Thanks, all. Dave, your point on the BX24 s a good one: mine feeds a
PC which runs an Ocelot, and it was reporting nothing on the RF link.

The odd thing is that I opened ALL the breakers, and still found the
signal on two separate legs, with each only powered on individually.
Ialso pulled the coupler/repeater, that was not the guilty part.

Had I then connected my tester across one line and neutral, I would
have had a definitive observation instead of vaporized PCB traces.
