I know this is a difficult signal to receive in any case because it is 16APSK and 4:2:2, so not all equipment can receive it, but I'm asking because it has always been fairly reliable and we can't get a good OTA signal on CBS. But last night and tonight there has been no signal there at different times. Earlier today and right now I can receive it but a little while ago I couldn't, so it seem to be an intermittent thing. I would just like to know if anyone else is experiencing that, or if I should be looking at possible hardware issues.
