I pose that question because on a t-band Motorola type II digital TRS in South Jersey there is currently a situation where lots of police depaartments have migrated to the TRS from their own conventional frequencies. Unfortunately what the county did was they kept sticking them on the same TGID so that there are like about 10 busy PDs on that TGID. My issue is I only want to listen to about 3 or 4 of them plus county dispatch. So the question is if I program the UIDs of the police units I dont want to hear and locked them out, but I did not program any of the UIDs of units I would care to hear as well as left the TGID unlocked would that work? I understand it would take up space on my radiobut I'm really trying to cut down on unneccessary traffic in this area, and even with 2 radios going its easy to miss stuff.
