  CONDUCTED EMISSIONS LIMITS BELOW 30 MHZ REVISITED
  The FCC has issued a Report & Order to modify the limits on
the amount of RF energy that is permitted to be conducted onto
alternating current (AC) power lines, per FCC Rule Parts 15
and 18.  The primary intent is to harmonize U.S. standards with
international standards.
  According to the FCC, "We observe that there is substantial
development under way of new broadband delivery systems that use
power line communication (PLC) technologies.  Pending the
development of worldwide standards for these new technologies in
home communication systems, and until we adopt new rules, our
existing requirements for carrier current systems will continue
to apply to these devices."

  FM PIRATE SILENCED IN PUERTO RICO
  The FCC has seized unlicensed FM broadcast radio equipment
operated by Mr. Amil Lugo-González in Jayuya, Puerto Rico.  The
Commission, on more than one occasion, had issued notices to Mr.
Lugo-González directing him to cease operation of the unlicensed
station.  The station had been broadcasting on 99.5 MHz.

  PARTIAL SOLAR ECLIPSE - MONDAY, JUNE 10, 2002
  Treat yourself to a partial solar eclipse (74% of the sun's
diameter covered, 80% of its area covered in San Diego) in the
late afternoon of Monday, June 10, 2002.  We here in the southwest
just happen to have the best seats anywhere in the U.S.
  In the Los Angeles/San Diego/San Bernardino triangle, solar
coverage will begin at 5:14 PM, reach maximum at 6:23 and end at
7:23 (all times are PDT, plus or minus a minute or two depending
on your exact location).
  For a list of precise eclipse times nationwide (add one hour
to the times shown for Daylight Savings Time), see:
http://sunearth.gsfc.nasa.gov/eclipse/ASE2002/ASE2002city1/ASE2002city1.html
  Obviously, looking directly at the sun without a special filter
is extremely dangerous and should never be attempted.  For
information on safe viewing including photography hints, see:
http://www.rhfleet.org/site/astronomy/soloareclipse.html
http://science.nasa.gov/headlines/y2002/03jun_sunset.htm?list713498
  Do you know anyone who will record the eclipse in the radio
frequency spectrum?  The sun generates lots of RF noise.  A strip
chart recording of the "RF eclipse" would be interesting.
******************************************************************
  CALL SIGN CHANGE GRANTED
  KXST(FM), 102.1 MHz, Encinitas, has changed its call sign
to KPRI.  As some of you may recall, KPRI was the call sign of
San Diego's 106.5 MHz facility in the 1970s, when it was operated
by Art & Ed Shadek.
  The call change should be officially announced in the next
FCC change list which is due out in a week or so.

  BIRDS NESTING BEHIND A MICROWAVE DISH
  Here is photographic evidence of a bird's nest constructed
BEHIND a microwave dish, well shielded from the radiating
feedhorn.  The following photos were taken by Dave Thomas, W6NSE,
at an Aeronautical Radio (ARINC) HF site on Long Island, NY.
  http://www.bext.com/_CGC/2002/birdnest.jpg
  Dave reports, "So far no problems making babies."
  Switching venues, he adds, "I contacted the head engineer
at KGO TV in San Francisco to see if they ever had any bird
problems at their 1200 foot Sutro tower.  He said the only bird
found dead near the tower was one in the parking lot that flew
into the side of a car...."

  THE JPL HAM REPEATER LIST IS UNOFFICIAL
  I must point out that [the JPL ham repeater frequency list
mentioned in CGC #516] is neither sanctioned nor approved by all
of the local coordination entities.  The list contains errors and
unauthorized information, and many 440 system owners have opted
out.  Some uncoordinated stations are listed giving them
unjustified and unwarranted apparent legitimacy.
  The ARRL repeater directory [not a web publication  -Ed.]
contains the listings the coordination entities recognize.

  RE STEALTH CELL TOWERS
  I believe Jim is correct on [the cell antennas disguised as
flagpoles at the eastbound 134 to northbound 2 intersection -
see CGC #516].  I passed by while these were under construction
and I had a chance to glance at the open panel on one of the
poles.  It looked like a cellular antenna to me.
  Also, the flag poles are much thicker than normal flag
poles.....  It will be interesting to see how well the flags
are maintained.

  THANK YOU
  Just a quick note to say that your bulletin is GREAT.  It has
a good balance and covers subjects that truly keep us up to date
on subjects we may otherwise miss.  In this last one, the concrete
with conductivity, the radomes for bird protection (we will have
to cook our own turkey this Thanksgiving), and other items are a
good balance.
  Thanks again, Hal Williams, Salem Communications

  OSHA FINES CONSTRUCTION FIRM IN CONNECTION WITH FATALITIES
  WASHINGTON - The Occupational Safety and Health Administration
("OSHA") has fined an Oklahoma construction firm $14,100 in
connection with the deaths of three men who fell from an Alltel
Corp. cell phone tower in Arkansas earlier this year.
  One of the men who died was the son of the man who runs the
small family-owned construction business.
  According to the article, the U.S. government says that
injuries and death in the telecom tower business are occurring
at a greater rate than in any other industrial sector.

  WLW(AM) INTERFERENCE PUZZLE SOLVED BY HAMS
  In what FCC Special Counsel for Enforcement Riley Hollingsworth
called "a textbook example" of FCC-American Radio Relay League
("ARRL") cooperation, a strange case of interference involving
power lines and Radio Station WLW, 700 kHz, Cincinnati, is coming
to a close.  It took a patient two-year investigation to trace
the primary problem to so-called static lines on 345 kV power
towers, lines that do not ordinarily carry electrical power.
  The static lines were not sufficiently RF-bonded to the tower
structures, but were loosely fitted into hanging brackets.  At
60 Hz, there's a reasonable ground contact.  At RF, it's a non-
linear junction.  ARRL Certificates of Merit were awarded to six
hams including Goeff Mendenhall, W8GNM, and Paul Jellison, WD8KMX
(Paul is Regional Engineering Manager for Clear Channel which
owns WLW).

  DE-ICING TECHNOLOGY USES RF
  A "new" de-icing technology for cars, airplanes, sidewalks,
etc. is claimed in the May 17 Kiplinger Letter.  Antennas
that are built into vehicles and pavements emit radio waves
that melt ice similar to the way microwaves defrost food.  It
is said that RF deicers will show up in some 2004 car models
courtesy of Ice Engineering.  All it takes is lots of power,
added weight and fundamental answers to human exposure to RF
concerns.

  IS HOLLYWOOD ATTEMPTING TO REGULATE A-TO-D CONVERTERS?
  A portion of Larry Bloomfield's editorial in the June 3
edition of Tech-Notes makes some rather astounding claims
concerning Hollywood's latest legislative attempts to gain
total control over copy protection.  He writes:
  "The Motion Picture Association of America.... filed the
"Content Protection Status Report" with the Senate Judiciary
Committee recently, laying out its plan to remake the technology
world to suit its own ends.  The report calls for regulation of
analog-to-digital converters (ADCs), generic computing components
found in scientific, medical and entertainment devices.  Under
its proposal, every ADC will be controlled by a "cop-chip" that
will shut it down if it is asked to assist in converting
copyrighted material -- your cellphone would refuse to transmit
your voice if you wandered too close to the copyrighted music
coming from your stereo...."
