I've got the same system (Charleston County Digital P25) in two different number selections ("banks"- I don't know if they're called that with Uniden Scanners. I know they were with my Radio Shack Pro-95.) For some reason, with the same frequencies entered in on both, one of the banks won't transmit ANY AUDIO AT ALL. The other one, however, works perfect. They both worked perfectly a few days ago but now only one does. None of the TGID's are on lockout mode. I don't know what happened. Anyone ever had this happen before or know what could have happened?
