SPECIAL POINTS OF INTEREST:

Well here I am writing this editorial even before the July club night and VHF Field Day as I am about to go away for two weeks holiday with one of them in hopefully sunny Tenerife. Unfortunately by the time this is being read I will be back home and it will all be a piece of history. Ok then what have we been doing this month? First of all we will have taken part in the RSGB VHF Field Day, hopefully there will be a report on how it went for either this or next month‘s newsletter. To come is the IOTA contest from TIREE as I write this but by club night it will again be history. No doubt there will be many tales to tell. To the future, well the

major event is our Junk Night on the 8th August. I am again looking for raffle and food donations so if you can help I really would appreciate it. Let‘s hope is once again a resounding success as it has been in previous years. Also we have Lighthouses Weekend on the 16 & 17th August once again down at Barns Ness so I hope you will all come along and take part and have what is a real fun weekend. The Foundation Courses once again start this month with the first one fully booked and the next one in September nearly full. After that I am still looking for Foundation Recruits so if you know of any then please pass them on and I can get them booked on a

course. The Morse assessments are as always available on demand but there are rumours as I write this that the Morse requirement is disappearing so maybe there won‘t be a need for this soon [see page 4] No real topics this month to chat about, I am sure there will be but they elude me at the moment so all that has to be said is enjoy club night, come along to Junk Night and Lighthouses Weekend. See you all then. Bob GM4UYZ

CLUB BBQ A relatively late decision was made to hold a BBQ and the date decided was the longest day, 21st June. Typical the weather in the morning was abysmal to say the least with the good old summer weather of raindrops falling from the sky being prevalent. Any way the decision to still go was taken. Glad to say that later on the weather cleared and the sun came out along with the dreaded midges but it was rather cool. Who said it was midsummer‘s day? The choice of venue taken was up past Horseupcleugh just of the Gifford to Longformacus road. Now in hindsight better instructions should have been given as a few people had difficulty in finding the site, or even not finding it at all. We live and learn. Cambell MM0DXC and his son David made there way up to the site midmorning and set-up the Club Tent followed shortly by Alan MM3SLK and his partner Claire. Later on after a frantic phone call to find out directions RON GM0NTL and his wife Sylvia 2M1FMX joined them. Yvonne and I could not go early due to

granddaughter baby sitting duties but managed to get there for about 19:30 just in time for the BBQ to start. Whilst on route I received a phone call from Ron GM4IKU saying that he and Aileen, his XYL couldn‘t find them but after giving directions they eventually found the site. A little bit later Liz 2M1GLD and then Iain MM1CPP joined us. The BBQ and chat was certainly flowing freely with ―the mobile disco‖ doing its job. The real event of the BBQ was Iain getting bogged down literally in a bog. He had taken young David for an off–road drive around where we were then suddenly he just came to an abrupt halt. Comments were ―He‘s stuck, no he isn‘t, oh yes he really is‖. Various methods were tried to pull Iain out but alas we didn‘t manage. A frantic call was made to one of Iain‘s offroad pals to come and pull him out. Fortunately he was doing a disco at Longniddry and said he would come up after that. Back to the BBQ and the music and await Iain‘s pal arriving. He arrived

at 02:00 and after a bit of connecting up power to his winch at the front of his Landrover and tying himself to a huge post Iain‘s land rover was pulled out. Believe it or not there is a video of the whole event courtesy of Liz so any one wishing to see it please contact Liz. After this some off us decided to bed down for the night where others stayed up and chatted. Not everyone stayed the night, Ron and Sylvia had left in the early evening, Ron and Aileen went late evening and Alan and Claire went after Iain was pulled out and the rest of us stayed. On the whole it was a real enjoyable affair, apart from the midge bites. If we could only guarantee the weather we could certainly have a few more BBQ‘s. Those who didn‘t come along well what can I say. Bob GM4UYZ

AMATEUR RADIO ESCAPES MOBILE PHONE BAN

The Department of Transport has issued a paper on the results of its consultation on a proposal for the introduction of an offence of using a hand-held mobile phone while driving. The consultation document suggested that ―two way radio microphones‖ should be included within the proposed ban, which would effectively have banned mobile amateur radio in the UK. In its submission to the consultation document, the Radio Society of Great Britain pointed out that

amateur radio had been operated from motor vehicles since 1955 without any accidents being recorded. The Department of Transport report on the results of the consultation states that ―Amateur radio operators, some commercial drivers such as taxi drivers and hauliers, and some of the emergency services use [two-way radio] to communicate with a base station. We accept that such ‗press to talk‘ devices keep conversations short and are likely to have a lower

Club BBQ at

risk… While the details of the extent of the exemption remain to be determined, the new offence will exempt the use of such devices‖ [conversations short? who among us hasn‘t timed out a repeater? - Ed]

REMOVAL OF MORSE REQUIREMENT FOR HF Following the World Radio Conference held on 9 June 4 July Chapter 25 of the Radio Regulations has been re-written and simplified, allowing administrations to remove the Morse requirement for allowing Amateur HF operations. The UK has agreed to implement this and the Gazette Notice to implement the changes to the licensing Terms, Provision and Limitations Booklet will be issued as soon as possible. From the date of the Gazettes (27 July 2003) all Class B licensees will have full privileges contained in the BR68 and BR68/I as appropriate. New Validation Documents and RA publications reflecting these changes will be issued on annual renewal. Class B licensees need not take any action to obtain these privileges. These privileges will be granted automatically. These changes do not affect Foundation Licensees All amateurs holding either a Full Class B or an Intermediate Class B licence have been granted Class A licence privileges. If you hold both classes of licence you may continue to use whichever call sign you wish, as long as the associated licence has not expired. When your licences expire, you can choose which one you wish to maintain and renew – you will then be

issued with a new Validation Document for that licence. You do not need to take any action to cancel your other licence and call sign – they will lapse automatically if the Radio Licensing Centre (RLC) does not receive your renewal payment. You cannot change your Class B licence into a Class A as your current Class B call sign now has the same privileges as a Class A call sign. If you currently hold a Class A call sign, but wish to apply for your old Class B call sign you will need to provide RLC with proof that the old call sign was issued to you. Acceptable documents include either an old Validation Document or photocopy of your entry in an old RSGB Year Book/Call Book. (You do not need to provide this proof if the call sign lapsed within the last 10 years and can be identified on the RLC database.) You must also complete a licence application form and pay the licence fee of £15. If you hold a B Class licence and an M3 licence. You will not need to renew your M3 (Foundation) licence, but you will need to maintain your Class B licence in order to operate with full class privileges. The RA has informed the Radio Society of Great Britain (RSGB) that a Morse testing service is no longer required in the UK. However,

the RSGB will continue to conduct Morse proficiency tests for amateurs wishing to go abroad to countries where Morse is still a requirement (see below). The Morse Assessment is still a part of the Foundation Licence course? If you‘re visiting a CEPT country you will be able to operate below 30 MHz with your current Class B call sign if the country concerned has dropped the Morse test requirement from its amateur radio licence. If the country retains a Morse test requirement, you will need a Morse test pass certificate, or you will continue to operate as a CEPT Class 2 licence-holder. We advise you to obtain confirmation from the authorities in the country you will be visiting. If you‘re visiting a non-CEPT country which recognises/ accepts only amateur licences of a Class A category you will need to take a Morse test to apply for a reciprocal Class A licence.

Morse is removed as the barrier for access to HF

VHF FIELD DAY—MM0CPS/P The Club entered the RSGB VHF Field Day from our usual site at Mainslaughter Law. As always this contest requires a large amount of equipment drawn from all over the club. The caravan which the club purchased from John MM0CCC was in operation in its new guise as a radio shack. All the interior fittings have been removed and sturdy shelving has been installed, giving room for up to 4 stations. The convoy that made its way up the hill on Saturday morning included two caravans, a tower and several cars, I had just arrived a little after the main body only to discover that we

were missing vital parts of the 2m beams, so I turned round and drove back to Tranent to collect the parts. Once I got back, the stations were well under way, we were planning to run four stations over the weekend, 2m, 70cm, 6m on Saturday and 4m on Sunday. The 2m and 6m stations were run using Yaesu FT100MP‘s and transverters, the 70cm station was using a Yaesu FT847 and the 4m station was using a Kenwood TR751 and transverter. We had some problems with the 2m station which appeared to be caused by a defective patch lead (see John‘s article about feeder losses below).

The weather closed in on us shortly after the stations were set up and we continued in almost zero visibility. So much so that when the cars from the Jim Clark rally passed by after midnight, we could only hear them thunder by, not see them. I wasn‘t able to stay overnight or return on the Sunday but from what I‘ve heard, a good time was had by all. The conditions were not great, thank goodness for voice recorders! John MM0JXI

VHF Field Day.

FEEDER LOSSES Having grumbled several times about RG213U/UR67 (and similar) being unsuitable for use on VHF and above, I thought I'd better do some experimenting to determine how true this statement actually was. I have a number of different types (and lengths) of co-ax at home so, equipped with a power meter and dummy load, I decided to measure each for power loss. I chose 144MHz as the band to do the tests, and the results are listed in the table on page 10.

This certainly makes interesting reading. Admittedly it was the longest cable run at 50m, but I was astounded at the power loss of the RG213U.

RG213U! Even if only used for HF, I think I'd pay the extra £10 per 100m drum and buy H100, or and extra £20 for Westflex W103.

[to keep things in perspecJohn MM0CCC tive, I‘ve added a loss / 100m column for all the cables—Ed]

A scary thought to ponder...last year, at VHF FD, we nearly used a similar length run of RG213U on 70cm until Bob GM0BWU came to the rescue with some LDF4-50. I shudder to think what power Power out from the transmitwould have reached the Yagi ter was 10 watts. if we'd stuck with the

CPSARC 20M CONTEST RESULTS This year the contest was run on Wednesday evening the 18th June between 19:00 and 22:00BST and once again we were blessed with a lovely dry evening. The contest rules were changed this year to accommodate the Foundation Licences plus the possibility of the chance for more QSO‘s. The later didn‘t happen as 20M displayed it like how 10M has been doing over the past few years, dead. Although saying that some nice DX was worked with Lebanon and Iraq being present.

few points away. Personally Caroline 2M1HVR who was partnering myself had a real bawl working what stations we did. She certainly went away at the end of the evening on ―cloud 9‖ on what she had worked, and at the end of the day that is what it is all about. Although we call it a contest if there was the chance of passing on a good DX station to the others it was done giving everyone the chance to work it. Basically a real fun night.

Thanks to everyone who took part espec iall y Steve MM3SRU & Isa MM3ISA, although they only had 3 QSO‘s due to an extreme local QRM source (external modem) they at least put on a Foundation entry and gave the contest ago. Cambell‘s partner was Alan MM3SLK and Caroline 2M1HVR was mine, great to see them go out as well. To next year then.

A total of 7 club callsigns The results are printed be- Bob GM4UYZ were active although some low: only took part just to give a Pos

ECHOLINK DTMF CODES I was asked a little while ago by Vic GM4GGF, how to send alphabetical letters using a DTMF keypad on the echolink system (you need to do this to call a station if you don‘t know its node number) A bit of raking about the internet and a flash of inspiration late ... To enter a callsign using DTMF you have to encode the letters by entering two numbers which correspond to where the letters appear on a DTMF keypad, you enter the first digit then a second digit which corresponds to which letters are on each key 1 QZ

CLUB DXCC A club member asked me where do we stand with regard to the number of DXCC countries worked, non-confirmed and confirmed. This was quite easy to obtain as I keep separate logs, one for Contesting and the other for Special Events. Contest Log: This log starts on 3/10/1999 when we obtained the club callsign MM0CPS and stands at 23483 QSO‘s logged up to 6/7/2003.

CPSARC Log:

DXCC Worked – ALL BANDS, ALL MODES is 121 with 73 of these confirmed. The QSLing strategy for this log is that I always QSL 100% and what is very surprising is that we have not made our DXCC but I suppose we are 13418 QSO‘s short but to be honest I thought we had done better than we have. Interesting though! Bob GM4UYZ

If I receive a QSL card then I do return one so in all fairness I don‘t think we are doing too badly with regard getting the 100 countries confirmed to claim a DXCC. This log starts on 29/9/1990 and stands at 10065 QSO‘s logged up to 15/6/2003.

CONTEST COMMENTARY August is not a particularly busy contesting month here in the UK. The only VHF event is the RSGB 70MHz Trophy Contest. This can be a rewarding contest to participate in from Scotland as, with the main centres of population a good distance away, most QSOs are worth plenty of points because of the 1 point per km scoring rule. This often results in several English groups travelling North to take part from GM-land to increase their chances of winning the contest. With reasonable equipment it is therefore possible to do well from an elevated site in this area.

PoCo 2 Contest which is an 80m CW event. RoPoCo stands for Rotating Post Codes which gives a clue as to the contest exchange format for this one! You start at the first QSO by sending the usual RST report plus your own post code then for each subsequent QSO you send RST plus the post code you received in your previous QSO! Confused? You will be if you give it a try! This is a very good test of your CW sending/receiving skills and it can be interesting listening to see if you receive your own post code, or part of it, back again from someone later in the contest! Not a contest for the faint hearted but good The only other event of note fun all the same! this month is the RSGB Ro-

Finally, a brief reminder of two events early next month. Just after September club night it is time again for IARU Region 1 HF SSB Field Day and also the RSGB 144MHz Trophy Contest! Both are excellent events and have regularly been entered in the past by club members. They run almost concurrently (with a 1 hour offset) and can both be entered at once if you have enough manpower! Give them both a thought when you are planning next month's activities! 73 and good luck in the contest! Colin GM0CLN

The Cockenzie & Port Seton Amateur Radio Club was formed in 1984 by Bob Glasgow GM4UYZ, to help the local amateurs get to know each other.

We are on the web at www.cpsarc.com

Numbers have increased steadily over the years and now average about 33. Far from being just a local club we have members coming from the Borders, Dumfries, Strathclyde and Fife.

COCKENZIE & PORT SETON AMATEUR RADIO CLUB

The Club meets on the first Friday of every month (Second Friday of January) in the lounge of the Thorntree Inn on the old Cockenzie High Street from 7pm till late.
