I still disagree. Call it what you want, but unless you can provide specific pinpoint steps to resolve the issue, then the first place to start is always a good visual. And my vote is around the radio and multiplexer. If you want to get a schematic going on this thread and look at the possibilities, I'd be happy to provide more places to start. I, my friend, have been doing this a long time as well. I really do not know what issue you are having with a good visual. But apparently you have more intimate knowledge than do I.
