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

June 27, 2016 · Posted By Red Dana · 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”.

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 the virtual ID currently not working, our signal is currently labeled with the Real Frequency 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 6/13: RESOLVED – KQED Plus (KQEH) Transmitter Off the Air (DT54.1 through 54.5)

UPDATE: The signal was restored apx 5pm Monday. Most TVs will have recovered the signal on their own, but some viewers may need to do a rescan in order to re-acquire the signal.

Our KQEH transmitter in the San Jose area has suffered a failure, and is off the air. Repairs are underway, but we do not yet have an estimated time for restoration of the signal.

This affects over the air viewers of the DT54 signal. It does not affect Comcast/Xfinity service. Other paid signal providers should be able to receive the KQED Plus signal from our San Francisco transmission.

Mon 5/09/16: KQEH DT54 planned short outages

(DT54-1 through 54-5)
Monday 5/09

The DT54 Over the Air signal will need to switch from main to auxiliary levels at some point Monday (most likely early afternoon) for the safety of the crew working on another station’s equipment on the tower, then back to the main antenna late-afternoon when work is completed. The change should be for a couple/few hours at most, and will involve two short outages when the two switches between antennas take place.

Most receivers will automatically re-acquire the signal for each switch. A few viewers may need to do a rescan to recover all the stations which transmit from that tower.

This will not affect Comcast/Xfinity customers, or viewers of our DT9 or DT25 signals.

KQED DT9: planned overnight outage, Over the Air early 5/04

May 3, 2016 · Posted By Red Dana · Filed Under KQED · Comments Off on KQED DT9: planned overnight outage, Over the Air early 5/04 

(DT9-1, 9-2, and 9-3)
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.

4/17/16 – KQED Plus (DT54) Over the Air Issue: Virtual ID missing

April 18, 2016 · Posted By Red Dana · Filed Under KQED Plus · Comments Off on 4/17/16 – KQED Plus (DT54) Over the Air Issue: Virtual ID missing 

We are aware that many Over the Air (OTA) viewers are currently unable to tune in our channels on the usual DT54.1 through 54.5. This is due to a problem with our PSIP generator, which engineers hope to have repaired on Monday 4/18.

In the meantime, OTA viewers might be able to watch any of those 5 channels by punching in 50.1 through 50.5 temporarily.

Back when the big conversion from analog to digital broadcasting took place, the FCC decided that viewers should not need to memorize a new list of channel numbers, so even tho nearly every TV station in the country now broadcasts on a different frequency, each station includes a “virtual ID” code in its transmission that tricks TVs into renumbering the channels to their “old” designations. So, even tho KQED Plus is actually transmitted on frequency 50, the virtual ID normally is there to tell your TV to renumber it as 54.

Guide information will not be present until the full PSIP capabilities are restored, but many OTA viewers may be able to at least watch the programs in real time.

Tues 12/15: KQET DT25 signal restored

December 15, 2015 · Posted By Red Dana · Filed Under KQET · Comments Off on Tues 12/15: KQET DT25 signal restored 

(DT25.1, 25.2, 25.3)

The new part arrived this morning, was successfully installed, and our DT25 Over The Air signal restored apx 12:30pm. Due to the outage, some OTA viewers may need to do a rescan to re-acquire the DT25 signal. Paid provider services should have restored their signal by now as well.

Thanks for your patience, and for watching KQED (via KQET)!

Sun 12/13: KQET DT25 Over the Air signal down

December 13, 2015 · Posted By Red Dana · Filed Under KQET · Comments Off on Sun 12/13: KQET DT25 Over the Air signal down 

(DT25.1, 25.2, 25.3)
UPDATE Mon 12/14 4:50pm: Unfortunately, we are unable to repair our fried equipment, and will need to order/find a replacement. At this point, we do know the signal will definitely not return tonight, and do not yet have an estimated time re: when it will be back. Thanks for your patience and understanding while we work on repairs.
(This post will continue to update whenever I learn more. –Red)

UPDATE Mon 12/14 3pm: We’ve been able to get to the tower today, and have isolated the problem (a piece of fried equipment due to a power surge). At this point, we’re not sure if we’ll be able to patch up the existing equipment or need to order in a new piece, so we do not yet have an estimated time for the signal to be back on air.

ORIGINAL POST Sun 12/13: We are aware that our DT25 Over the Air signal is down in the Watsonville/Salinas/Monterey area, since about 10am Sunday morning. This affects both Over the Air viewers, and viewers of provider services that use that signal as their source for the region.

This outage will probably last at least a few days, as the severe weather at Fremont Peak caused mudslides and other obstacles, and we are currently unable to get to the transmitter to assess damage.

We will update this post as we learn more.

Comcast Cable/Xfinity customers are not affected by this outage.

Tues 9/29: Planned outage for KQET DT25 Over the Air signal

September 29, 2015 · Posted By Red Dana · Filed Under KQET · Comment 

(DT25.1, 25.2 & 25.3)

The Fremont Peak transmission tower will be undergoing one of its routine maintenance inspections Tuesday. We expect to shut down the KQET DT25 signal at approximately 2pm (along with other stations on the tower), and expect to return around 3pm.

Most TVs will automatically recover the signals after an outage of this short a duration. However, some OTA viewers may need to rescan once signals return. This work will also affect customers of satellite-model companies which get their signal Over the Air.

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

September 20, 2015 · Posted By Red Dana · 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.
