A well-attended and engaging meeting today at Woodend.
Joe, VK3MAB, gave a detailed overview of the state of the art in low cost SDR reception. He showed a variety of client software including SDR#, SDR++, and many others.
Excellent HF recordings were played as well as DMR recordings of airport workers who can be heard from Joe’s place.
He demonstrated reception of 433MHz devices including a garage door remote. A UHF FM transmitter was demodulated. A fascinating a wide-ranging presentation.
Graeme VK3CDO showed a Meshcore setup using his Android phone and a Heltec V3 device. Messages were exchanged between he and Richard, VK3LRJ both direct and via the #public channel.
Peter VK3TPM spoke about recent success using Claude Code to greatly assist in ham radio projects including a python script to convert a WAV audio file into an IQ file for sideband transmission on a HackRF.
Also he discussed recent progress in translating FreeDV RADEV1 from python to C which has resulted in a functional application that both receives and transmits while being a fraction of the currently shipping FreeDV GUI app.
After the meeting some of the group retired to a local cafe for further discussion and a scrumptious lunch.
