No Impact in San Diego?

I don't think spectrum repack impacts any of the San Diego TV stations other than UCSD-TV, which elected to go dark with their LPTV (they are still available on cable).

Biggest unknown is the 600 MHz auction which is needed for the greedy wireless companies so they can deploy 5G. With ATSC 3.0 we probably wont need as much spectrum and perhaps stations can colocate their transmitter.

Looks like ATSC 3.0 is effectively final as of last month. I would not expect it to be deployed right away, but it probably gives the broadcasters the ability to test out the new technology. I don't think there will be another CECB program ala the analog to digital transition, but I do expect ATSC 3.0 tuners to come out some time this year, early next year for TV's that do not support it.

The repack effects start tomorrow. KLCS will go dark for San Diego when they move from channel 41 to co-locate with KCET on channel 28. Channel 28 is cochannel with XHJK making neither receivable.
Come next December, San Diego will also lose KOCE, KPXN, and probably KTLA, depending on what K35DG-D does (hopefully go off the air), all lost due to cochannel issues. The repack sucks.

I heard that k35dg is off the air.

EDIT: It has been off the air since 10/25/17 but you can watch UCTV content on cable, or internet enabled devices such as Roku players.

Apparently, this could mean that Televisa can move XETV to virtual 5 to align it with the national PSIP schema so that all channels match the channel numbers of their Mexico City counterparts. Or maybe not, as Televisa found out that KTLA would interfere with Virtual 5, so that plan got cancelled. Then again, it could happen.

Noticed that KPXN has completed their transition from channel 38 to channel 24. I also see that KNSD is broadcasting a test signal on channel 17 in preparation of their transition there from channel 40.

Oddly, I also see KGTV broadcasting their four subchannels both on channel 10 and channel 20 (low power). I don't know what the channel 20 is, but they should use different PSIP channel numbers. My TV does not like two 10.1, 10.2, 10.3, and 10.4 channels.

I observed that KNSD is now putting up a scrawl during some of their programming indicating they will be transitioning from CH 40 to CH 17 on March 17, 2019. More information is at nbc7.com/rescan.

I now see that KGTV broadcasting on channel 20 is KZSD-LP, a low power translator station for KGTV located on Mt. San Miguel (https://en.wikipedia.org/wiki/KZSD-LP).

Strange. It worked last week. Also, the expired domain message I get says:
sbe36.org expired on 11/11/2022 and is pending renewal or deletion
which is a few years in the future.

KPBS is now reporting they are moving from channel 30 to channel 19 on March 26, 2019 via a scrawl during their programming. This makes some sense, since KSWB needs to vacate channel 19 first (scheduled for March 14, 2019).

Do we know what time KSWB is moving on March 14? Are they also moving at 12:00pm? When I was in Green Bay Wi last summer, the stations moved around 1:00am.

I doubt ATSC 3.0 wide spread deployment for several years. ATSC 3.0 is not compatible with ATSC 3.0. So, they must transmit on an additional channel. With the 600 MHz auction, there are no channels available like there was for DTV deployment. Stations could pair up and use one stations channel to transmit ATSC 1.0 and the other stations channel to transmit ATSC 3.0. But that means they would have to run twice as many subchannels on each transmitter. Many stations already have several subchannels. ATSC 3.0 is not that much more efficient. The ATSC 1.0 transmitter would really have poor quality if they double the number of subchannels. The only solution I see is to wait until must people purchase new TV's capable of ATSC 3.0, and then switch from ATSC 1.0 to ATSC 3.0 with no simulcast. That brings up the chicken or the egg problem. I don't see the station owners being in a rush. They not only would have to update the transmitters, but also master control to handle 4K. There is no 4K programming from the networks. And OTA numbers are so much smaller than cable. Wouldn't they want to update cable first? I don't see cable companies in a rush to increase the bandwidth used by the local channels on the cable. Does the cable company reduce the number of channels so the locals can have 4K? I don't think there is a demand for 4K (cable or OTA). This is something the equipment manufactures came up with to increase sales. That was the whole reason for 3D. We see how that went.

I could see 1080p with HDR as a likely compromise for OTA. 4K is likely relegated for streaming and those who still wish to buy 4K BD's. However, there will likely be no CECB for ATSC 3.0 should there be another transition.

HDR would be nice. But it would still require more bandwidth (not as much as 4K), so would require upgrade of station infrastructure. Stations master control were not designed for HDR. Still require ATSC 3.0, which there is not spare channels to transmit for transition. In my opinion, it isn't going to happen for several years. I have yet to hear a person from a station promote ATSC 3.0. I have only heard TV station equipment and TV receiver manufactures promote it.

ATSC 3.0 is going to be a while for sure. 600 MHz transition also affects Wireless microphones as a lot of them use that frequency so now the manufacturers are making new equipment that works with lower frequencies.
