  FCC CREATES SPECTRUM POLICY TASK FORCE
  To confront the seemingly impossible task of keeping up with
the ever increasing demand for spectrum, the FCC has created the
Spectrum Policy Task Force ("SPTF") headed by Dr. Paul Kolodzy,
Senior Spectrum Policy Advisor, Office of Engineering and
Technology, FCC.  The new group will include attorneys,
economists and even engineers.
http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-223142A1.doc
  SPTF is off to a running start by inviting public comments
on a wide array of fundamental questions.  Here are just a few:
How could the Commission define and quantify spectral efficiency?
Should "site" licenses (e.g. broadcasting and private land mobile)
be converted to geographic area licenses?  Are new definitions of
"interference" and "harmful interference" needed?

  Comment are due July 8, 2002 - Replies July 23, 2002.

  EXPERIMENTAL GRANTS
  The Commission has granted a number of experimental requests
including this one of local interest:
  WC2XTY - CONSULTING & ENGINEERING NEXT GENERATION NETWORK INC.:
2418-2473 MHz for aeronautical to land-mobile communications
tests.  Mobile: Southwest United States....

  FCC FORFEITURE WATCH - SELECTED ITEMS
  The FCC has affirmed a $10,000 fine to the Rev. Dr. Philius
Nicholas of Brooklyn, New York for operating a radio transmitter
on 88.1 MHz without a license.  In a similar action, a $10,000
fine against Tom Brothers was upheld for the unauthorized use
of 88.3 MHz in Berkley, Michigan.

  MAJOR RDS TEXT EFFORT TO BE LAUNCHED IN L.A. ON JUNE 15
  dMarc Networks, Inc. (dMarc), a subcarrier management and
wireless data distribution firm, has announced the production
launch of its patent-pending dRDS (Dynamic Radio Data Service)
system, which allows text to be broadcast and appear on car radio
data screens.  dRDS is making its debut on five major L.A.-area
radio stations - KHHT 92.3, KYSR 98.7, KIIS 102.7, KOST 103.5 and
KBIG 104.3 - in coordination with a Clear Channel concert being
held June 15.

  XM STUDIOS BUILT IN A RATHER UNSAFE PART OF WASHINGTON, D.C.
  Check out (this) URL.  It is interesting how the author
points out that XM Satellite built their facility in a rather
unsafe part of Washington, DC.  As a clever security move, XM
leases space to the Police Department.

  WAITING FOR THE COMPUTER TO WARM UP
  Nothing quite like a computer motherboard with "tube sound"

  A CORNUCOPIA OF CAMOUFLAGED CELL SITES
  Jim and Marvin are correct: Each of the three flagpoles at
the SR134/SR2 interchange are cell sites.  By the way, the generic
term "camouflage" is preferred over "stealth" as the latter is a
trademark for a specific manufacturer of camouflaged cell site
structures.  For many examples of camouflaged and well hidden
cell sites, as well as some not so well camouflaged, see:
  http://www.CableTV.com/
and click on Wireless Page, and follow the photos link (see
"Interesting wireless site photographs"  -Ed).

  MORE ON HIDDEN CELLS
  Regarding the cellular flag poles, I am sure there are several
companies that produce "Minimum Visual Impact" structures. Valmont,
however, might be the name most familiar to broadcasters.  Valmont
owns Microflect (line entry ports, etc.) and PiRod.  A sample can
be seen at:

  RE: WLW(AM) INTERFERENCE PUZZLE SOLVED BY HAMS
  Glad to see credit given here for a tremendous group
effort.  I should point out that two of the hams who were
major contributors to finding the solution were Geoff Mendenhall,
W8GNM (as noted in CGC #517), VP-Advanced Product Development,
and Jay Adrick K8CJY, VP-Strategic Business Development, both
at Harris Corporation's Broadcast Division in Mason, Ohio.

  SEEING THE SOLAR ECLIPSE WITH MICROWAVE EYES
  Monday's partial solar eclipse attracted quite a bit of
attention because the event could easily be seen.  However,
the sun is also a powerful source of microwave signals, so the
eclipse should have been visible in the radio spectrum as well.
  Thanks to the efforts of Dr. Brian L. Dougherty of Caltech,
we now have graphs of the solar microwave eclipse.  Dr. Dougherty
operates a microwave dish in the Owens Valley that records the
radio spectrum of the sun every 9.6 seconds, covering roughly 100
frequencies between 1 and 18 GHz.  With a bit of data processing,
we are able to "see" Monday's solar eclipse with microwave eyes:

  Many thanks to Brian for this outstanding work.  We hope it
will inspire some of you to visit the Solar Radio Burst Locator
page <http://srbl.caltech.edu/> during the day to see the sun's
microwave events in real time.
