:said by tschmidt :DTV coverage is often somewhat less then analog. Hopefully once stations get better real world experience with DTV transmission they will submit modification to FCC to increase coverage, by increasing Tx power (expensive) antenna modifications
I thought I remember seeing somewhere that once the analog stations are shut down, the digital transmitters could power up to full strength. During the transition there were only operating at a percentage of what they were capable of. I don't know if that is true or if that power up has happened for some stations already or not.
In our area - NYC - there's only one station that I know of not at full DTV power - channel 13.1 WNET (PBS). On the 12th once they shut off the analog tv, the power of the DTV ch 13.1 will be cranked up
