  FCC FAVORS CREATION OF LOW POWER FM BROADCAST SERVICE

  As announced in CGC #306, the FCC is looking toward the
creation of a Low Power FM (LPFM) broadcast service.  The entire
proceeding is known as Docket 95-25.  You may view the FCC's own
press release at this address:

  FM TRANSLATORS TO AIR PUBLIC SERVICE ANNOUNCEMENTS?

  James H. Facer has filed a Petition for Rule Making to
allow FM translator stations to originate PSAs limited to no
more than 30 seconds per hour.  Interested parties may file
comments by March 12, 1999.  Further information is at:

  NEW TYPE OF RADAR RELIES ON BROADCAST SIGNALS

  Traditional radar operates by transmitting a brief radio-
frequency pulse from an antenna, then switching the same antenna
into the receiving mode to await return echoes.

  A new type of radar, Lockheed Martin's Silent Sentry, does not
transmit a signal at all.  Instead, it uses FM and TV broadcast
signals as the power sources.  The new radar simply senses the
backscatter from passing aircraft.

  The obvious advantage of the system is that it's operation is
undetectable.  Furthermore, since the transmitting stations are
located some distance away, "odd angle illumination" makes signal
reflection off stealth aircraft possible.

  To read more, see Popular Science, February 1999, page 27, and:

http://silentsentry.external.lmco.com/proj/nonsecure/sentry/SShome.htm 

  Saddam will want many of these "environmentally-friendly"
radar systems right away.  And his FM and TV broadcast engineers
will want hazardous duty pay.

  SIMPLEX REPEATERS FROM RADIO SHACK

  Regarding the story in CGC #304 on the simplex repeater
offered by Radio Shack (RS), the unit is so new that not all
stores are familiar with it.  Here's what I have learned so far:

  For $99.99 you can buy the RS 19-345 as a stand-alone simplex
repeater - it's the size of a half pack of smokes.  Records up to
30 sec. of conversation, then dumps it back.... can be used only
with radios that have a keying jack (PTT) and an earphone jack....
seems to work with most HT's rather easily.

  There is also some kind of simplex autopatch available for $150.

  LOS ANGELES EAS RMT:  A FAIRLY GOOD SUCCESS

  Richard Rudman reports that the January RMT for LA County
was originated properly by the Sheriffs Department.  However, some
users complained of "upcut audio" (the first syllable of the first
word of Sheriff Baka's message was missing at KAZN radio, for
example.)  Richard believes that the audio leaving the Sheriffs
Department was okay, and is investigating.

  The very fact that the Sheriff originated a successful RMT
gave EAS users a breathing spell to discuss another major system
problem: time clock drift.  The next story has the details.

******************************************************************

  TIME CLOCK DRIFT JEOPARDIZES EAS

  The subject of unacceptable time clock drift is now being
discussed on the LA EAS list server.  It seems that many of the
clocks built into our EAS decoder/encoder boxes drift wildly.
Even when the clocks are supposedly synced to the AC line,
large time variations often occur.  (Chris Hays suggests that
the clocks may be counting line noise instead of pure 60 Hz.)

  There are exotic ways to automatically sync EAS time clocks
(see <http://sbe36.org/eas/tips.html>) and then there is the
"McDonald's way."  As Jeff Staigh of Univision put it:

  "What just amazes me about this whole thread here is that
we've all paid several thousand dollars for a box whose primary
operation depends on the fact that its clock jives with its host,
and that host with the one before it.  Why can I go to MacDonalds
and buy a Kids Value Meal with a free....digital watch that
doesn't come CLOSE to the time drift we all are seeing (in our
EAS equipment).

  "I think (the EAS equipment manufactures are) missing the boat
here with not coming up with a black box/external timebase that
plugs into the various EAS equipment.  It may be a limited market
but I'd gladly pay to keep this sucker within spec.  This whole
system is (was) designed - I thought - to be basically hands-off
automation."

  (CGC suggests that a high quality quartz oscillator with
a WWV/self-setting clock chip - all UPS driven - would make
excellent black box components.  -Ed.)

  CHARA TELESCOPES ARRIVE ON MT. WILSON

  Helicopters were scheduled to install six new telescope domes
on Mt. Wilson about a week ago.  When completed sometime in the
year 2000, the scopes will work together as an interferometer to
produce remarkably sharp photos.  The project is called CHARA:
Center for High Angular Resolution Astronomy.  The first pair of
scopes is scheduled to be operating in June.  Light rays from the
individual telescopes will come together in a beam synthesis
building.  The new scopes will complement the existing 100-inch
and 60-inch telescopes on Mount Wilson.

  Why Mt. Wilson?  According to the Los Angeles Times, the
stable air at Mt. Wilson provides some of the best "seeing" in
the world.  Ironically, this clear view is produced by the same
inversion layer that traps smog in the L.A. basin.  The layer
forms a high-pressure ceiling, keeping a lid on the muck while
diverting cool, clear sea air to the mountain top.  While light
pollution from below prevents Mt. Wilson instruments from peering
deep into the universe, the still, clear air produces the
sharpest images of individual stars anywhere.

  K6STI LEAVES THE SOFTWARE BUSINESS

  Software developer Brian Beezley, K6STI, has gone out of
business.  Beezley says he's dropping distribution and further
software development as a result of the piracy of his RITTY
radioteletype program...... "I've just had enough of it.  I'm
really quite disgusted and bitter," Beezley remarked.  "I hate
being stolen from."  He said his software business was his main
source of income, and he's not sure what he'll do next.  Beezley
had also developed five antenna programs, including the Yagi-
optimizing program YO.  He remains available only via his U.S.
Post Office address of 3532 Linda Vista Dr, San Marcos, CA 92069.
He no longer has e-mail.

  JOHN DeWITT, JR., DECEASED

  NASHVILLE, Tenn. - John DeWitt Jr., 92, who expanded the
frontiers of science by bouncing a radar signal off the moon
and back to Earth, has died, his family said Tuesday.  A pioneer
in the broadcast industry, DeWitt conceived the idea of bouncing
radar waves off the moon in 1940 as an amateur astronomer.

  His first attempt to obtain moon reflections came in an
unsuccessful try using a 138-Megahertz transmitter and receiver
that he had developed for WGN-Radio in Chicago while working as
an engineer.  On Jan. 25, 1946, after several evenings fiddling
with other radio gear, his military-sponsored group heard the
first reflections of radar waves from the moon, proving that
electromagnetic waves could penetrate the Earth's atmosphere.

  After the findings were confirmed by independent experts,
news reports put the feat in the same class as the development
of the atomic bomb.  Time magazine declared, "Man has finally
reached beyond his own planet."
