GS3PYE/P & GS6PYE/P on the Isles of Mull, Lunga, Staffa & Iona

May 13, 2012 Comments off

I had an excellent week with 16 other Camb-Hams on a DXpedition to the Isles of Mull (EU-008) and Lunga (EU-108) on the west coast of Scotland, using the call signs GS3PYE/P and GS6PYE/P. We also managed short trips to the Isles of Staffa (EU-008) and Iona (EU-008) using other call signs during the week.

My own personal highlight of the trip was the 24 hours I spent camping on the uninhabited Isle of Lunga, with four other Camb-Hams, two radios and lots of puffins. We visited the Isle of Staffa on the way back to Mull and operated for an hour as MM0MJH/P on 20m.

Another fine memory was carrying loads of kit up a hill on Mull so that I could witness my first (and only) ever 10GHz contact. Luckily there was some fantastic scenery to look at while waiting for contacts.

The weather during the week was great and the radio even better.

UBN Report for RSGB 80m AFS CW

March 2, 2012 Comments off

The UBN Reports are out for the RSGB 80m AFS CW Contest which took place on 8 Jan 2012.

My own UBN report is copied below. I’m really happy with only dropping 3 QSO’s (30 points) because I don’t really ‘do’ CW and need a lot of help and concentration to even follow the very predictable contest exchanges. Two of the ‘broken’ serial numbers are very understandable (85/95 and 28/128) but what was I thinking when I mistakenly logged 111 instead of 165 ?

I finished with 147 adjudicated QSO’s for 1470 points, to make a small contribution to the Camb-Hams B team for 26th place in the contest. The Camb-Hams A team did really well this year, finishing in 9th place. Both teams making a significant improvement over last years placings. A good contest and I’d encourage others to give it a try.

1st Place for DMUARS in RSGB 80m Club Sprint 2011

December 11, 2011 Comments off

The result of the RSGB 80m Club Sprint 2011 contests have been announced and I’m very happy to say that the team I play a small part in has finished first again. De Montfort University ARS have now won the contest series for four years in succession to retain the Newbury Trophy.

I followed the activities of six operators from the Cambridge University Wireless Society operating as FP/homecalls from Saint Pierre et Miquelon at the end of September. I was lucky enough to work them on 15m, 17m, 20m and 40m during their activity when they were great signals into the UK.

Mark M0MJH recorded a video which included my QSO with Rob FP/M0VFC on 17m :

I also recorded an audio file of Rob FP/M0VFC on 17m last night just after I’d spoken to him :


Dom FP/M0BLF, Martin FP/G3ZAY, Simon FP/G4EAG, Tom FP/M0TOC, Rob FP/M0VFC and Gavin FP/M1BXF were all active, making over 17,500 contacts during their stay and also regularly posting  news and videos via their Facebook and Twitter feeds direct from the island.

I managed to speak to all of them except FP/M1BXF, so I just missed my own target of ‘worked all operators’. I did however win the competition the team set, giving them the correct answer during one of our contacts. I collected the competition prize of a kit radio from Signal Hill, Newfoundland at the Camb-Hams Pye & Pint evening this week.

I’m looking forward to hearing more about the DXpedition during the RSGB Convention this weekend.

2nd Place for DMUARS in RSGB 80m CC 2011

August 18, 2011 Comments off

The results of the RSGB 80m Club Championship 2011 have been published.

Congratulation to Bristol GC for maintaining their strong lead throughout the Championship. But the great news, as far as I’m concerned, is that De Montfort University ARS managed to fight off a very strong challenge from Norfolk ARC to finish in second place this year.

5   Three As CG                    85368 44167 24869 16332

I joined the De Montfort University ARS almost ten years ago and have been lucky enough to play a small part in many contest-winning team entries since then, collecting at least one team contest trophy every year, except for 2007 if I remember correctly.

It’s now time to concentrate on the RSGB 80m Club Sprints for 2011.

A busy couple of weeks

August 10, 2011 Comments off

It’s been a really busy couple of weeks so I haven’t had much time to post anything here. I think that’s a good thing because the ‘doing’ is more important than the ‘writing’. I’m still short of time so this post isn’t going to be filled with details and deep thoughts, just a brief note of some of the things I’ve been doing and a few pictures to go with them …

Back Garden UKAC

July 11, 2011 Comments off

I have been active mostly on HF recently, but the VHF NFD re-ignited my interest in the higher bands, so I decided to put up a very temporary antenna and make a few contacts in the RSGB 144MHz UKAC contest last week, just for fun. I used to take part in the RSGB Backpackers contests a few years ago, so I dusted off the 6m aluminium mast but couldn’t find my portable 9 element Tonna antenna for 2m, so I decided to put together the 2m halo antenna I’d had for years and never used.

I got everything together, with the help of some cable ties and tape, connected the Yaesu FT-897 on the garden table and … it started to absolutely poor with rain. I did manage a few brief contacts while the rain was running down my neck but I quickly decided to give up and try again another day. It was fun, but maybe more fun next time.

Update … I had another go tonight for the RSGB 432MHz UKAC. I put my very small 70cm beam on the mast, got the radio out and … it rained again. I’m sure the RSGB are working with the Met Office to co-ordinate contests and weather !

Maybe next time.

UBN Reports for RSGB 80m Club Championships

July 5, 2011 Comments off

The RSGB Contest Committee have started issuing UBN Reports for the 80m Club Championship contests. This is a very welcome addition to the already excellent on-line log submission and quick adjudication we have enjoyed for these contests.

UBN Reports highlight contest contacts which were judged to be Unique, Bad and Not-in-log during adjudication and can be used to help improve the accuracy of your logging. I received an email today with a link to my UBN report for the May RSGB 80m Club Championship CW contest, which highlighted exactly why I lost one of my claimed contacts during the adjudication process.

I had a great weekend with the Camb-Hams operating G3PYE/P from JO02ed on 6m, 4m, 2m, 70cm and 23cm in the RSGB VHF NFD 2011. It’s hard work preparing, assembling, operating and disassembling a competitive station for this contest, but the Camb-Hams put a lot of effort into collecting some great equipment and operators and still manage to make it a lot of fun.

It was nice to get back together with many of the people who I travelled to the Isle of Arran with a few months ago for some more great radio.

Lawrence M0LCM and Dom M0BLF have both posted some photographs of the G3PYE/P contest site and G7HAH/P have posted a video of them receiving G3PYE/P.
