[amsat-bb] Satpc 32 question on tracking

[Stefan Wagener]

It's perfectly fine

...."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."....

337 AZ -180 is 157 (158 actual on your rotor)
5.8 E -180 is +_174 (176 actual on your rotor)
