I just installed a 722 receiver and a 1002 dish for hd. I used to have a 311 receiver and on the signal strength it said dish has modified the signal. The signal strength meter on the 311 was down around forty or whatever. My question is. I have the hd working with about 65% strength. The picture seems good. Is the 722 supposed to be up around 100% or does the modified settings effect this receiver too?
