Well that's interesting. I wonder if that info can also help me out.
My new non-Alfa (with initials that sound like "TVR") has the same
problem with AM reception my 164Q had - no AM reception when the engine
is running. When I shut it off, it's great. Of course that means no AM
radio while I'm driving, which is what I like to listen to.
On my 164, I never found out the culprit (but admittedly I had no clue
even what to look for). I was surprised to find a similar Sony radio in
my "new" car, and have the same problem. There's clearly some
interference from something in the car. I will have to look on my
alternator for one of these devices.
Interestingly, it doesn't affect FM reception, and didn't on the 164,
either. I thought it was likely there was a bad ground somewhere, which
I guess is still possible on the TVR (actually more likely, I guess,
since there are fewer places to hook a ground, with the tube frame) but
really it seems unlikely it's a ground problem.
I'll take a look at my car.

ah yes - this explains the whine i also hear, from the fusebox (or
speedo?) area. no noise thru the speakers, cuz there's no radio in my
car! ;~)
thanks,
