  The web has matured to the point where many of the CGC
Communicator stories duplicate postings that are readily
available elsewhere, and often sooner than we publish them here.
  For national FCC news, we recommend you read the FCC Daily
Digest:  http://www.fcc.gov/Daily_Releases/Daily_Digest/2005/.
  For general broadcast engineering news, Radio World's "RW
Newsbytes" is the hot ticket.  This publication is short and
to the point, with web links when more information is needed -
miraculously like the CGC Communicator itself.  To sign up
for free weekly e-mail delivery of RW Newsbytes, visit
http://www.rwonline.com/.  Close to page top, click on the
line that reads, "Sign up for RW Newsbytes weekly email" and
complete the simple form.
  For the past year we have been pointing our readers to Gary
Stigall's BENX website and very much appreciate his efforts
in posting original stories, policing the Letters section and
rebooting the site whenever hackers took it down, which they
did repeatedly.  Sadly, the BENX site has been closed down.
  As luck would have it though, Gary has turned his considerable
talents to doing web postings of stories of interest, which
could be much more valuable in the long run.  We'll show you one
example of his handiwork later in this newsletter, which can
serve as a model for what you and your SBE chapter/s can do.
When your letter or story is posted on the web and you call it 
to our attention, we will consider posting the URL in the
Communicator so everyone can see what's up.
  2005 will bring better organization to the following sections
in the CGC Communicator: Local Broadcast Applications & Actions,
Call Sign Grants, and related items by dividing them into AM, FM
and TV categories for easier viewing.  We will also continue to
publish a few very special and unique stories.  Thanks for your
many suggestions in 2004, and may the New Year bring you and
your family health, happiness and great prosperity!
  Q.  Are there any new photos on the KSON situation?
  A.  Yes.  Visit Steve Blodgett's KSON web page and check
out the new offerings under "Photo Set Three."  There are
some very dynamic images - downright scary at times - showing
the removal of the wayward tower section that acted a bit
like a windsock.  Steve's page is at:
  Q.  Has any official information been published on the KSON
tower calamity?
  A.  John Buffaloe, Engineering Manager for Jefferson-Pilot
Communications Company of California, has published his firsthand
report on the collapse, the tricky removal of the bent-over tower
section and the restoration of KSON's signal into what now
remains of the tower.  See:
  John's report was edited and web posted by Gary Stigall.
This is the fine example of Gary's handiwork that we mentioned
  Q.  Was the removal of the bent-over section difficult?
  A.  Removal of the bent-over section was tricky business
because of the mechanical stresses involved and the danger of
wind gusts, but the operation was well planned and perfectly
executed by crews from Tower Structures, Inc. and Maxim Cranes.
  Q.  Did lightning have anything to do with the demise of the
KSON tower?
  A.  Presumably wind alone did the job, but lightning was
seen in the area and seemed to go hand-in-hand with the heavy
winds.  The following letter from Doug Shaw on December 30, 2004
is interesting:
  "I spoke to a lady who lived nearby who said [the tower] came
down about 2:00 a.m.  She said there were several lightning bolts
in the area, including one so bright she and her husband had to
shield their eyes.  They then went outside to look around and
saw the tower slowly bending over...."
  Doug can be reached at <douglas_e_shaw@hotmail.com>.
  Q.  Okay, so KSON is back on the air (as established by
John's web-posted report and confirmed by listening tests).
What about KURS and CH-17 that shared space on the tower?
  A.  We have no information to report on KURS, but CH-17 is
back on the air from Mt. San Miguel with temporary facilities.
  Q.  How much collateral damage occurred from the falling
  A.  Remember that very little of the tower actually fell
to the ground - only the top 60 or 70 foot chunk fell the night
of the calamity.  The big tower section that tilted over was
simply suspended in midair until it was cut free and removed
by a crane.  About six cars in the impound yard were damaged
by the falling 60 or 70 foot long chunk, but some of those
vehicles were already damaged by traffic accidents before
they reached the impound yard.
  There was only one report of damage off the impound lot
according to John Buffaloe:  That was a cracked windshield
caused by a flying bolt.
  All in all, there were no reported injuries or significant
damage to other structures, and that indeed is great news.
KSON is extremely lucky.
  Q.  Are there any new photos on the KFI situation?
  A.  Yes.  Steve Blodgett has added more pictures to his
web page.  The new photos show the KFI auxiliary tower that is
currently keeping the station on the air, including details on
the electrical "top loading" of that structure.  The real bonus,
however, is a set of black-and-white photos showing the main KFI
tower being erected.  Click to enlarge those photos and you just
might feel like you're a part of the action:
  Q.  Has any official information been published on the KFI
tower collapse?
  A.  Absolutely.  The National Transportation Safety Board
("NTSB") has published preliminary information on the aviation
accident that took KFI's main tower down:
  Q.  The web photos published so far have shown the
fallen tower, but what happened to the Cessna 182 aircraft
that brought the tower down?
  A.  NTSB investigators arrived on the scene almost
immediately after the accident and removed the aircraft remnants;
they reportedly cut a bit of tower metal where the wing had
imbedded itself - this to ensure that a proper study of the
collision could take place at a later date.  The airplane engine
apparently separated from the airframe in mid-air, and the engine
headed toward Coyote Creek.  According to one witness, the impact
crater is still visible although the engine has been removed.
  Q.  Is the KFI auxiliary tower an aeronautical hazard?
  A.  The KFI aux tower is located just a few hundred feet
from the base of the collapsed main tower.  Without a painted
and lighted main tower to serve as a protective structure, the
shorter unpainted and unlighted aux tower is of some concern.
Pilots are being advised of the "unlit" aux tower in a Notice to
Airmen.  We understand that a temporary solar powered beacon was
recently installed atop the aux structure.
  By the way, the technical parameters of the aux tower were
missing from the FCC's AM Query page until recently.  The
improperly archived file was converted back to active status
thanks to the efforts of Dale Bickel in Washington.
  Q.  Did lightning have anything to do with the demise of the
KFI tower?
  A.  In a peculiar sense, it did.  The aircraft that
brought the tower down was rented from "Lightning Aircraft Corp."
according to the FAA report cited above.  So, one could say that
the KFI tower was struck by lighting (again).
  Another curious thought - one that old timers will
immediately appreciate - was forwarded by Bill Lipis and
originated with an unnamed friend:
  "It occurs to me that with both 640 and 1240 out of
commission, Conelrad can't work.  Maybe there's some 
conspiracy that we don't know about."
