I just checked my AZ values and on AMC 3 it has 3800 H 29125 sr dvb-s2 8psk fec 5/6 pilot 0 (or off) and 4080 H 29125 sr dvb-s2 8psk fec 5/6 pilot 0 (or off). My readings for 3800 are 73%/80% S/Q and for 4080 74%/82% S/Q. No signs of any pixelation but I have a 10' dish tweaked right and an ortho feed and 2 killer Norsat LNB's. I can't see 137W due to LOS issues with my neighbours 2 huge maple trees so I can't help ya with those values.
