Thanks to everyone for their input,
I decided to take the radio in and bench it
I came on OK, so the problem is in the car.
either power or extender cable. I don't know why I didn't do this before,
maybe because it's confusing here with much pounding and hammering,
As we are getting new roof, working on radio on the roadside as I can't park
in my drive way. MUCH CONFUSION!
