>>> Hello All,
>>>   Looking for a little help diagnosing a noise in my mobile and broadcast radio.  It's a "static" type noise that relates to my engine RPM.  It seems to be getting progressively worse.  I hear it when I open the squelch on my mobile and on some freqs of my FM broadcast radio.  My mobile radio is connected directly to the battery.  Today I changed the alternator hoping I would luck out.  I don't know how old it was and it wasn't going to be hard to replace so I went in that direction.  No joy.  The spark plugs aren't as easy to get to in this V-6 so I didn't do that first.  Perhaps spark plug wires next?
