Our KQET transmitter on Fremont Peak, northeast of Monterey, will be off air for apx 25-30 minutes late Thursday morning, for maintenance. This will affect over the air channels DT25.1 through DT25.3.
Most receivers should reacquire the signal automatically after an outage of such short duration, but a few viewers may need to manually re-add the channel or do a rescan to restore it.
UPDATE: We believe we have the faulty part replaced, and the KQET DT25 signal fully restored as of early Monday afternoon. Thanks again for your patience.
Original Post:4/23: KQET DT25 off air intermittently
Due to a mechanical problem, the KQET DT25 transmitter has been cycling on and off air intermittently, beginning Saturday 4/21. This affects predomininantly Over the Air (OTA) viewers in the 831 area, although a few paid service providers may be using that OTA signal as well. We are working on repairs, but a final fix time is not yet known. We thank you for your patience.
We will be shutting down the KQET (DT25) transmitter on Fremont Peak on Tuesday, April 10th, from about 11am to 11:30am, for planned maintenance work.
We will also be doing maintenance for KQED Plus (KQEH DT54 transmitter on Monument Peak) on Thursday, April 12th, also around 11am to 11:30am.
Comcast Cable customers will not be affected by these outages. Most Over the Air (OTA) TV tuners will restore the signals automatically at the end of an outage this short, but a few OTA viewers may need to manually re-add the channel.
As of 1:45pm Tuesday 1/24, we believe the KQET digitization issues affecting Channel 25’s signal delivery to viewers in the 831 area via most paid service providers have been solved. Other carriers are confirming a good signal. (Over The Air viewers and Comcast Cable customers were not affected by the problem.)
The storm and high winds took our KQET transmitter on Fremont Peak Off the Air a couple times Saturday, and our digitization problem has returned.
What is perplexing is that Over The Air (OTA) viewers are reporting a solid signal, and are not having the pixelation and audio problems that other viewers in the 831 area are experiencing. We are working with the manufacturers of our equipment to troubleshoot our system, trying to find the source of the signal corruption, and where in the signal path it is entering.
We apologize for the inconvenience, and will update this post when we have any further news.
Comcast Cable customers are also not affected by this issue.
Update Thurs 1/05: work on KQED Plus’ DT54 transmitter is complete, and signal has been restored.
Update Fri 12/30: work on KQET’s DT25 transmitter is complete, and signal has been restored.
Scheduled maintenance will take place on our DT25 transmitter on Fremont Peak Friday 12/30. The transmitter will be turned off sometime between 10am and 11am, and likely be down 30-40 minutes.
The same maintenance will take place on our DT54 transmitter on Monument Peak Thursday 1/05, with the transmitter being turned off sometime between 1pm and 2pm.
The expected duration is short enough that most Over The Air receivers will automatically restore the signal once it returns, but in a few cases viewers may need to manually re-add the channel, or do a rescan. Comcast Cable subscribers will not be affected by either outage. Other paid service providers will restore their signals when the transmitter is turned back on.
This post will be updated each day once the signal returns.
Final Update Fri 12/02 3pm: The receive Dish for KQET on Fremont Peak has been restabilized, and the signal is now looking very good.
Update 5:45pm: KQET’s signal is restored, but with occasional dropouts. Winds are still very strong on Fremont Peak, so final tweaking of the re-braced dish may be delayed.
Update 2:20pm: KQET is expected to be back on the air by this evening.
Update 11am: Repair crews are expected at Fremont Peak around noon.
Our KQET transmitter tower on Fremont Peak (northeast of Monterey) is off the air. Very high winds have been reported for Fremont Peak, and the receive dish side of the signal path is loose and blowing in the wind.
When more info becomes available about the schedule for repair this post will be updated.
KQED Television and KQED Radio will be participating in the nationwide EAS test at 11am, which will last between 30 and 60 seconds. Normal programming will resume immediately after the test.
Weather permitting, we will be performing maintenance on our KQET transmitter tower on Fremont Peak (northeast of Monterey) Thursday 9/22 afternoon. We anticipate turning the power off at apx 1pm, and it should be restored by apx 1:30pm, gremlins permitting.
Comcast Cable customers should see no interruption in service. Other Cable, satellite, etc., service providers, may experience a reception interruption, depending on the source of their signal. Over The Air (OTA) viewers will definitely experience an interruption while the transmitter is off.
Most digital sets and converter boxes will also auto-restore the signal when it returns after so short an interruption, but a few OTA viewers may need to rescan if the duration of the outage becomes “too long” for their particular tuner.
KQED-DT9 (San Francisco)
Fiber feeds to Comcast Cable, Astound Cable and AT&T U-verse normal. Over-the-Air (OTA) transmissions normal, operating at 98-100% power. 100% power = 710 kW.
KQED Plus-DT54 (San Jose)
Fiber feeds to Comcast Cable, DirecTV and Dish Network normal. OTA transmissions normal, operating at 98-100% power. 100% power = 290 kW.
Fiber feeds to Comcast Cable normal. OTA transmissions normal, operating at 98-100% power. 100% power = 81 kW.
Two technical issues not related to transmitters:
The programming schedule for KQED v-me (Comcast 191/621, DT54.5, DT25.3) is currently 3 hours earlier than “normal”, as we are passing the satellite feed straight through, rather than delaying it for 3 hours. The delay box is out for repairs. We expect to stay on this “early” schedule for at least another 7-10 days, possibly longer.
The Over the Air DT54.# onscreen guide for all our DT54 channels is currently 1 hour off. It is also occasionally not reading information for its various channels, and instead posting a generic “DTV Program” message. A piece of equipment for this function is also out for repair. We anticipate this problem lasting through most of July, possibly longer.
Updates on both issues will be posted here as new information becomes available.
