looks like stations that intend to keep their analog channel for digital have been pulling the switch early today, so as to give their engineers time to swap out antenna connections from the analog transmitter to the new digital transmitter set up on the analog TV channel. In NYC, channels 7, 11 and 13 are taking back their analog assignments and placing their digital signals on their old analog assignment. There's one case where a digital channel 33 is being handed off from one broadcaster channel 11 to another, channel 2. Wouldn't be surprised that that all that needed to be done for that was to change the baseband digital data stream feed from one station's studio to the other station's studio. And using the same transmitter and antenna. "Channel 11" becomes "channel 2". I suppose tonight, if you didn't rescan your box, and you punch in "11", you'll see "channel 2", and not channel 11.
Over at a New York City radio station listener forum, there are DTV reception reports:
