[amsat-bb] SatPC32 Yaesu rotor not registering 180 degree properly

Hi Christopher,

It sounds as though your interface unit (sitting between the COM port and
your rotator controller) is only set for 90 degree elevation, or, possibly,
just needs recalibrating.

I'd be looking there first.

Subject: [amsat-bb] SatPC32 Yaesu rotor not registering 180 degree properly


I am attempting to use SatPC32 12.8c on Windows 7 to control a Yaesu GS-232
rotor to track my university's cubesat. All connections have been doubled
checked for accuracy. In the setup, the 180 degrees max elevation is
selected, along with the correct setup for the com port, and the rotor
interface is set to Yaesu GS232.

For some reason, the software is only registering that the rotor has 90
degrees of elevation still. Meaning that when the rotor controller reads
180 degrees, the software reads 90 degrees. Similarly, when the controller
reads 45 degrees, the software reads 90. It seems that all built in software
settings have been explored and a solution for this problem cannot be found.
Any suggestions?
