  SOUTHERN CALIFORNIA WILDFIRES CREATE BROADCAST CHALLENGES
  The astounding wildfires in southern California captured
nationwide attention last week and challenged broadcast
engineers with equipment failures and the need to devise work-
arounds.  Our opening story (first URL below) was written by
Gary Stigall, Director of Engineering for XETV/FOX-6, and
quickly covers the technical events in San Diego County on
a day-by-day basis.  Don't miss the photo link at the end.
  A somewhat different view of the technical aspects of
covering the fires is presented by Broadcast Engineering
magazine, see the second URL below.
  The third and final URL takes you to a spectacular photo
of the San Miguel Mountain fire taken by John Berry, K6JWB,
at about 4 a.m. on Tuesday, October 23, 2007.  John graciously
allowed us to share his handiwork with you.
  As mentioned in CGC #813, all of Fallbrook was under
mandatory evacuation last week, so our office was closed.
No sooner did we return than we walked into a public safety
radio interference case.  Fortunately, our frequency and
spectral monitoring lab worked flawlessly and the interference
was resolved on short order.

                       LETTERS TO THE EDITOR
******************************************************************
  HAVING YOUR 87 MHZ CAKE AND EATING IT TOO, DTV STYLE
  As CGC Communicator readers know, some CH-6 LPTV stations
have converted themselves into 87.7 MHz FM stations.  They use
their aural carriers on 87.75 (or 87.74 or 87.76) MHz to broadcast
to the general public and simply keep their video carriers on the
air because it is an FCC requirement that they do so.
  When the DTV transition occurs, however, these LPTV
broadcasters will presumably lose the lucrative ability to
act like FM broadcast stations.  Not so, thinks one New York
LPTV operator.  This operator is reportedly interested in
transmitting 8-VSB and, at the same time, injecting an FM signal
on 87.9 MHz (perhaps because that frequency is more accessible
to FM receivers than 87.7 MHz).  The question is whether adding
an FM carrier in the DTV passband is legal.  One CGC Communicator
reader writes as follows:
  "The earlier [scheme of using the analog TV aural carrier to
broadcast to FM receivers] I know to be permissible under Part 74,
Subpart G.  I'm not so sure about this [new scheme of injecting
an FM carrier into the DTV spectrum], but at first blush, if this
hybrid stays within the modulation envelope contemplated in 74.g,
then it might fly."

  JOHN RUSSELL PASSES AWAY
  We were informed today by a former employee of KLCS-TV
that John Russell lost his battle with cancer this morning.
John was formerly Chief Engineer of KLCS as well as KCAL and
KTLA.  He was very active in the SCFCC and ham radio.
  We should have more information soon at KLCS.  I expect
that our Chief Engineer, Jim Mason, will have the details as
soon as John's family is ready.

  BOB VAILLANCOURT MOVES TO HAWAII
  October 30, 2007 was the last day for Bob Vaillancourt at
KNSD-TV, San Diego.  He is packing up and heading for KHON-TV,

  DOCUMENTS FLOWING FROM THE NINTH HLCC HELD IN MEXICO CITY
  The U.S. Department of State has released three U.S./Mexican
documents of interest flowing from the Ninth Meeting of the
United States-Mexico High Level Consultative Commission (HLCC)
on Telecommunications.  That meeting was held in August.
  The documents of interest are a Joint Statement (read it
first), a Directory of Bilateral Issues and a Protocol for the
Allotment and Use of the 138-144 MHz Band (if you are interested).
Look for the three items dated 08/03/07 at the following URL:
