I mounted a 1000.4 ay my cottage and I can only pick up 72, I can not pick up 61.5. I initially locked onto 82 (i think) and saved the switch settings. I then realized it was the wrong sat so I retuned the dish for 72.7 and got about 60 on the signal strength meter. When I run a switch test the only signal I get is 72. the others switchs (2-4) are good but no signal. I have a clear view but no luck.. can anyone help?
