Im currently in Jones county Texas. Am learning sdr. I have sdr trunk working , and decoding some p25. Radio reference site says 158.850 is the freq being used. But when i put that in, it doesnt say control on trunk program. I have currently 1 rtl-v3 . And recieved the m6 rattlesnake antennas for high frequency. And will be ordering my second v3 dongle this week. I am picking up conversations but have yet to find the control channel. Any help will be greatly appreciated. I was able to use Abilene TX control channel and see it connect. But they are in next county. Was hoping to find Jones county control freq.
