Chart of HDTV freqs?

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.
