November Meeting – Test Equipment

At this meeting members are invited to bring along radio related test gear for display and, ideally, demonstration.

Here a list of some of the equipment we’d like to see: Oscilloscopes Signal generators Frequency counters DVMs (digital volt meters) Antenna analysers SWR meters RF power meters R, L, C measuring devices. Transistor testers. Valve testers. “Grid” Dip Oscillators.

As some members may not be familiar with some of the test gear listed above please, if possible, lay on a simple demonstration of the use of the kit you’ve brought along. Not essential but would be good to do if you can. We should aim to share our knowledge and expertise for the benefit of other members, especially those new to amateur radio. So please help to make this meeting a success by taking an active part. Thanks in advance!

Venuw:  The Robin’s Nest, Cheltenham Football Club, Whaddon Road, Cheltenham GL52 5NA.  Doors will be open by 7.30 for a nominal 8pm start.

October Meeting – QRP Evening

Thursday 17th October 7.30 for 8pm at the Robin’s Nest, Cheltenham Football Club

QRP (ie low power) operation is very popular especially among home-brewers. Many QRP enthusiasts belong to the G-QRP Club which has several thousand members and publishes a quarterly journal full of circuits, projects and news of members activities. Membership is only £6 a year. A number of CARA members are also members of the G-QRP Club.

The aim of this month’s meeting is to promote the concept and fun of QRP (ie low power) operation and to share our own experiences with other club members. We’ll do this primarily with a display of QRP equipment and a display of books covering QRP.

Meeting such as these, without a formal speaker, are popular so do come along and enjoy an informal meeting with fellow club members. Your help is needed to ensure a successful meeting – please bring along examples QRP gear, whether commercial, home-brew or ex-military, accompanied by books and any photos you may have of QRP activities. Working displays would be great although problems with aerials and noise may well arise.

 We will be please to welcome visitors and prospective members.

September Meeting

This month Christopher M0YNG will be telling us about APRS – the Amateur Radio Reporting System. He’ll describe some of the uses it can be put to and explain the underlying technology.

The will also be a small side show, the sale of books and bits & pieces.

Thursday 19th September at the Robin’s Nest, Cheltenham Football Club, Whaddon Road, GL52 5NA. Doors open at 7.30 for an 8pm start.

Visitors and prospective members will be made welcome.

Fun Field Day – 31st Aug/1st Sept

We assembled on the Friday afternoon to erect Smurf’s large, ex-Hungarian military, tent for use as the “mess”, to use a military term, and the “loo” tent. Three of us camped on site overnight. Early on the Saturday morning Tony G3YYH arrived to join the VMARS 80m AM net, as he did again on the Sunday morning.

The above photo shows Tony G3YYH in his Landrover preparing to join the VMARS 80m AM net. He had an “interesting” experience that morning. The wiring inside a “dog-bone” cable link between two pieces of his military kit short-circuited, producing a loud bang and lots of smoke. But no humans were injured!

Smurf M0URF, as usual, provided an excellent full English breakfast. Here’s a photo of Peter G3YJE tucking in and enjoying his first meal of the day.

During the morning more members arrived; tents/gazebos were erected and portable stations set-up with varying degrees of success but all with great fun.

In the afternoon yet more members arrived along with a number of family members for Smurf’s barbeque, which as we’ve come to expect was plentiful, tasty and very enjoyable. We were please to see so many ladies present.

Sunday morning saw a few more club members put in an appearance and also a visitor Mike G4IZZ from Gotherington.

Dismantling commenced at noon and we were mostly clear of the site by 2pm.

Many thanks to everyone who turned up to make it yet another successful and enjoyable Fun Field Day weekend. Particular thanks go to all those who helped set-up and dismantle the kit, to Peter G3YJE for the “Loo” tent, to Tim G8PZD for the G5BK signs and the beer and to Rich 2E0KXL for the additional “beverages”. Last but not least a big “thank you” to Smurf M0URF for providing so much of the kit, the breakfasts and the BBQ.

August Meeting – Report

Last month our Chairman Tony G3YYH told us about his trip to Normandy for the 75th Anniversary of D-Day. He went with his friend Martin M0MGA not only to join the anniversary ceremonies but also to take part in VMARS (Vintage and Military Amateur Radio Society) nets.

The first thing Tony said was that he should have started to plan for the trip five years ago and not within the last year! For when they tried to book accommodation no vacancies could be found within a large distance of the site where the ceremonies were due to take place, Not only that but their plan to operate from the nearby D-Day landing beach was not possible because of security restrictions – on reflection understandable with so many VIPs attending the events.

In spite of these problems Tony and Martin had a great time. Prior to the visit Tony had written to a local French dignitary who was more please to provide assistance. Accommodation for part of the visit was arranged in a nunnery, which Tony said was better than some hotels he had stayed in! They had taken appropriate military kit to France and joined in several nets including the VMARS 80m AM net on the morning of the actual anniversary, which turned out to be a large net with some 85 participants. At one stage Tony used his Wireless Set No.46 which Beachmasters had used on the landing beaches, he was heard by at least one UK station with this very low power HF rig.

The above photo shows Tony G3YYH on the left showing his WS46 set to Graham G8XRS, Derek G3NKS and Barry M0HFY.

Tony and Martin attended a couple of ceremonies and functions and were made very welcome. The French, and the especially the locals, are still very appreciate and grateful for all the sacrifices suffered in the battles to free them of the Nazi tyranny. Interestingly the French treated the Anniversary as a celebration whereas the UK contingent saw it more of a commemoration of the lives lost.

It was a well presented, fascinating, informative and enjoyable talk with many excellent “slides” – for which we offer our grateful thanks to Tony. Unfortunately several members could not make the meeting, so Tony has offered to repeat the talk, probably sometime later this year. Watch this space!

July Meeting – Report

July Meeting report

The “On-the-Air” meeting turned out to be very successful and highly enjoyable with a large number of members setting up stations in the car-park or simply operating /M. Unfortunately I don’t have an accurate record of those who took an active part but here the list I do have with apologies to those I’ve missed and for any errors:

Graham G8XRS 2m /M
Rich 2E0KXL 2m /M
John 2E0POE 40m
Peter G3YJE 80m, 2m
Mike G6OTP 4m, 2m
Tony G3YYH 80m from his Landrover with a 40ft telescopic mast
Malcolm G0TMP 2m, 70cm /M
Simon G4SGI 40m with a magnetic loop.
Derek G3NKS 4m, 2m, 70cm
Peter G4ENA 160m /M
Ken G3LVP 4m, 2m, 70cm /M
Alan M0NRO 40m
Smurf M0URF
Christopher M0YNG 80m

Aerials ranged from dipoles and end-fed wires held aloft by push-up telescopic masts to mobile whips. Peter G4ENA flew a kite to carry a 160m wire aerial.

For me the highlight of the evening was being introduced to the use of my smart phone for listening to the Q0/100 geo-stationary satellite courtesy of the BARTC 10GHz SDR receiver at Goonhilly. I heard Graham G3VKV working Frank G3RMD – both stations were in Cheltenham about 2 miles apart yet their signals travelled some 46,000 miles each way to make the contact!

Our member in France for the summer, Peter G4IOA, listened for us on 40m SSB. I don’t think he worked anyone at the meeting but did work Giles G0NXA who was at home in Twyning.

The new “CARA CQ Alert” channel on WhatsApp was used it good effect, helping members to make contact on the various bands. ( If you wish to join the channel please email me at )

Many thanks to everyone who took part in the meeting and especially to those who brought along interesting and impressive set-ups.

July Meeting

Date: Thursday 18th July, 7.30 for 8pm.

It’s a “let’s get on-the-air” evening! Please bring along your mobile or portable, or even hand-held, equipment and set up in the car-park. Demonstrate or simply display your station for the benefit of fellow club members and hopefully make a QSO or three. If the weather is wet then we can do the same indoors perhaps bringing long lengths of coax to feed the antennas outside.

Why not come along and join in this novel event for CARA – and if you can please take an active part. Let’s have some fun. The bar will be open as usual. Many thanks.

If you can’t make the meeting have a listen for members calling CQ on the bands, eg on on 160m, 80m, 70.450MHz, 145.500MHz or on the local repeaters. We’ll try to announce where we’re transmitting on the G5BK@io.groups forum (you have signed-up haven’t you!). The bar will be open as usual.

June Meeting Report

Last month we had the pleasure of a fascinating illustrated talk about Lundy given by Brian G4CIB, aided by his wife Leta G4RHK, both of whom are prominent and active members of the Gloucester club.

Lundy lies in the Bristol channel some two hours sailing time from Ifracombe in North Devon, it’s long and thin island about 3 miles north-to-south and about one quarter of a mile wide. There’s one pub, one shop and one landing stage. It’s had many owners over the years and is now in the hands of the National Trust but leased to the Landmark Trust as they are better placed to renovate and restore the old buildings which had been neglected by earlier owners. The only permanent resident on the island are employees of the Landmark Trust but there are a number properties of various sizes which are available for holiday lets and these have proved to be very popular. The island generates its own electricity using a large diesel engine which normally runs from 6am to mid-night. There are plans for a wind turbine, Lundy is a haven for wild-life, particularly puffins which have thrived since the non-indigenous black rats were eradicated several years ago.

Brian and Leta began holidaying on the island many years ago and quickly become so enchanted by the place that they’ve visited it every year, sometimes twice, ever since. They enjoy walking the island and watching the wild-life. And visiting the island’s pub! Radio gear is usually taken, which has to be lightweight because of baggage restrictions. Operation is usually fairly low-key with sessions around 7 to 9am and 4 to 5pm. Their next trip will be from 21st to 28th September.

The talk was very well received, members found it interesting and entertaining. We are very grateful to Brian and Leta for making the trip to Cheltenham to visit us. Incidentally instead of accepting expenses for their trip to us they asked that CARA make a donation to the Lundy Field Society which the club has now done – a nice gesture on their behalf.
