In addition to the previously mentioned stuff:
Merit Street is in test mode on channel 306 and is scheduled to launch on April 2nd. In addition to paying TBN to takeover their .2 channels, Dr. Phil is also paying to takeover the .1 of WMBC/63 NYC, KVMD/31 LA,
WJYS/62 Chicago, KTXD/47 Dallas, KOFY/20 San Francisco, WGBP/66 Atlanta/Columbus and
WJAL/68 DC so his channel could get must carry rights on the cable systems in those major market DMAs.
EDIT: It's also now testing on the stream server
More March Madness and MLBEI prep, including moving WCBS, KCBS, TNT, TruTV and TBS to transponders with 5 HD channels.
686 DBACKS is back in test mode, nothing for PADRES or ROCKIES yet...
An INFO channel is now on 694-3 telling viewers they can catch the South Korean Padres/Dodgers games on ESPN.
375 Blossom is finally mapped to a TMSID with listings
Rockford's new CW affiliate WSLN/9 is now live, with an INFO channel replacing WIFR-L2/24
9754 GPPLAN (Gemini Protection Plan offer) is now live
Cleanup of some engineering records along with the SD Sig View records of the Denver and Boston SD channels
Greenville SC's SD locals (which will be going away in the near future) moved from TPN 4 to TPN 20, making TPN 4 the first 101 spotbeam transponder fully cleared of all channels. If they haven't already done so, they will likely be switching TPN 4 from D9S to D16 so they can start clearing some of the TID/PID conflicts for the markets that will be staying on 101.
