[Hamlib-developer] Pulling my hair out

[Michael M. <mi...@mu...>]

I am trying to use a Sky Watcher ATGTe mount as a rotator.  Using Satdump I
get dozens of rotator errors when tracking a satellite.  Here is an example:

[06:37:55 - 03/04/2026] (E) Error setting rotator position 38.449001
43.745998!

Here is my start command which is run through a batch file at startup:

start rotctld -m 2801 -r com7 -s 9600 -t 4533
--set-conf=min_az=0,max_az=360 -vvvvv

If I start rotctl in interactive mode and issue the following commands:

Rotator command: p
Azimuth: 30.00
Elevation: 30.00

Rotator command: P 40 40
Azimuth: Elevation:
Rotator command: p
Azimuth: 40.00
Elevation: 40.00

Only the rotator never moved.

When I issue this command from a command prompt the rotator moves
accurately:

rotctl -m 2801 -r com7 P 222.0 43.1

In any event I think the position errors are prevent accurate tracking.

Can you help me?
