I've seen our local networks lose satellite signals occasionally, but the thing that got me, is that while I generally watch the local channels via an OTA ATSC tuner, we also subscribe to DirecTV's local channels. During strong rainstorms, I'll often get signal breakup on my OTA signal, and switch to the SD DirecTV signal. Interestingly, I'll often see the exact same artifacts show up on the DirecTV signal as I'm seeing on my OTA signal. Curious, I put my TV on side by side PIP, with DirecTV on the left, and OTA on the right. Since my DTV goes through a TIVO, there's a several second delay, so I'd watch the OTA, see a bunch of video artifacts, then turn and look at the DTV signal, and I'd see the exact same digital artifacts. I had previously seen the DTV feed go completely out when my OTA went out, so I had assumed that they were receiving the same OTA signal I was, and I also thought that the reception problems I would have during storms was all on my end, due to some big wet pine trees nearby that would cause reception problems, however when I see the DTV signal have exactly the same digital artifacts, ie blocks at the same time in the same place, I decided that the rain must me messing with the microwave link between the studio and the transmitter site, and the artifacts are being generated in the transmitter site receiver.
At least that's my guess. But anyway, it's nice to see that the professionals have some of the same reception problems that we do.
