KLBK 13 in Lubbock was off both OTA and on Dish since sometime yesterday afternoon, came back up sometime this afternoon, still seeing some pixelation in their OTA picture.
They still had signal on the local cableco - Suddenlink - probably have a direct fiber line to them and I assume Dish picks them up OTA.
I tried several avenues of communicating with KLBK, but got absolutely no response (Twitter/Facebook, email) until 4:30 pm today the GM of the station responded to my email saying they had technical issues and were on a low power signal.
It must have been WAY low because I am about 5 miles from the transmitter and pull them in with a CM 4228 (old style) and neither of my Tivos nor either of my Hopper OTA tuners could get enough signal to assemble a picture.
As an after thought, they may have been totally down and are on low power now - thus the pixellation I still experience occasionally.
Signal strength on my Hopper Tuner is 75, whereas OTA strength has been right at 100 on this channel earlier.
