    What the article doesn't say is what they are increasing their power to?

    Like a Homer Simpson fool, I read the article. It mentioned, as an aside, that the equipment that is being used to serve up DTV is Next-Gen compliant. It isn't being used for ATSC 3.0.

    It also doesn't explain why a more powerful signal requires a "larger antenna".

    A preponderance of blog posts are clickbait and this one is no exception.

    As noted in the other thread, I moved a collection of non-ATSC 3.0 posts to this thread.

    300 kW. From 142 kW (on a higher channel).

    It's not a technical blog post, as far as I can tell, and so is vague since the presumed audience wouldn't understand it anyway. But their old antenna was a mid-power model running at 142 kW ERP. The new one is a high-power model at 300 kW ERP.

    Not sure why the OP thinks 300 kW is such a big deal. Sure, it's double the power they had before, but almost all the other major networks in St. Louis are 1000 kW, or close to it, so KETC is behind the curve in that regard.

    KMOV- 1000 kW
    KTVI- 1000 kW
    KSDK- 838 kW
    KPLR- 1000 kW
    KNLC- 900 kW
    KDNL- 1000 kW

    It also features a vertical component -- how common is that?

    In order to double the signal; at your location the station would have to quadruple their wattage, you may see an increase of about 1.4X in signal strength assuming all other factors stay the same.

    I said “doubled their power.” Which they did, no?

    If they also dropped down in RF frequency, the ability to cover more ground comes with that.

    I'm having considerable difficulty with the LMS as it seems to be feeding me zero-length PDFs when I try to review the license application files.

    FWIW WDCA in Washington DC will shutdown at noon on July 19. This is 4 days ahead of the deadline. Remember to rescan if you live in the area and use OTA.

    No word on what happens to all the subchannels.

    So Fox 5 “Plus” shares with WTTG going forward.

    I wonder if that relationship will continue for many years. Maybe ATSC 3 will offer other options, if it continues that long.

    All the subchannels will almost certainly move to WTTG, as happened in Chicago and Charlotte.

    PQ will suffer some. So they’ll be five channels instead of four?

    On edit: Wikipedia seems to say one subchannel must go.

    Actually, the article uses the phrase "one or more".

    Two 720p feeds coupled with five SD feeds doesn't strike me as practical. I'd be surprised if they didn't off at least two SD channels.

    Another undesirable option would be to convert MyN to SD.

    Wikipedia can be edited by anyone. In Charlotte and Chicago, no subchannels were dropped--and they have more in Charlotte than they do in DC.

    WDCA used the argument that a subchannel might have to go as partial justification for the last extension. Having said that I am not sure I believe it so we will see what happens at the witching hour.

    Woof!

    Two 720 and six SD. Must be some pretty awesome multiplexing hardware (or a really awful viewing experience).

    I get Charlotte OTA and trust me it is the latter. It is dreadful. I can’t understand how you as a company elect to participate in the auction knowing what the outcome is going to be and then complain about the problems it brings you. This just proves some care zero about OTA viewers and quality.

    I suspect that it is a combination of things:

    A. They want to push hard for ATSC 3.0; expect advertising campaigns "educating" the public that Next-Gen will restore the picture quality.
    B. They cut a fat hog selling their sister channel and they're going to swim in the proceeds for a while
    C. Because the lion's share of the population is willing to suffer it

    Good point, other than the PDX signals going N/S where there is less altitude. I live South of Astoria, along the coast and the days of getting PDX or SEA OTA directly are gone. Even it I detect a signal from SEA, like (14), never strong enough to lock. All I get now are the 5 live translators and sub channels from 2-6-8-10-12 PDX. 3.0 may make a difference. I used to get both PDX and SEA in analog, but not strong. Of course those were the VHF days.
