    KATU’s power reduction is, in principle, a 12+ dB reduction. But, due to the vagaries of propagation, antenna pattern, etc. it is only down between 6 and 7 dB at my house located half a mile west of Aloha High School.

    It’s a beautiful, almost textbook, signal with only a slight amount of tilt across the channel. Measured off air, KATU’s new signal is 3+ dB below the FCC’s spec for the amplitude of its intermodulation shoulders at the channel’s edge.

    One small correction to a previous post, KVDO-LD is licensed to Albany, transmitting from Peterson Butte.




    KKEI-CD RF36, Vir ch. 38 has been 25dB lower than its accustom power when I checked the last three nights. That is if its ERP was 8.6kW as rated, it’s down to about 30 Watts now. Being low more than a day or two probably means a bigger glitch than normal. Perhaps the Final amp is down and we are seeing the driver feed-through.



    KKEI-cd is up to full power again tonight.



    Media Bureau to Begin Accepting ATSC 3.0 License Applications

    The FCC announced May 23, 2019 that it will begin accepting applications from broadcasters to deploy the ATSC 3.0 (Next Generation Television) on May 28, 2019.

    The commission approved the standard in November 2017 but needed to revise a number of forms before it could begin accepting applications. Applications will be accepted from all licensed full power, Class A, LPTV and TV translator stations with the exception of licensed channel sharing stations.

    Unlike the traditional broadcast application process, the FCC has established a one-step streamlined licensing approach; for those broadcasters voluntarily transmitting an ATSC 3.0 signal from its facility or from another broadcaster (channel sharing), it only needs to file a modification of license application with the commission.

    It’s been noted the top 40 media markets will begin ATSC 3.0 broadcasting by the end of 2020.

    The only stations locally that are nearly ATSC 3.0 ready are.

    Watch TV owned: KORS-CD, KORK-CD, KKEI-CD and KOXO-CD
    HC2 Station Group owned: KOXI-CD



    In Phoenix, AZ, there’s a “lighthouse” 3.0 station that channel shares several of the Phoenix area stations. If memory serves, it includes the 3.0 signals of the ABC and Fox stations. They’ve worked out a channel share agreement so these stations can continue to run programs (including subchannels) in the 1.0 HDTV format.

    My guess is that KOXO and the other stations in the Portland group will do something similar, with the four stations running on one tower in 3.0 vis channel sharing, while the other three run in 1.0 via channel sharing on the other three towers. It’s worth noting that none of them have announced a formal startup date nor established Facebook or website pages that I’m aware of. RabbitEars currently shows at least two on air with four feeds all running YouToo on a test basis.
