                      THE MT. WILSON REPORT
******************************************************************
  STRAIGHT FROM DENNIS DOTY
  Things on Mt. Wilson are getting back to normal and we hope
they will stay that way for a while with the improved weather.
However, Angeles Crest Highway from La Canada to Red Box is
still closed and the closure is a pain for many folks that
come from the LA side, see map:
  http://earthsignals.com/add_CGC/DETOUR_Mt_Wilson.pdf
  The Wrightwood route is open but that doesn't help most
people.  We get a few folks each day asking how to get into LA
as they came from Wrightwood, missed the Upper Big T turn and
thus their opportunity to take the grand scenic route to Sunland.
They end up here, on Wilson, lost.
  I have heard two rumors about Angeles Crest reopening from
LA Canada to Clear Creek.  The first one reported it should be
reopened by Nov 2011 (yes, 2011).  This came from Cal Trans staff
in the area.  The second was reported by a Caltrans Flagger who
said he heard it may be done by fall this year.  We are all
hoping for sooner rather than later.
  SCE still has Par working on the backup power line that was
destroyed in the Station Fire.  This week a bunch of wire spools
materialized in Par's staging area here on Wilson.  I saw an
email that the line from Redbox to Wilson was not in this first
part of the repair effort but should be getting started soon
pending the Owl Nesting study that is in progress.
  Our weather station is working well despite a power
outage today in the rack that supports the system.  Otherwise,
everything has been working great and we are getting tons of
hits:

  http://weather.mtwilson.net  -  The main "full info" page.
  Some people here on Wilson are having problems with DSL orders.
If you need help, drop me a note and I will provide you with my
account info and that will help you place a painless order.
  With all the rain and snow this year, the brush is growing
fast and thick.  Please make sure to get your brush cleared ASAP.
We had some brush fires last week elsewhere in the county and
don't need them up here!
  One final note: Watch out for snakes.  LA County has responded
to a few snake bites in our area.
  Stay safe.  See you next month.

                        HD RADIO EDITORIAL
******************************************************************
  WATCHING THE FM HD RADIO INTERFERENCE POT BOIL
  o  The KATY and KMLA interference complaints come at
an inconvenient time for iBiquity and the NAB since these
organizations have just asked the FCC to dismiss opposition
to the FM HD Radio power hike:
  http://radioworld.com/article/101238
  o  It is interesting that anonymous "engineers" have suddenly
appeared in trade publications with outlandish arguments in an
attempt to divert attention from the real question:  Did the
addition of HD Radio on KRTH create new interference inside
KATY's normally protected 60 dBu contour or not?
  http://www.insideradio.com//Article.asp?id=1815245&spid=32061
  ______
  Here are facts concerning KRTH's HD operation as determined
  by CGC engineers (neither KATY nor KRTH are CGC clients):
  o  FCC-required spacing between the KATY and KRTH transmitters:
  113 km.
  o  Actual spacing between the KATY and KRTH transmitters:
  134 km.
  o  Thus, KATY and KRTH are separated by 21 km more than the
  FCC-required distance.  Docket 80-90 considerations are moot.
  KATY meets the minimum distance test and that's what counts.
  o  Analog effective radiated power currently assigned to KRTH
  as a grandfathered super powered Class B station on Mt. Wilson:
  51,000 watts.
  o  Analog effective radiated power KRTH could run at its
  elevation on Wilson if it were not a grandfathered station:
  760 watts.
  o  Thus, KRTH runs 67 times or 18.3 dB more power than a
  conventional Class B station.  If it weren't grandfathered,
  KRTH's power would be drastically reduced because Mt. Wilson
  is so highly elevated.  The 67 fold grandfathered power
  applies to KRTH's analog operation as well as its HD operation
  meaning that the HD is "red hot" (even at -20dBc injection).
  ______
  o  The number of comments in the KATY case continues to
grow in the RBR story cited earlier by the CGC Communicator.
The comments are located here, right after RBR's story:
  http://www.rbr.com/radio/24360.html
  o  Leslie Stimson and Radio World have performed an
outstanding service by Web-posting recordings of the alleged
KRTH-HD-to-KATY-analog interference.  The audio is at this
URL but allow time for the 6MB file to download:
  http://tinyurl.com/KATYaudioRecordings
  KATY's claim of HD interference from KRTH is reasonable
considering not only the large amount of power run by KRTH
(67 times the Class B limit when KRTH's elevation is considered),
but the fact that KRTH's upper HD sideband sprays noise power
directly into KATY's first adjacent analog channel.  That's
because of a major design flaw in FM HD, and a similar flaw
exists in AM HD.  This is why some call IBOC operations
"In Band Off Channel" instead of "On Channel."  The HD data
is sprayed into adjacent channels.
  The interference to KATY appears to be a magnified version
of the interference about to befall first adjacent channel analog
stations across the U.S. as HD power levels are cranked up by 6
to 10 dB.  And you won't need to be next door to a super powered
giant to feel the heat.  Have your multipath fades become worse?
Maybe it's first adjacent channel HD interference.
  CGC welcomes comments from both KATY and KRTH and will
consider publishing special newsletters with their comments.

  WIRELESS POWER
  Here is a critical look at transmitting electrical power
without wires.  It turns out that inductive coupling is only
practical over a distance of a few feet and even then there
are human exposure to RF issues that cannot be ignored.
