A very strange incident this morning. BTW-I'm on an OTA antenna in LaFayette. In the early morning, I turn on the telly and listen to the news from the Indianapolis stations. To my surprise, this morning, ALL the Indy stations (on my multiple tv's) were BLANK. As in, no signal level, no RF, zero! The four LaFayette stations were at normal signal levels. So, I ruled out a problem with my RF distribution in the house. After a few minutes of scratching my head, I tried something. I had the tv do a scan for "new" digital channels to add. To my surprise, I got the Chicago tv stations! So, something in the ionosphere must be somewhat out of kilter. Has anybody else had this happen? I'm familiar with this happening on commercial/amateur radio frequencies (as in "skip" signals). But, I've never seen ALL tv channels from one area be blanked out like this. An interesting phenomenon, to be sure.
