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.

There are a lot of projects on this topic as well as packages and tools?if you google “?remote rig raspberry pi” for example here is one..

That's my problem. There are tons of complex projects like what you
reference. I want something exceedingly simple, but I am not smart
enough to write it myself.

All I want is a window with either a transmit click on/click off or
separate transmit and receive buttons for the client. Possibly a
connect/disconnect button. The server just needs TX audio, RX audio, and
PTT to the radio. No CAT, no controls, just a basic software equivalent
of an old style remote control used with commercial two-way radios using
the Internet instead of a phone line.

I want to do it with uSDX, can anyone recommend a method to connect uSDX to RPi; rem?ote desktop is easy with tools like these as well as with CLI connection such as SSH?
