  EDITORIAL:  CHAIRMAN GENACHOWSKI ADDRESSES THE NAB
  FCC Chairman Genachowski's speech at the NAB Show in
Las Vegas was so well crafted that some people came away with
the belief that there wouldn't be serious consequences if TV
broadcasters failed to return sufficient spectrum to the FCC.
  While the Chairman expressed his optimism that enough TV
spectrum would be voluntarily returned to satisfy the Commission's
goals (his speech is posted at the first URL below), nothing
was said that would rescind the tough language in the National
Broadband Plan outlining what could happen if the voluntary
approach failed.  To see the Draconian steps for yourself,
scroll down to page 92 in the Plan (second URL below).
  Numbered para. 4 on page 92 is entitled "Explore
alternatives..."  This is where the rubber meets the road.
Equally alarming is numbered para. 5 on the same page where the
FCC wants Congressional authority to impose fees on full-power
commercial TV licensees for spectrum use -- a step that could
easily drive reluctant broadcasters to relinquish some or all
of their over-the-air assets.
  After Genachowski's speech was delivered, the audience was
informed that he would take no questions, and he promptly left
the stage.  "Of course!" said one reporter sitting next to the
editor of this newsletter.
  Fortunately, NAB President Gordon Smith is hanging tough
against the FCC's TV spectrum grab, see the third URL.

  OUTSTANDING MOUNT WILSON ROAD MAP
  A clear and concise map of the paved roads leading to
Mt. Wilson is available at the URL below.  The map was produced
by the Mount Wilson Observatory ("MWO") and shows the open and
closed roads as of March 16, 2010.  Because this map is so
concisely drawn and includes road names, it's a keeper!

  BIG LANDSLIDE REROUTES TRAFFIC TO MT. WILSON
  On April 21, Mike McIntyre, USDA Forest Service District
Ranger for the Mt. Wilson region, commented as follows:  "(This
is) what CALTRANS is dealing with."  Two photos were attached.
Nothing further was said.  Judging from the photos, this was one
huge landslide (click on the images for enlargements):
  http://earthsignals.com/add_CGC/Images/Caltrans_trbl.html
******************************************************************
  THE DENNIS DOTY REPORT
  o  I believe that Mike's landslide photos depict the slide
  that closed the Angeles Crest Highway a few months ago and is
  still being cleared.  The slide occurred between La Canada and
  Clear Creek, see the Mt. Wilson Road Map [two stories above].
  I have heard unofficial reports that this segment of the Angeles
  Crest will remain closed until November 2011 -- yes, 2011.
  o  Regarding the backup power feed to Mt. Wilson that was
  destroyed by the Station Fire, SC Edison, via its subcontractor
  PAR, has been very busy replacing the feed.  It's good to see
  the activity.
  o  The old dirt Toll Road serving Mt. Wilson will be closed
  May 6-7 so a 30 ton boulder blocking the road can be blasted and
  the debris removed (per Forest Service e-mail).
  o  A hiker was bitten by a rattlesnake a week ago on the Toll
  Road and was air lifted by LA County, so it is time once again
  to be especially wary of snakes.
  o  The Mt. Wilson weather station is working well.  Give it
  look:

  INCREASED FM HD POWER CONTAMINATES YOUR ANALOG CHANNEL W/NOISE
  Consulting engineer Barry McLarnon is just as amazed as
we are that NPR and FCC caved in and agreed to allow most FM HD
Radio stations substantial power increases.  The bottom line is
that 6-10 dB increases in HD power add noise (substantial noise)
to your analog channel, to say nothing of causing increased
adjacent channel interference.  Heavy audio compression can of
course mask the noise to your own station, but compression leads
to listener fatigue.
  If you care about your analog signal, proceed with caution.

  DTV SHAPEFILES
  A zip file containing the ETSI shapefiles used in connection
with the DTV coverage maps that were published by the FCC in 2009
has been posted by the FCC because of popular demand.
  These shapefiles were used to prepare the DTV coverage maps
released June 5, 2009 showing the predicted digital service of
every full power television broadcast station as of the day after
the [first] DTV transition.  The shapefiles were prepared from
an April 30, 2009 extraction of the Commission's Consolidated
Database for Broadcast Services, and do not necessarily represent
the current operating status of the stations.  Neither the maps
nor the shapefiles are being updated, and no support is provided
on their use.

                  INVITED LETTER TO THE EDITOR
******************************************************************
  FM HD RADIO: CAN TUBE-TYPE AMPLIFIERS HANDLE THE LOAD?
  CGC #1004 carried a story entitled, "FM Station Cranks
Up HD Power, Clobbers Another Station."  In response to a
CGC query, the representative of a transmitter manufacturer
stated as follows:
  "It seems that tube rigs may not be well suited for HD
unless very carefully supervised, or things like this [the
production of wideband RF noise] occur.  The tube can lose
its peak capability without its average power even dropping --
so you might think everything is okay -- but as [your reader's
story indicates], it sure isn't."
