Yort, I just retired from nearly 40 years working in broadcast TV.
Digital TV is a funny animal. Much of the time it plays well. Sometimes not. Before digital came along, the TV channels were separated by unused spectrum, guard bands. With digital the full channel is used, 6 megahertz. This presents a challenge to the broadcaster. That 6 megahertz must be maintained but it isn't perfect. Under the right conditions, there can be interferrance. The FCC added to the problem with the Channel Repack. This compressed TV broadcast into less sprectrum. Also, weather plays into this. An approaching weather system usually creates a temperature inversion. This can reflect distant signals on the same channel to your TV. Needless to say, this will cause issues. A temperature inversion can happen on a daily basis as well. This happens mostly in the morning after sunup. I have seen these issues cause audio problems with little impact on the video. This may not help but is came to mind.
Now, to collect the data on my problem.
