  Public Press Release:

  Following loss of air conditioning at its mountaintop
transmission site, the KEYT-TV [Santa Barbara] transmitter
suffered a catastrophic breakdown Friday at about noon.  The
transmitter crash caused the over-the-air signal to vanish.
Viewers using an antenna are not able to receive the KEYT-TV
signal on their digital televisions.  Ventura County cable
viewers have also lost KEYT until repairs are completed.

  Cable and Satellite viewers in Santa Barbara and San
Luis Obispo counties are not affected.  Viewers in most of
the City of Santa Barbara may tune to Channel 17 to watch
KEYT over-the-air.

  KEYT engineers are working closely with equipment
vendors to get the station back on-the-air as soon as possible.
Please direct any questions to Chief Engineer Dave Williams at
(805) 882-3928 or by writing to d.williams (at)

  KEYT [Virtual Channel 3, RF Channel 27] uses a Harris
Diamond CD digital transmitter with a single exciter and driver.
The driver failed and diagnostics indicated failure of the pallet
amplifier.  In-house repair failed Friday night, so I sent the
driver chassis to Harris in Quincy, Il.  Harris technical is
working on it now (I sure hope).  I should have a prognosis
for repair this afternoon.

  Does anyone know of the existence of a spare driver that
might work or of a place that has LP digital transmitters ready
for emergency rental?

  My cell number is (805) 331-1839.

  Thanks, Dave Williams,

  NIST Radio Station WWVB will be conducting a test of a
phase-modulated broadcast format beginning at 1800 UTC (12:00
noon MDT) Tuesday, August 21 and ending at 1800 UTC (12:00 noon
MDT) on Friday, August 24,  2012.  During the test period the
broadcast will be randomly switching between the normal WWVB
broadcast and the new phase-modulated broadcast format.

  Radio-controlled clocks and watches will not be affected
by the test.  Phase-locking 60 kHz timing and frequency standard
receivers may lose lock during the test, but will restore during
the normal broadcast period.  For more information, e-mail WWVB
broadcast manager John Lowe at john.lowe (at) or
call 303-497-5453.
