Ok today I decided to check out the new mpeg transition channels. Well I get a 771 on all the new channels. I did a signal check on 99C sat and got all zeros. Once in a while a couple of xponders would show a signal of 12-15 signal strength, then go back to zeros. So I looks like I need to peak my dish. What sat should I use to tune my dish? Oh my 103b signals are in the 50'S and 60'S....
