I’m not the most current blogger on the web, but in my mailbox this
morning was a link to this webpage from Broadcast Engineering: http://broadcastengineering.com/hdtv/fcc-stations-four-days-file-notice-cease-analog-service-0210/

Note that the byline is dated Feb 10,2009. Note that the text of the
article says "The FCC Feb. 5 released a public notice giving full-power
TV stations until Feb. 9…" So the deadline was the ninth and the
article was dated the tenth. Hope you made the deadline!
