I saw this on usenet and was wondering, what will the last day of analogue TV be like. I realize the February 2009 deadline is just the last date for stations to turn off their analogue signal and become all digital.
But I was thinking on the last day, you simply shut down the analogue transmitter and (if needed) crank up the digital transmitter.
Then I got to thinking this might not be possible for some station. It's my understanding (correct me if I'm wrong) that transmitters are built for a particular channel. And if one TV station is planning to use a channel that is currently in use by an analogue TV station (In the Chicago area both Chs 38 and 50 are currently in use and will be used for digital by station who now have their digital channels above Channel 51).
So I got to thinking it could be awhile before the channels get signed off and their digital signals up and running.
Anyway and thoughts about what this will be like. The only thing I will say is I think that after the dust settles we will see a shift in channel assignments like we did in some markets (like Ohio) in the 50s when the FCC misjudged the distance required between channels.
