  WATCH FOR "WHITE SPACES" AND DON'T
  FORGET TO TAKE THE "INTERFERENCE TEMPERATURE"
  The FCC's Spectrum Policy Task Force has presented its
recommendations to modernize the Commission's rules that guide
how the nation's spectrum is managed, and to evolve from a
traditional government-based "command and control" model to a
more flexible, consumer-oriented approach.
  According to the task force, if someone is using their
spectrum only some of the time, why not let others fill the voids?
This could be accomplished through various digital modulation
schemes and Software Defined Radio, for example.  Also, if a
proposed operation won't raise the "interference temperature" to
other users beyond some predetermined level, why not let the
newcomer proceed?
  (Of course, AM broadcasters and others have been making
aggregate interference calculations for decades, so the concept
of total interference is not new, and the term "temperature"
suggested by the task force - while colorful - is unnecessary.)
  There is much more involved with the recommendations than
we can report here, such as promoting unlicensed spectrum
technologies such as Wi-Fi.  The Commission has not, of course,
endorsed any part of the report as yet, and there may be some
vigorous debate ahead.

  FCC ALLOCATES SPECTRUM FOR ADVANCED WIRELESS SERVICES
  AND PROPOSES LICENSING AND SERVICE RULES
  The Commission has allocated 90 MHz of spectrum (1710-1755 MHz
plus 2110-2155 MHz) for advanced wireless services and seeks
comments on licensing, technical, and operational rules.
  The spectrum could be used by current cellular/PCS licensees
to expand their capacity for offering wireless voice and data
services such as 3G.  Alternately, it could be used by others
to support the development of entirely new applications that are
distinct from existing offerings.

  FCC SEEKS COMMENTS ON PROPOSED LICENSING AND SERVICE RULES
  IN THE 5.9 GHZ BAND
  This Notice of Proposed Rule Making seeks comments on
the proposed licensing and service rules for the 5.9 GHz Band
(5.850-5.925 GHz) for Dedicated Short-Range Communications (DSRC)
in the Intelligent Transportation Systems Radio Service.
  DSRC systems are being designed to provide a short-range
wireless link to transfer information between vehicles traveling
at high speeds, or between vehicles and roadside units (fixed
or portable).

  FCC FORFEITURE WATCH - SELECTED ITEM
  The FCC has imposed a $133,000 fine against Callais Cablevision
(Grand Isle, Louisiana) for cable signal leakage and EAS
violations.  The action follows a complaint by the FAA about
interference to one of its remote air-ground communications
facilities.  The cable leakage was worth $125,000; the EAS
violation $8,000.

  GUY WIRE RETENSIONING, LAKE TAHOE STYLE
  KTHO, 590 kHz, South Lake Tahoe, was off the air for over a
day because its AC power and phone lines were destroyed.  This
is quite a story involving wind, fire, and falling trees.  Of
particular interest, trees fell onto the guy wires of the
station's 305-foot tower.
  The tower did not collapse, thanks to the Forest Service
crew who carefully cut the fallen trees piece-by-piece, gradually
reducing the stress on the guy wires rather than allowing them to
loosen suddenly.  However, the tower is now bent, as shown in
this photo sequence by Bill Kingman, CE of KTHO:
  http://www.steveblodgett.com/ktho.html
  On Sunday, 11/10/02, Bill added that, "This morning, four days
after the wind & fire, everything in those pictures is under two
feet of snow (that is) still falling."  The station is operating
at reduced power due to the temporary AC power feed.  Fortunately,
the tower lights are back on.  The KTHO tower is in the approach
path of the local airport.

  KVCR-TV, SAN BERNARDINO:  OFF THE AIR (AGAIN)
  From a KVCR press release dated November 8, 2002:
  "KVCR-TV, Channel 24 is off the air again.  The station
suffered a massive short in the antenna system sometime Thursday
evening, November 7, 2002.
  "Station management has decided to acquire a temporary low-
power transmitter and antenna to get the station back on the air.
The current transmitter and antenna system are nearly 20 years
old...."
  Lew Warren, GM of KVCR, advises that the current antenna may
have fallen victim to a lightning strike.

  RADIO ENGINEERING OPPORTUNITY
  A radio station in the greater Los Angeles area is looking
for an experienced engineer to fill the post of Chief Engineer.
High power RF experience is required.  One advantage is that
you would be working for a single station, not several stations.
  Interested applicants should send their names, telephone
numbers, best times to call and brief background information to
<rgonsett@ieee.org>.  Your e-mail will be forwarded to the
station for review, and the station has agreed to keep all
inquiries confidential.

  PETE SMITH PASSES AWAY
  Athel "Pete" Smith, of P&R Tower Company, Inc., and part
owner of Magnum Towers, both in Sacramento, passed away Monday,
November 4, at age 79, lung cancer.  Pete was instrumental in
[installing] many familiar towers we have today; his first major
tower project in California was the 1958 erection of the six
tower KCBQ(AM) array in San Diego County.
  Pete erected the KTHO(AM) tower shown in my pictures [see
related story above].  When vandals cut the top guy-wires from
one anchor in 1970, leaving the KTHO tower leaning badly, I
called Pete in Sacramento, 100 miles away.  About five hours
later, he informed me, "It's all fixed, Bill -- and, WOW!"
  Pete was like a sturdy, leathery-skin bronco-buster, with a
great love of life.  I last met with him two years ago when he
mounted a tower on the roof of Harvey's Hotel & Casino at South
Lake Tahoe.  He loved it!
  Pete surely knew how to erect strong towers.  I wish I could
call him for another rescue today.
  Bill Kingman, KTHO, South Lake Tahoe

  AN INVITATION TO A DIGITAL RADIO EXPERIMENT
  Digital Radio Mondiale, or DRM, is a project aimed to
revitalize the short-wave, medium-wave and long-wave AM radio
broadcast bands.  This, by using digital signals to provide
near-FM quality.
  Radio amateurs and serious broadcast listeners are being
invited to become part of the DRM Software Radio Project.
They may also be among the first to access the initial DRM
programs when test transmissions begin next month.
  James Briggs is the DRM Projects Coordinator with Merlin
Communications in Dorset, England.  Briggs says that the project
relies on adding an extra down-converter board to existing
receivers and then using software to decode the signal via
a PC soundcard.  The interface is simple and the sound
- hopefully - will be superb.
  The following website should have technical information
available next month:  http://www.drmrx.org/

  OVER 100,000 HAMS RESIDE IN CALIFORNIA
  Latest figures show that California has over 100,000 amateur
radio operators, making it the state with the most hams, and more
than one seventh of all the nation's hams.
  Only 1,575 hams reside in North Dakota, making it the state
with the least hams.
