I'm currently leaning towards the theory that I have an incorrect frequency
entry someplace in the scanner, or a bad talkgroup code that's almost, but
not quite, right. The problem is I can't hear enough voice on the dropping
out signal to determine what it is.
It might be an image or intermod, as you mentioned as I have a cellphone
repeater site very close to the house...not even a quarter mile away.
So I have any number of possibilities. GRRR...
