 FCC NEWS BRIEFS

 o  REC Networks reviews the LPFM landscape and notes that
 perhaps eighteen LP-100 channels will become available in Los
 Angeles if second adjacent channel waivers are granted:

 o  Telcordia approved as a TV White Spaces database
 administrator, the second such entity approved by the FCC:

 http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-12-465A1.doc

 o  NTIA makes a spectrum swap offer involving the 2 GHz
 BAS band but there are costly complexities making a complete
 swap unlikely:

 o  The FCC, the Department of Education and various vendors
 are intent on transitioning all K-12 schools to digital textbooks
 in five years (which in turn will give bureaucrats the ability
 to amend the curriculum and indeed change written history at the
 push of a button).  Welcome to the "digital textbook ecosystem"
 (FCC's phrase, not ours):

 o  South Bay Aviation, Inc. at Torrance Airport fined $300

 THE MT. WILSON REPORT BY DENNIS DOTY

 Mt. Wilson had a few electric power hits lately so interested
 parties are going to meet with Southern California Edison (SCE)
 soon....

 The Cosmic Cafe in the Pavilion is open again on weekends....

 The snakes are coming out so watch your step, and don't forget
 about getting a jump on brush clearance -- important for fire
 protection.

 That's about it for now from the top of Mt. Wilson.  Stay safe.

                          RANDOM NOTES
******************************************************************

 ATTENTION COMMUNICATION SITE OWNERS/USERS ON
 SOUTHERN CALIFORNIA FOREST SERVICE LAND  -  PART 4

 We hope you are enjoying this series on anti-perching
devices that are apparently mandated on southern California
communications sites situated on Forest Service land.  Now we
would like to hear your thoughts before the SCFCC meets with
Forest Service representatives.

 Were it not for the fact that conducting-type anti-perching
devices hold the potential of generating significant long-term
radio frequency interference (RFI) effects, the whole subject
would probably be moot.  Site owners would simply pay X dollars
to have the devices installed and be done with it.  And you can
bet that most site owners would select the least expensive
option to the detriment of all parties involved.

 The communications industry needs to proceed with extreme
caution before adorning their towers and buildings with crowns
of thorns.  These are permanent fixtures that carry real RFI
potential.

 Non-conducting spike strips are available; however, an
experienced contractor warns us that these devices do not last
long on sites impacted by snow and ice and have limited life on
other sites.  So, they become a maintenance headache.  Even the
wire-type spike strips inevitably become kicked or mashed to the
point where the wires touch each other and generate RFI.  The
same contractor commented that, "To date I have not seen an
avian fatality because of towers or guy wires."  This is the
same statement that we have heard so often from our readers.

 For archived CGC Communicator stories on "anti-perching"
devices, use the URL below.  You will learn, for example, that
the death of a single condor in the Los Padres forest reportedly
triggered the entire anti-perching campaign.

 Please share your comments and suggestions with us by
replying to the e-mailed version of this newsletter.  All
comments will be forwarded to the SCFCC and may be published
in future Communicator newsletters.  If you would like your
comments "anonymized," start by saying "anonymous comments"
and the editor of this newsletter will personally strip all
identifying information before your material is forwarded
or published.

 Thanks in advance for your input.  By working together,
we may be able to make some progress on this unusual case.

 KBRT'S TRANSMITTER RELOCATION -- SOLID PROGRESS

 April's Local Oscillator newsletter from Crawford
Broadcasting is hot off the virtual press.  Cris Alexander
explains the solid progress being made in the KBRT(AM) transmitter
relocation effort despite unexpected setbacks (page 1).  In other
news, Bill Agresta discusses the latest challenges in keeping
KBRT's current Catalina Island transmitter on the air.  With
the random "Island Factor" at work, the unexpected is the
norm (page 8).

 MAGNITUDE 3.3 EARTHQUAKE SERVES AS A SAFETY REMINDER

 North San Diego County experienced a Magnitude 3.3
earthquake Thursday at 11:09 PM -- a small quake by all standards
but a good reminder to secure equipment in anticipation of "the
big one."

 The X-Y coordinates for Thursday's earthquake are about half
way down South Grade Road on Palomar Mountain.  Click on the Web
address below, then "zoom in" several clicks on the map scale (hit
the plus sign or drag the scale slider upwards) to pinpoint the
epicenter.

 If you put the coordinates listed on the page into your GPS,
you can almost drive to the location -- and if you find a pot of
gold don't forget to share.

 G-MAIL TAP

 There is a new and fast way to enter text into a mobile

 MIT -- NUMBER ONE AGAIN

 Perhaps the best known ranking of graduate schools is
provided by U.S. News & World Report.  MIT has held the top spot
in engineering since 1990 and did it again in the new 2013
listings.

 In addition, four MIT engineering departments were ranked
No. 1: chemical, materials, computer and electrical.  Other No. 1
departments at Tech: economics, mathematics, earth sciences,
chemistry, physics, and computer science.
