In bank 1 of my Pro-96, I have the Quarry Hill/Eielson freqs in for the ALMR. My problem is that sometimes the radio will start picking up AST traffic that is not part of the ALMR. The screen shows that I am on 155.790 (AST Main), however the transmission sounds like it might be on the wrong freq. It is scratchy. I do not have the AST programmed in this bank and all the other banks are turned off. Anyone know why this is happening?
