A few club members made the trip to the Moorabbin Hamfest which was a terrific show this year. Loads of interesting radios, test equipment, connectors and books were on sale. As well as beautifully restored older gear there was a display of modern Yaesu equipment. Towards the end of the morning's show prices started to come down and some tables were giving away what was left. It's worth staying to the end. Thanks to the organisers for a well run Hamfest, we look forward to next yea...

This month's meeting was a show and tell session where some members brought along recent projects they've been working on. Aaron, VK3AHC, has been working with Meshtastic nodes. The board he's using includes Wifi, Bluetooth, GPS and a 900Mhz LoRa radio. LoRa radios have amazing range for their power and Aaron has been testing by going for a long walk with one of the nodes. John, VK3JCB, needed to wind solenoid coils with 1,200 turns of 0.2mm wire so he built an automatic coil winde...

Jim Gordon introduces Michael Goode An excellent turnout from club members at the latest RAOTC club lunch at the Caulfield RSL. Thanks to the excellent rail service from the north it's not too hard to travel to the big smoke for a gathering such as this. The speaker was Michael Goode, VK3BDL who talked about 'Holiday Dx-ing'. He has travelled all over the world and organised reciprocal radio rights in most places. Another highlight was Barrie, VK3AXK, who was able to spend some tim...
