  A New Chairman, a New Era

  As predicted, president Obama has announced his intention to
nominate wireless telecom and cable executive Tom Wheeler as the
next FCC chairman, and designate Commissioner Mignon Clyburn to
the role of Acting Chairwoman once current Chairman Julius
Genachowski steps down.


  The Chairman's Departure is Set

  "I have an announcement to top all announcements," said
FCC Chairman Julius Genachowski recently.  He said this Friday,
May 17, will be his last day on the job as Chairman of the FCC.


  FCC News Briefs

  o  The FCC will consider adopting receiver standards.
  While some believe this proceeding was in part devised to
  save LightSquared, the results could lead to a more efficient
  use of the electromagnetic spectrum overall but probably with
  some financial impact on consumers:

  o  The FCC proposes to expand the availability of in-flight
  broadband for airline passengers:


  LightSquared Reincarnated

  The FCC recently said LightSquared could temporarily use
1675-1680 MHz to test whether its mobile network can coexist
with government use of that spectrum.

  In contrast, LightSquared said the temporary usage will
test whether NOAA's meteorological operations can be moved to
a different band of spectrum, if LightSquared uses its current
band (whatever that means).

  Sounds like some investigative reporting is needed to
determine if the FCC is once again showing unusual favoritism
toward LightSquared.

  Illicit Prison Communications

  Promoting technological solutions to combat illegal cell
phone use in prisons can save lives and protect prison workers,
other inmates and the general public.

  There are three basic methods to accomplish this goal:
(a) electronically determine the positions of any unauthorized
phones and send in the guards to confiscate the phones, (b) set
up a "managed access or detection system" to block unauthorized
equipment use, or (c) send out jamming signals to block all
phones all the time, including phones owned by prison staff.

  This Notice of Proposed Rule Making looks at these options,
makes proposals and invites Comments:


  FCC Enforcement Watch -- California Primarily

  o  Notice of Violation issued to KVMX(FM), Bakersfield,
  for overmodulation:

  o  KRML(AM), Carmel, is issued an NOV for a laundry list
  of alleged violations including not having a designated Chief

  o  It is always a good idea to keep your Public File complete
  and up to date as this Consent Decree between the FCC and KCET(TV)
  indicates.  KCET's $6,000 "voluntary contribution" is just a
  minor part of this big settlement:

  o  Failure to repaint a tower as required to maintain good
  visibility, failure to display the Antenna Structure Registration
  Number in a conspicuous place so that it is readily visible, and
  failure to notify the FCC immediately upon a change of ownership
  of the tower structure results in a proposed $25,000 fine:

  o  Mobile Relay Associates, licensee of WQGW503, Chatsworth,
  is busted for hogging a 150 MHz frequency, not using trunking
  technology when apparently required to do so and failure to
  I.D. as required:

                           Random Notes

  Radio Notes of Interest

  o  EMI standards were set for the LA Metro light rail lines
  according to the IEEE.  However, there is no indication in this
  paper's abstract that the FCC-based RFI limits were met, meaning
  that broadcast (and other) radio signals could get clobbered
  (we know that some AM interference is in fact occurring):

  o  As one reader commented on the Metro Gold RFI, "...I hope
  that the FCC will come down hard on the issue [of protecting
  AM broadcast radio].  After all, it is the FCC's responsibility
  to protect this spectrum from abuse."

  o  The new NRSC-G301 guidelines from the National Radio
  Systems Committee are now available.  The guides cover the
  creation, packaging and delivery of program metadata for
  receiver displays:

  o  A tower-to-insulator arc-over at the new KBRT(AM) site
  and NAB Show news from an engineer's perspective -- it's all
  right here in the latest newsletter from Crawford Broadcasting:

  o  Saving AM radio, more details from the NAB Show panel:

  o  Internet Radio is making its way into vehicles, slowly
  displacing traditional broadcast:

  o  Mobile streamed listening is growing rapidly:

  o  Emmis CEO "won't rest" until FM radio is in every
  smartphone, opening a new market for over-the-air broadcasting:


  TV Note of Interest

  NAB has formally requested that the FCC lift its freeze
of TV station modification applications.


  Internet TV

  It seems very likely that major broadcast TV programs will
eventually be distributed over the Internet in real time.  The
questions are when, and under what legal controls?  Major cracks
are developing in the walls that separate broadcast TV from the
Internet, and important eyes are watching the developments.

  In the interim, if the courts don't stop Aereo from putting
over-the-air TV content onto computers and smartphones, networks
such as Fox and CBS have said they could suspend free over-the-air
broadcasting and serve only pay-TV viewers, or so they claim.


  General Notes of Interest

  o  The "spire" is raised to the very top of One World Trade
  Center in New York, and the Durst Organization is pitching TV
  and FM broadcasters to move their transmitters and antennas
  to the new location:    (short video)    (text)

  o  San Francisco gives up its battle for cell phone RF
  radiation labels:

  o  Interesting claim: All digital phone calls and e-mails
  -- yours included -- are being archived by the U.S. government:

  o  EAS expert Richard Rudman is collecting signatures
  urging Congress and the Executive Branch to enact legislation
  for a national public warning strategy:

  o  There were no call sign changes in our part of southern
  California according to the FCC's latest change list:


  LED Light Bulb Hazard

  Certain 120 VAC LED light bulbs can overheat and cause fire
or smoke.  554,000 lightbulbs sold under the brand names Definity,
EcoSmart, Sylvania and Westinghouse are being recalled.

  If you own an affected LED, stop using it.

                            Off Topic


  Regarding this story in CGC #1198:

  o  There is a surprisingly inexpensive and potentially
  very beneficial treatment for Alzheimers and perhaps a
  number of other serious conditions:

  Two readers point out that coconut oil is not a proven
treatment despite the tantalizing preliminary results shown
in the video.  For the other side of the story, see:


  High Standard Off Topic Material - Educational Postings

  o  Concrete canvas shelters -- buildings delivered in a bag.
  This is very neat:

  o  Many different technologies were squeezed into the iPhone,
  making it a technological marvel (see the comparison photos):

  o  It's interesting that 48 copies (or substantial portions
  of copies) of the original 600 year-old Gutenberg Bible exist,
  yet not one copy of the first Website made just twenty years
  ago survives, until now:

  o  Palomar Observatory will assist in the worldwide search
  for gravitational waves and, if detected, the next steps will
  be to DF (direction find) them to determine their origin:

  o  Recycling at its finest, a picture essay:

  o  "It has become appallingly obvious that our technology
  has exceeded our humanity" - Einstein:


  Some Pretty Wild Stuff:

  o  This exclusive video from the Tanzania Olympic site
  demonstrates conclusively that Giraffes can swim:

  o  That's right dear, our ancestors had tails:

  o  Street-legal bumper cars:

  o  Another delightful kid commercial:
