  o  Important for radio:  On November 30 at its Open
  Meeting, the FCC plans to consider adopting key steps
  in the Low Power FM (LPFM)/FM Translator proceeding,
  important RF interference issues included:

  o  The adoption of ATSC 3.0 in the next 3-5 years may be
  crucial to television broadcasting:

  o  Comments and reply comments in the wireless microphone
  proceeding have been extended to 12/21/12 and 02/19/13

  o  The Media Bureau reminds DTV stations that their
  Annual DTV Ancillary/Supplementary Use Services Reports
  (FCC Form 317) are due on or before December 3, 2012:

  o  Admired consulting radio engineer Jules Cohen has died.
  He was in his 90s.  Mr. Cohen will remain as one of the true
  greats of his profession, an engineer's engineer:



  Thanks to the efforts of a sharp-eyed CGC Communicator
reader, we now know why the 530 kHz Travelers Information
Station at Los Angeles International Airport is silent.
Mark Nodine writes, "Los Angeles World Airports canceled
their recently renewed license for WNHV296 effective
October 1, 2012.  They no longer have a license."

  WNHV296 consisted of two transmitters, one to fill the
Sepulveda Blvd. tunnel under the runways (10 watts of power),
the other to broadcast to the general public (100 watts).
An FCC waiver was necessary in order to run 100 watts with
the above-ground transmitter.  That power level was granted
back in 2004 with some fanfare, the extra power being deemed
necessary to communicate with the general public in case of
a terrorist attack, see the first URL below.  You can read
about the demise of WNHV296 at the second URL.

  As an aside, the permittee still holds (but is not using)
WQEA967, 770 kHz, 10 watts, at Ontario International Airport.
It is described in the final URL.

                           RANDOM NOTES


  o  Dan McKinnon, a well known broadcaster who also had
  an outstanding career as a Navy pilot, has been honored
  in San Diego:

  o  San Bernardino County staff will not recommend a hearing
  delay in the Lazer FM radio tower case in Yucaipa:

  o  Final plea to stop the proposed KMJE radio tower falls
  flat with Yolo supervisors:

  o  Mobile devices stolen in the U.S. will no longer
  be activated in Mexico, and vice versa, under this new
  international accord:

  o  Watch for a White House executive order to impose
  certain security controls over the Internet (WSJ, subscription
  usually required):

  o  LightSquared has filed a Petition for Rule Making
  asking the FCC to allocate the 1675-1680 MHz band for
  terrestrial mobile use.  Public comments are invited:



  o  144 tons of stolen copper was seized before going to

  o  Cleveland, Ohio - Federal officials have charged a young
  man and woman with removing copper material from four towers.
  The total repair bill is estimated at $136,000:

  o  Possible mug shots of the Cleveland copper theft duo:

                          HAM RADIO NOTES


  There may be a Christmas present of sorts from ham radio
in space.  On December 24, Christmas Eve, the students in Japan
who built the FITSAT-1 satellite are planning to active the
bird's LED optical array and flash a message in Morse Code to
those of us here on Earth.  The students plan to start testing
the optical system at the end of November.  (Amateur Radio



  NASA's "PhoneSat" miniature satellite is coming to ham radio
  soon (a Tech Letters posting):

  The most recent Tech Letters postings include the following:

  o  Providing backup power to cell sites is not necessarily
  cost-effective or affordable considering that things other
  than the absence of power can take a site down.  Ray Grimes,
  a well known engineering consultant in the public safety
  sector, gives us his view:

                            OFF TOPIC


  A skunk apparently took down the KXRM-TV (Fox) transmitter
in Colorado Springs, CO.  Three fuses blew on the main power
feed and there was a distinct odor of burnt skunk scent in
the fuse area.  The incident happened Sunday night a week
ago and the outage lasted almost 24 hours.

  While the story at the first URL below is not accurate in
a number of technical respects (there was no broken tube for
example), the amazing part is that the skunk survived according
to KXRM's Chief Engineer.  The skunk hunkered down under one
of the racks and eventually sauntered out of the building.



  This year, 2012, marks the 35th anniversary of the death
of Bing Crosby, the American singer and actor, who was one of
the best-selling recording artists of all time.  But Bing had
another passion and that was recording technology, video
recording in particular.

  Here's an opportunity to learn about the technology in
question and what it was like to work with Mr. Crosby.



  o  How cool is this?  A one wheeled motorcycle, an
  engineering masterpiece.  Now we just need a long-lasting
  battery to go with this great invention:

  o  Last week we featured one new use for a Tesla coil,
  now here is another.  We suspect that the demonstrator placed
  conductive tabs over his fingertips to pull off this stunt
  without burning himself badly:

  o  Hawk flies through a hole in slow motion:

  o  A life turned around.  Very nice:

  May you and your family enjoy a warm and wonderful Thanksgiving.
