A bottler of a show and tell meeting at the club this month. Craig Norris, VK3CDN, from Icom gave us one of the first demonstrations of the new 24GHz features of the IC-905 (with transverter). Graeme, VK3CDO, showed a Vietnam era portable military radio set called an A510 which was in beautiful condition. Put beside an IC-905, I think we could tell which radio he'd rather have in damp jungle conditions. Peter, VK3TPM, showed a home brew antenna hoisting drone and a home brew AM tr...

Saturday's meeting will be a "show n tell". You are encouraged to bring along items of interest, projects complete or not, interesting equipment or accessories. Here's a few previews. Graeme VK3CDO will bring an AWA made military radio A510. "The A510 wireless set was a crystal controlled, low power light-weight transmitter-receiver, designed primarily for use by long range infantry patrols. It could be used as a man packed station on the move, in a vehicle, or as a ground station...

Followers of informative radio web sites QRPer and SWLing will be familiar with the prolific Thomas, K4SWL. He lives in North Carolina in the US and has just come through hurricane Helene. The reason I think it's useful to spread his story is that in the midst of widespread damage, amateur radio kept working (of course) and proved to be incredibly valuable. Throughout the storm, our normally quiet repeater systems were buzzing with activity. The traffic became very organized, with hourly...

Brian Richardson VK3CCR gave a very informative presentation about radar covering both ground based and military plane mounted systems. He explained how it works, how interference and unwanted reflections are mitigated and recent developments which have allowed the power to be reduced while improving accuracy. The club had two new members in attendance for the first time, both are interested in getting their licenses. Rather than using the projector and portable screen we took advanta...

Australian QRP and home brew enthusiasts typically subscribe to two fine newsletters, the local Lo-Key from the VKQRP club and the British SPRAT from the G-QRP club. Both are A5 format newsletters packed full of interesting projects and ideas. They are of sufficient quality to stand many re-readings over the years but it's sometimes hard to find an item that comes to mind in the pile. Lo-Key has an index and SPRAT sells back issues on CD or USB key. When I heard of the publication of ...
