If you haven't realized yet. WUXP MyTV 30 (rf 21) has been off the air since yesterday evening. It has tried to come back on the air but for a few seconds though. I have e-mailed the station and have gotten a response back. I have posted it below. It doesn't really tell me much, but at least they responded back.
Sorry for the inconvenience, we are having technical problems with our transmission tower and our Engineers are working on it.
If I get any more news, I will post it.
