  SAN DIEGO BPL UPDATE
  May 10, 2005 - According to a representative of San
Diego Gas and Electric Company, SDG&E's plans for testing
Broadband over Power Line ("BPL") technology on a portion of
SDG&E's power grid are progressing smoothly.
  At least 30-days notice of the actual testing will be
provided to the public as required by Section 15.615 of the
FCC Rules.  The information that must be provided includes not
only the zip codes of the test zones, but the frequencies to be
used, the manufacturer and type of equipment to be used and the
proposed or actual date of the operation/s.
  The list of zip codes slated for testing is said to be
nearing completion.  SDG&E currently plans to release the
entire zip list all at once when the necessary bits and pieces
come together.  So far, we have no hint as to which geographic
areas will be tested.
  It is possible that SDG&E will test only one BPL system at
the outset and use only a small geographic area, but nothing is
definite.  SDG&E reemphasizes its willingness to work with all
potentially affected parties.

  FIBER OPTICS IN LIVE GAS LINES PROPOSED
  Website statement: "Sempra Fiber Links introduces a unique
solution to the last mile bottleneck for optic fiber networks.
  "We've developed a new and exciting process to safely route
fiber-optic cable and conduit to buildings through existing, live
natural gas pipelines.  That's right.  Active, live natural gas
pipelines.  So fiber-optic networks can easily go places difficult
to reach before.  Faster.  With less excavation and disruption."
  This web posting is of more than routine interest since Sempra
Fiber is owned by Sempra Energy which owns San Diego Gas and
Electric, the entity that will soon be testing BPL in San Diego.

  EMISSION MASK MEASUREMENTS FOR DTV TRANSMITTERS CLARIFIED
  The FCC has given some latitude for measurements of DTV
transmitter out-of-channel emissions.  For example, resolution
bandwidths of less than 500 kHz are now permitted in the
measuring equipment.  For details, see:
  http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-05-1321A1.doc
******************************************************************
  MORE 325(c) CROSS-BORDER PERMIT ACTIVITY
  More requests to send audio programming from U.S. studios
to Mexican AM & FM transmitter plants (so called "Section 325(c)
authority") have been filed with the Commission.  Here are the
latest applications, all for Jaime Bonilla stations, and all
filed in the name of Broadcast Company of the Americas, LLC:
  (a) For XHBCE-FM, 105.7 MHz, Class B, Matamoros Jaramillo
  (near Tecate), Mexico.  This is apparently the station that
  has been heard loud and clear in San Diego County as
  mentioned in earlier Communicators.
  (b) For XHBCE-FM, 105.7 MHz, Class C1, Tecate.  It is said
  that XHBCE, "holds authority to construct a new Class C1
  facility, and that the facility is yet to be coordinated.
  The instant application seeks authority to program XHBCE-FM
  upon coordination of the Class C1 facility."
  (c) For XEKTT-AM, 1700 kHz, Cerro Jaramillo.  This station
  is said to be in the process of moving to Tijuana.
  In other news, XHTIM, 91.7 MHz, Tijuana (apparently not a
Bonilla station) has been granted Section 325(c) cross-border
program transmission authority.  The complete FCC announcements
of all the items above are at the following URLs respectively,
and it is delightful to see the Commission publishing this
information for the public to view:

                           RANDOM NOTES
******************************************************************
  VATICAN CARDINAL AND PRIEST CONVICTED IN RFR CASE
  "A Roman Catholic cardinal and a priest in charge of
Vatican Radio have been convicted of polluting the atmosphere
with powerful electromagnetic waves" according to BBC News
World Edition.  Very interesting reading:
  http://news.bbc.co.uk/go/em/fr/-/2/hi/europe/4531247.stm
  or (same story)
  http://news.bbc.co.uk/2/hi/europe/4531247.stm
    and
  http://fullcoverage.yahoo.com/s/cpress/vatican_trial
  According to another news source, "Cardinal Roberto Tucci, who
headed the Vatican Radios management committee, and the station's
director-general, Father Pasquale Borgomeo, were given 10-day
suspended sentences and ordered to pay damages in the case,
Italian court officials said."  It is conceivable that the
alleged damages could run into the millions of dollars.
  "The case sprang from a medical report released in 2001 by a
public health agency that showed unusually high numbers of people
living near a forest of Vatican Radio antennas to the north of
Rome had contracted or died from leukemia."

  WHAT IS THIS GIZMO?  CGC COMMUNICATOR READERS REPLY
  The "strange and bizarre gizmo" pictured atop the tower
at http://earthsignals.com/add_CGC/050320_%20017_2.jpg and
discussed in last week's CGC Communicator newsletter is most
likely a lightning dissipation array.  That is the overwhelming
vote of our readers.  Just how does a lightning dissipation
array work?  Check out this remarkable video clip:
  http://www.lightningeliminators.com/das_systems.htm
  Now from Fred Vobbe: "You ask, "Will it survive ice and wind?"
Those of us in Canada and northern states just figure that once
in a while there might have to be repairs.  In my case, I have
found the stainless steel spikes from my array in the parking
lot, looking like someone detached them with a blow torch.
I would rather loose one of the 240 spikes than my RCA
transmitter or TFU30JA antenna!"
  Of the few readers who believe that the gizmo pictured
is an anti-perching device, one respondent wrote, "They have
them (bird anti-perchers) all over at LAX."  Lightning
dissipation arrays and anti-perching devices can look a lot
alike; someone will probably market a dual-purpose device soon.

  HOT SATELLITE PHOTOS
  Turns out that coordinates can be entered into the Google
Maps site <http://maps.google.com/> in either a degrees-minutes-
seconds format or a decimal degrees format, and our readers
correctly noted that using NAD-27 style coordinates (directly
from the FCC) isn't a problem when you are looking for something
as large as an AM directional array.  Here, then, are a number of
"Hot Coordinates" submitted by CGC Communicator readers in
response to our request last week:
  39° 50' 36.00" N 104° 57' 14.00" W
  Transmitter site of KLZ Denver, where the call letters
  are displayed on the ground and visible in the photo.
  - Kent Randles
  37.547n, 122.234w
  This is the KNBR site in Redwood City, California.  In the
  photo, you can see the main and aux towers, the unusual HAZ
  aircraft warning signs, the foundation of the tower that (along
  with the remaining aux tower) supported the original T antenna,
  and the ruins of shortwave station KGEI on the property to
  the east.
  - Erick Steinberg, KFOG-KNBR-KTCT-KSAN
  45° 29' 20.00" N 122° 41' 40.00" W
  The Stonehenge Tower, Portland, OR,  Seven FM stations
  combined.  Self-supporters show up well!
  - Kent Randles
  45° 27' 13.00" N 122° 32' 45.00" W
  Salem's hilltop three-self-supporter array of 1330 KKPZ
  Portland, with Disney's 1640 KDZR diplexed into the west
  tower.  The center tower is 212 degrees at 1330, and has
  the 7-bay pylon-mounted former main and now backup site
  for Infinity's 98.7 KUPL.

******************************************************************
  ABOUT THE PI-4100
   CGC #685 mentioned Potomac Instruments' new PI-4100 AM field
strength meter on display at <http://www.pi-usa.com/4100.htm>.
You might visit the web site, click on the words "Voltmeter
Display" near the top of the page and note that a whopping
2.264 V @ 12.405 km is shown.
  One of our readers observes, "The inverse distance field
has to be at least 28 V/m.... so this flamethrower would be
running near 6000 kW.  At that power level, who needs a field
meter, the fillings in your teeth should work as a nice detector!"
Perhaps the folks living near Vatican Radio are thinking the
same thing about now.
******************************************************************
  KOGO, 600 KHZ, SAN DIEGO, EXPERIMENTS WITH HD RADIO
  KOGO has been observed testing IBOC (HD Radio) over the air,
at least for a short period of time on May 11, 2005 according
to two reports that have reached our office.  One comment said,
"Both 590 KTIE and 610 KAVL signals were blanked by the [HD Radio]
sideband noise."  The other comment said, in effect, "So.... how
do I receive KTIE, that transmits from San Bernardino, in my
home in El Cajon during the daytime?
  As CGC Communicator readers know, HD Radio is a great
way for major market stations to eliminate out of town
competition, as this example clearly shows, although the
jamming aspect was not part of the original IBOC design.  If AM
HD Radio is eventually authorized at night, the jamming will
simply become full time.
  Had the original AM IBOC system included sideband energy
that would jam first adjacent channel stations, we are confident
that the product would have never seen the light of day, or the
dark of night.  Welcome to the new world of AM.
******************************************************************
  KKSB CALL SIGN CONFUSION EXPLAINED
  Two letters were received clearing up the sequence of
events that made it appear (incorrectly) in an FCC Public
Notice that the call sign "KKSB" had been assigned to two FM
stations at the same time.  A carefully orchestrated daisy-
chain of call changes avoided that snafu.
  Bottom line: The call sign "KKSB" is currently unassigned
for AM, FM and TV anywhere in the U.S.  According to J. D.
Strahler, "The KKSB call has been on many stations in Santa
Barbara, including 990 AM, 1290 AM, 97.5, 106.3, and last 103.3,
that I can recall."  Sounds like the market is giving KKSB a
well deserved rest.
******************************************************************
  EXTREME GEOMAGNETIC STORM OBSERVED
  A solar flare caused an extreme geomagnetic storm on earth
Sunday morning, May 15.  The storm measured 9 on a scale of
0-9.  For a discussion of possible power grid, satellite and
communications effects, see:
  http://www.noaanews.noaa.gov/stories2005/s2437.htm
******************************************************************
  DIRECT-TO-BRAIN BROADCASTING?
  Sony has developed and patented a new technology for
transmitting sensory data directly into the human brain.
According to an article in the New Scientist journal, the "non-
invasive" technique involves a device that fires pulses of
ultrasound at the head to modify synaptic firing patterns in
targeted parts of the brain, creating "sensory experiences"
ranging from moving images to tastes and sounds.
  Sony first submitted a patent application for the ultrasound
method in 2000, which was granted in March 2003.  Since then,
Sony has filed a series of continuations, most recently in
December 2004.  Sony describes the research as speculative.

  TECHNOLOGICAL PROGRESS
  As I sit here in Kuwait reading CGC #685, I am struck by
how our industry has progressed since the first Gulf War just
15 years ago.  Consider the equipment/cubage/man power/cost
requirements for an ISDN-quality radio broadcast live from that
conflict.  Now contrast that with the uplink/ISDN codec package
we have been using for the past week in Iraq that easily fits
into an airline-compliant carry-on bag with room to spare for
audio recorders, microphones, satellite phones, etc., all set
up and operated by a single person.
  I wonder what the next ten years or so will bring....

  HOLD THE LETTERS PLEASE
  CGC knowingly opened the floodgates by asking for letters on
two subjects that appeared in last week's Communicator - and we
received a wealth of terrific responses.  Thanks for the input.
  Reluctantly, we must now close the Letters to the Editor
department once again.  CGC is primarily a consulting radio
engineering firm, our newsletter readership has expanded
considerably, and we do not have the resources to deal with
a large amount of incoming mail.
  Of course, personal notes of all kinds that do not require
responses are always welcome.  Have a great story idea?  Post
you letters or stories on the web - or have someone do that for
you - and send us the URL so we can share your good works with
others.  Thanks!  - Ed.
