  FCC FREES UP VACANT TV AIRWAVES (THEIR WORDS, NOT OURS)
  FOR SUPER WI-FI TECHNOLOGIES
  Heads up.  This is the White Spaces proceeding we have been
discussing.  A Second Memorandum Opinion and Order (Second MO&O)
has been released.  As the FCC put it:
  "The Federal Communications Commission today [9/23/10]
took steps to free up vacant airwaves between TV channels --
called "white spaces" -- to unleash a host of new technologies,
such as super Wi-Fi, and myriad other diverse applications.
This is the first significant block of spectrum made available
for unlicensed use in more than 20 years...."
  Aside from our industry's well founded belief that white
space devices will have a detrimental effect on over-the-air TV
reception, the Commission did "reserve two vacant UHF channels
for wireless microphones and other low power auxiliary service
devices in all areas of the country."  So, at least a modicum
of forward thinking was used.
  Getting back to the TV interference issue, Amy Schatz,
writing in the Wall Street Journal on September 23, 2010, noted
that, "Consumers may not see new devices which use those airwaves
for several years, however.  The legal challenge by broadcasters
can now move forward."
  Following are the FCC news brief and the official MO&O
that addresses not only TV White Spaces and wireless microphones,
but certain other unlicensed spectrum issues as well.  The
remaining URLs are news stories concerning the MO&O.

  LPTV ANALOG SERVICE TO TENTATIVELY END SOON
  More big news.  The FCC is proposing that in-core (CH-2 to 51)
LPTV stations cease analog operations sometime in 2012 (exact date
to be determined), and that no further LPTV operations of any kind
be permitted in the CH-52 to 69 out-of-core spectrum after
December 31, 2011.  See para. 10 & 22 at the second URL:

  THE END OF FRANKEN FMs MAY BE NEAR
  It appears that when Channel 6 LPTV stations are forced
to switch to digital mode (tentatively in 2012), Franken FMs
will become history.  No longer will Channel 6 LPTVs be able to
exploit what they believed was a legal loophole that allowed
them to use their aural carriers (near 87.7 MHz) as de facto
FM broadcast stations.
  With DTV transmissions, there are no aural carriers.  The
video and aural signals are transmitted together in one large
data block.  So far, the broadcast industry does not seem to
be shedding a single tear over the demise of Franken FMs.
  The article that follows is somewhat outdated (4/23/10) but
does address the Franken FM issue.

                     THE MINI MT. WILSON REPORT
******************************************************************
  BACKUP POWER TO WILSON/HARVARD RESTORED
  Southern California Edison (SCE) confirms that backup
electrical power to Mts. Wilson and Harvard has been restored.
Part of the mountain is now being fed by the old 16 kV line
(aka the "Video" line which continued to provide power to Wilson
and Harvard during the Station Fire), while other parts of the
mountain are being fed by the recently rebuilt 33 kV line (aka
the "Broadcast" line).  The entire mountain can be run off
of one line if the other fails.  Transformers normalize the
voltage.
  CGC asked SCE whether the Broadcast line, which was destroyed
by the Station Fire, was rebuilt with wooden or metal power poles.
An official at SCE said, "We were forced to go with the wooden
poles because of a safety hazard that the steel poles created.
I will explain in a subsequent e-mail."
  We will wait patiently.
