This is something that is going to be happening over the next few days in many locations. The reason is the DTV switch over. The OTA signals that E* is picking up will switch to a different digital channel OTA. We will be doing this tomorrow night and moving from ch 13 to ch 9 so all will have to rescan. What has been happening recently has been possible testing the new transmitters or maybe weather related. In fact I just spoke with the uplink to let them know the time that we will be shutting down the old transmitter and powering back up with the new full power transmitter.
The reason the locals went out yesterday is because of the severe storms in the area of Mt. Jackson, Va. Do you lose signal during heavy rain in your local area? Imagine trying to shoot a signal through 40 to 60 thousand feet of water and ice to a target 22,500 miles away. Storms in this area of Virginia have been more intense than normal recently. I am guessing that the reason we see the slate saying locals will return shortly is because the main uplink center senses the loss of signal and transmits a temporary signal to replace the locals until the storm clears.
Wondering why E* picked this area of Virginia? My guess is (another one) that it is close to a national radio quiet zone for the best possible signal reliability National Radio Quiet Zone .
I hope E* has their s**t together before the switch on Friday.
