It has been reported at other sites that LPB's signal, since at least before this last weekend, is wonky. I am seeing the same thing on my 75e, as well as tracking the same fluctuation at

Besides the signal being, in general, lower than several weeks ago, it is also getting a daytime/nighttime fluctuation (could be their uplink dish needs a re-point, among other things!). Since I am using a 75e, which prior to this has worked very well for LPB, and the fact that VE2FCZ is near the northern extent of the same EIRP footprint as I am, would be why some of us see the fluctuation greater than others (in better EIRP footprints), to the point of complete signal loss.
VE2FCZ, you might also want to do a check (at night, obviously) to see if you can add a few points to the signal quality with a minor re-point. Could make a bit of a difference.
