Unexpected technical problems have been discovered at the KQEH transmitter site during planned maintenance overnight. KQED crews have identified the problem and are working to correct it as soon as possible.
Please check back to this blog for status updates.
Service to Comcast and other providers are uninterrupted.
(DT54.1 through DT54.5)
Early in the morning of April 22nd starting at 12 midnight KQEH will need to shut down for electrical maintenance and transmitter work. The Over the Air (OTA) signal should be back before 6am.
Comcast Cable customers, and customers of other paid providers using fiber feed out of our San Francisco Master Control area should not be affected by this work.
Most receivers should automatically recover the OTA signal when it is restored early Monday morning. However a few viewers may need to do a rescan in order to restore the signal.
Our DT54.1-5 Over The Air (OTA) transmissions from our tower on Monument Peak were interrupted for 3 hours this morning, from 5:20am to 8:20am. Service Providers using the DT54.1 signal for KQED Plus restored their carriage of the channel as soon as the signal returned.
Most tuners in digital TVs and/or converter boxes will automatically recover from an outage of that short a duration. However, a few OTA viewers may need to do a rescan in order to restore the DT54 signal.
KQET on Fremont Peak will be shut down for maintenance on Friday, March 15, from approximately 11am until 11:30am.
KQEH on Monument Peak will be shut down for maintenance Thursday, March 14, from approximately 11am until 11:30am.
Another TV station that shares the Monument Peak transmitter with KQEH (DT54.1 thru DT54.5) needs to perform maintenance on their equipment Monday, meaning that we will need to switch antennas and/or lower power for our OTA signal at various points, for the safety of the crew. Work is likely to begin around 11:30am, and should end by 5:30pm.
Most equipment should handle these changes without problem, but there is the possibility that a few (older) receivers may get confused. Should that happen, try manually deleting then re-acquiring the signal for DT54, or do a rescan to acquire a new lock on the signal after sunset, when everything should be back to normal.
Update: this problem was resolved late on the evening of Sat 2/23/13.
We are aware of the technical problems currently affecting KQED World and KQED Life both Over the Air (DT9.3 & DT54.3) and via Comcast Cable (channels 189 & 190). Engineers are working on the problem, but unfortunately we do not expect to be able to resolve it quickly. We apologize for any inconvenience.
We are aware of the lack of sound on current transmission of “Nature: Cold Warriors”. Engineers are working to solve the problem.
We are aware of the intermittent audio issues taking place on KQED World via Comcast Cable channel 190. We have a faulty audio card in the chain, and are awaiting its replacement, which should arrive soon. We apologize for any inconvenience.
KSBW is requesting we shut down KQET for tower work this Friday Morning, December 14, 2012. The outage is scheduled to begin at 12:30am.
12/14/12 Update: The work was not completed last night, so the tower is scheduled to be shut down again early 12/15.
