Does anybody know why I need to run a check switch every day so that I can get all channels? There are a quite a few channels that do not show up on the guide, but when you run the check switch, they are back. I have not taken an audit but one of them is 418 FSNMW and another is 170 NICK. I can not even get them by typing in the channel number until I run a check switch. Any ideas?
