As a novice to the world of FTA, I was wondering if I'd be better off setting up my motorized system (90cm Fortec Star dish and Fortec Mercury II receiver with a STAB HH90 motor) with USALS and then fine-tuning by phsically adjusting the dish with my hands or try messing around with the more complicated Diseq 1.2? Don't they both effectively produce the same results?
