Channel 4 has been really spotty lately. They seem to be having a lot of equipment problems according to their staff. I sent an e-mail and they said that they were working on their antenna. I have been watching TV forever and I cannot recall any TV station going off the air at random for 3-4 hours a day and as of today it is going into their second week. Seems like there may be more going on than they are letting out. I hope they are OK because most of the shows we like are on that channel.
