Huh? Is this the answer to the question about a color transmission being viewable on a B&W set?
Yes. The B&W signal is there. Color was added by fiddling with the base B&W signal.
The B&W set would only see B&W, of course.

Thanks for the explanation of Lighthouse. When I get my tower back up I want to try the pittsburg 3.0 channels with my HD Homerun tuner box. I will be using my big channel master movable antenna for the hd homerun. For now I only want to use the HD Homerun for pittsburg since its the only city that has 3.0 channels at present. You have to use the PC to do channel scans, (BAD Feature). I want to use other tuners to scan other antenna positions. Thinking of useing an A B switch. Using A for Homerun and B for all other antenna positions. Might even try using a 3/4 multi switch.What is supposed to happen (in theory) is as stations light up 3.0 transmitters, 1.0 transmissions all go to one station. That station has the big 4 on one frequency (the light house), and 3.0 on a separate frequency. All other stations put up 3.0 on their "normal" frequency. At some point (years down the road), the lighthouse goes dark and 3.0 is only thing left.
Current 3.0 transmissions (as I understand it) are on "test" frequencies and I don't know if there's more than one frequency per market.
Deployments - ATSC : NextGen TV
South Korea paved the road to ATSC 3.0, adopting its Ultra High-Definition (UHD) TV standard in 2016 and launching 4K ATSC 3.0 broadcasts in May 2017 that now reach more than 80% of the South Korean population. Jamaica has launched ATSC 3.0 services. India is exploring ATSC 3.0 for...www.atsc.org
I am sure they will have a tuner or receiver with ATSC 3.0. It will just be awhile before it out.

I'm calling it right now... Hopper 5!I am sure they will have a tuner or receiver with ATSC 3.0. It will just be awhile before it out.
IMHO, stick with the Samsung until the ATSC 3.0 dust settles.
722 is going to be phased out anyways so it wouldn’t matter.

You don't have to imagine that. Just hook up a 4K Joey to a Hopper Duo and try it. The Hopper Duo uses the exact same size hard drive as a 722k. (In fact, the hard drive in a Hopper Duo was likely recovered from an old 722k and refurbished to be reused in the Duo.) I have never actually tried this, of course. Still, since the Hopper Duo is capable of handling HEVC compression, I would imagine that it would store more than just 1 or 2 hours of 4K.
Why would anyone like that post?! 722 4EVER!!!!
That is a good question, even with my example of a 4K Joey connected to a Hopper Duo. I am assuming that someone here actually has tried this with a 4K Joey and a HWS. I am also assuming that the timer would need to be set from the Joey. In the case of the 722k, that was obviously a purely hypothetical scenario.
There are currently 14 markets broadcasting ATSC 3.0.
It is expected, and planned, for there to be 62 markets broadcasting by the middle of next year (~8 months). This isn't being slow-rolled by any means. Those 62 markets are expected to be able to reach approximately 75% of households in the US.
I will also add that ATSC 3.0 tuner chips are going to be built-in to many televisions next year.

Will that be one network per market? How many markets will have all of the Big Four broadcast in ATSC 3?
If I understand correctly, all of the Big Four (and maybe some other main local channels) will all share the one ATSC 3 frequency as subchannels, at least at first. I wonder if the primary station running the ATSC 3 broadcast tower has to be a station that is already affiliated with one of the networks. I know what I would like to see happen eventually in my area of Ohio is for independent low-power station WOHZ to strike a deal to simulcast all of the major network affiliates from Cleveland as subchannels. Right now, the only thing WOHZ broadcasts is a simulcast of one of the subchannels of its sister station, WMFD. I think the only reason WOHZ still exists is so that WMFD can force that subchannel onto the local cable system as a must-carry station, since a subchannel would not qualify for must-carry, but a primary station would. (The cable rules allow for low-power stations to have must-carry status, while the satellite rules do not.) So, in a hypothetical world where WOHZ is broadcasting in ATSC 3, they could continue to serve that same purpose (simulcasting WMFD's subchannel) with their primary channel, and still have enough bandwidth available to serve as a translator for all of the major networks. This would help fill-in an OTA coverage gap between Cleveland and Columbus, and help the Cleveland stations come closer to actually serving their entire DMA OTA. Or, if the Cleveland affiliates do not go for this deal, then maybe WOHZ could simulcast the network affiliates from Columbus, and possibly flip Richland County to the Columbus DMA instead. I would be quite happy with that scenario.
