Mesh Repeater

From SUWS-wiki

This is a draft of a Mesh Repeater Idea.

There could be a central transmitter to cover campus, with mesh nodes used around campus as just receivers, but coverage could then be filled in with mesh nodes around homes.

A central server would detect CTCSS, using this to trigger the transmitters, and would mix all CTCSS-present audio streams.

Mesh Nodes

Pi!

Option 1: Using RTL-SDRs

1st antenna -> rtl-sdr -> rtl_fm -> audio streaming to central server

audio from central server -> PWM TX -> 2nd antenna

Option 2: Using soundcards + Baofengs

baofeng -> soundcard -> audio streaming to central server

audio from central server -> soundcard -> baofeng
