To start with, I'm curious about two display(s) I see that seem to indicate a "hole" in coverage to the north. I just re-started so I'll have to let them fill in again to describe which are puzzling. I believe that they are "z,e", z,a" and z,d". When I first put an antenna to an old thunderbolt earlier this fall, I assumed my antenna was in a bad location, shielded by trees, house, etc. And it was, somewhat. So I moved it about 30' to the NE, further out of the shadow of trees, and saw the same results. So, installed a second antenna (just because), and again see the same results. the best explanation I can come up with is that the constellations don't cover "way up north", but I don't think that's the case. I may be mistaken, but I think the constellations cover the entire globe.
I've attached an earlier pic of what I'm referring to. I've recently re-started LH, so it will be a while before all the data is filled in again. I'll post screen shots and we can discuss it further then, if desired.
None of this is all that important, but I am quite curious about what I'm observing.
Anyway, thanks for any explanations.
edit - I've added another pic, this one goes along with the earlier one, further arousing my curiosity.
