Currently I use Gpredict which is a bit outdated software to control my Sarcnet rotator. I used to control Sarcnet rotator through Ham Radio Deluxe as a EasyCommII on COM_whatever was the number, but because my arrow antenna is roughly 10 meters away from my radio shack I found that such a long USB connection is very unstable. When I press PTT it gets crazy. Solution to resolve the problem was to remove long USB cable and replace with a short one connected to raspberry pi – I use Raspberry Pi Zero 2 in CLI mode just to run the hamlib Easycomm II server.

The problem I found was that I could not update correctly Kepler data for satellites, so some of them were not in the correct positions.
The solution is to add some extra lines to the config:
It resolves all problems with updating satellites Kepler data in Gredict.
