Funny how all those stations had to upgrade their transmitters to deal with
non-linearity that didn't much matter with analog, but would have prevented
them from transmitting digital, if all that changed was sending digital bits
on an analog carrier. Only transmitters that were less than 5-6 years old
didn't routinely have to be upgraded.
That, however, should not be used as any support for Bert's "full HDTV
transmitter" which is just as non-sensical as your response. Is there such
a thing as a semi-HDTV transmitter?

Could you please explain what a full HDTV transmitter is?
Last time I checked, transmission was still analog, and near as I can
tell, it always will be. The fact that that an analog carrier is now
being used to deliver bits instead of analog waveforms is ALL that
has changed. the FACT that bits can represent ANYTHING, is what
decouples the source content from the transmission channel. So yes,
any digital broadcaster will technically be cable of delivering HD
content in the future; but this does not mean that all content will
be delivered in HD quality.

There are plenty of AM music stations as well, especially in your
neighborhood. To be certain, there is a question of spectrum
availability. And there is a question of economics as well. The
reality is that AM radio is thriving because there is a huge
installed base of receivers and it is good enough to support the
applications for which it is being used.

The talker in this this market is on FM too. Obviously I consider
this to be an advantage, but it is the content that i am seeking, not
the radio band that carries the content I want.
The reality remains unchanged. In the world of audio there are many
quality levels. The reality that the overall level of quality has
improved over the decades does not detract from the reality that
applications will migrate to the quality level they need and can
support economically.

Again, this is an overly broad statement without any documentary support.
Please project the point in time when any TV station will be losing
revenues because they are not delivering all of their content in HD.
For that matter, please project when commercial stations will lose
money if they don't turn off their NTSC transmitters in favor of
their DTV transmitters.
As for the networks, HD is an emerging reality for SOME of their
content. All of the networks have become huge entertainment
conglomerates, with the primary business being content production,
not content distribution. As i indicated in the previous message,
most of this content has been acquired at what we consider to be HD
quality levels for several decades.
