RSGB Convention 2016 update

Camb-hams FlossieMyself G0RVM and Peter 2E0UAR attended the RSGB Convention in Milton Keynes this year.  We left Bristol around 15:30hrs but got stuck in jam after jam.  Towards the end of the journey ‘here comes another set of blue lights’ was becoming a bit of a joke!  Fortunately we did arrive before the buffet dinner finished.  It was a close thing tho as there where only a few slices of pudding pie left 😉

This was my first Convention and I must congratulate the RSGB for such a great event.  The accommodation was good, the food and conference facilities excellent.  It was educational to hear talks on a variety of subjects from speakers deeply knowledgeable in their subject.  Access was free to those under 21yrs too – a great way of incentivising attendance by younger radio amateurs.  Thank you RSGB.

In addition to the rooms hosting five parallel lecture streams there was a room with stands by Icom, Kenwood, the RSGB and of course, Martin Lynch who were the prime sponsor.    Outside this room was a rather large trailer tower with HF antennas providing live signals for the exhibitors.

Kenwood TS-990Proudly parked outside the front of the conference centre was Flossie, the mobile radio van of Camb-hams.  Protruding through its roof was a Clark pneumatic mast with rotary HF dipole.  The van looked excellent and a great way to get a portable setup to a distant location, setup and on-air with minimum fuss.  As I have a pneumatic mast also it was good to swap experiences, finding we shared some of the challenges associated to these masts.

Some of my favourite talks over the weekend were:

    • The new world of amateur satellites, Graham Shirville, G3VZV
    • The Story of SDR and FlexRadio, Gerald Youngblood, K5SDR
    • The VP8SGI & VP8STI DXpeditions, Mike McGirr K9AJ
    • Space Weather, Prof. Cathryn Mitchell, M0IBG.

I was really looking forward to “Best practice for VHF UHF DX” by Ian White GM3SEK but unfortunately Ian had to cancel.  Maybe next year.

Camb-hams FlossieFrom the first talk identified above I learnt that we as radio amateurs are soon to have a ‘bend-pipe’ transponder in geostationary Earth orbit.  Wow that is an amazing feat and I can’t wait till its operational.  Amazing.  The talk by Prof. Cathryn Mitchell was excellent being delivered superbly and hugely informative.  It was interesting to hear how in 2015 space weather was identified in the UK National Risk Register with an impact of the same scoring as emerging infectious diseases, inland flooding, effusive volcanic eruptions, major industrial accidents etc.  In fact, in 2015 the likelihood of a major space weather event occurring in the next five years was in the second from highest category.

I can thoroughly recommend attending the Convention and I know I will be booking my 2017 ticket as soon as they become available next year.

RSGB Convention 2016

RSGB ConventionThe RSGB 2016 Convention will be held at the Kents Hill Conference centre in Milton Keynes again this year on the 8th and 9th October.  It is a weekend of lectures spanning many topics of interest to all radio amateurs. The RSGB have now released a draft programme for Saturday and Sunday which I have included here.

If you are under 21yrs you get free entry too. 🙂

Peter, 2E0UAR and I, G0RVM are going.  Are you?

Happy Birthday Severn Bridge

Paul, M0ZMBThe Severn bridge was 50 years old this month.  To commemorate its birthday the Thornbury and South Gloucestershire Amateur Radio Club (TSGARC) ran a special event station with the callsign GB4SBB throughout Thursday 8th September.

The morning arrived, the weather gods smiled upon us, a very nice morning, a little too much wind perhaps.  The first arrivals were on site and unloading by 09:00hrs, put up the tents and started to erect three HF antennas, this took time, a lot of time during which Mike Davis G0JMD arrived popped up his posh toilet tent, a pole complete with a white stick and was operating on air within fifteen minutes. ( Lesson. Keep it simple, practice erecting poles and antennas and to have a plan and to stick to it ).  It became clear that a Special Event Station is not the place for experimenting…..

The day, however, turned out to be a success with 50+ contacts were made and we had visits from passing amateurs, also a member from the Chepstow ARC drove across the Bridge specially.

It was great to see so many of our club members, some stayed a hour or so, the rest were there for the all important break down.

Special thanks must go to Ron M6EAT for supplying the Generator, Stan G0RYM for the big dome tent, we would have made more use of it had it rained.  And to all the Club members who made it a day to remember.

VHF (2m) gets busy…

2m VHF

Strange hot weather but good conditions on 2m 🙂

Monday 5th and Tuesday 6th September very busy on 2m.  At times tonight every 10kHz step and often 5kHz step was busy.  Great to see/hear.  Worked F8IQS in Caen on CW.  His signal was easily 599!

Even bumped into another club member, Steve, M6JJV working contest from Berkeley 🙂

Celebration of 50 years of the Severn Crossing GB4SBB special event.

TSGARC members will be setting up a special event station on the east side of the bridge at the  Brightside observation point on Thursday 8th September 2016 at 9.30am  transmitting until 5.30pm. We have set up  a page on Qrz.com for information. Rob and Sue will be handling our qsl cards and John m0hfh will be looking after the qrz log and page. We will be pleased to see members or non members interested in this event at the observation point on Thursday.

The institute of civil engineers is also celebrating this event on the west side of the bridge.
