  o  The FCC has released updated LPFM spectrum
  availability data files addressing technical "water file"

  CALM ACT GOES INTO EFFECT

  The CALM Act, designed to keep TV commercial volume in-line
with program audio, went into effect on December 13, 2012.  FCC:
"A commercial may have louder and quieter moments, but overall
it should be no louder than surrounding programming."

  ASSAULT ON INTERNET FREEDOM

  Remarks from FCC Commissioner Robert M. McDowell:

  "Today, America's delegation to the World Conference on
International Telecommunications (WCIT)... stood strong for
Internet freedom when it proclaimed that it would not sign
new international rules that capture the Internet.  Our
delegation's resolve should be commended....

  "Even though the United States refused to sign the new
agreement, what happened today in Dubai could have ripple
effects here at home... but the worst is yet to come...."

  PEERING INTO AN FCC FIELD INVESTIGATION

  "Manchester Ignored FCC Rules" is the title of a provocative
story from San Diego CityBeat magazine.  This article brings out
fascinating behind-the-scenes details of an actual FCC field
investigation conducted in San Diego County.

        FOLLOW-UP ON THE LAX AIRRADIO STORY (CGC #1180)
******************************************************************

  DESIGNING AN AM BOOSTER

  As a follow-up on our LAX AiRadio story (CGC #1180), it
is worth mentioning that Ben Dawson of Hatfield & Dawson served
as the consulting radio engineer on the booster system that
illuminated the Sepulveda tunnels with AiRadio signal.

  The seamless transition between the main site signal and
the tunnel radio (booster) signal was particularly memorable.
Ben thought about that feature long and hard in the design phase,
and was gratified that it worked so well.  We understand that
Ben Dawson and Burt Weiner worked closely on the final tunnel
antenna design.

  Ben said, "The most amusing thing about the tunnel system
was that the FCC form calls for antenna height AGL, and of course
it is negative.  The FCC computer program choked on that, and we
had to get them to modify their software to get the application
filed.  We had not encountered the problem with earlier software
in other "below ground" situations, such as the 800 MHz system
for the Port of Seattle at Seatac airport."

  GENERAL NOTES OF INTEREST

  o  Ozcat Radio (KZCT, 89.5 MHz, Class A, Vallejo) has been
  hit by vandalism for the third time since August, forcing the
  FM station to go off the air at least for a month, its owner
  said recently:

  AM/FM/TV CALL SIGNS GRANTED IN OUR AREA

  o  New FM, Old Dale (just east of Twentynine Palms), to KDAJ

  HELP FOR MEXICALI

  Information from three independent sources received in
the past week lead us to believe more than ever that the 940 kHz
station in Mexicali, Baja North, Mexico, is indeed off frequency
by about +173 Hz.  The station is shown in the FCC's database as
XEWV (1 kW day, 100 watts night, non-D) and is better known as
XEMMM.  The alleged off-frequency operation of XEMMM even
appears on a published list of such anomalies, see the
first URL below.

  We hope one of our engineering friends in Baja will verify
the problem, contact XEMMM and lend a hand in cleaning up the
situation.  XEMMM's Website indicates it is an ABC Radio
affiliate.

  DECODING THE DISNEYLAND TELEGRAPH

  Here is a fascinating detective's story of how a ham radio
operator discovered some errors in the Disneyland Telegraph system
on display at the New Orleans Train Station at Disneyland/Anaheim,
and how those errors were resolved.  A classic story of curiosity
and engineering excellence:
