Every channel? or just 1 or 2?When a frequency comes in on my pro-97, their is a humming noise in the background? Anybody else have this issue? & what would cause this. I have tried base & mobile antennas, same iss occurs on both.
Headphones or speaker?All channels, even when codes put in on frequencies. Its a low hum in the background. I tried a dc power cord & ac adapter, same issue.
