I have a Blonder Tongue Head end, programing all applicable trancoders to their associated transponders based on SAT feed. My current SAT feeds come from 110, 119 and wonderful 129. The transponder presenting me a huge headache is transponder 14s23 (Spot beam) for SAT 129, feeds local Detroit HD channels, or it is supposed to. I cannot get this bad boy to rock steady, it causes HD transcoder to loose their mind. I can, when i reset any receiver to a point dish see the Local Detroit HD channels, the minute I convert any box back to QAM, it doesnt see it at all? Any thoughts out there??
