Just received my Raspberry Pi 5 and planning to migrate my current Pi 4 setup that runs WSJT-X, fldigi, and a custom Python script for automatic antenna switching based on band selection. Has anyone tested Andy's Ham Radio Linux on Pi 5 hardware yet? My current Pi 4 setup occasionally drops PTT timing on FT8 during high CPU usage. I'm particularly concerned about audio interface reliability - several club members have had problems getting audio out from Pi to transceiver, with radios going into TX but no signal being received. Looking for real-world performance comparisons and any GPIO timing improvements with the Pi 5.

The Pi 5 alpha release needs about 6.5 GB and has been tested on Raspberry Pi OS versions 5.1 and 5.2. Installation restrictions will be relaxed once the user community provides feedback. I'd wait for more beta testing before migrating a working setup.

Been running Pi 5 with KM4ACK's Build-a-Pi project - it gives you complete control over the build and allows you to choose applications rather than downloading a pre-built image. Much better performance than my old HamPi setup, especially for GNU Radio applications. The audio timing issues are usually USB sound card related, not CPU.

I've had good luck with custom Python automation scripts for repeater control and DTMF functions on Pi hardware. For your antenna switching, make sure you're using proper isolation between the Pi GPIO and relay drivers - that's usually where the timing glitches come from, not the Pi itself.
