We are planning to make a single frequency network where all the transmitters must be sending the same audio at exactly the same time.
For this some timestamps (GPS source?) should be send together with the audio from svxlink to all TX sites and all audio should be delayed to give a total static value.
An example of this kind of network is here: http://www.coversity.nl
They use their own hardware and software, we would like to use SvxLink.
