  "SPECTRUM SHARING" TEST-BED FREQUENCY BAND DESIGNATED
  The FCC has designated 10 megahertz of spectrum in the
470-512 MHz band as a Spectrum Sharing Innovation Test-Bed
and has identified procedures for interested parties to conduct
technology tests in that band.  The Test-Bed is intended to
provide a venue for demonstrating techniques to provide for
better sharing between Federal Government and non-federal
radio users.

  EXPERIENCED RADIO ENGINEER AVAILABLE
  Paul Sakrison, for the last 6 years Chief Engineer of CBS
Radio's KNX and KFWB in Los Angeles, is looking for his next
challenge due to the recent corporate downsizing at CBS.
  Paul's experience includes high power AM and FM transmitters,
directional AMs, digital studio audio systems, studio facility
design, HD Radio, web streaming and general equipment maintenance.
He is able to work with managers, talent and staff in a friendly,
professional manner with the ability to get things done on time
and within budget.  Paul is one of those people who strives for
high quality and high reliability -- an engineer that "gets it."

                       LETTERS TO THE EDITOR
******************************************************************
  MEET THE MT. WILSON DISTRICT RANGER
  For those who I haven't met yet, I am the "new" (if one year
on the job can still be considered new) ranger on the Los Angeles
Rivers Ranger District.  I would like to convene a meeting of all
the stakeholders along Mt. Wilson (which I define as from the Red
Box intersection to the Observatory and off to the sides).  I
view this as the first meeting of many in which we can talk about
topics of concern and address issues in a collaborative manner.
  Some of the topics which I would like to touch on, but not
necessarily solve at this first meeting, would include:
  o Mt Wilson Road, both after hours and RF issues
  o Hazardous fuel reduction
  o Ongoing Forest Service projects
  Also, we can add other topics.  Maybe the first meeting can be
half day (unless the discussion topics warrant a longer time) and
we can decide how we want to keep this group going....
  I am proposing to meet at the Supervisor's Office in Arcadia
on any of the dates of March 11, 12 or 13.  Please let me know
what works for you and feel free to forward a copy of this letter
to anyone who you feel should also attend.
  Thanks and hope to see you there.
  Michael J. McIntyre, District Ranger
  Los Angeles River Ranger District
  (818) 899-1900 ext. 223

  P.S. The invitation is for more than the Mt. Wilson electronic
folks... though they make up probably 90 percent of the users on
the mountain.

  PICTURES FROM MT. WILSON AFTER THE STORM PASSED
  Following are several Mt. Wilson snow and ice pictures taken
near the KPFK(FM) transmitter plant after the heart of latest
Mt. Wilson storm passed (see CGC #827).  This may not seem like
a lot of snow to some, but it was a very big deal for Mt. Wilson.
Falling ice destroyed one or more tower-mounted ice shields.
  According to one report, "Both KPFK and KKGO were off the
air because the STL antennas were iced up to the point the feed
probes no longer worked."  Both STL antennas sustained physical
damage from ice besides.  Photos by Bob Conger.

  IN THE WAKE OF TOWER STRUCTURES
  Four former employees [of Tower Structures, Inc.] have formed
two new companies, based in north San Diego County, CA, to offer
many of the same services.  Ocean Steel and Soelberg Construction
offer design, fabrication and installation services.  The four
individuals have in excess of 100 years of combined experience
in the tower and communications industries.  By teaming our two
companies, we will be able to offer high quality products at
highly competitive prices.

  ON THE PROPOSAL TO INCREASE HD RADIO TRANSMITTER POWER
  More information on the proposal to increase HD Radio
transmitter power levels by up to 10 dB may be found at the
URL below.  However, one CGC Communicator reader suspects that
analog receivers have typically blended to mono when HD cuts out,
so the request for more HD power is a bit disingenuous.  The
reader states that, "The quality of this monophonic reception
is not comparable to that of the stereo reception HD provides."

  RE DISABLED CARS NEAR THE EMPIRE STATE BUILDING (CGC #827)
  I was informed early on about the article concerning the
circle of car problems by the Broadcast Manager of the Empire
State Building, Joe McGuire.  Joe asked me about it when the
article first came out.  The building at that time did not
have a formal position on the complaint.
  After reading the various articles, I am of the opinion
that there could be a third-order intermodulation product of
the (A + B - C) type occurring in the automobile remote access
system.  Third order products, as you know, always occur in the
receiver, and in this case, the minor lobes from the antennas
on the Empire State Building could be related to these problems.
This is, of course, mere speculation on my part.
  It is an interesting problem, one that would be fun to track
down.

  RE PROLONGED CELLPHONE USE MAY AFFECT YOUR HEALTH (CCG #827)
  The evidence for cell phone data is weak, and unconvincing.
The study listed below does nothing to change that, particularly
because the odds ratios reported in the studies are weak, second
relative to the confidence interval, there's no statistical
difference between the reported odds ratios and chance.  Please
review the attached report from 2007 evaluating the available
research to date.

  XLNC(FM), 90.7 MHZ, IS OPERATING ON 104.9 MHZ -- PART II
  The last CGC Communicator said:
  "We note that 104.9 MHz is not authorized for use anywhere
in Baja California North ["BN"] according to FCC's FM Query
page, but hopefully that's just an oversight on the part of
the Commission."  This week, the FM Query page has lit up with
three allocations for 104.9 MHz in BN and they are located in
Ensenada, Mexicali and San Francisco (San Francisco is the
name of a community in Baja California).
  One of our readers, using professional allocations software,
suspects that the Mexican FCC has cleared the San Francisco
allocation for use on Cerro Bola mountain by XLNC.  However,
the allocation has severe radiation restrictions toward the U.S.
(toward San Clemente and Palm Springs in particular), so the
facility will probably fail to deliver a meaningful signal to
greater San Diego if it is built as authorized.  Signal reports
from three XLNC listeners in San Diego County all point toward a
weak and unsatisfactory signal on 104.9 MHz, but the reception
should be fabulous south of Cerro Bola mountain.
  These limitations notwithstanding, the 02/07/08 update to
XLNC's Web page is as follows:  "We are pleased to announce that
we will be moving to 104.9 FM on Sunday, February 10th at 10 AM!"
The next posting (02/10/08) suggests that XLNC is starting to
realize that it has a coverage problem.

  DOUG GARLINGER LEAVES KNBC FOR INDIANA
  Doug Garlinger has been one of KNBC-TV's top RF gurus 
on Mt. Wilson.  Friday was his last day on the job with KNBC
because he has accepted a job as Senior Broadcast Communications
Engineer with Qualcomm's MediaFLO division.  Doug will be based
in Indiana (close to his daughters) and will be missed by many
out here.  Best of success Doug!

  OFF TOPIC: REPLAYING THE RED MOUNTAIN FIRE
  On October 23, 2007, fire swept over the top of the Red
Mountain radio communications complex in Fallbrook, CA.  Now,
images from an HPWREN research Web camera installed at the site
have been stitched together into a movie that shows the flames
approaching and then engulfing the mountain peak.
  The camera is perhaps 40 to 50 feet above ground level on
the CalFire communications tower atop Red.  The camera is pointed
east.  Just after the video starts, watch along the bottom edge
of the picture and just a little to the left of center.  A portion
of the Red Mountain Reservoir comes into view as firelight is
reflected off the water.
  It is remarkable that the Web camera survived and was able
to provide these graphic images.  Although the power poles feeding
Red were destroyed in the blaze, most of the electronic equipment
continued to operate because the site switched to generator power.
This video is courtesy of Ron Patten of the Fallbrook Amateur
Radio Club who patiently stitched the frames together.
