I get my locals from 129 (SD locals). Sunday night, one local was pixellated, and the others were fine. Could that be due to different transponders? I typically lose 129 if there is any weather at all, but usually it is all or nothing.
...rather than a reception problem? That makes sense. My wife never buys that explanation
I did not realize there was another antenna component to the system.
We have seen some odd things on the OTA signal as well: We were recording a show (The Amazing Race) that had been preempted by football Sunday before last. We knew it might happen, so we had set up to record the following show (Cold Case, I think). The half hour or more of TAR was great - clear and crisp. The remainder of the show that was recorded as the following program was not watchable - pixellated and dropouts. I cannot believe the reception died in the space of a minute. We see that kind of thing all the time, and will check the same channel later the same night, and it will be fine....
