Jay, keep in touch on the Kenwood.
Will do Tom. I'm not sure when I'll get around to looking at it; as I've got at least one other project that has priority (and thanks to Larry I know where the issue is now); but I will crack 'er open and poke around. Sounds like a good reason to either fix my signal tracer completely; or modify it to work as an audio tracer and focus on fixing it's RF stuff at a later date.
