.... and some stations will be transmitting DTV on a third channel (not the
present analog nor the present DTV channel)

I have also found that a number of stations have applied for changes (so far
they seem to be ERP changes) to what is contained in the eighth FCC report
of March 2008. One needs to go to the FCC site and enter call sign of each
station to find the present information.

A surprise to me is that the coverage contour for analog TV is 64 dBu and
for DTV is 41 dBu - a difference of 23 db. However, the reductions of ERP
do not seem to be that large. Stations that are now a bit weak may be
unusable after Feb. 2009.

What is happening is that many TV stations have been assigned a
channel on which to broadcast their new DTV signal prior to Feb. 17,
2009 while at the same time remain broadcasting their NTSC video on
their original channel. The chart shows these two channel designations
in the first two channel columns, and in the last column it shows what
channel the TV station will end up on when Feb. 17 comes around. As
indicated, some stations will be moving their DTV broadcast from the
temporary channel assignment back to their original NTSC channel
assignment, and some stations will remain broadcasting the DTV signal
on the temporary channel, which becomes their new permanent channel.
