  FCC & LEGISLATIVE NEWS
  o  House passes TV Nightlight bill, permitting some analog
  TV stations to continue broadcasting for 30 days after Feb 17
  with essential and emergency information. President yet to sign.
  http://www.tvnewsday.com/articles/2008/12/11/daily.8/
  o  The Los Angeles FCC field office has established a somewhat
  confidential DTV hot line.  It is for the purpose of requesting
  written materials and speakers on the DTV transition -- it is
  not for use by the general public having reception problems.
  Please replace the telephone number published in the last
  Communicator with this new number: (562) 865-2702.
  o  FCC Media Bureau announces Comment and Reply Comment dates
  for the Second Further Notice of Proposed Rulemaking regarding
  the disturbance of AM broadcast station antenna patterns.  This
  involves the construction of new towers, such as cellular
  towers, near AM broadcast stations:

  THE KSON(AM) REPLACEMENT TOWER NEARS COMPLETION
  Three prominent southern California broadcast towers
collapsed in late 2004, namely the KFI, KSON and KXO tower
structures.  KFI, Los Angeles, is of course back on the air
with its new tower.  The good news is that KSON(AM), San
Diego, is about to follow suit.
  As many of you know, the top half of KSON's tower folded
over in 2004 and was removed.  The following photo taken at
dawn on December 10, 2008 shows the remaining half of the old
KSON tower (left), and the beautiful new replacement tower
almost ready for use (gin pole still on top).
  Thanks to Eric Schecter, former CE of KSON, for furnishing
the new photo and clearing it for publication.

                       LETTERS TO THE EDITOR
******************************************************************
  AN ELEGANTLY SIMPLE DTV READINESS TEST
  TV stations in the state of Michigan will be offering
small tests for viewers to see if they are ready for the DTV
transition.  It is real simple.  If a viewer sees a green screen,
they have passed the "test" and are ready for the transition.
If a viewer sees a red screen, they have failed the "test"
and will need a converter or a new TV.

  COMMENTS ON THE AURAL POWER INCREASE SOUGHT BY KSFV-LP
  In response to this story in CGC #871...
  "There is news to report in the "Channel 6 acting as an FM
radio station" department.  KSFV-LP, CH-6 on Mt. Harvard (adjacent
to Mt. Wilson and serving Los Angeles), has been cited by the FCC
for running almost eight-times the allowable aural transmitter
power.  Their aural transmitter is apparently primarily used
to broadcast to FM receivers tuned to 87.7 MHz...."
  ...and this Letter to the Editor is CGC #871:
  "Yeah, and now [KSFV is] asking the FCC to allow them to
  [run excessive power] legally.  Now THAT'S chutspah!  Here
  is KSFV's request:
  http://earthsignals.com/add_CGC/KSFV_LP_Waiver_App.pdf 
  ...two new Letters to the Editor have been received.  They
are presented below.
******************************************************************
  COMMENT #1
  Just a couple of comments on the channel 6 FM situation.
The KSFV transmitter is in the same room with KUSC so I am
somewhat familiar with their system.
  The notice of violation says that KSFV's Aural ERP was much
too high.  But the FCC did not measure the ERP; they looked at
the transmitter power.  The antennas are fed by two different
sized feedlines so that accounts for some of the difference.
One can conclude nothing from the transmitter power measurements
without knowing the details of the antenna/line system gains
and losses.
  And, as KSFV's waiver request indicates, they were an LPTV
upgraded to Class A and no operational changes would have been
required.  LPTVs can legally operate with equal aural and video
power as well as 75 kHz deviation and standard FM stereo.
  I have questioned this type of operation from the beginning,
but I can't blame stations for trying to get all the coverage they
can.  If they do it within the rules, or if the FCC grants things
we don't like, we need to work to change the rules and/or the
FCC interpretations rather than act as though the stations are
bandits.
  Lyle Henry, Los Angeles, lylehenry (at) fastmail.fm
******************************************************************
  COMMENT #2:
  I read the petition [to allow KSFV-LP to run more aural
power] and find it to be the most outlandish thing I've read
in a long time.  If the FCC grants this, let alone does not cite
them further for excessive modulation, then the FCC has themselves
become corrupt.  The rules are very clear on the deviation allowed
for television stations and by no stretch of the imagination can
anyone interpret those (TV) rules to allow 75 (73) kHz main
channel deviation.
  Burt Weiner, biwa (at) att.net
  P.S.  The 73 kHz deviation comes from the sum total of
allotted deviations for the BTSC main channel and subcarriers
for TV.  The rules have been twisted and interpreted to mean you
can run 75 kHz deviation.  Not true!  +/- 25 kHz is the maximum
deviation for the main channel audio, the audio that lies between
50 Hz and 15 kHz -- it's in the rules.
******************************************************************
  KEEP AND EYE ON THE SUB-CHANNELS YOU BROADCAST
  CGC Communicator reader Dan Ramos, Huntington Beach, CA
caught an unusual event on KCET-3 (KCET-DT sub-channel 3)
on December 6, 2008.  According to Dan, this channel usually
broadcasts VMe, the Spanish language version of PBS, but
on the evening of December 6 Dan found the following:
  "I am watching KCET digital KCET-3 and there is a shot of
the KCET studio with people milling about...  The channel I am
watching should be VMe but [that] programming is gone.  This
has been going on since 6:15 PM.
  [Update]  "It looks like they are preparing for a live
broadcast!!  A small studio audience has been bought in and
seated.  Telephone volunteers have been seated...but are not
taking calls.  I guess this will be live probably at 7 or 8 PM.
The camera shots keep changing.  I noticed a mike has been left
on and I can hear people talking....  No one cussed during
this episode so KCET's license is safe for now...."
  This unfortunate incident is a great reminder for all of
us to monitor our broadcast channels carefully and regularly.
This applies to the multiple channels on both TV and HD-radio.

  OFF TOPIC COMMENTS
  Regarding CGC #871 and the Off Topic video showing an
airplane with a missing wing land successfully due to the
presumed incredible efforts of an acrobatic pilot, the following
offering from youtube does a pretty good job of debunking the
video:
  http://www.youtube.com/watch?v=J72y_qFV2oc&NR=1
  Rick Hunt of Entravision agrees:  "Things are happening way
too quickly for this to be a full scale plane, especially the
plane going from a wing-vertical to a wing-horizontal position
just before landing.  Then the tail bounces at least 2 meters
into the air yet falls back to the ground in milliseconds when
a gravity-induced fall from 2 meters would take over a half
second.  Also, the aircraft appears to decelerate from landing
speed to a stop in an unusually short period of time and distance.
Finally, the plane does not appear to have a tail wheel but
instead has a tail skid (common on models), and the plane has
no registration numbers.
  "As a flight instructor who has signed hundreds of solo
endorsements, I've seen a lot of planes bounce many times and
agree with the analysis that this video is a fake."
  Editor's Note:  We all need to be cautious about fake videos;
they are too easily manufactured today.  CGC thanks Jim Walls
who first spotted the debunking video, and Rick Hunt <rhunt
(at) entravision.com> for adding his thoughts.

  OCCASIONAL OUTAGES AT WWVB
  WWVB, the time and frequency station that synchronizes
radio-controlled clocks and wristwatches across the U.S.,
occasionally goes off the air.  The reason behind a recent
outage is surprising -- and turns out to be an ongoing problem:

  SKELETON CREW
  CGC will be operating with a skeleton crew over the
Christmas Holidays.  Your holding all but the most urgent
correspondence until after the New Year would be appreciated.
  Merry Christmas and Happy Holidays from the staff at CGC!
