Commercial tv transmitters arent just a matter of crystals they are
very expensive custom built to frequency, so they dont produce
interference on nearby channels ...........
plus every station needs at least a primary plus a secondary backup.
loss of operation for even a hour costs them bbig bucks
That would actually be an unusual situation because transmitters are
designed to operate on a specific channel. Plus purchasing new equipment
gave them a chance to buy much more reliable and power efficient equipment.
Uh, other than the <leases> recently auctioned off, the broadcasters
don't <own> the bandwidth to sell it. By definition and case law, the
airwaves are public property. Smells like urban legend to me.
it was all about the money the congress critters could get.

That your congress critters have been selling off for you
for the last 15 years, starting at channel 83. I can't find
the cite right now, but the final hdtv goal was all
transmitters would be in old ch 14 thru 51 allotment. Which
could work well with a lightweight, compact and efficient
UHF fan dipole antenna.
The original FCC hdtv reception studies (mid 90's) in
several major markets didn't work out as well as expected
with lower power transmitters. Either more power, or roof
top antennas would be needed. The Baltimore tests were
worst, too hilly of a terrain. A neighborhood could have
both a too strong of a signal and a too weak signal in the
same block. Some places the test equipment worked better
with no antenna connected, others, a window screen worked
better. Signal reflections were bad. The report is an
interesting read and in the fcc.gov archive.
Last numbers were 74% of the DTV stations on UHF (14-51),
24% on high VHF (7-13) and less than 2% on Low VHF(2-6).
With the virtual channel system, the actual frequency can be
changed as needed to improve coverage and reduce station
co-interference. channel 6-1 can always be channel 6-1 but
transmit anywhere between about 500MHz to 700MHz.
Smells like urban legend to me.
I've heard of proposals to eliminate OTA TV.
For me,that would be a major bummer;no cable and 48K dialup net service,and
TracFone prepaid cell service.
Also,what happens in power outages or natural disasters? At least now,I can
use a battery powered TV,generator,or an inverter/battery.
Cable and cellphones didn't work after Hurricane Charlie in 2004.
The FEDS would auction off the freed bandwidth...more money for them to
blow on socialist schemes.
Maybe you could get something on the internet. However, that
connection may be down.
When we had a storm 16 months ago, the electricity was off for 73
hours. The backup batteries on the cable node (I have cable internet)
lasted 4 hours. It was another 24 hours before they put a generator on
the cable node. I'm glad I don't have (cable company) Phone.
The National Association of Broadcasters sponsored it. I couldn't find
anything about it on their website, or anything about a bill before
Congress to reduce or eliminate OTA TV.
I think broadcasters want political pressure because HDTV may give them
a chance to expand. In recent years, most consumers, especially the
affluent ones, didn't get their TV OTA because they weren't satisfied
with picture quality. HDTV could increase the market and reduce
transmission costs. It may become profitable for new stations to come
on line, so broadcasters want plenty of bandwidth available.
I just dropped Comcast. $180.00 a month for the triple header
internet, phone and TV was just a little nuts.
I live 25 miles from Chicago. Went and purchased a Winegard HD7694P
VHF UHF TV Antenna
Built a MythTV media center.
Has 3 physical digial HD tuners for a total of 4 tuners(one is dual).
With multiplex broadcasts I can record even more(6-8 channels at a
time). Some TB hard drives and a subscription to Schedules Direct for
Not even looking back. Real Digital HD is NOT what you get from
1TB drive divided by approximately 1.6GB per ripped DVD leaves room
for about 600 movies. This does not even include the 1TB drive used
for everyday recording.
I'm not even using the tuners in the TV's
Alls i can tell you is that we are on the fringes of the KC metro area
broadcast area, and we had marginal analog service of 4 channels at
best. Now with a rudimentary antenna hooked to a new digital tv, i have
over 18 channels that are perfectly clear.
