Monitor both sides of full-duplex MPT1327 traffic #871

There's an MPT1327 network near me that uses full-duplex audio, i.e. two traffic channels come up during a call. It would be nice if sdrtrunk could be configured to bring up both channels so that both sides of the conversation can be heard.

Me too! 10Mhz apart here so might need to use separate Tuners for Base/Mobile frequencies. Also, the mobile side does not go through a repeater so some form of squelch would be great!

Hopefully the NBFM Squelch Feature in #36 will be of assistance here. We could set up all the Mobile frequencies as NBFM but that wouldn't be very elegant. Ideally we would be able to get something like the Base on the Left Channel and the Mobile (using a separate Channel Map?) on the Right Channel. Even separate instances of SDRTrunk with different channel maps could work but again the main blocker is the lack of squelch on an MPT1327 channel (as opposed to an NBFM channel).
