Gentlemen, just getting back into Satellite work - used to work AO-13 regularly with a pair of KLM twists, GASFET preamps, Yeasu 726R and Mirage amps plus a KCT tracker. Now trying to get my newly built LVB tracker to work with SAT32PC
I’ve read the post and response in the archives from 2018 concerning interfacing the LVB tracker to Sat32PC which was a big help (thank you!), but my issue is that while Sat32PC can now control the azimuth via GS-232 commands over a serial port, the tracker is ignoring elevation commands. I have calibrated the (90 degree) elevation rotor multiple times and stored to EPROM, but no joy to any of the GS-232 elevation commands, even when I issue them directly from a Putty ap via the com port. I can read back the calibration offset values and the rotor position, but none of the commands to the rotor to change elevation work. I know the elevation rotor interface is working because I can move the rotor with the LVB push buttons.
Although I just built this interface (from an AMSAT UK kit), the design is >15 years old and emails to the designer have gone unanswered. Any help would be greatly appreciated as I’m out of ideas.
Thanks and 73 Chris K4CKB
Did you find the AZ-only or AZ-EL checkboxes under Setup in ServerSDX?
