At the next meeting we’ll hear two short talks, each lasting about 30 minutes, given by club members.
Peter G4ENA will present an illustrated talk called “Radio with Ropes Attached” relating his interesting experiences operating on the HF bands from his canal boat.
The second talk will be by Alan M0NRO on 3D printing – those of us who saw his “products” at the Constructors’ Exhibition will confirm that this talk will be well worth seeing.
The meeting will take place at 8pm on Thursday 18th April at the Robin’s Next, Cheltenham Football Club, Whaddon Road, GL52 5NA. Doors will be open by 7.30 for an 8pm start.The meeting will take place at 8pm on Thursday 18th April at the Robin’s Next, Cheltenham Football Club, Whaddon Road, GL52 5NA.

CARA’s annual Constructors’ Exhibition took place on 21st March, a meeting where members show items they’ve built at home during the last year or two. We were treated to a very interesting range of exhibits many of which were constructed to a high standard.
Here’s a list, in no particular order, of the items on display:
A partially complete LV and HV power supply for vintage ex-military equipment such as the BC-348 receiver and the Collins ART-13 transmitter – shown by Tony G3YYH.
A QRP Labs QCX 5W CW transceiver for 40m built from a kit (some 6,000 such kits have now been sold) – Peter G4IOA.
A range of products, including antenna insulators and small cases, produced by his 3D printer – Alan M0NRO.
A portable power unit with solar panel for use with an IC-706 HF/VHF transceiver – Christopher M0YNG.
A demonstration of Mastodon, a Twitter-like app specially adapted and promoted by the exhibitor for radio amateurs world-wide – Christopher M0YNG
A components tester which tests and measures transistors as well as resistors, capacitors and inductors, assembled from a kit – Derek G3NKS.
A CFR (Controller Feeder Radiation) half-wave vertical dipole for 2m for use with his motor-caravan – Derek G3NKS.
The judges, Jon M0JMM and Roger G3REB, made the following awards:
The Bill Brown Cup for Best in Show to Peter G4IOA for his superbly built QRP Labs kit transceiver.
The Pat Moore G3IKR Memorial Cup for Innovative Construction to Christopher M0YNG for his novel portable power unit.
The Roger Kendall G0UPU Memorial Cup for best Computer/Software related Project to Alan M0NRO for his 3D printer project.
Many thanks to all the exhibitors, the judges and everyone else who attended, we had an enjoyable and successful evening.
The Table Top Sale on 21st February proved to be another popular and well attended meeting. The tables were well populated with items for sale, including antennas, linear amplifiers, hf and vhf transceivers, computers and test gear – plus lots of bits and pieces such as components, cables, tools and mast hardware. Something for everyone perhaps!
Some sellers were content but others reported that trade was disappointing. However that’s how it goes! Your reporter has often taken stuff to several rallies in succession without out any interest being shown in the kit, but then at the next one it sells easily!
We were pleased to welcome to their first meeting – Dom M7PKW and Shaun M6OII. We look forward to seeing them again soon.
The new venue again proved its worth, being comfortable with good acoustics.
The next meeting is the Constructors’ Exhibition on Thursday 21st March at the same venue, the Robin’s Nest, Cheltenham Football Club.
Thursday 21st February at the Robin’s Nest, Cheltenham Football Club, Whaddon Road, GL52 5NA. Doors open at 7.30 for a nominal 8pm start.
Sellers – please display your wares (related to radio or electronics) on one of the tables and sell to the assembled multitude! Bring a large cloth, eg an old blanket, to cover the table to avoid damage. Sellers must be members of CARA
Buyers – come with well loaded wallets and have some fun buying items you didn’t know you wanted!
Visitors and prospective members will be warmly welcomed.
Michael G3PCL has kindly agreed to tell us about Baluns, devices which connect unbalanced coax to a balanced antenna. Different types of Baluns are discussed together with circuit diagrams and constructional details. Suggestions are made as to which Balun type to use with a particular balanced / unbalanced antenna. There will be lists of suitable components to use to make your own Balun and several home made Baluns will be on display.

The CARA’s 42nd AGM took place on Thursday 13th December 2018 with 32 members present.
Tony G3YYH, Chair, reported a successful year highlighting many notable events including two enjoyable Fun Field Days, Foundation and Intermediate courses with high pass rates, a fascinating visit to Ben Nock’s Military Wireless Museum and a good display of home-built equipment at our annual Constructors’ Exhibition.
The Bernard King Memorial Cup awarded for noteworthy and praiseworthy on-the-air activities was presented to Tony G3SNN for his superb DXCC scores achieved over many years of sustained effort. The John Holt G3GWW Award for exceptional work for the club went to Smurf M0URF for his outstanding contributions to Fun Field Days.
The Treasurer, given the healthy state of the Association’s finance, proposed that the annual subscription remain at £13. Approved unanimously.
The Committee for the year 2019 was elected. Chair – Tony G3YYH, Secretary – Derek G3NKS, Treasurer – Peter G3YJE, ordinary committee members – Andrew M0MVA, Alan M0NRO, Christopher M0YNG. Accounts Examiner – Tony G3SNN.
Any Other Business. Tim G8PZD queried whether a decision had been made regarding the move to a better venue for our monthly meetings. Two venues were contenders, one tried in November and one suggested at the meeting. The Chair asked that, following further investigations, the Committee be allowed to make the final decision regarding the move – this was agreed. Tony G3SNN proposed a vote of thanks to the 2018 Committee for their good work and to the Editor, Christopher M0YNG, for producing such excellent newsletters every month.
Following closure of the formal meeting members enjoyed a light finger buffet and lots of chat.
The “Skills Evening” held on 18 October proved to be very popular, with one of the highest attendances so far this year. Six members manned tables around the room to demonstrate, explain and talk about an aspect of amateur radio – usually one which was a particular interest of theirs.
Ken G3LVP explained how make properly make-off coaxial connectors such as BNC and N-type, with examples and supporting diagrams.
Peter G3YJE demonstrated a “Tuna-Tin” QRP transmitter, showing the output waveform on a ‘scope. He was also promoting the American Radio History website to which he has been contributing for several years.
Paul 2E0IFV had a display of DMR radios, including hand-helds, and demonstrated their use.
Tony G3SNN showed his fine collection of exotic QSL cards for his 160m and 6m activities.
Barry M0HFY had a live demonstration of FT8 (one of the latest data-modes which is currently very popular), making several contacts during the course of the evening.
Mike G4GUG was extolling the virtues of Linux, and telling how well this Operating System would run on older machines.
Each of the tables attracted a gathering of members for much of the evening, and much general and lively chat took place as well.
Very many thanks to the six members who kindly “volunteered” to man the tables and indeed to everyone else who made an appearance; you all contributed to the undoubted success of the meeting. We were pleased to enrol Chris M6NZC as a new member and John 2E0GCR who re-joined after an absence of a year or two.
Thanks once again go to Alan M0NRO for kindly manning the kitchen. Thanks also to the several members who, without being asked, helped clear away the tables and chairs at the end of the evening – your efforts are much appreciated.
