Steve:

You have hit the nail on the head concerning my approach for now.  If this 
happened more often, I'd suspect the rig, but I really think it's something 
here somewhere.

And,I've got lots of coax jumpers to interchange.

The key is to be systematic about the whole thing, and be patient.

Having another power supply to try is also helpful.

Time will tell, I'm sure.
