I have a dish 1000.4 dish and have been experiencing very low signal and loss of all channels except the locals. I live in Florence, SC I checked the pointing numbers from the receiver and they were AZ 237 EL 35 SK 130 the actual numbers on the dish were AZ 174 EL 50 SK 80 I checked an install manual I found on line and the numbers were the same as what was actually done on the dish. To make matters even more confusing I went to dish pointer.com and the numbers there were AZ 157.6 EL 45.7 SK -24.8degrees ( question how does skew of -24.8 translate to the skew numbers on the dish) my question is why the differences between the three sources and which should I use to fix the signal issues?
