We have one, just one, in the DFW Metroplex market ... evident from having
nopilot carrier (which is approx 309 kHz up from the bottom channel edge)
present
if I am given to understand it.
About 6 months back I surveyed with an RF spectrum analyzer all TV channelsin
the DFW market from near Dallas then verified which ones I could receivewith a
10 year old Sharp digital TV.

Tim's right on suggesting not to rule anything out. I have a big Yamaha
RX, 10-15 years old, that routes audio and video through it in several
formats. When I installed it, I choked cables to speakers and antennas
before turning it on. All those interconnect cables are possible
antennas for Pin One.
Another point -- in the world of consumer products, the word "digital"
is very much a marketing term. For example, digital antennas. :) In the
case of a TV, the only technically correct use of the word is that the
RF tuner and demodulator for digital signals and some logic to support
those signals, is built-in, rather than an exterior box. My 10-15 year
old Sony had such a tuner for first generation digital TV standards
built in.
A new digital TV Standard (NTSC 3.0 I think it's called) was introduced
maybe 5 years ago, and is being pretty widely adopted major markets. It
has many interesting capabilities, including the ability to transmit
pay-TV, in which the decoders are connected to the internet and make
extractions from our bank account. Current generation TV sets will have
a new generation tuner built in, and some are better than others. There
are also several outboard tuners that that feed audio/video inputs of
existing sets.
