oh and the dummy channels are set to NBFM but i was reading another post on here and it said to use p25 to set dummy channels i'll add a pic about that.
While back I was missing calls (tuner unavailable) with the Airspy mini because of the span of the freqs (2 sites, different systems) and where the cc's were. My one dummy is NBFM and it seems to work as I not longer get tuner unavailable. I also do not listen to my Sdrtrunk at all. Every talkgroups "Listen" option is set to off. I record many select talkgroups and have Trunking Recorder importing all the calls from both SDRtrunk and Unitrunker. I do selective playback thru TR's web interface.
