In maintenance news, I put a new Air Filter on the truck ($21) and fixed a very annoying intermittent loss of signal on the coax to the Satellite.
Turns out the dang center conductor on the OEM cable end was 'just' too short to reliably make contact.
I've probably spent 16 hours debugging this since Feb.
The 'fix' was a needle nose to pull out the center conductor a bit, so that it fits down in the female part of the coax jack.
As say, very frustrating, but very simple fix. Argh.
