I keep seeing all types of businesses (car dealerships service areas, health/doctor's offices, restaurants, other waiting room areas) with KWTV 9.2 on and the continuous loop of News 9 and their weather. (or maybe it's just channel 53 COX)

Seems like a no-brainer for KFOR and KOCO to do something like this on one of their sub-channels since it would cost next to nothing to operate. I remember when KFOR first when DTV and they had a radar loop on 4.2 and it went away after a few months or within a year or two.

Yes, I know you can view all of the local newscasts on demand on the websites and apps, but the simplicity or Over-The-Air and the ability to quickly get a headline update or weather update while in a forced waiting area is convenient instead of pulling out a smart device.

KWTV is the only locally owned station. And they locked up the market for the “local loop” with “News Now 53” on Cox over 20 years ago. Clearly defined and curated classic reruns provided by a national programmer who does everything for the local station in exchange for the local station selling 6 minutes of ads per hour is a win win.

I'm totally ignorant about over the air broadcasting since the advent of cable but l'm curious how do you have a channel 4.2, 9.2 or 47.5? How do TVs pick them up?

These days, even old people have been rejecting the high cost of Cable TV and are either getting on streaming TV, over the air TV or both. But the catch to over the air TV is you have to attach an antenna, like an old-fashioned rabbit ears to the appropriate input on the back of the TV for the TV's digital tuner and punch scan. It's kind of similar to how you may remember it as a kid, except you never had to punch scan.

As I recall long ago, my mother didn't like the fine bits of snow on the screen after we got our first color TV and decided we would have to do something about it by subscribing to Cable TV. As a result, no more tiny bits of confetti snow on any of the channels was cool. But fast forward by decades and today Cable TV has become far too expensive. And since around 2009, unlike snowy analog signals, digital signals are either there or they are not from being too weak. I think digital signals are better for reception, especially if you could never stand for any snow.

It was an industry standard agreed upon before any of the transmitters, receivers, or TVs were produced (with possible exception of old TV with add-on external receiver). Basically stations could pick to broadcast their station at a higher resolutions, put four stations at the resolution they were doing before the upgrade, or if willing to show lower resolution degrading quality for more channels (though if replaying pre digital content like 90s or earlier might be the full resolution it originally was). So on the common case of 4: station broadcasts out four channels on their old channel, like picture in picture with each channel in a corner. The TV just picks which one of those four to shows at full size by the sub number given and ignores the rest.

I think KOTV-6 CBS Tulsa is owned by the same company that owns KWTV-9. Like KWTV it doesn't have very many subchannels. 6.3 is a replay of KOTV Tulsa news like KWTV 9.2 is a replay of the KWTV OKC news.

KOTV's signal makes it into Stillwater better than the other Tulsa stations, which fairly often aren't even there.

A lot of guys will like it that the DEFY channel is now on KFOR 4.4 after exiting 52.5 several months ago for ION+. If you haven't been able to get DEFY channel on a couple of low powered OKC TV stations, then you can now on channel 4.4.

You mean ATSC 1.0. Because according to wiki, "ATSC 2.0 was a planned major new revision of the standard which would have been backward compatible with ATSC 1.0. The standard was to have allowed interactive and hybrid television technologies by connecting the TV with the Internet services and allowing interactive elements into the broadcast stream. Other features were to have included advanced video compression, audience measurement, targeted advertising, enhanced programming guides, video on demand services, and the ability to store information on new receivers, including Non-realtime (NRT) content.[15][16][17]

However, ATSC 2.0 was never actually launched, as it was essentially outdated before it could be launched. All of the changes that were a part of the ATSC 2.0 revision were adopted into ATSC 3.0."

Moving to a different informative topic, flat indoor antennas work out best if they are made to accept connections with RG-6 cable. That kind of cable cuts down on signal loss. I know, since using an antenna like that gets me all the high powered OKC stations, but it had to be mounted at ceiling level. That way it gets VHF 5 and 13 fine and steady. Most flat antennas, though, come with a thin built-in cable that can't be traded with RG-6 cable. Such antennas may work out if you don't live too far from the towers. Stillwater, especially in the valleys, can be difficult with bringing in all the high powered OKC TV stations with a steady signal when using an indoor antenna, amped or not.

The Antenna Man on YouTube is a great place to get elaborate info on indoor as well as outdoor antennas. He has tested a bunch of them.
I am TV shopping and saw the ATSC 3.0 and it looks like currently channel 9 is not using 3.0. I dont have a tv with 3.0 right now but looking at them. Thoughts on 3.0 and what stations are broadcasting at this time.

Channels 4, 5, 25, 34, and 43 are the only OKC stations broadcasting in ATSC 3.0. About all are only simulcasting their primary ATSC 1.0 channels and often video is upscaled to 1080p. However, Fox 25 is offering the T2 channel, so there is nothing but tennis on all the time.

ATSC 3.0 is supposed to give OTA stations the same capabilities and features as online streaming. But broadcasters are slow in adapting them. Lawsuits aren't helping. In a statement to the FCC, LG said the “challenging and uncertain patent landscape” around ATSC 3.0 forced it to halt support for the standard in upcoming models. The company was ordered to pay $1.68 million in a patent suit over ATSC 3.0 technology, which LG says would amount to a 125% increase in patent fees per TV sold with NextGen capability. So ATSC 3.0 is no longer in new LG sets. LG has appealed.

OKC ATSC 3.0 signals are stronger, so people in fringe signal areas might want to try getting a ATSC 3.0 tuner or TV with 3.0 for more stable reception. But avoid the HDHomerun Flex 4 tuner. It can't decode channels 4 and 5, due to DRM.

Consumer Reports did a recent article on ATSC 3.0. https://www.consumerreports.org/electronics/emerging-technology/nextgen-tv-atsc-3-what-to-know-a7427792466/#:~:text=Over-the-air%20TV%20broadcasts%20using%20the%20new%20ATSC%2 03.0%20standard?msockid=37449ae590d6637e03768e0791 bd6274

Heroes and Icons is now on 30.5, Movies! Is on 62.4 ( both stations are owned by MeTv), and Gameshow Central which is on 62.6
