Hi Larry,

Lots of excellent advice so far!  I'll throw in one more thing to check:

> just not working like I remember it being before the move.

You didn't mention it, but be sure you're tuning up and down a little
for SO-50 just in case the frequency settings in your PC software
aren't matching the satellite anymore.  I was having fits trying to
receive SO-50 for a while, turned out that for some reason I need to
program in my SatPC32 (doppler.sqf file) a downlink frequency 5 kHz
lower than published (even though there are reports of some stations
observing SO-50 with a downlink frequency 5 kHz higher than
published).   I just use multiple SO-50 entries in my software, one at
published frequency, one +5, one -5, and one -10, and choose whichever
one works best on a given pass.  Haven't noticed this with the other
birds, and this wont' explain your problems with VO-52 (assuming
youv'e calibrated for default uplink/downlink offset already of

Anyway, that was my experience, just wanted to share in case it helps!
