  FCC NEWS BRIEFS

  o  Legislation will "constrain us from maximizing the [TV]
  spectrum recovered" - FCC chairman Genachowski in an article
  on the new Incentive Auction Task Force:
  http://tinyurl.com/SpectrumConstrained

  o  DTV RF Channel 51 has been identified as a possible
  source of interference to the 700 MHz band:
  http://tinyurl.com/CH-51-IX-Implicated

  o  The FCC has granted a Section 325(c) permit to send
  program material across the border to XEWW, 690 kHz, Tijuana:
  http://tinyurl.com/XEWW-325c-Permit

  o  The FCC made key LPFM and FM Translator decisions ahead
  of schedule last week, so the Commission simply deleted those
  items from its Open Meeting agenda:

******************************************************************

  LPFM ROUNDUP

  o  The Commission still has some important issues to
  decide before flinging open an LPFM application window.
  The following story explains what work lies ahead:
  http://tinyurl.com/LPFM-MorewDecisionNeeded

  o  Should 250 watt LPFMs be allowed in rural areas?
  Should 10 watt LPFMs be eliminated or retained?
  http://tinyurl.com/Details-on-LPFM-Powers

  o  Enthusiasm abounds from LPFM supporters.  (The reality,
  of course, is that some full power stations will lose valuable
  fringe area coverage over wide areas because of interference
  caused to them by the LPFMs, while the LPFMs cover relatively
  small areas):

  FCC ENFORCEMENT WATCH -- CALIFORNIA PRIMARILY

  As reported in CGC #857 dated September 23, 2008: "KUSI-TV, San 
Diego, [was] fined $25,000 for failing "in a timely manner to make 
accessible to persons with hearing disabilities emergency information 
that it provided aurally in its programming for KUSI during a 
wildfire emergency in the San Diego, California area on October 26 
and October 27, 2003.""

  On March 16, 2012, following an appeal by KUSI, the Forfeiture 
Order was canceled and the case was effectively closed.  To resolve 
that little matter took only three and a half years, a court case 
and considerable legal fees.

  ATTENTION COMMUNICATION SITE OWNERS/USERS ON
  SOUTHERN CALIFORNIA FOREST SERVICE LAND  -  PART 3

  This continues our series on anti-perching devices and other 
stipulations applicable to four Forest Service National Forests 
in our area:

  A copy of the 1999 settlement between the Southwest Center for 
Biological Diversity and the Forest Service is available at the URL 
below (settlement attachments not included).  This is apparently 
the document that led up to some of the anti-perching stipulations 
given in Appendix G.

  For those interested, scroll down about 40% through the settlement 
document to numbered paragraph 5 where this language
appears:  "Consistent with the recommendation of the Condor Recovery 
Team, the USFS will require installation of anti-perching devices on 
all microwave sites within the four national forests at issue in 
this case."

  So, what exactly did the Condor Recovery Team have to say, what is 
the definition of a "microwave site," what is the basic concern 
about condors at microwave sites and what radio frequency experts 
(if any) were consulted in the formulation of the now- mandated 
remedies?  The SCFCC has expressed a willingness to help interface 
with the Forest Service and their contributions will be sincerely 
appreciated.

  o  Be there no mistake.  The 199 foot height limitation on
  new towers in Appendix G is applicable to Angeles National
  Forest towers (e.g. Mt. Wilson).  See Roman numeral "I" at:
  http://tinyurl.com/ForestServiceAppG-Angeles

  o  Informal reports indicate that the USDA Forest Service
  has for years required the use of anti-perching devices at
  a number of their communication sites in the Santa Barbara
  area including the KTMS (990 kHz)/KTYD (99.9 MHz) site.

  o  With respect to installing a bunch of short wires as
  anti-perching devices, one engineer wrote as follows:

  "It has always insulted my sense of rationality to see
  hundreds of dipoles taped to areas in the near and semi-near
  fields of antennas - they take a 1 ft hunk of #12 or 14 steel
  wire, bend it into a V and staple it to a strip, and double
  sticky tape the strip to the "horizontal surface" and think
  that is wonderful.  The "non interference" version of the
  anti-perching wires is exactly the same thing with the V
  of steel wire encased in plastic...."

  o  If you have comments on our Appendix G stories,
  please post them on the Tech Letters Website mentioned
  below.

  GENERAL NOTES OF INTEREST

  o  There is an important reason for allowing text-to-speech
  converters for audio EAS messages as this article explains:
  http://tinyurl.com/Text-to-Speech-for-EAS

  o  In-car Internet radio seems to be on the verge of
  becoming a mass-market reality:

  o  On the virtues of spot welding AM (and sometimes FM and
  perhaps TV) tower sections together:
  http://tinyurl.com/SpotWeldingVirtues

  o  The TVFOOL Website is a perennial favorite for DTV
  coverage patterns.  We are advised that it now has "overlays
  for Google Earth that include all TV station transmitter
  locations and their Longley-Rice coverage patterns:"
  http://www.tvfool.com/

  o  KSCI has ordered an ERI UHF-TV antenna to replace their
  collapsed Andrew antenna (see CGC #1108).  Same radiation
  pattern as before.  The station hopes to have the new antenna
  on the air by early June.  (Verbal information from KSCI)

  o  Los Angeles LPTVs KNET-CA, KNLA-CD and KNLA-LP are being
  sold for $16.4 million:

  o  AmericanRadioHistory.com is a treasure trove for radio
  and TV history.  They even have old Broadcasting Yearbooks in
  a searchable format.  ARH would appreciate the loan of classic
  documents for scanning and Web-posting:

  ROAD ICE HAZARDS -- A SNOWPLOW DRIVER'S VIEW

  The following e-mail is from a southern California road maintenance 
worker.  He happens to drive one of the snowplows that services one of 
our 5000(+) foot broadcast sites.  The issue is road ice -- something 
that can be treacherous for some time after a snowfall or freezing 
rain occurs.  Here are his thoughts:

  "I love how all you think the worst is over, when you all should 
take into consideration the road is shaded all the way up the hill 
which means that there are icy roads.  Then the second worst thing 
is the falling ice off all of your towers.
So the storm is not always the problem -- it's the couple of days 
after the storm that is truly the worst."

  Points well taken.

  ULTRATHIN FLEXIBLE BATTERIES

  Coming:  An ultrathin flexible battery.  In the works from Japan-
based NEC for over a decade, the organic radical battery is just 
0.01 inch thick, can refresh a teeny screen 2,000 times and can be 
recharged in less than a minute.  In 2013, it'll appear in enhanced 
credit and debit cards that display balances, in hotel keys, in 
subway and train passes, and in much slimmer and lighter smart 
phones.  It'll also pave the way for slender flat-screen displays 
and e-readers that feel like paper.
