It was picking up RFI and trashing the signal every time a mouse sneezed on it. This should be the end of the "hits" the signal was taking. I'm fortunate I have a skilled microwave waveguide plumber available, and that he was willing to stay up VERY late this morning.
The mystery remains, though, why the RFI suddenly worsened on the windy night this week. I suppose it is possible some clamp or ground or cable support or even antenna moved a little, and altered the RF conduction landscape outside, putting more RF inside the building.
My analyzer showed some occasional PCR errors afterward, about one every few minutes, but that appears to be happening before the STL, and it doesn't seem to be affecting PQ. I'll go looking for that Monday.
