  DIGITAL TV LEGISLATION AIMS AT EDUCATING CONSUMERS
  Three capitol hill lawmakers have introduced legislation
aimed at stepping up the effort to inform the public of what
to expect when the DTV transition is completed in February 2009.
Among other goals, the bill seeks to force TV manufacturers to
label analog receivers with information about the transition,
require signs near analog retail displays, and direct the
FCC to undertake an outreach program to educate consumers.

  19,000 BROADCAST STATIONS ALLOWED TO ORIGINATE PROGRAMMING
  As of December 31, 2006, the FCC had licensed 27,807
broadcast stations.  Of these, 8,649 do not originate programming
(boosters and translators).  Therefore, the number of stations
that are allowed to originate programming is roughly 19,000
(same as the FM stereo pilot frequency expressed in Hertz,
so the number is easy to remember).

  RECEPTION RANGE OF THE 99.1 PIRATE
  When the 99.1 Oat Mountain pirate was on the air, I could
hear it in many places in the San Fernando Valley, on the drive

  THE L.A. AREA 87.9 MHZ PIRATE IS OFF THE AIR
  KKJZ [88.1 MHz serving the greater Los Angeles area] has

  COPPER THEFT CONTINUES, THIS TIME IN CATHEDRAL CITY
  I'm writing to notify those of you in SoCal that another copper
theft has occurred.  Our KNWQ (1140 kHz) site, located in North
Cathedral City, CA, near Palm Springs, had a portion of its ground
system stripped sometime over the weekend (Jan 27-28).  The
circumference of the entire site is fenced and there are also
fences around each of the 5 towers.  After slicing the fences with
bolt cutters, the copper mesh was lifted and cut, a trench around
the fences was dug and the majority of the radials for 2 towers
are gone.  We fully expect the culprits to come back for more,
since many of the radials were found coiled and ready to take
away.  We're checking our other two nearby AM sites this
afternoon.
  What's most disheartening is that while the ground system can
be rebuilt, we are unsure of what precautions to take to make sure
this doesn't happen again.  We are considering armed patrol
between our 4 local sites, more fencing and razor wire, and maybe
even changing to an above ground radial system.
  Last week, KNWQ's simulcast sister station, KNWZ (970 kHz)
in Coachella, CA was taken off the air when a vandal attempted to
cut the main feeder to the building after shutting off what they
thought was the main power.  (There are two disconnects to the
building.)  The bolt cutters were found still in the cable and
arcing.  We do not believe that the recent events are related.

  HOLD THE PRESS - KPSI(AM) GOT HIT FIRST
  Barry O'Connor of KPSI(AM), 920 kHz, Palm Springs, advises
CGC Communicator readers that every bit of copper at his 4-tower
transmitter plant disappeared just before the KNWQ incident.
At KPSI, it looked as if a vacuum cleaner with copper affinity
had gone through the array: All buried radial wires were pulled
out of the ground along with the 4" wide tower interconnecting
straps, and even on the towers themselves the copper wires were
stripped off.
  (Verbal report of January 30, 2007)
******************************************************************
  ONE POSSIBLE SOLUTION (EDITORIAL)
  Years ago, a Los Angeles AM station had its copper stolen.
They elected to replace the missing material, then added a clever
circuit.  Imagine a circle with a 50 or 75 foot radius around
each tower.  Now image that the circle represents a small diameter
copper wire that is laid practically on top of the radials, and
is also buried underground.  The idea is that when someone pulls
up a large diameter radial, the small diameter wire will break
and set off an alarm (in the studio in this case).
  Sure enough, late one night the alarm went off, but the
jock either chose to ignore it for some time or simply did not
understand what to do.  By the time the matter was sorted out, a
second ground system had disappeared.  This was back in the days
before alarm monitoring services were common.  But, the idea
could be resurrected.

  ULTRA-HDTV TO BE DISCUSSED AT NAB/LAS VEGAS
  NAB has announced that Hirokazu Nishiyama, managing director
of Japanese public broadcaster NHK, will provide the keynote
address for the 61st annual Broadcast Engineering Conference
at NAB2007 in Las Vegas, April 15.  Nishiyama will discuss new
broadcast services like mobile, HDTV, IPTV, and VOD and the
opportunities these advanced services create for broadcasters.
He will also discuss the various applications that make Ultra-
HDTV, which offers 16 times the resolution of current HDTV,
a promising technology for the future.

  INTERNET "RADIO" PRICES MAY FALL
  Wi-fi radio devices that link consumers to an exploding
number of Internet radio stations could become quite inexpensive
if a new chipset introduced at CES 2007 by Cambridge Consultants
pans out.  Based on just two ICs, Cambridge displayed a prototype
of its Iona Wi-fi portable radio which can be produced in volume
for around $15 in materials cost.
  By keeping parts count and cost low, Cambridge Consultants'
head of consumer products, Duncan Smith, believes that a complete,
stand-alone Wi-fi radio could be marketed in the $50 to $60
range...  Battery life from two standard AA cells is said
to exceed 15 hours...  But Cambridge isn't alone in its
new offering....

  MILLIMETER WAVES USED AS NON-LETHAL WEAPON
  A millimeter radio wave from a highly focused RF weapon was
shot from a large dish antenna mounted atop a Humvee in a recent
media demonstration of this evolving non-lethal weapon technology.
Anyone hit by the beam immediately jumped out of its path because
of the sudden blast of heat throughout the body.  While the 130-
degree heat was not painful, it was intense enough to make the
participants think their clothes were about to ignite.
  The millimeter weapon apparently targets only groups, not
individuals, and may go into production in 2010 or thereafter.
All branches of the military have expressed an interest in it
according to the published news release (see below).  This
indicates that the military is now far more interested in
non-lethal weapons than they were only a few years ago.

  BRAIN CANCER AND CELLPHONES
  A suggestion that long-term use of mobile phones may be
linked to brain tumors has emerged from an international study.
People who used a mobile phone for more than 10 years have a
39% higher than average risk of developing glioma, a type of
tumor, on the side of the head where they hold their handsets.
But the finding is said to be of "borderline statistical
significance," and other measures found no association between
mobile phone use and brain cancer.

  AMATEUR RADIO MORSE CODE TESTING ENDS FEBRUARY 23
  It's official.  On Friday, February 23, Morse code testing
will disappear from all Amateur Radio license examinations.
Currently, Technician class licenses are code-free, but the
February 23 change will make the General and Extra class
licenses the same way - allowing access to the HF spectrum.
  Publication of the new code-free rules in the January 24
Federal Register started the 30-day countdown for the new rules
to become effective.  Deletion of the Morse requirement is a
landmark in Amateur Radio history.

  MICROWAVING THE KITCHEN SPONGE - A FIRE HAZARD?
  Last week we mentioned a team of engineering researchers
at the University of Florida who "found that two minutes of
microwaving on full power killed or inactivated more than
99 percent of bacteria, viruses or parasites, as well as spores,
on a kitchen sponge."  Are there non-microwave-safe sponges
that will melt, ignite or otherwise be transformed when
microwaved?  The article did not say, so proceed with caution.
