I live just north of the PG Co. line in Howard Co. I cannot listen to the north side site. Won't lock on. Have good signal, but according to GRE, the radio can't discriminate between signals coming from two or more transmitters in different locations on the same control channel. They get to the radio at different times (milliseconds) and the radio can't handle it. I've tried all sorts of things to try to receive it with not much luck. The funny part is that when the radio is connected to my outdoor HDTV antenna pointing south, I can pickup the southside transmitter and talkgroups fairly well, but not the north. Driving around with the radio, I can get the north side very well when I'm near I-95 at Rt198. That should be no surprise since the transmitter is at Sweitzer Lane. I can receive in some parts of Laurel, but not all. Seems to work well in Bowie. Very frustrating.
