Today I rummaged through my junk box and pulled out:
- a screw-terminal type RJ-45 jack
- a 3.5mm stereo panel-mount socket
Sadly, the socket is too big to fit inside the RJ-45 jack housing, but I was able to cobble together a test using the jack as a break-out.
As it happens, there’s some repeater traffic that I’m hearing through the tablet beautifully. I set up Mumble to just transmit on VOX activity — this seems good enough. The signal out of the radio is quiet, so VOX works well enough for detecting the incoming signal with no false detection.
There’s a fraction-second delay, which is to be expected for a cobbled together Radio-over-IP solution such as this. It’ll be annoying if you happen to be next to the radio, but probably fine if you’re away from the radio (or you use a headset so you hear the delayed signal through the headset louder than the real-time signal out of the radio).
Things I need to look into from here:
- Computer transmit audio interface
- Computer PTT interface
- Mumble integration into the above
