Hello. I am trying to monitor the Department of Denfense P-25 radio system for the sites in King County. I know I need to set it up as a P25 system in the scanner, but what I don't know is whether the system is explicit or implicit. I program my radio by hand so would like any support I can get. I once tried to program the system but never received ti. Is there something special that needs to be done to receive the control channels in the 380MHz band? Thanks.
