  DELANO SHORTWAVE FACILITY TO BE SHUT DOWN IN OCTOBER
  The International Broadcasting Bureau (IBB) will stop
shortwave broadcasting from Delano, California, at the end of
October according to Radio World.  The facility will be converted
to "cold storage standby status" but some equipment may be
moved to other locations in the IBB network.
  The Delano station began shortwave broadcasts to the
Pacific Theater of World War II in 1944.  Delano is located
about 140 miles north of Los Angeles.

  FCC TESTS UNLICENSED DEVICES IN THE TV BAND
  FCC Chairman Kevin Martin recently said that within a week
the FCC would release the results of tests of several remote-
sensing unlicensed devices that would potentially be allowed to
operate in the so-called "white spaces" between DTV channels.
The FCC has already said it plans to allow fixed devices in the
band subject to testing and other safeguards to make sure the
devices do not interfere with TV reception.

  SOME IN CONGRESS FEAR DISASTROUS OUTCOME OF DTV CUTOVER
  What will happen on February 18, 2009 when tens of millions
of analog television sets receiving over-the-air signals receive
nothing but noise?  With only $5 million allocated to educate the
public about how the new digital signals can be received, many
on Capitol Hill fear the outcry will focus on them unless TV
broadcasters can achieve what the government has so far failed
to do: make the viewers aware.

                       LETTERS TO THE EDITOR
******************************************************************
  REPLY COMMENT ON FM HD RADIO ADJACENT CHANNEL INTERFERENCE
  Responding to the "Long Form Reply" to my letter posted
in CGC #800 regarding "IBOC spectral regrowth," I know what we
measured.  I heard the interference before the bandpass filter
was installed.  Installing the bandpass filter cleaned up the
digital noise and interference caused by spectral regrowth
intermodulaton products on the station operating on the second
adjacent channel above us.  When IBOC was turned off the
interference went away.
  Spectral regrowth is a problem with the HD technology.  It
occurred in Denver and other markets.  My intent was a friendly
warning to those operating IBOC or that are about to do so --
please watch for and carefully measure out-of-channel and out
of mask emissions.
  Elliott Klein, Klein Broadcast Engineering, L.L.C.
******************************************************************
  AND A NEW COMMENT ON THE DENVER HD RADIO INTERFERENCE CASE
  I'm familiar with the Denver spectral regrowth case and
have even laid eyes on the filter that fixed the problem.  The
Class C in Denver is Entercom's KALC "Alice" on 105.9 and the
rim-shot, KJAC, is licensed to Timnath with its transmitter site
in a canyon way up north.  KJAC is owned by local billionaire
Philip Anschutz.
  I told the local Entercom folks when this first came up that
if their spectrum was clean, I'd tell the KJAC people to take
a hike.  But there was some fear of local backlash (billionaires
evidently carry a lot of clout), so they played the game and even
took their digital signal off altogether for awhile.  I'm
guessing that KJAC (who also operates in the HD hybrid mode) also
wipes out KALC within the KJAC 100 dBu contour, but there's
nothing up there but elk, bighorn sheep and maybe a moose or two.

  TIS COMMENT
  Despite the recent FCC actions against illegal Travelers
Information Station programming, I still find a lot of the
stations running non-legal programming.

  HEALTH WATCH SPECIAL - TOMOTHERAPY
  Marvin Collins, retired Chief Engineer of KFI(AM) & KOST(FM),
Los Angeles, has just finished a series of X-ray radiation
treatments for prostate cancer.  Marv received his treatments
on a fascinating new machine made by a company called TomoTherapy.
  First, the machine precisely images the abdomen using low
powered X-ray beams and CT scanning.  Then the operator lays a
computerized treatment template over the image telling the machine
to put lots of radiation on the prostate while protecting critical
organs nearby - just like designing a 3-D directional antenna
array.  Finally, and without removing the patient, the machine is
switched into the treatment mode and high-powered custom-shaped
X-ray (aka "photon") beams from many different angles are
converged on the prostate while sparing neighboring tissue.  The
machine can be used to treat other fixed-location cancers too.
  The first URL below is Marv's personal account of his
treatment sessions and some good tech-talk including a photo of
the inside of a TomoTherapy machine (click on any photo to
enlarge). The second URL links to a 4-minute video by TomoTherapy
showing how their machine works.  Engineers will feel right at
home with the colored "dose delivered" charts -- just like the
computerized field strength charts we use in broadcasting.  See
the third URL for even newer treatment technology that is under
development, and the fourth URL for the American Cancer Society's
recommendations on annual prostate screenings.
  Questions?  Marv can be reached at kfiam640 (at) aol.com
and we thank him for sharing this valuable and very personal
information with CGC Communicator readers.  Prostate cancer
impacts one in six men - it's an enormous problem.

  S.D. COUNTY OPTS FOR NEW ALERT SYSTEM TO REPLACE REVERSE 911
  Encouraged by the success of a 12-year association with
the Reverse 911 alert system, San Diego County supervisors have
approved a new contract with a different vendor for technology
that is faster, less expensive, more flexible and Internet-based
to satisfy the need to alert residents when evacuations are
necessary.  The new vendor is Twenty First Century Communications,
and use of the system will be made available at no charge to all
cities and local agencies within the County.

  METAL THEFT - A NATIONWIDE PROBLEM
  Whether it be copper radials, stainless steel beer kegs,
manhole covers, air-conditioning units, power cables, catalytic
converters, light poles or aluminum bleacher seats, metal thieves
continue in their quest to profit from valuable metals being
sought by unscrupulous recyclers.  Some states and local
governments are tightening ordinances to discourage the practice
by holding recycling companies accountable, but the thefts
continue as some foreign nations rush to satisfy their need
for raw materials.

  HEALTH WATCH - PHIL WELLS TO LEAVE THE HOSPITAL TODAY
  Former broadcast engineer Phil Wells is scheduled to go
home from the hospital today.  All tubes are out and he is
finally tolerating food.  We spoke with Phil yesterday and he
asked us to thank everyone for their prayers and good thoughts.
(And please keep them coming -- home recovery will not
necessarily be a piece of cake.)
