[V8] Radio Noise

As far as I know everything is stock. There is no alternator whine. The load of the defroster actually helps the noise go away. Sometimes all I have to do is switch it on and off. FM works fine but they don't carry "Glenn Beck" or "Rush". I just thought it was strange that 2 of the 5 Audi's both do the same thing. They both also make a whining/hissing noise when I plug the phone charger in.
I will check for the choke on the power supply. (what's it look like?)
Thanks for the help.
P.S. My new Ross-Tech interface and software arrive tomorrow so hopefully I can get the 93 running again

As a former stereo installer, I can tell you that the V8 already has a pretty
good electrical system as far as noise is concerned. Do you still have the stock
>From the factory you should have:
noise suppression spark plugs/wires and dist. cap shield
capacitor on the alternator
choke on the radio power supply. (located in the pass. side relay tray)
This is all stuff that any good stereo shop should be able to add for you - but
you should already have it.
My guess is something is wrong with the antenna or cables or amps. Again, a good
stereo shop should be able to ID the noise source and do something about it.
(and if your AM stations carry the same crap as around here, that would explain
a lot too...)
You might also keep in mind that if you have alternator whine, that could be an
indicator that you have a bad diode in the alternator field.
This would get worse with a heavy load - like the rear defroster.
