  NTSB RELEASES DETAILS ON THE KFI TOWER DISASTER
  On December 19, 2004, a Cessna 182P single engine airplane,
preparing to land at Fullerton Municipal Airport, collided with
the KFI(AM) tower in La Mirada, California.  The private pilot
and his only passenger were killed, and the tower collapsed
(CGC #664, 665, 666).  A sharp-eyed CGC Communicator reader
discovered that the NTSB has released details on the catastrophe,
and a few of the more interesting findings are as follows:
  o  When the airplane was about 3 miles north of the Fullerton
Airport, it was cleared to land there.  Shortly thereafter, an
Air Traffic Control Specialist "observed an explosion west of
the airport and watched as the KFI tower collapsed."
  o  A witness driving on I-5 is quoted as saying to his wife
seated next to him, "If that plane does not make a radical turn
he'll hit the...."  The sentence was apparently interrupted
midstream when the plane hit the tower about 15 feet from the
pinnacle.
  o  The Fullerton Air Traffic control tower was equipped
with a certified D-BRITE radar system.  An echo of the KFI tower
was illuminated on the screen that the controller monitors.
However, alerting pilots to possible collisions with fixed
obstructions is not a controller's primary responsibility, nor
was there information in the report suggesting that this
controller was even aware of the pending collision.
  o  The pilot in question had 188 hours of total flight
experience according to his flight logbook, with 103 hours
accrued in rotorcraft, and 85 hours accrued in fixed wing
airplanes.  The pilot accumulated a total of 4 hours in a
Cessna 182, completed in the accident airplane.
  o  Accident Research Laboratory performed toxicological
testing of specimens of the pilot.  Results of analysis of the
specimens were negative for volatiles and tested drugs.
  o  On January 24, 2002, the Fullerton airport manager
reported that he had spoken to the KFI engineer who had opted
not to install tower strobe lights regardless of a suggestion
made in the months prior.  However, strobe lights are not required
by FAA regulations for obstacles less than 1,000 feet AGL, such
as the KFI tower, in daytime conditions.
  o  In response to an e-mail survey of people who have had
experience within the Fullerton airspace and specifically with
the KFI transmission tower, "The second query stated that, prior
to the recent accident, did they think that the KFI tower was a
safety hazard to aircraft operations at Fullerton Airport?  In the
122 responses, 88 pilots answered "yes," 29 answered "no"...."

  LOJACK'S WAIVER REQUESTS - SOME GRANTED, SOME DENIED
  LoJack Corporation operates its nationwide stolen vehicle
tracking system on 173.075 MHz, a frequency that can cause
interference to the reception of TV Channel 7 (174-180 MHz).
For this reason, the FCC has limited mobile-unit transmissions
to either 200 milliseconds every ten seconds, or 1800 milliseconds
every 300 seconds, with a maximum of six messages in any thirty-
minute period.*
  Now, LoJack wants the Commission to abolish these limits,
but the FCC has refused to do so.  However, some of LoJack's
other waiver requests have been granted in whole or in part as
explained at the URL below.
  http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-05-3340A1.doc
 * Transmissions may be 200 milliseconds every second while a
vehicle is being actively tracked.

  UNBUILT WTB GRANTS TO BE AUTOMATICALLY TERMINATED
  WTB is the FCC's Wireless Telecommunications Bureau, and
this story concerns a software feature that will soon be
implemented in the Commission's ULS (Universal Licensing
System).  When the wireless radio service in question includes
construction or coverage requirements and the licensee fails
to submit a notice of construction or request for extension of
time as required, ULS will automatically notify the licensee
that its license, location or frequency has automatically been
terminated, and ULS will list the license, location or frequency
on a weekly public notice as automatically terminated.  Note
that WTB is not the same as the Media Bureau which licenses
primary broadcast stations, although broadcasters may use some
aux frequencies handled by WTB.

  "TALKING BILLBOARD" ON 1610 KHZ IN SAN DIEGO IS POWERFUL
  A new "talking billboard" on 1610 kHz is reportedly located
on the west side of I-805, just before the southbound Sorrento
Valley Road on-ramp.  It's said to be a tall billboard with an
eight foot whip on top.  It has been playing a 60 second BMW
spot for the past few weeks.  The problem is that the signal
is reportedly audible in El Cajon some 14 miles away.

  FEEDBACK ON "EXPANDED BAND" HD RADIO DISPLAY
  The CGC Communicator received a number of letters on Cox
Radio's survey of preferences for displaying HD Radio channels
with indications such as 108.1, 108.3 MHz, etc. - even though
these would be fictitious frequencies (see CGC #719).
  Suffice it to say that electrical engineers, having invented
a technology like HD Radio, often assume that someone else will
figure out how best to display channel numbers for consumers.
The same problem exists in the cellphone industry (and the HDTV
industry) where the human interface problem is not only
challenging, but is perhaps one of the most difficult tasks in
all of engineering.  Perhaps Human Interface Engineering should
be given more weight as a formal field of engineering endeavor.

  BPL LOCATOR BY ZIP CODE
  Following is the power industry's official website to
determine if there is a BPL (Broadband Over Powerline) system
operating in a given zip code.  Try, for example, zip 92123 to
see the limited details that are available on the first BPL
system being tested by San Diego Gas & Electric Company (SDG&E):
  http://www.bpldatabase.org/
  By the way, SDG&E plans to test other BPL systems, and
intends to geographically separate the systems from each other
to avoid inter-system interference.

  V-SOFT IMPROVES ZIP/SIGNAL PROGRAM
  V-Soft Communications has added hotlinks to their free
Zip/Signal program (signal strength at zip code centers) that
is available on the web.  Now, when you enter a zip code, the
program shows a hot-linked table of all the radio stations having
a signal strength above 50 dBu in that zip code.  Just click on
the hotlinks in the list to bring up the FCC's AM or FM Query
programs to find out details on any of the stations listed.
  Zip/Signal handles all licensed AM (day & night) and FM
stations in the U.S.  You can also look up a given station by
its call sign and see a complete sort-ordered list of the signal
strengths for the station organized by zip codes.  There is no
charge for using Zip/Signal.

  BASE JUMPER DANGLES FROM A GUY WIRE AT KOVR-TV, STOCKTON, CA

  PUBLIC SAFETY: CHALLENGES OF OPERABILITY AND INTEROPERABILITY
  First responders and public policy makers should understand
that interoperable radio systems are only as good as their
operability; when a natural disaster strikes and disables a
radio system, or the channel capacity is exceeded, or the
dispatcher is overwhelmed, even interdepartmental communications
fail.  More attention needs to be paid to ensuring that basic
communications remain available when the chips are down.

  EUROPEAN UNION LAUNCHES FIRST SATELLITE IN NEW NAVIGATION SYSTEM
 
  The U.S. Military will soon have at least two competitors
providing satellite-based navigation systems, and both promise
greater accuracy than the existing Global Positioning System.
The European Union recently successfully launched the first
satellite in its Galileo system, designed to pinpoint locations
within one yard, and Russia just added three new satellites to
its GLONASS constellation.
