[amsat-bb] Satpc 32 question on tracking

Got tracking working with the FoxDelta ST USB version this past weekend. 
Doppler correction is working on the IC-9100.

When I ask it to track SO-50, it is supposed to go to 175.8 azimuth and 
1 elevation but instead it goes to 356 azimuth and 138 elevation.  I 
setup the FoxDelta for 180 elevation max and 450 azimuth max.

You would think there is an issue with the FoxDelta. But.... If I switch 
to PO-101, it moves exactly to its location perfectly. I switch back to 
SO-50 and it goes to a whacky az/el.

Have not turned off or touched either the Yaesu controller or FoxDelta, 
RS-44 coming over, tracked it perfectly.

Again not touching anything, just set it for AO-7. Was supposed to be AZ 
337.5 and EL 5.8 but rotor went to AZ 158 and EL 176. The ServerDX says 
target 159az/178el and actual 159az/178el.

Any suggestions? It has done this with several satellites. Even if I 
turn off the Yaesu controller and the FoxDelta and turn them back on, it 
goes to the whacky location for SO-50 and perfectly to PO-101.

On the Rotor page, there is a park location of 10 az and 180 el. 
Correction has zeroes in both az/el. Park automatically after pass is 
off. ServerDX shows target

Scratching my head on this one.
