i don't know what just happened but 4 DFW Local TV channels just went off the air on Dish Network. i was getting ready to watch an rerun of the Chappelle Show on 33 when suddenly boom TV goes pink all over the screen, changed the channel to 27 and saw the "Going off the air" footage they roll with has Star Spangled Banner playing in the background with some kinda war plane in the air. and it went to pink too, then flipped around the locals to find out that 21 and 49 are off the air too. these are the 4 channels info (calls, Affilations to networks, and owners, and analog ch #) 21- KTXA- CBS O&O, Independent 27- KDFI- FOX O&O, MyNetworkTV 33- KDAF- Tribune O&O, The CW 49- KSTR- Univision O&O, Telefutra as of 12:25 AM CST, they are not on the air on Dish Network. but WFAA ABC 8, KDFW Fox 4, KXAS NBC 5, KTVT CBS 11, PBS KERA 13, KUVN Univision 23, Telemundo KXTX 39, KTAQ 47 (which is now back on the air btw), KFWD 52, KLDT 55, AND KPXD Ion 68 are still on the air. i want to know if they are off the air on DirecTV also as well as on OTA. and if so, why i think it may have something to do with tower work to get it ready for the DTV switchover on Feb 17 (depending on whether or not the postponment bill get passed or not).
