This evenings meeting was just pencilled in as a ‘noggin and natter night, but we started with a bit more of a radio theme…..
Stuart, G0TAL has decided to get rid of some of his old radio equipment that is sat gathering dust in the attic, but before being listed on eBay, it needed testing to ensure it worked ok….
To this end Ian, G7DWY brought his Bird Thruline power meter and Doug, G4DZU provided an element to cover the HF bands.
The radio was then tested on transmit into a 50ohm dummy load, and the results were pretty good with the radio delivering its full rated output on the HF bands, but being a little down on VHF – it probably needs a little tuning.
We then connected it to the club aerial and verified reception on the HF bands.
The meeting continued, debating many diverse subjects, not all radio related, but all of interest.
As the meeting was finishing, I turned up the volume control on the club HF rig and had a tune around 17m (18Mhz). One call got a response from Tony VE3AXW in Brantford, near Toronto in Canada. Not bad for a non resonant dipole and 100w!
This evenings meeting has been a talk by Doug, G4DZU about time and frequency standards.
The talk focused on Doug’s quest for a reliable frequency standard, and how this had progressed from his early forays on 2m in the early 1970’s, and the acquisition of different types and accuracies of standards through his amateur radio life, culminating in the current standard locked to an accuracy of 1Hz in 10Ghz – useful for 23cms EME!
Doug then went on to cover how to lock modern radio equipment to a GPS based frequency standard and the importance of time synchronisation in modern digital modes – very enlightening.
Please feel free to come along to any of our organised talks, and many thanks to Doug for this evenings informative and interactive presentation.
Another nicely attended meeting this week, even though there was no official talk.
A few visitors and prospective members as well as some of the regular Stalwarts. Once again John, G3TSA brought an interesting piece – a 1980’s band three power amplifier. These were installed up and down the country and formed the trunked mobile radio service.
Andy G4XKC paid us a long overdue visit and was discussing his portable antennas that he used to good effect in the UKAC’s last year.
Come and pay us a visit and join in the ‘banter’….
Thursday 7th February we had a “Night on the Air” with Doug, G4DZU and John, G3TSA bringing some interesting pieces of equipment along for us to look at. We were able to compare a modern, inexpensive L/C meter with a more traditional, and much more expensive, model, see a versatile “spy” video camera and a Raspberry Pi computer.
Thanks also to Ian, G7DWY for bringing along his KX3 and demonstrating it to visitors. A very enjoyable evening.
