At least since last Monday (3 days ago) WCWN 45 [CW] (43.1) and the WRGB standard def sub on 43.3 ... have been coming up 'weak or no signal', except for a brief 2 second appearance at various intervals. They were there previously...and the antenna hasn't moved. I altered its direction to see if would make a difference. Nope.
I wrote an email to them, but they haven't responded.
