Just installed a 90 cm Ku dish with a HH-90 positioner. Coax run is roughly 150’ of RG-6 Quadshield. Using an Edision OsMio 4K receiver. Titanium Satellite verified all parameters are set appropriately for my system (thanks to Brian Gohl).
All works well without the DISEqC in line. When I install the DISEqC switch I still get a good signal from both LNB’s but the Stab won’t move the he dish.

Any ideas???
