(this includes all DT9, DT54 and DT25 channels, along with all paid services)
We will be doing upgrade and maintenance work in our Master Control area during the overnight hours of late Thurs/early Fri 12/19. Work will begin shortly after midnight early Friday, which may last until 6am, though we hope to finish earlier.
This will result in all of our TV channels being off the air via all delivery methods. If you get your signal from a paid provider (cable, satellite, etc.) they will restore your signal once we’re back on the air. Many Over The Air (OTA) receivers will also re-acquire the signal on their own once the signals return, but some OTA viewers may need to do a rescan in order to reestablish a link.
(Affects several San Francisco TV & Radio stations, including KQED 9.1, 9.2 & 9.3)
During the week of August 25, Monday through Friday, between 9am and 4pm, several TV and radio stations will be switching to their Auxiliary antennas. This is being done so that the tower crew can perform routine maintenance on the regular TV and radio antennas at the top of the tower.
This may affect over the air reception for viewers at the outer reaches of the various station signals. Work should be concluded by late afternoon Friday 8/29. Those viewers who are affected may want to do a rescan once the work is completed.
(DT9.1, 9.2, 9.3)
The PSIP Info part of our Over the Air (OTA) signal for KQED DT9.1, 9.2, 9.3 dropped out of our overall signal early Wednesday 7/09. Once PSIP was restored most OTA receivers moved our signal back to the correct channel locations. However, for some viewers, it appears as if they have lost KQED 9. In most cases, the receiver has simply re-numbered us, and actually is playing our signals as Channel 30, which matches our real digital frequency.
Check your owner’s manual to see if you can manually delete/add single channels. If you can, first manually delete channel 9, wait 10-15 minutes, then manually add channel 30. Your receiver will first find the right frequency, read the restored PSIP info, realize we would rather be labeled as “9”, and drop us back in at 9.1, 9.2 & 9.3
If you cannot work with single channels, then doing a simple rescan should restore the PSIP info as well, and move us back to the expected spot in your line-up.
We are aware that all but one of our channels are not available via Comcast Cable currently. KQED Plus is still transmitting on Comcast Cable 10 and 710.
All of our Over the Air signals are transmitting without issue.
KQED engineers are in touch with Comcast, and working on restoring KQED HD, KQED Life, KQED World, KQED Kids, and V-Me to their respective Comcast channels.
(DT9.1, 9.2, 9.3)
KQED (and 3 other local Bay Area stations) will be doing full-load testing on new equipment at Sutro Tower early Tues 4/22 between 1am & 5am. If all goes as planned the KQED transmitter will go off twice during the early part of this period for between 15 and 30 seconds each time.
This should only affect KQED’s over the air signal and will not affect Comcast or Astound Cable carriage of KQED. Whether it affects DirecTV and/or DishTV will depend on whether they are taking our studio fiber feed or using our Sutro Over the Air signal as their source at the time of our tests.
(DT9.1, 9.2, 9.3)
KQED DT9’s Over the Air (OTA) signal from Sutro Tower will experience a few extremely brief outages on Tuesday 4/15 between 10am and 5pm (and possibly on Wed 4/16 if the work cannot be completed in 1 day). Each outage should be measurable in seconds (not minutes).
This work will not affect Comcast Cable and Astound Cable customers. Viewers and other paid providers who get their signals from our Sutro Tower OTA transmission should see their signals automatically restored after each brief outage, as these timings are well within the capacity of most tuners to remember the signal while it’s missing.

Some Comcast Basic Cable customers around the Bay Area have reported audio issues with KQED and KQED Plus, on channels 9 and 10. The problem is not related to KQED’s transmission but may be caused by the language setting on your Comcast remote control.
If your Comcast remote control is black, please check for a button labeled “Language” or “Lang” on your remote control. Instead of this button, your remote control may have a small white button near the bottom (possibly not labeled), between the “Volume” button on the lower left and the “Channel” button on the lower right. Press the “Language”, “Lang” or white button to determine if your language preference may have been reset to French or Spanish. If it has, press the button repeatedly until it is set back to English. This should restore your audio.
If the problem persists, or if your remote does not have either version of the button described above (ie., the Comcast silver remotes do not have this button), please contact Comcast for assistance with checking your language settings and/or turning off the SAP channel on your TV set.
Our KQET transmitter is now running at 85% power, which will be upgraded shortly. Most Over the Air viewers should be receiving the signal at this point, since many receivers would have automatically restored it once it returned to a near-normal level.
If you do not have a signal at this point, manually delete channel 25 from your receiver’s memory, then manually add channel 25 back in. If you cannot manually delete/add single channels in your system, then refer to the owner’s manual for your digital TV (or for the converter box hooked into your analog TV) for information about how to do a simple rescan for your system.
Some models don’t like to learn any new information, even when asked to do so during a simple rescan. If asking your TV/box to manually re-acquire the signal or simple rescans don’t seem to improve the situation, you can try a forced double rescan, which clears the memory, making your tuner as dumb as it was the first day you unboxed it, then ingests all new info.
1. unhook the antenna from the digital TV or converter box.
2. do the first rescan. the TV/box should report it found 0 channels
3. unplug the TV/box from the wall for 60-90 minutes, to be sure the box forgets everything it previously knew. some models have short-term back-up memory for power failures, so need more time to forget.
4. hook the antenna back into the TV/box, then plug the TV/box back into the wall.
5. if the TV/box doesn’t start rescanning on its own, tell it to rescan for the 2nd time.
Comcast will be doing work on Friday morning 12/20/13 (1:00AM-5:00AM) that will affect some local broadcasters. KQED channels will go off for approximately two minutes at some point during this window.
Planned maintenance work at Sutro Tower will likely lead to interruptions of KQED’s OTA signal in the overnight hours of early Thurs 11/14, beginning at 1am. Other stations transmitting from Sutro Tower may be affected as well.
Most receivers will recover the OTA signal once this work is completed. A few viewers may need to rescan to restore reception. This work will not affect viewers who receive their signal via cable or satellite services.
