  DTV TRANSITION: ANALOG SHUTOFF SUMMARY FOR SO. CALIFORNIA
  The following southern California full power television
stations have discontinued or will discontinue analog broadcasting
by February 17, 2009 according to a just-released FCC list.
Stations not listed below will presumably shut down on June 12
unless otherwise noted in this newsletter:
  Bakersfield DMA:
  KBAK, KERO, KGET and KUVI
  Los Angeles DMA which includes a wide area:
  KHIS (Barstow), KVMD (Twentynine Palms) and KJLA (Ventura)
  Palm Springs DMA:
  All stations will switch later, presumably June 12
  San Diego DMA:
  KFMB, KGTV and KSWB
  Santa Barbara - San Luis Obispo DMA:
  KSBY, KTAS, KEYT, KPMR, KCOY
  Yuma - El Centro DMA:
  All stations will switch later, presumably June 12

which the above data were derived:

  The next URLs give two different ways of viewing the best
list published (because it's comprehensive with the stations
switching by February 17 shown in red):

  Our thanks to FCC staff who worked at lightning speed to
publish this information on such short order.  Job well done!

  DTV SWITCH NOTES
  o  San Diego is an unusual market because KPBS-TV will
probably terminate its analog service about the end of March,
as mentioned in earlier CGC Communicators.  So, San Diego has
three switch dates: February 17, approx. March 31 and June 12.
  o  In Mexico, XETV has signaled its intent to terminate
CH-6 analog operations on February 17; however, that does not
preclude the station from retooling CH-6 for some other purpose,
perhaps DTV.  We do not know their long-range plans.
  o  Neither XHAS, nor XHDTV at Cerro Bola, will shut down
analog operations until forced to do so by Mexican law according
to a reliable source in Mexico.
  o  KPMR in Santa Barbara is reportedly having second thoughts
about shutting down on February 17 according to a CE in that area.
  o  The above source also reports that, "All stations in the
[Santa Barbara - San Luis Obispo] market have analog translators
and LP transmitters as well.  I can't state with certainty, but
I believe all of the analog translators and LPs will remain in
operation, in analog mode for the foreseeable future."

                       LETTER TO THE EDITOR
******************************************************************
  INTERMOD ALLEY
  Regarding the DTV channel plan below, I believe the Los
Angeles market will have the only six, first-adjacent UHF DTV
channels in the country:
  31 - KTLA
  32 - KDOC
  33 - KTBN
  34 - KMEX
  35 - KRCA
  36 - KNBC
  KTBN was recently granted permission to switch to CH-33
completing the "six-pack" channel cluster shown above.
  For those that follow, or attempt to follow, Charles Rhoads'
articles in TV Technology magazine, where he has calculated and
demonstrated the intermod problems with three adjacent carriers
in a non-linear receiving device (i.e., an overloaded consumer
tuner or preamplifier), the intermod possibilities of six
adjacent carriers are staggering to imagine.
