I’ll be operating RSGB Centenary station, G100RSGB with F&DARS on 26/27 July 2013, from a former US Defense [sic] Communications Station on the eastern edge of Ipswich. The site used to be responsible for providing communications for the effective global command and control of US and NATO forces in Europe and South East Asia, before it finally closed in 1992. More details of the history of the station are available from the Suffolk Aviation Heritage Group

FDARS G100RSGBF&DARS will be making this a special club weekend and will be encouraging as many of it members to operate the station as possible. Many of those members won’t have operated a special event station like this before, so please give them a call and help to make it a very enjoyable weekend.

We hope to be operating two or three HF stations, with occasional operation on VHF and UHF.
Locator JO02ob / WAB TM24 / IOTA EU-005 / RSGB Region 12

Watch the RSGB Alerts and Spots or follow G100RSGB on Twitter to keep up-to-date.

As if that wasn’t enough for one weekend, F&DARS will also be operating GB2SAH from the same site, as part of the Suffolk Aviation Heritage Group Military Heritage weekend taking place there on 27/28 July. We’ll switch to GB2SAH on Sunday, after G100RSGB passes to Loughton & Epping Forest ARS.

Update : Thank you to everyone who contacted us, either as G100RSGB or GB2SAH. We had a very successful but exhausting long weekend of radio. We are very happy to have made 1185 contacts as G100RSGB. Photographs are available in my FDARS G100RSGB gallery.

GS3PYE/P on the Isle of Mull 2013

March 16, 2013 Comments off

GS3PYE-P Mull 2013I’ll be travelling to the Scottish Isles with Camb-Hams again this year.

We will be operating GS3PYE/P from the Isle of Mull (IOTA EU-008) on 10-16 May 2013.

Camb-Hams have been activating the Scottish Isles each year since 2008 and we will be retuning to the Isle of Mull in 2013. Thirteen operators will be active on all bands and many modes from 2m to 160m. We will also be active on 472KHz for the first time.

The HF bands will be covered by five simultaneous stations, while the 6m, 4m and 2m stations will have a great take-off towards the UK and Europe from the island’s south-east coast in IO76 square. We will have an antenna elevation system for 2m EME activity and will also be on many of the VHF/UHF satellite passes. WSPR beacons will be operating on most of the inactive bands to help find the best propagation.

Contest operations will take place in 70MHz CW on 12 May and 432MHz UKAC on 14 May.

We will be active on the major social networks before, during and after the trip. You can check on progress or interact with the operators via their blog at dx.camb-hams.com or through Twitter, Facebook and YouTube. Previous trips have generated some great audio and video recordings of the GS3PYE/P signal from around the world. Check the previous blogs and the YouTube channel and see if you can post a better recording.

Please email skeds-2013@camb-hams.com to arrange skeds on the more challenging bands and modes. VHF and EME skeds will also be made via ON4KST and N0UK’s EME Chat. All links are available via dx.camb-hams.com

Update : We had an excellent DXpedition to Mull, making a total of 16226 QSO’s on bands from 600m to 625nm. Photographs are available in my GS3PYE/P Mull 2013 gallery.

Triple Club Contest Success 2012

January 8, 2013 Comments off

2012 turned out to be an excellent contesting year for two of the radio clubs that I enter club contests with. I really enjoy the format of the various club contests because everyone in the team can contribute their various individual strengths while helping to build a great club/team spirit.

Camb-Hams finished in 1st place in the RSGB AFS Super League for Winter 2011-12. The league takes the combined results from six separate Affiliated Societies contests, so it’s a great team effort and a fantastic result. I took part in the three HF legs with the team.

RSGB AFS Super League - Winter 2011-12
                       50  1.8  144  3.5  3.5  432  Total
1 Camb-Hams           968  966  925  901  967  897  5624
2 Bristol CG         1000  983  800  951 1000  828  5562
3 Trowbridge & DARC   871  898 1000  568  856 1000  5193

De Montfort University ARS finished in 1st place in the RSGB 80m Club Championship 2012 (General Club). The series runs from February to July each year on the 80m band, with SSB, Data and CW legs each month, making a total of 18 legs. De Montfort University ARS won the championship for the first three years it was held, in 2004, 2005 and 2006, so it was great to return to the top of the table again. The Championship was split into two sections for the first time this year, with national clubs entering the General Club section and local clubs entering the Local Club section (with all their members operating within 35km of the club’s usual meeting place). Norfolk ARC won the Local Club section with a higher score than the De Montfort University ARS General Club score, so Norfolk ARC take the G5RV trophy. Many congratulations to Norfolk ARC – a fantastic effort involving a large number of their members.

I was really pleased to achieve my own personal goal of entering all 18 legs of the Championship this year to contribute to the De Montfort University ARS team score. Next year, I’ll focus on improving each of my individual scores.

De Montfort University ARS also finished in 1st place in the RSGB 80m Club Sprint 2012. The series runs from August to November each year on the 80m band, with SSB and CW legs each month, making a total of 8 legs. De Montfort University ARS have won the 80m Club Sprint series every year since it was formally run in 2008. I only managed a small contribution to the team score this year, but still enjoyed the legs I took part in.

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.

CUWS in FP

September 25, 2011 Comments off

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 :

FP/M0VFC, FP/M0BLF, M1ACB, FP/M1BXF, FP/G3ZAY

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.
