The Radio Information Board

Thank you for those links and info- I'll read them over and see if it helps!

Does the radio just display a different random frequency because I'm out of range of the tower?

Hey everyone- first post here. I recently purchased a Bendix King EPH surplus radio from an agency that upgraded to UHF. I want to reprogram the radio for my current job, but I have two problems/questions: 1. No matter which channel I switch to, they all display 012.0710 on the display. I don't know...
