Hi Ben,

Ah, that's what I was afraid of. Thanks so much for running the numbers. My setup here is pretty good, but I'm also in a bit of a hole, and am surrounded on most sides by live oak trees. The only clear shot at some sort of a horizon is to the west, and that just ain't gonna work. I don't get into the V/U birds very well below 5 or so degrees headed south east, and it's a lot worse on L or S. And, no, I don't own all the trees, so a chain saw is not going to solve everything :-).

One puzzle, though... If AO-51 is at a higher altitude than SO-50, therefore having a bigger footprint, why is the only mutual pass on SO-50? I'm guessing it's just how the passes (don't) line up at this particular time, right?

Thanks again,

Greg KO6TH

p.s. to Mark... Nice software, right operating system!

Does anyone know if either of the sats being used by K5D have a mutual window with CM98kx (that would be me)? I just realized that none of my software knows how to compute this, and all of the passes I've looked at don't appear to cover us both. If there is a pass, it seems like it would be vanishingly low on the south eastern horizon.

Greg:

I ran CM98 and FK68 through some software that Mark K6HX wrote a while back (and I begged him to send to me... Mark, have you released it yet?) and the results are not promising:

How good is your setup? ;)
