Called support today. The very polite lady I spoke with, asked her supervisor several questions for me, although, I could not get transferred up the ladder. The fix is, they install ferrite beads, somewhere in the unit, to mask the RF noise. After explaining that it is not a boat wire issue (i.e. I can recreate the issue on my desk), I agreed to send it back to Alabama, this time, I also sent in my ICOM handheld VHF, as they have no radios there to try to recreate the issue. They should have it Wednesday, I'll post an update when I hear something.
Greg, if you're still around, can you add any insight? Or talk to the techs and see what's happening?
