havent figured things out yet. new 1.2 dish. new pll lnb, new microhd receiver. couldn't receive al jazeera when i turned tv on today. receiver has been going 24/7, more or less. shut off receiver for a bit, and fired it up again. same result. no h, good v on 97w, 72w, and 125w. will try changing the lnb tomorrow. charlie
