I too also had problems getting S2 when i first put up my 6 ft setup.I dont if this is the case with the larger dishes but you need to be aimed just about exactly on the center of the satellite you want to get s2 from.I first thought i had the dish set up just about perfect!Was getting great c and ku quality on all sats that i could get but then realized i wasnt getting any S2.My first s2 lock finnally came in when i saw a small blimp of Q activeity on the PBS s2 TP.Went outside to the bottom of dish and slightly tuged and pushed on the dish and My Q jumped from around 7 to 60.So for me it was a very slight adjustment that was needed on the dish elevation.
36" motorized dish on garage roof and 6' sadoun dish! w/ DMX741, VBox powermax ver10,AZbox Ultra Hd using the 6 footer and GEOSATpro DRS200c+solomend running the .90cm ku dish. Neusat 9000 at backup.
