I dont know but results on the screen dont lie. The NBC mux (11760) as example was at 67 on the Sadoun dual, 0 on this one and 70 on the SatelliteAV PLL
In fact on 103W with the off skew (set at 0 instead of what it should be) resulted nothing on the H side with this LNB. The Sadoun dual resulted with 4 transponders
My Avenger PLL on my GeoSatPro 90cm dish gets 11760 fine (in clear weather) with the skew set at normal on my motorized system. No trace of the other S2 transponders though. Must be a footprint thing.
