current “subcap” restrictions. It also has asked the FCC to eliminate restrictions entirely on radio ownership in markets outside the top 75.

In previous filed comments, iHeartMedia has said that abolishing limits on AM caps entirely while raising FM limits “could exacerbate the competitive disadvantage experienced by AM radio stations relative to FM stations.”

Industry observer Jerry Del Colliano, publisher of Inside Music Media, says if the commission relaxes the ownership rules, Cumulus and Beasley could be rolled up into a larger group.

“If the cap is lifted, some companies or stations are going to be absorbed by Connoisseur, which is hell bent on buying stations and groups for low prices, even though the upside of linear media like radio is considered remote,” Del Colliano wrote in October.

George Reed of Media Services Group expects swaps from the largest broadcasters, perhaps “involving a lot of stations in a lot of markets,” as companies try to rationalize their market positions and become competitive with digital competitors.

“I think that many broadcasters will see this as an opportunity to ‘go or grow,’” Reed said.

A move by the FCC to adjust ownership caps could also unlock inventory that has been effectively frozen for years, stimulating meaningful deal activity, he said.

Another expert questioned whether private equity still sees an opportunity in radio: “A mature declining industry? It doesn’t appear to me that there is enough return available to attract large-scale private investment,” this observer said.

“There will be a lot of swaps, no doubt, but swapping won’t be enough to completely consolidate the industry under the NAB’s proposal.”

One broker wrote in an email that dealmaking “will surely reward operators with scale, efficiency and

Radio Regulation local presence while pushing marginal operators to consolidate or exit the business. Owners will need to be aggressive to stay in the business and remain a going concern. It could accelerate the divide between viable and non-viable stations.”

Consolidation also could affect non-broadcast businesses that are tied to radio.

One observer said, “Ratings really won’t matter in smaller markets. Over the span of an ad campaign, a radio company will be able to deliver the entire market to advertisers if they own all or most the stations in the area.

In many ways the industry will go back to selling radio on its merits, i.e., its ubiquitous reach, economic price relative to other media, and the results provided to advertisers. Sell your Nielsen stock now.”

“” Due to the condition of the industry today, few of the existing owners will be buyers. Most will be sellers or swappers.

“Long Overdue” Larry Patrick, operating partner of Patrick Media Brokerage, is in a unique position to comment on what’s ahead if the FCC eases ownership limits. He also owns Legend Communications, which operates 22 stations in northern Wyoming. He wrote the following to Radio World: This is a critically important time for the radio industry to ask for significant ownership deregulation. If the “smaller than 75 market rank complete deregulation” proposal is approved, little will change other than some small operators will exit and others will buy out their direct competitors. Not much of a blip on the national radio market radar.

For real market forces to work, there needs to be almost total ownership deregulation of the industry from top to bottom. Private equity and investment money is not interested in buying collections of unrated markets. They want scale and a way to enter the national market in a big way. The industry has spent a decade cutting costs, laying off personnel and hoping for a miracle. That hasn’t occurred.

For an industry that is 100 years old and facing competition from huge companies backed by public shareholders or private equity, the fact that these artificial barriers to ownership exist is contrary to basic economic theory.

Let radio build the scope of its operations and scale necessary to compete with the TV networks, Meta and Google, and dozens of new streaming and digital services. We are long overdue for a complete revamping of the ownership controls imposed by the FCC. Localism will still exist as the benchmark of good radio. Stop crippling radio by the controls of artificial ownership caps. Let the market decide our future and be brave enough to steer our industry forward. This will result in higher multiples, the scale to survive in an over-abundant media world, and a future for the best operators and investors to thrive.

Newswatch

C-BAND: The FCC in November was expected to propose a rulemaking that would auction additional midband spectrum in the upper C-band.

It would allow the FCC to take an important step towards implementing actions mandated in President Trump’s “One Big Beautiful Bill Act,” which restored the agency’s auction authority and requires it to complete a system of competitive bidding for at least 100 MHz in the upper C-band no later than July 2027.

The proposal is likely to be opposed by broadcasters because some of the spectrum is used for satellite delivery of TV and radio content.

The notice of proposed rulemaking would seek comment on a range of options, including auctioning up to 180 megahertz of spectrum in the 3.98–4.2 GHz band for next-gen wireless services.

The FCC said it will consider “all options within that range, with the ultimate goal of maximizing the amount of spectrum to be repurposed as generational aviation safety upgrades occur in the adjacent band.”

Carr said the Trump bill “authorizes and requires the FCC to auction prime, mid-band spectrum in the upper C-band, and my proposal aims to maximize the amount of spectrum available for 5G and 6G services.”

rchie Simpson read our discussion about using duct tape to remove a dead floodlight bulb. But what if the bulb is already broken, with the filament stem and sharp glass poking out of the socket?

As engineers, we might reach for our toolkit but Archie offers an alternative: Grab a potato!

After turning off your power, simply slice off and discard one end of the potato, then shove the rest of the tuber, cut edge down, into what’s left of the bulb. Then turn it. The bulb remains should unscrew easily.

If this doesn’t work, it may be time to just replace the fixture. The part will be inexpensive and easy to swap out.

Archie used floodlight fixtures with built-in motion sensors.

He adds that you can prevent sticking by lubricating the threads of the replacement bulb slightly; however, do not use petroleum-based lubricants or flammable compounds.

Instead, apply a small dab of dielectric grease to the threads of the new bulb (not to the end contact).

An NPR affiliate recently experienced problems with a relatively new satellite downlink. The average Eb/No and AGC numbers were low, sometimes to the point where the receivers unlocked for extended periods.

At first the engineers thought local 5G carriers might be operating slightly out of band. They replaced the LNB and put in a new 5G filter, among other things.

But it turned out that the station’s contractor had done a substandard job of installing and aligning the dish itself. The engineers tweaked the polarization adjustment (using nothing more than the receiver Eb/ No reading), which took it from 9.1 to about 13.5. They had to rotate the LNB about 30 degrees to get the system operating properly, so the alignment hadn’t even been close.

A frustrating experience after hiring what you thought was a professional company!

Before the snow blows

If you maintain an AM facility, here are some things to check at the base of each AM tower before cold weather sets in. The tip is courtesy of Larry Wilkins, technology director for the Alabama Association of Broadcasters.

At base of each AM tower is an antenna tuning unit.

The ATU matches the impedance of the transmission line to the impedance of the tower, for maximum power transfer.

Start by visually inspecting the ATU inside and out. With the RF power off, ensure that connections are tight. Inspect components for signs of overheating or lightning damage.

You want to keep rodents, snakes and wasps out.

Scatter a few moth balls in the bottom of the ATU cabinet and apply some repellant like the Mouse Magic we’ve mentioned before.

Wasp spray along the edges and eaves of the cabinet will discourage the flying critters. But the best prevention is to seal all openings. Note, insects can get in even through small empty bolt holes cut in the enclosure.

Use a light to check for holes. Most ATU cabinets have an AC outlet; plug a trouble lamp in, close the enclosure door and look for light leakage to detect holes. (Remember, turn the RF power off before doing this work.)

“End of the Road Radio” enjoys a new birth WELY Radio is back on the air in Ely, Minn.

Mark Persons The author wrote earlier this year about a visit to PJB3, a Trans World Radio AM station on Bonaire.

Above Ely is a former mining town in northern Minnesota.

T

he future of WELY Radio in Ely, Minn., was uncertain in May of 2022 when the Bois Forte Band of Chippewa said it would soon go silent.

After a short reprieve, its final day was Nov. 30, 2022. The licensee reportedly had put $1.7 million into the station since 2005.

WELY(AM/FM) sat silent while Zoe Communications of Wisconsin had it, but in February of this year Civic Media purchased the station, with a solid plan to put it back on the air.

The company has about 30 radio stations, mostly in Wisconsin, where it is based. It emphasizes local content, as its name suggests. The CEO is Sage Weil, a successful software engineer and executive from California who moved to Madison to be a broadcaster.

History

I have a personal connection to this station.

My father, Charles B. Persons, did the engineering work to launch an earlier station, WXLT(AM), in the city, completing the necessary FCC measurements on a New Year’s Eve in the late 1940s.

But WXLT was unable to pay its bills in this tough ironmining town, and it went silent after about two years.

But Dad would be back. He decided to leave a good corporate engineering job at the Arrowhead Radio Network — which had about a dozen stations in Minnesota and Wisconsin — because he felt the urge to own a radio station himself.

He applied for and received a construction permit to build WELY on the same 1450 kHz frequency, on the same

150-foot tower and in the same building as WXLT. He moved the transmitter and studios from the main floor to a walkout basement, and our family, including four boys, lived above.

WELY went on the air Oct. 11, 1954. It started as a shoestring operation but quickly won over the hearts of the local community to become profitable.

The station was referred to as Broadcast House. You could address a letter to Broadcast House in Ely and it would be delivered. Coverage outside of town was poor, with only 250 watts in very low soil conductivity. However, it was the only radio station in the town of 5,500 people. The signal did not need to go far as there wasn’t much outside of Ely. My father had a 20-minute “fireside chat” for listeners on Sunday afternoons called “Hello Neighbor.”

Charlie would talk about things at the station and around town, steadfastly refusing any commercial endorsements for the program.

Listeners knew they were getting the inside story, much like the broadcasts

by President Roosevelt during the Depression and World War Two. An interesting note is that my father talked the FCC into allowing thirdparty messages. This was long before cellphones or any telephones in the wilderness area surrounding Ely.

Above Fig. 1: Charles B. Persons, the author’s father, at the WELY microphone in the 1950s.

Below Fig. 2: WELY’s tower and studio in 1995.

Announcements were aired at a scheduled time each day, usually messages from families and friends of those camping. A message might say, “John Donovan, your brother Frank had a heart attack and is in a hospital in Albany, New York.” The tradition continues today — this wilderness area has virtually no cell service or internet.

Two iron mines kept locals employed, especially during the war, when the mines operated 24/7. Our family left the area in 1959.

The town of Ely eventually became a tourist destination, at the edge of what is known by the U.S. Forest Service as the Boundary Water Canoe Area Wilderness. This is where Minnesota and Canada come together in beautiful camping and fishing waters. There are now 3,268 Ely residents.

The photo below shows the station in 1995. The tower proudly sported WELY call letters. The studio has since moved downtown; today the house and original tower are privately owned. The W was removed, and the tower sign now says ELY. The AM transmitter was moved to a nearby tower (see Fig. 3) in the early 1990s and runs 770 watts fulltime nondirectional on 1450 kHz. They cut back from 1,000 watts because the tower is taller and thus more efficient.

WELY-FM, 6 kW on 94.5 MHz, was added in 1992. It is off the air as I write this in November, but as soon as a tower crew arrives, the latest change will make it 35 kW using a Bext eight-bay antenna and a Nautel transmitter.

As you can see on the next page, the tower is shared with a cellular company, so typical in today’s world.

End of the road

Roads leading to Ely come from the south and southeast.

You don’t drive through Ely to get somewhere. That is how WELY became known as “End of the Road Radio.”

Ely is only about 16 miles from the Canadian border. It is known as the Gateway to the Boundary Waters as well as the Canoe Capital and Sled Dog Capital of the U.S. Take your pick, they are all recreational activities.

The station chocked up a checkered past since 1954.

WELY closed briefly, then reopened in 1995 when CBS journalist Charles Kuralt of “On the Road” fame bought it after falling in love with Ely. This brought some notoriety to the station. The station was sold after he died in 1997. Later the Bois Forte Band of Chippewa purchased WELY. The station went through frequent format changes.

You’ve seen it before — a broadcast owner with no programming experience changes the format to suit his or her liking. The result is usually bad news.

Listeners and sponsors go away and it is a struggle to get them back.

The newest owners seem to represent a fresh start for WELY(AM/FM). Small-town stations have a better chance of succeeding than those in larger cities because they can be programmed with local news and events. There is polka music on Saturday mornings that the town people love. No changing that in a community where descendants of northern European immigrants have lived for many generations.

The nearest town with a radio station is Eveleth, Minn., some 50 miles away. However, there’s competition from six FM translators in Ely.

Civic Media brought WELY(AM) back to life in the spring of 2025, but the inoperative FM transmit antenna needed to be replaced; that project stalled when it was said a tower stress study had to be done but then was deemed a “repair,” so work could continue. Meanwhile 1450 kHz WELY AM continued, much like it had 71 years ago. It is hometown radio with heart-warming music and good voices.

Broadcast engineer Erick Burnstad, above, was at the studio when I visited recently. He is one of five engineers employed by Civic Media.

Erick hails from Portage, Wis., but enjoys going from station to station.

He has his hands full with transmitters and converting automation systems over to ENCO. Station Manager Terri Pylka was born and raised in Ely. She and three others worked together previously at WELY and are excited to be working together again as part of Civic Media, an organization that values and supports community radio. Terri is passionate about the community while building good business relationships.

And morning announcer Craig Laughery goes by “Trader Craig” for items he lists for sale on the air. He interviewed my wife Paula and me live on WELY for half an hour one morning. We related history stories to the staff and listeners. Speaking of listeners, at least five people stopped in while we were there to visit and show their appreciation for WELY returning to the air. That is small-town radio!

Civic Media says it aims “to champion the practice of democracy through the power of honest and informative local voices.” The programming lineup includes local

football, volleyball, basketball, ski meets and especially hockey. A translator for WELY(AM) is on 103.9 MHz and you can listen online at: https://wely.fm/. You can also find the station on Facebook.

My father’s book, “Where Have All the Broadcasters Gone?” has “The Ely Years” in Chapter 7. The book is out of print; however you can hear the audio, absolutely free, as narrated

by Kirk Harnack, at http://mwpersons. com/old-radio/books.

The heated liquid is pumped outdoors and through a heat exchanger with a fan blowing on it, much as in an automobile cooling system.

After a few years installing and working with liquid-cooled transmitters, my feelings about them are mixed. There are situations in which they make sense, but others where the downsides outweigh the ups. I’m sure there’s plenty of room for debate.

The installation of a liquid-cooled transmitter is much more complex than that of an air-cooled type. Important tasks include running hoses, putting on connectors, connecting pumps, installing heat exchangers (concrete

pads?), leak testing and filling the system with fluid. Your maintenance program will involve the pumps, hoses, liquid tests, fans and heat exchangers.

Control and monitoring must consider the pressures and temperatures of the liquid and operational parameters of the variable speed pumps and fans. Most of this is monitored by a complex system, and cleaning and repairs of liquid technology require knowledge of such systems that a broadcast engineer may not already possess.

What’s the upside? The most obvious is removal of heat from the transmitter and less heat load in the building.

About 67 percent of the heat of a transmitter is delivered outdoors to the heat exchangers.

Liquid cooling means less air must circulate through the building; operation can be cleaner and quieter.

Another major factor is the cost of electricity. We find many estimates of what power will cost us in the future, but it is unlikely to cost less.

Tech Tips Any good analysis of transmitter costs must include all relevant factors both internal and external. An analysis of building cooling needs in Tucson will not be useful for a transmitter site in Bangor.

Air conditioners have their own maintenance and upkeep issues including filter cleaning, recharging, fan motors and monitoring challenges.

Thought starters

Here are some questions with which to start: Is the transmitter building already full and hot? Is there space adjacent to the building for heat exchangers? Can the heat exchangers be secured from vandalism?

Will there be significant savings in the costs of cooling the building by using liquid, or could you use readily available cool fresh or air-conditioned air?

Is altitude a factor? Air cooling requires more air moving through a transmitter to dissipate heat at higher elevations than at lower elevations.

Transmitter technological advancements come at an astounding rate. Improvements in the efficiency of power supplies, amplifiers and other components make any analysis done with older designs irrelevant. More efficiency means less heat loading. Liquid- and air-cooled designs create similar amounts of heat; the difference is how the heat is dissipated.

Kevin Haider of GatesAir recommends that when you are calculating electricity consumption and transmitter power, you should consider the possibility that you could add HD Radio channels at some point.

More HD means higher transmitter power and more heating load in the building, so you may wish to futureproof by designing a transmitter system and site that are robust enough to handle such changes without expensive facility upgrades. Haider suggests that liquid-cooled transmitters may fare better running near full power than equivalent air-cooled transmitters.

Liquid cooling is practical in an age where virtually every critical parameter can be monitored and controlled. But it’s important that someone who knows how to maintain the system is involved. A reliable engineer can pick up the basic skills, but do the research and consider how you will support your system.

And everyone I’ve talked to in this area strongly recommends that when it comes to the actual installation, bring in someone with experience in liquid cooling. While I like to handle projects myself, even I can tell that liquid cooling is not the time to “go it alone.”

I’ll return to this topic in more detail soon. Meanwhile, what’s your experience with liquid vs. air cooling? Drop us an email. Write to me via radioworld@futurenet.com with “Liquid Cooling” in the subject line.

Tech Update Nautel Highlights the Software-Based Air Chain Nautel notes that traditionally, an HD Radio air chain was a long line of boxes including encoder, decoder, audio processor, importer, exporter, Exgine card, exciter and maybe a monitor, all connected by cables and rack space. Each function had its own dedicated hardware and configuration.

“Today, that traditional chain is being transformed by software,” the company says.

“We’ve created the ability for broadcasters to have the entire air chain embedded — from input to RF carrier — inside the transmitter itself. Alternatively, all or parts of the air chain will be able to be hosted on an industrial grade server.”

The company says a software-based air chain approach means you can “just add audio.” Everything else including the processing, the HD coding and synchronization are handled in software running in the transmitter platform.

Beyond eliminating boxes and cabling, the FM and

HD signal paths can be synchronized with no need for monitors or correction algorithms.

“This integration brings remarkable flexibility, and by virtualizing the air chain, multiple redundant air chains can be created if desired.” This can be done instantly, often remotely, without swapping hardware or rewiring.

Also, updates can introduce new capabilities over time.

“Should any of these processes need to be supported by 64 bit architectures in the future, the software-based air chain will be ready.”

Nautel says fewer external components means greater reliability, lower total cost of ownership and less physical infrastructure to maintain.

Tech Update BYO With ScreenBuilder by Wheatstone The ScreenBuilder touchscreen development suite enables a user to add onto a WheatNet IP audio networked facility with little more than a touchscreen without having to add panels, knobs, boxes or cable.

“You can create a producer panel for controlling mics during a busy show, or add a complete news workstation with automatic gain, source selection, intercom and full mixing from one menu’d touchscreen,” Wheatstone states.

These touchscreens can be useful for signal routing, sharing codecs across studios or locations, or providing a quick intercom between studios and venues. One screen scripted to do several things can repurpose a studio for production one hour and for a talk show the next.

“Choose from controls, clocks, faders and dozens of other widgets, and apply basic scripting using Script Wizard for a variety of functions.” Or you can add your own widgets and specialized scripts for more customized screens.

Creating your own touchscreens gives you the flexibility to generate content anywhere and to tap into the WheatNet IP audio network for controlling mics, cameras or codecs or for automating routines. Digital and streaming services can originate specialized programming through software without adding physical rooms to manage those additional mixes.

Wheatstone also offers full virtual consoles such as the Glass LXE that can be used independently or complementary to a physical LXE console, with real-time fader tracking between the two.

Tech Update Arrakis Offers Two Approaches to Virtualization “A prime example of complete virtualization is the Arrakis DARC Virtual AoIP console,” Arrakis states.

“This product reimagines the mixing desk as a pure software application. Instead of a physical board with faders and knobs, the DARC Virtual runs entirely on a standard Windows PC.” This allows it to be a powerful, full-featured mixer controlled from a screen. By leveraging AoIP protocols like Dante or standard ASIO

drivers, it manages mixing, routing and processing in the digital domain. The software-centric design supports remote broadcasts, broadcast studios or backup systems and offers control from anywhere with a network connection.

For those needing a physical interface, the DARC S series provides buttons and faders to control the software.

Separately, Arrakis says its H-series consoles represent a hybrid solution. These are professional analog consoles that provide the tactile feel, familiar workflow and analog signal path preferred by man users.

“The innovation lies in their digital control for added flexibility. Both the 10-channel H-10 and 15-channel H-15 connect to a PC via USB, running the H-Series Controller software.”

The software does not process the audio; it controls the console’s internal routing and logic. This supports digital features such as complex user presets, remote monitoring of levels and the ability to control audio levels and channel assignments. An operator can reconfigure the board for a different show with one click.

Broadcast networks for the next era New York Public Radio deploys Seeker SD-WAN

Vinay Purohit Founder/CTO CloudJuncxion

Steve Shultis CTO New York Public Radio

Below A broadcast network depicting diverse WAN links and multiple Seeker deployment options.

roadcasting is in the middle of a rapid transformation. Audiences demand flawless content delivery across more platforms, while broadcasters face relentless cost pressures and the need to modernize infrastructure.

Traditional networks, built on expensive private circuits, rigid topologies and manual operations are increasingly unfit for this new environment.

Seeker SD-WAN provides a fresh and transformative approach for how networks are envisioned, built and operated. Purpose-built for demanding broadcast environments, it combines software-defined networking (SDN) with military-grade self-healing and security, while reducing deployment and operational complexity.

Broadcasters such as New York Public Radio have embraced Seeker to simplify their networks, cut costs and dramatically improve resilience. The result is an overall network with lower expenses, significantly lower over-theair outages, and improved agility required to thrive in the digital-first era.

Hitless transmission

Broadcast networks have long relied on leased fiber and MPLS links to deliver content reliably. But these private

circuits are costly and inflexible, limiting a broadcaster’s ability to expand or adapt quickly.

Seeker SD-WAN removes this dependency by intelligently aggregating affordable consumer-grade broadband, LTE/5G and Starlink connections, while also supporting P2P microwave links when available. The result is hitless transmission at the same or better performance while lowering costs.

By replacing costly traditional transport, New York Public Radio cut operating expenses while simplifying its network footprint. Broadcast audio quality also saw a big improvement as NYPR was able to switch to uncompressed audio feeds direct to transmission sites instead of using compressed audio.

Broadcast-grade resilience

Reliability is non-negotiable as outages erode the customer experience and, consequently, revenue. Viewers and listeners expect uninterrupted, high-quality programming that’s impervious to network impairments.

Seeker SD-WAN was designed with distributed intelligence — instead of centralized routing controllers — for hitless transmission, ensuring seamless content delivery even during disruptions of transport links to transmission sites.

Key resilience features include:
