I have a Link Controller RLC 2a V 4.28 running two independent repeaters on port 1 and port 3. Port 1 can access several micros to turn on and off several functions not related to port 3. Port 3 can access only one micro to change its courtesy tone.
The problem is when either port is sent a DTMF command the other port momentarily keys its transmitter just after the command is entered. This is not a big problem but if anyone has run to this and has a solution I would appreciate an answer as to where to start.
