Simple Remote Radio

Michael WA7SKG

I have a need for a simple remote radio. All I need is two-way audio and PTT. No channel control or anything needed. Ideally, something via a web browser as a few of the users have limited computer skills. The user would need to be able to monitor the radio for several hours at a time. This would be used with both FM and HF radios, so the stream to the user may have noise floor audio all the time.

My thought was to use something like a Pi Zero for the purpose, the stream would have to be full duplex and use some I/O pins for the PTT.

The remote user would open a web page in a small window with a clickable on/off PTT button (on a timer for safety) and hot key option. That should allow use with a smartphone or computer.

This is a minimal budget project (aren't they all?) I don't need anything fancy like a RigPi.

Thanks for any ideas or suggestions.
