Just heard all units are to go back to normal channels. The attempt to fix the radio system failed and it is still at "half capacity". Units are being requested to limit radio traffic as much as possible or the system "will go down again".
Somehow your settings got messed up, or you programmed it wrong. Try this
Go to Menu
Program System - Enter
Scroll to System - Enter
Scroll to Edit Sys Option - Enter
Scroll to Edit Fleet Map - Enter
Choose Custom - Enter
Press Zero until it's back to Edit Sys Option.
Press Scan, hopefully it's back to normal.
