Mon 8/01: DT9 Over the Air PSIP outage (apx 8:30am-2:30pm)

August 1, 2016 · Filed Under KQED · Comments Off on Mon 8/01: DT9 Over the Air PSIP outage (apx 8:30am-2:30pm) 

RESOLVED: PSIP was restored at apx 2:30pm Monday. Our signal should be ID’g as 9-1, 9-2 & 9-3 again.

(DT9-1, 9-2 & 9-3)

BACKGROUND: the PSIP information line in our Over the Air signal stopped again this morning. So while we were still transmitting programming on our three channels, they were showing up as 30-1, 30-2, 30-3, rather than 9-1, 9-2, 9-3, until the signal was repaired again. Viewers can determine if this is a station issue by punching in channel “30”, and seeing if they find us there. However, the onscreen guide info will not be available until PSIP is restored, and the channel reverts to identifying itself as “9”.

Additional info for the curious: since the digital conversion several years ago, very few stations actually transmit on the old frequency that the channel number identified. The FCC didn’t want viewers to have to learn new numbers for all their local TV stations, so even tho TV stations now transmit on different frequencies from their analog days, a “Virtual ID” is sent as part of the PSIP info, which tricks your TV into labeling the new frequency with the old number. So, with our virtual ID currently not working, our signal is currently labeled with our Real Frequency (RF) number, which is 30.

And what does “PSIP” stand for? Program and System Information Protocol (the data line that includes the program guide info and the virtual ID for changing “30” into “9” as our channel number).

Mon 6/27: DT9 PSIP issue for Over the Air viewers

June 27, 2016 · Filed Under KQED · Comments Off on Mon 6/27: DT9 PSIP issue for Over the Air viewers 

RESOLVED: PSIP was restored at apx 2:50pm Monday. Our signal should be ID’g as 9.1, 9.2 & 9.3 again.

(DT9.1, 9.2 & 9.3)

Our Over the Air (OTA) signal for DT9 is still transmitting. However, we are aware that the PSIP information line in our OTA signal has stopped. Engineers are working to resolve the issue.

In the meantime, OTA viewers may be able to find the three channels at 30.1, 30.2 & 30.3 until the issue is fixed. However, the onscreen guide info will not be available until PSIP is restored, and the channel reverts to identifying itself as “9”.

Early Wed 5/04, beginning 12:30am

We will be shutting down our KQED DT9 Over the Air Sutro Tower (SF) transmission at apx. 12:30am early Wednesday May 4th, in order to install some new equipment. We expect to be back on the air between 4am-6am Wednesday morning.

Most receivers will automatically re-acquire the signal when it returns. A few viewers may need to do a rescan to recover all 3 channels.

KQED DT9.1 – 9.3, Sunday 9/20: Over the Air signal down

September 20, 2015 · Filed Under KQED · Comment 

UPDATE: KQED’s Sutro Tower signal was restored to full power shortly after 3pm on Monday. If your TV set has still not re-acquired the signal automatically, a rescan is probably in order.

UPDATE: Our over the air signal was restored at 50% power apx 4pm Sunday. This power level will restore the signal for most OTA viewers, but some at the outer edges of our normal reach may not yet be able to re-acquire the signal.

Repairs are continuing Monday. We do not yet know when we will be back to full power.

Sunday 9/20: As of apx 1:15pm this afternoon, KQED’s Over the Air signal from Sutro Tower for channels 9.1, 9.2 and 9.3 are currently down. Engineers are working on the problem.

Sutro Tower Annual Maintenance, week of 8/24 daytime

August 24, 2015 · Filed Under KQED · Comment 

(may affect Over the Air signal for KQED DT9.1, 9.2, 9.3)

The Sutro Tower team will be doing their annual tower check and maintenance work this week, meaning that all stations may be switching back and forth from their main antenna to their auxiliary antenna between 9am and 4pm. Work should conclude no later than Friday 8/28.

Most TVs will handle these changes without interruption, but some viewers may lose their signal. Some TVs may restore themselves when the signals return to stations’ main antennas each afternoon. If you still have no signal for one or more stations as of 5pm, a rescan may be in order.

Xfinity Cable subscribers will not be affected by this work.

KQED DT9s OTA: very brief outages Thurs 6/11/15

June 10, 2015 · Filed Under KQED · Comment 

(DT9.1, 9.2 and 9.3)

There will be 3 very brief outages (apx. 10 seconds each) of KQED’s Over The Air (OTA) DT9 signal Thurs 6/15, between 10am and 3pm. This is to accommodate preventative maintenance and inspections at Sutro Tower. Most TVs will recover easily each time the signal is restored, but a few viewers may need to do a rescan late afternoon, once the work is completed.

Comcast and other cable systems will not be affected in any manner.

KQED most channels, planned overnight maintenance: early Wed 1/14 midnight-3am

January 12, 2015 · Filed Under KQED, KQED Plus, KQET · Comment 

(includes all DT9, DT54 and DT25 channels, along with most paid signal providers)

We will be doing maintenance work in our Master Control area during the overnight hours of late Tues/early Wed 1/14. Work will begin shortly after midnight early Wednesday, and should be done in 2-3 hours, perhaps sooner.

This will result in all of our Over The Air (OTA) signals being down, which will also affect those paid signal providers who use OTA as their source. If you get your signal from a paid provider other than Comcast, 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.

Most Comcast channels will continue to transmit during the work. The exception will be KQED Plus (Comcast 10/710 most areas), which will go dark during the work, and be restored along with the OTA signals.

KQED all channels, planned overnight maintenance: early Fri 12/19 midnight-6am

December 16, 2014 · Filed Under KQED, KQED Plus, KQET · Comment 

(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.

Week of 8/25: Sutro Tower work (including KQED 9 Over the Air)

August 26, 2014 · Filed Under KQED · Comment 

(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.
