I have a coolsat 4000 pro, sg2100, fortec 80cm dish. I can get all the other tp (11.800, 11.987, 12.116, 11.807). These all come in with signal b/w 70 - 82 and quality of 65 - 75. But whenever I try any channel on 11.720, it is constant freezing and broken audio, but the signal is 79 and quality is 63. The signal and quality seem to match the other TP's that I can get all the time and 11.720 never comes in. I've tried flexing the dish to improve quality but it seems to be tuned in as good as it gets. I live 60 miles north of montana out in the country.
What should I try to get the 11.720 TP?
