A quick demonstration of OP25 vs a Uniden BCD996T on a weak signal P25 Phase I LSM trunking system (Morris County, NJ).
Both radios feed off the same “Scantenna” antenna, multiplexed by a common CATV drop amplifier. Note the poor constellation in OP25. Using an RTL-SDR.org dongle with TXCO.
OP25 does a fair job of decoding while the 996T doesn’t even hear the control channel.
For years this system was unmonitorable due to terrain and distance. Not anymore!
