We chose the BHF due to how Bunny died and it was decided then that we would adopt them as our Charity.

CPSARC once again headed to the Island of Tiree (EU-008) to take part in the RSGB Islands on the Air (IOTA) Contest which ran from 30-31 July 2005. This contest is one of the highlights of the year, an opportunity to run a busy station during this popular contest, from a location where we are made extremely wel-come. The team this year consists of, Cambell MM0DXC, John MM0JXI, Iain MM1CPP, Brian M0RNR, Bob GM4UYZ, Alan 2M0DXC, Landles GM4XZZ, Norman GM4IUS, Innes GM4VJV, Willie MM0WZZ, Gareth M3INO and Gordon MM3JHZ. Three of the team (Willie, Gareth and Gordon) were IOTA newcomers and they were especially looking for-ward to seeing the tales we’ve been regaling them with for the past 6 months or so come to life. The ‘old hands’ were looking forward to meeting up with old friends and re-newing our acquaintance with the magical island of Tiree. Jim GM7LUN was also plan-ning to come with us but at the last minute he was unable to get the time off from his work. In line with the policy we’ve adopted ever since we started going to Tiree, each of the

come in so far it is looking like being a Meal this year. The prominent meal being asked for is Chinese. I will be send-ing out an email when all the replies are in (asked for by the 30th September) and I have had to chance to collate them. Lastly, this month I am once

again looking for your input as I am now starting to look at putting next years monthly calendar together, so what you would you like to see done. I would appreciate a quick re-sponse, as I would like to get it completed quickly so that I can submit it to the radio magazines. Thanks for your help.

Enjoy the newsletter and see you all on video night and the HF Contests. Bob GM4UYZ

team members paid £125 to go on the trip, this covers all the transport costs (which are pretty high by the time you add up the cost of two vans, two towers and 12 team members on the ferry, then add fuel costs). The amount paid also allows the contest group to purchase additional equipment for use by the club during its contests and spe-cial events, this year we bought some single band bandpass filters direct from Dunestar in the States and an new Yaesu G-1000 SDX rotator from GM1RCP’s Wireless Emporium. The group also funded the build-ing of a new towable 60’ tower parts of which were bought at a knock down price by the ever enterprising MM0DXC who spotted it on one of his trips then set about

refurbishing it with new winches and ropes and adding outrigger feet and running gear to make an excellent addition to our contesting arsenal. The 1500lb winches we bought are excellent, they really make short work of erecting the tower. We or-dered three from our supplier, two for the tower and one for MM0CCC, since we came back other members of the team wanted another two,

tea room and scattered sleep-ing bags across the house in an attempt to house 12 guys (Elaine’s mother Irene even gave up her bedroom to give us more sleeping room). With all the stations set up and working, some of the team got on the air to try things out and of course let everyone we worked know we’d be operating in the IOTA contest tomorrow. Once we had eaten dinner we all set out for the pub which is a 10 minute walk from Elaine’s house. We returned much (much) later after an excellent night of Tiree hospitality, several of the team had retired early but they had a rude awakening when the very tipsy remains of the team staggered back through the sleeping quarters at dark o’clock. Saturday morning loomed into view, still fine and dry, the various members of the team staggered from their beds and hangovers and for-tified by another full Tiree breakfast we made the final preparations for the contest, only to find that one of the voice keyers didn’t work properly, a period of poking about with a meter showed that Bob can’t count! Once the wires were reconnected in the right place, everything was fine. The station description is pretty much as before, the setup we use consists of FT1000MP’s, Alpha amplifi-ers, Dunestar filters, GM4UYZ’s homebrew voice keyer and band decoder units, MFJ voice keyers and our custom built headset interface boxes. Bob has everything packed into plas-tic bags which makes it eas-ier to set up a complex sta-tion.

good stuff indeed! The vans and trailers were loaded up with all the equip-ment and aerials on the Thursday afternoon, most of the team assembled at Cam-bell’s home in Tranent in time for setting out around midnight, we intended to meet up later with Gordon who was coming over from Blantyre. However – we had barely got under way when suddenly the vans pulled over, Iain’s van had devel-oped a problem with one of the wheels. We all had vi-sions of the problems we had last year when a wheel fell of one of the towers on the way to Oban, however the ever resourceful Iain made a call to his brother and a cou-ple of spare wheels were rustled up in double quick time (no mean feat at mid-night!) once the new wheel was fitted, we were off again. The rest of the trip went without incident and we arrived at Oban in plenty time for the ferry. Once on the ferry we tucked in to a hearty breakfast be-fore camping outside the bar waiting for it to open at 9am! We arrived at Tiree at 10.30am, and were met at the quayside by Malcolm and a little later by our host Elaine. Its typical of the re-laxed attitude on the island that we were met by a com-plete stranger and promptly jumped into his car for the trip to Elaine’s. Once we had arrived we

(Continued from page 2)

started setting up the station, as in previous years we di-vided into two teams (indoor and outdoor) to get on with all the tasks, building aerials, erecting towers, setting up the radios and the network etc. This year the weather was fine and dry which made life for the outdoor team much easier. However when the indoor team came to power up the network and the radios we were met by our old friend the uncertain earth conditions on the is-land which were causing the RCD for the house to trip. Normally we’ve blamed this on the wet weather but this year it was dry… A quick bit of reorganising later, we connected one station to a different supply and every-thing powered up ok. By this time co-ax’s and rotator cables were appear-ing through windows as the outdoor teams erected their aerials, we got everything connected up and some basic testing done by tea time.

This was something of a record, in previous years we have been struggling with poor weather or equipment faults long into the evening. During this time Elaine had been supplying us with more breakfast, soup for lunch etc so we were being well looked after. Elaine has started a successful tea shop in her new extension but she gladly closes her business and turns the extension over to us for the contest. We had set up the radios in the large

The whole setup is controlled by our computers running NA and its serial network. This gives us rig control, logging and cluster spots. The cluster feed is via the internet fed into another PC dedicated to this task and K1TTT’s wintel-netx program which gathers cluster info from one or more sources and feeds the spots out onto a serial port for the network (and also generates a log file of all the activity for use later). We still rely on a DOS program on a serial net-work because we know it works and how to fix it when it fails. We are considering moving to a Windows / Ethernet environment and making use of logging pro-grams such as Winlog or N1MM but this still requires some development work. So with everything working, we relaxed for a little while before flinging ourselves into the contest. As usual we had divided ourselves into teams and the fastest operators were on at the start (when its really busy). We all made a determined effort to get the most out of all bands this year and spent a lot of time making sure we had a reasonable number of contacts on 80m, 15m and

10m which have never been all that productive for us in recent years. From the log summary Bob published last month (and included again here) you can see we were much more effective on 15m and 10m. However band con-ditions were much better on 20m where we more than doubled our QSO total. All this increased activity has resulted in a huge increase in our claimed final score to 6,334,650 up from 3,629,175 last year. Obviously the con-ditions favour other stations too but we’re very hopeful of improving our position on 2004. Once the contest had ended, we all stared with amazement at the 6 million plus score on the screen, this was more like it! We then set to dismantling the station, packing it all back into the vans for the journey home. Then Elaine sat us all down for a splendid dinner with crab and prawns, piles of roast beef and champagne to celebrate her opening her tea room. Then it was back to the pub for another evening of Tiree hospitality, a pub quiz and loads of drink. The next morning we all enjoyed more filled rolls before saying our farewells and heading back for the ferry home. I’m sure

we all enjoyed our trip to Tiree, the weather was fantas-tic, the hospitality excellent, the contest was great, what more could we want! Thanks once again go to Elaine Williams for putting up with 12 mad radio ama-teurs and looking after us in splendid style, and thanks to the whole team who really pulled together to build and operate the station and find time to relax in the pub too! Until next year… John Innes MM0JXI

Where the trainees come from

Note: Information from all courses up to 3 September 2005. Bob GM4UYZ

Regarding all the training that I have delivered on the respective Amateur Radio Licences i.e. Novice, Foun-dation and Intermediate, the question I keep getting asked by lots of people is the following.

“Where have all the course pupils come from?” To answer the question I thought I would put a table together showing what course they attended, where they came from and how many from that area.

Where have they all come from?

COUNTRIES and LIGHTHOUSES/LIGHTSHIPS WORKED DURING LIGHTHOUSE WEEKEND. As promised last month that I would produce what we worked as regards to Countries and Lighthouses/Lightships when we were operating as GB2LBN during Lighthouses weekend.. Note we don’t look for Lighthouses/Lightships as we see ourselves as being a contact for other amateurs. See below for the list, which shows some nice ones: The following table shows the actual Lighthouses/Lightships that contacted us. As men-tioned earlier we personally do not go looking for Lighthouses or Lightships as our aim is to provide Barns Ness Lighthouse for all the stations that require the lighthouse for any specific awards

Thanks to all who replied about what you wanted for a Christmas Night out.

Information The Cockenzie & Port Seton Amateur Radio Club was formed by Bob Glasgow GM4UYZ in 1984, to help the local amateurs get to know each other. Numbers have increased steadily over the years and now average about 20. Far from being just a local club we have members coming from the Borders, Dumfries, Strathclyde and Fife. The Club meets on the first Friday of every month (Second Friday of January) in the lounge of the Thorn-tree Inn on the old Cockenzie High Street from 7pm till late. The Club is run in a very informal way, there are no fees, no real committee structure, just a group of like minded people doing something they enjoy! This does not mean that we don’t do anything, we en-ter (and win!) contests, train newcomers, hold talks and video nights and run a popular annual Junk Sale. Our newsletter has won the Practical Wireless ‘Spotlight’ competition on several occasions. The Club supports the British Heart Foundation in memory of a member who died from heart disease by donating the profits from events we hold, we have raised over £11,237 since 1994. The Club is affiliated to the Radio Society of Great Britain and holds the callsigns MM0CPS and GM2T which are used for our special event and contest en-tries. We have our own internet domain www.cpsarc.com and club members can get their own ‘[email protected]’ email addresses. The club also has a Yahoo! Group which is used to manage a mailing list.
