  The gala SCFCC "Christmas Party" for broadcast engineers is set for 
Wednesday, November 16, 2011.  Festivities start at 10 AM sharp with 
an informal meeting of the Southern California Frequency Coordinating 
Committee (SCFCC) followed by a catered lunch and great conversation.

  The location is the original KCBS transmitter building at the first 
(gigantic) tower on your right just before you reach the very top of 
Mt. Wilson.  KCBS was the site of the first SCFCC Christmas Party back 
in the 80s.

  Please RSVP to Howard Fine with your name, title, entity and how 
many will be in your party.  As usual, neckties are strictly 
forbidden.  Hope to see you there!

  Comments filed with the FCC continue to run in favor of changing the 
way commercial FM broadcast stations are allowed to be moved and 
improved leading to greater spectral efficiency.
See the lead story of CGC #1091 for technical details.

  The latest support for protecting only actual on-the-air contours 
comes from the Mississippi Association of Broadcasters (MAB).  This is 
significant because MAB's members include 100% of Mississippi TV 
stations and 85% of Mississippi radio stations.

  Consider filing Comments in RM-11643.  Friday is the deadline.
We believe that this rule making proposal is on the right track.

  The FCC has released a new drawing entitled "Spec it Out!"
to publicize what it contends is an upcoming Internet spectrum 
shortage and how to ameliorate that shortage through voluntary 
spectrum auctions.

  Curiously, there is no encouragement for people to conserve spectrum 
by adopting any one of a number of "green practices" in how they 
connect to the Internet (e.g. the use of wired connections when 
available or highly localized RF links to accomplish the same thing).

  We are also beginning to see studies indicating that use of personal 
wireless Internet devices while on the job leads to a decrease in 
productivity because workers are distracted by social networks, 
streaming video, etc.  It would be curious if the FCC's "spectrum 
shortage" mantra is aiding and abetting a decrease in national 



  An agenda has been announced for the October 31, 2011 Workshop/
Webinar on rapidly deployable aerial communications architecture for 
disaster venues.



  The FCC has ordered FM Translator station W284BQ, Detroit, MI, to 
"immediately cease operation" for reasons of unresolved co-channel 
interference to a full power station.  The translator operator could 
not or would not resolve the interference.  Instead, the operator 
offered smartphones to impacted listeners of the full power station 
so those listeners could hear the full power station over the Internet 
instead of over the air.

  Unfortunately for W284BQ, that novel approach was not FCC rule 



  o  P&Y Broadcasting Corporation tentatively fined $3,000
  for failing to immediately notify the Commission of a change
  in ownership for antenna structure number 1246297 (KMPC(AM)):

  o  Daniel K. Roberts a/k/a "Monkey Man" a/k/a "Monkey"
  ("Roberts"), San Francisco, tentatively fined $10,000 for
  repeatedly operating a pirate station on 87.9 MHz:



  The Small Business Administration has something called the Office of 
the National Ombudsman.  ONO is "available to assist small entities 
with federal agency enforcement and compliance matters."  What 
specific use this office serves remains unanswered.

  If you know of a good use for this office, let us know.

                           RANDOM NOTES


  o  Clear Channel engineers prepare for the Nov. 9
  national EAS test:

  o  Those using a Sage Digital ENDEC model 3644 need to take
  special precautions before the upcoming Nov 9 national EAS test:

  o  Here is a wonderful interview with Sam Wallington,
  V.P. Engineering, Educational Media Foundation:

  o  There is progress on approving asymmetric HD sideband power
  for FM stations to reduce adjacent channel interference:

  o  The Commerce Department has identified 1,500 MHz of
  federal spectrum to further evaluate for wireless broadband:

  o  LightSquared is being a bit uncooperative, as usual:

  o  Check out this gem, a 32 GB flash chip in a micro-SD
  card about the size of your thumbnail:

  o  ViaSat-1 was launched into orbit Wednesday right on
  schedule.  If all works as planned, the broadband bird will
  markedly reduce the cost of satellite Internet connections
  across the U.S. -- including in FCC-cherished rural areas:

                          HAM RADIO NOTES

  700,000 HAMS

  The number of ham radio operators in the United States
  has topped 700,000, an all-time high.



  Here is a very different digital receiver, the Radio Jet 1102S, 
similar to Software Defined Radio yet not SDR.  Curiously, there is 
no AGC; there are adjustable attenuators instead.
A spectrum analyzer is included as are audio and IF recorders.
A most interesting box:
