[amsat-bb] W0LMD Sat Tracker Jr. hunting/deadband problem

Hi all

I have a W0LMD sat tracker jr. that I've connected to my PC for automation.
Right now, I'm using Nova to control the rotor and SatPC32 to control the
radio (I would like to use just SatPC32 for both, but I dont see an option
to set a max elevation since my elevation can't go above 60 degrees).

The problem is that every pass starts out fine, but as it gets going, the
azimuth rotor starts rocking and hunting. It literally jerks the antennas
back and forth until I turn off the G-5400. I have the rotor set up in Nova
using Easycomm (and tried Novacom), but the "Deadband" boxes are greyed

Would anyone have a alternative solution or be able to help me off list?
Thanks in advance!
