  ONE VERY IMPORTANT REPORT ON FM HD RADIO
  If you have time to study only one article this week, this
is the one, at the URL below.  It's a synopsis of NPR Labs'
findings on what happens when FM HD power is cranked up without
safeguards in place.
  The results aren't pretty.  "Sobering" is the polite word.
No wonder iBiquity has been afraid of this study.  No wonder
they tried to rush the FCC to grant a blanket power increase
before this study could be done.
  If just one HD interfering signal will do the damage depicted
in the article's one and only chart, think of what multiple HD
signals will do.  Meanwhile, Mr. and Ms. John Q. Public are
clueless as to why their analog coverage isn't as good as it
used to be.
  FM engineers need to explain the NPR Labs synopsis to their
GMs and PDs.  Show them the chart.  Explain the devastating
ramifications of FM HD power increases without stringent
safeguards in place.
  This is serious stuff.

                      THE MT. WILSON REPORT
******************************************************************
  A QUIET WEEK, AND THE BEAR IS GONE FOR NOW
  All has been well on Mt. Wilson this past week but there are
still a few road issues.  The "S2" Angeles Crest Highway route
is open to permit traffic with some construction delays from time
to time.  Angeles Forest Highway is passable but the County would
prefer that it not be used due to missing guard rails, and road
crews working on shoulders, signs and drainage.
  I had a little run-in with the bear last Sunday and gently
chased him/her for about a mile in my truck honking the horn along
the way.  Haven't seen the critter since.  Next on the agenda is
serious winter weather.  The rock and mud slides are guaranteed
to make life very, very interesting.

  YOUR CAR WILL BECOME A FARADAY CAGE
  Metalized (heat reflective) windows will be phased into
new vehicles sold in California.  This means that radio signals
won't get into or out of your vehicle as easily as before, and
that may cause problems as this story explains:

  POTENTIAL ARSONIST INDICTED
  A special criminal grand jury has indicted Rickie Lee Fowler,
a 28-year-old prison inmate, on arson and murder charges in
connection with the Old Fire wildfire in October 2003.  If we
are not mistaken, the Old Fire was the one that destroyed a
number of broadcast transmitters as shown below:

  A PECULIAR MONTH FOR FREQUENCY MEASUREMENTS
  October 2009 was a very unusual month for CGC's frequency
and spectral monitoring service because so many problems were
discovered (often there are few or none):
  o  At AM stations, there were two noteworthy events: The
GPS had unlocked at one station, shifting the carrier frequency
only slightly (fortunately); at another station the HD Radio
encoder was intentionally turned off after staff reportedly got
tired of the poor analog fidelity forced on the station by HD
operation. (AM HD requires that the analog audio be low pass
filtered.)
  o  We found one FM station off frequency (beyond FCC specs),
and another that was off the air without their even knowing it.
  o  Many LPTV stations are still broadcasting in NTSC; one
had a drifting colorburst frequency while another had a colorburst
that was beyond FCC frequency specs.
  o  In the HDTV department, one station had a "hunting" pilot
frequency (apparent GPS unlock), while another had a wandering
pilot (it was on Frequency A for three minutes, then on
Frequency B for three minutes, then the cycle repeated).  Another
HDTV station had jumped down in frequency over 1,000 Hz relative
to last month's reading, while yet another station lost its
19,403 Hz offset when a control board was replaced.
  All of the problems were reported to the affected stations
and most of the repairs have already been made.  Again, this was
a very unusual month for measurements!

  FCC ADDRESSES HAM RADIO PUBLIC SAFETY DRILL ISSUE
  The FCC has addressed an important and difficult question:
When (if ever) may ham radio operators conduct public safety
drills on ham radio frequencies on behalf of their employers?
  Some aspects of this official Public Notice will be discussed
at length in ham circles.  Please do not send us your comments
but do direct them to ham publications.

******************************************************************
  INCIDENTAL RF RADIATION MAY BE ANYTHING BUT INCIDENTAL
  I was on a recent flight on AirTran Airlines and if you had
WIFI, you could use your laptop PC on board.  Many people did!
  I started thinking:  All these Class B devices radiating
interference or "junk" across many frequencies and the FAA still
will not allow a headphone AM/FM radio to be used on board.
Is something wrong here?
  Speaking of Class B devices, I think it is time for the FCC
to re-evaluate these devices.  They are everywhere and they are
interfering with AM/FM radios and more.
