Most upper VHF and UHF DTV station allocations are for about the same PEAK
power for DTV as for NTSC, if they are on the same channel. The ratings
systems are different: NTSC is for sync peak, ATSC is for average envelope power.

Not so for lower VHF ... these were allocated lower power, and that was too low.
If they were the same power as high VHF they would work much better.
In fact, channels 4 and 5 might give excellent results. 2 and 3 suffer much worse
from impulse noise than even 4. 6 has the adjacent FM problem.

There is an NTSC station on channel 22 or 23 in the San Jose, California area. A friend of mine found it after we both put up UHF antennas pointed that way to receive an NTSC amateur television station on 427.25 MHz.

And not to be a bummer on the "DTV sucks train" but over the last 4 months we got 2 new movie channels on DTV Subs here.... Movies a 20th century fox movie channel. And also a new one on NBC I think its called Cozi I can't recall what movie company they are with. Plus AntennaTV and ThisTV I would happily trade all regular network channels for AntennaTV and ThisTV! We also have all news channels added, and I mean real global news like Aljazeera, Arriang, from S korea, NHK world from Japan. and a few new city cultural channels.... And the Nature Shows on PBS now look A M A Z I N G ! ! ! We didn't get pbs analog that well.... And the stations on the upper VHF band come in best, although they are slightly reduced in power.

As for analog, my parents live rabbit ears distance from the transmitters, and analog always looked great there, CBS up here analog use to be clear as digital is now, so when you get it the quality is the same, except now any light switch, motor, anything causes a bunch-a-blocks on the screen, or a more common guaranteed sound drop out.

Now everyone that owns a portable TV from the pre digital age is now worthless... You can't depend on a digital signal when a hurricane comes and knocks out the power.. Digital signal comes in all choppy and blocky when the conditions are either windy or cloudy.. I thought technology gets better...

Oh. You did not phrase it that way initially....It is things like this which give me the motivation to proof read all my posts.

Cuba was still using NTSC as of two weeks ago. Channels 2-5 were making it into the D.C. area via Es...

I did a quick check yesterday with my outdoor antenna. Not a thing, unless you count the slightly different kind of snow on good old channel 37.

I did discover that the filters on my cable connection are kind of cheap, and one channel is almost watchable.

204MHz - 210MHz analog NTSC is active here (VHF 12). I beam movies and experimentation through its small coverage area.
ATSC is good when it is capturable

I thought I'd revive this thread since I just discovered that there is a OTA analog station operating on Ch. 8 in or near Madison, WI. There had been a LPTV station operating on channel 8 a few years ago which then abruptly went off the air. Back then, it played still images of nature scenes, set to "new age" music. I was surprised to see it back, now playing old westerns. It looks like they're playing bad VHS tapes, complete with break up and tracking errors. Here are a couple of screen shots from my DuMont RA-113. The lousy resolution is the transmitted signal, not my DuMont



Gotta wonder what their business model is. I've never seen any advertising...

Oops! I didn't realize that this thread was originally started in the "vintage color tv" forum!

Perhaps it is an illegal LP broadcast.
