I think the broadcasters are just waiting for the right price for their
spectrum. Over the air broadcasting doesn't reach that many people any
more.
When the switch to digital occurred, all the stations around here
reduced
power. Most by 10 Db. Stations that used to have a good picture in
analog
mode now either aren't at all or reception is spotty. I changed to
satellite. In my view, the switch to digital wasn't progress.
Not true in the UK, though. During the digital switch-over digital
stations /increased/ power, and there are still a lot of people relying on
over-the-air TV (which is free), although many do pay monthly for a
satellite or cable service (to my mind, paying rather a lot). We had a
period for several years where digital and analogue co-existed, with the
digital running at lower power to avoid interference. In my view, it was
all quite well handled. The switch-over has yet to complete throughout
the UK.
I recently tried looking at the spectrum using my FUNcube dongle, and you
could start to see the individual carriers of the ODFM signal, but I may
have lost my single carrier 600MHz frequency references! We use the DVB-T
and DVB-T2 standards.

Sorry to hear that you can't get as good a signal any more. Our
broadcasting transmitters are co-located even for competing channels, so
one antenna pointing in one direction is all that is needed.
Digital has done nothing to improve program quality, of course, 90% of the
new channels are just dross, and transmitted in too low a bit rate!
Cheers,
David
