My 996P2 and 325P2 only capture UID's about 80 % of the the time on two different 800 trunked systems. Im not talking about radios that pop up out of nowhere, it can be the same dispatch or same officer working all day who's radio may or may not show up. I live within a few miles of each system so reception is good. I also monitor a 700 trunked system that does better but skips the UID occasionally. Is this normal? Should I not expect the UID to be captured every time?
