  HOW TO OBTAIN A COPY OF THE 87.9 MHZ ERDS PETITION

  To obtain a copy of the Petition for Rulemaking requesting
that 87.9 MHz be made into a nationwide Emergency Radio Data
System channel (see CGC #349), visit:

  PRIMARY "CLASS A" STATUS PROPOSED FOR LPTV STATIONS

  The FCC has begun a rulemaking proceeding looking toward giving
certain low power TV stations primary Class A status.  But, as the
Commission itself recognizes, there is a basic problem in giving
these stations "primary status while also maintaining their
obligation not to interfere with existing broadcast and other
primary services," including stations making the DTV leap.

  For a synopsis of this seemingly contradictory proceeding:

  ADDRESSING THE PEAK-TO-AVERAGE POWER ISSUE OF OFDM MODULATION

  One argument against switching from 8-VSB to OFDM (or COFDM)
modulation for digital TV (DTV) is that larger transmitters would
be required since OFDM has a higher peak-to-average power
requirement.  Now, that issue has been addressed by Wang,
Tjhung and Ng in the September issue of IEEE Transactions on
Broadcasting (p. 303).  The authors present a companding
technique which reduces the peak-to-average power burden.

  OPTICAL FIBER NOW BEING INSTALLED AT 1,400 MILES PER HOUR

  One interesting way to understand just how fast optical fiber
cable is being installed in the United States is to express the
installation rate in terms of miles per hour.  Obviously, the
rate is an "arithmetic fiction" and will vary on any given day;
however, KMI Corp., Newport, RI (www.kmicorp.com), was kind
enough to provide Communicator readers with the following data:

  "KMI's research suggests that about 20 million km of cabled
fiber will be installed in the U.S. in calendar-99.  If you
divide 20 million km by 365, you get 55,000 fiber-km installed
per day; divided by 24, you get 2,300 fiber-km installed per hour.
Converting km to miles, you get about 1,400 miles per hour.  All
of this assumes that the 20 million km of installation is evenly
distributed throughout the year, with the same amount each day,
etc. ...."

  LOS ANGELES COUNTY WANTS ITS OWN 2 GHZ SPECTRUM

  Have you seen/posted anything on the request that LA county
has made for a declaratory ruling that they are "co-equal" with
broadcasters in the 2.5-2.58 GHz band?  They are tired of dealing
with broadcast coordination.....

  Anon.

  [We have seen and heard quite a bit.  CGC is now attempting
to obtain copies of the experimental authorization requests and
will consider posting that data on the web, along with other
information.  Meanwhile, SBE and SCFCC are said to be preparing
a formal written response to the FCC.  L.A. County has also
requested 2 GHz ham spectrum, and the ARRL has reportedly filed
an opposition to that request.   - Ed.]

  ANOTHER LESSON FROM THE L.A. EAS SYSTEM

  Today's RMT was originated on time by the Sheriff's Dept.
but had more than 30 seconds of noise preceding start of audio.
There was a shorter but no less noisy period after the audio
ended before the EOM went out.....

  The lesson here at KFWB is that least one of our Operators
needs reminding that the posted procedure calls for listening to
the entire message before attempting to (air it).....

EAS Required Monthly Test (RMT) - much more information than we
can publish here. For instructions on how to subscribe to the
free Los Angeles EAS list server, visit:

  THANKS!

  I have read your column for more than a year now and it's
time for me to say thank you for all the hard work you do.....
I am really enjoy reading the CGC Communicator.  It is very
informative and full of good info.

  I very much enjoy reading the newsletter.  I especially
appreciate the short format WITH URLS!  That truly is a service!
Being able to skip what doesn't matter to me, and get the
expanded story on stuff that does with a click, is fabulous!

  FCC ACTS ON 'TELECOM FOR PERSONS WITH DISABILITIES' ISSUE

  The FCC has issued a Report & Order and Further Notice
of Inquiry in the proceeding dealing with "Access to
Telecommunications Service, Telecommunications Equipment and
Customer Premises Equipment by Persons with Disabilities."

  While most of the issues deal with telephone-related
matters, some involve computers and the manner in which
broadcast signals are presented.  To read the whole enchilada,
(this is a very long item), see:

  9,000 YEAR OLD FLUTES DISCOVERED

  A letter in last week's Nature describes six ancient flutes
made from hollow bird bones, and only recently discovered.
Excavated in China, the instruments are almost 9,000 years old --
and one of them is still in good enough condition to be played.

  This flute is the oldest known complete playable musical
instrument in the world, has seven note holes and is 9.5 inches
long.  Analysis of the sounds from the instrument indicates
that a tiny hole drilled next to one of the primary holes
corrects a slightly off-pitch tone.

  AUTOMATED INSPIRATION

  Computers are performing increasingly complex tasks guided
by trial and error strategies inspired by Charles Darwin's theory
of evolution.  For example, "artificial evolutionary algorithms"
have created completely new antennas which look crumpled and
weird.  They resemble drinking straws bent into odd shapes, but
are in fact excellent radiators.  A fellow named Charles Linden
(Linden Innovation Research, Herndon, VA) has received a patent
on the new devices, possibly the first for an invention by a
non-human designer.

  This and many more amazing stories are published in Science
News for September 4, 1999 (Vol 156, No. 10), p. 156.  Computers
are showing us entirely new approaches to old problems by
providing 'automated inspiration.'

  BABY PANDA CAM - LIVE FROM THE SAN DIEGO ZOO

  A gold star goes to the web camera streaming live video of
the baby Panda at the San Diego Zoo.  The site works well
even with low speed (28.8 k) internet connections because the
Panda Team keeps the camera trained on the subject, using
close-ups, filling the screen with action.

  See:  http://www.camzone.com 

  and click on "Baby Panda Cam Live."
