Andrew - If the Az and El motors are working, but the meter indication(s) are not, first check to make sure all the wires are properly attached. Also check to make sure all the cable connections are soldered properly inside the rotor. If the wiring visually checks out fine you probably have a dirty or defective feedback potentimeter.

Hi All,

Recently purchased a second-hand G-5500 for satellite work and just got it up and running this week. All seemed to test fine, but today I noticed that the elevation meter appears to have stopped working….I can manually raise and lower the antennas but the meter barely moves. No issue with the AZ meter, and most importantly, since I’m controlling it via PST-Rotator, it seems to still be working, i.e. steering / working without any problem in EL & AZ (via interface), so I’m still on the air.
I doubt I’ll be able to diagnose and/or fix the issue myself, but wondering if anyone had experience with this and had guidance. Would love to get it fixed.

Thanks,

Andrew – W3TI
