Even worse is that in some markets, a station will be switching its DTV broadcasts to a channel that is currently in use for analog broadcasts by another station.
For example, in Detroit, Fox uses 2 for analog broadcasts, 58 for pre-transition digital, and will use 7 for post-transition digital. But ABC uses 7 for analog. So Fox can't switch unless ABC does so first.
