To unlink the currently linked module, call DMR ID 4000. To connect to module
A, call DMR ID 4001, for module B call DMR ID 4002 and so on.
Example
If you have TG969 linked either dynamically or statically, then the server will
forward group calls (coming from other stations (repeaters, hotspots, gateways))
going to DMR ID 969 to your openSPOT4. Your openSPOT4 will transmit it on
RF and your radio will receive it. Your radio will open the squelch if:
The TX contact of the currently active channel is set to TG969, or
You have an RX group list with TG969 in it and this RX group list is assigned
to the currently active channel.
