[Icom] Mobile Noise Supression - Final Chapter

[Marsh Parker]

Doug,
The only thing else I can think of is a bad ground at the antenna 
connection point, but that would probably have shown up as a bad SWR.
Is the noise coming in through the antenna? Or the power line? Or both? 
Try disconnecting the antenna at the rig to test that, but of course 
don't transmit.
I assume the battery has a good direct connection to the frame as well 
as the other items you bonded.
Sorry to hear about the problem.  Good luck in solving it.  Don't give 
up yet!
