  FREEZE ON FILING "MAXIMIZATION" APPLICATIONS ON CH-52 TO 59
  The Media Bureau has announced an immediate freeze on the
filing of "maximization applications" by analog and digital
television broadcast stations in the 698-746 MHz spectrum band,
currently comprising TV channels 52-59.  The freeze is said to
assist participants in a spectrum auction.

  MT. WILSON LAND GIVEAWAY PROPOSED
  WASHINGTON - A Republican congressman from rural Pennsylvania
has introduced legislation to give away 110 prime acres of
national forest around the Mt. Wilson Observatory to a science
institute....  U.S. Forest Service officials estimate the land is
worth $100 million.  But Rep. John E. Peterson is proposing to
give it to the Mt. Wilson Institute, the nonprofit group that took
over operation of the historic observatory in 1989 after it had
been closed for several years....  (Story by Chuck Neubauer,
Los Angeles Times.)

  LOS ANGELES EAS - ANOTHER MISSED OPPORTUNITY
  This morning's RMT went like this at ABC Radio:
  KFI RMT at 0431, received at 0434 with no Sheriff Baca (or
any other) audio.
  Civil Authority RMT from KNX at 0451, received at 0458.
KNX announcer says, "Well, we were expecting to hear from the
Sheriff, now with traffic, here's Chuck Rowe..."
  Sigh.

August 2 at a Holiday Inn in Burbank, CA.  Lunch is free.

  A SBE official adds that, "....both SBE Chapter 47 Los Angeles
as well as the local STE chapter here have been invited."  So,
it will hopefully be a popular event.  Good luck to all involved!

  COMMENT ON "STORED CARBON RESISTORS MAY CHANGE VALUES"
  Re the story in CGC #519, I've never found stored resistors to
change noticeably either.  I have seen many cases where carbon
resistors running near their limits go lower in value over time
and sometimes even avalanching to eventual dust.  I've also seen
big enamel wire wound resistors literally melt down to a puddle.

  RE MULTIPLE OWNERSHIP OF BROADCAST STATIONS
  Am I the only one who thinks this mass ownership of many
stations in any given market is wrong?  When "competing" stations
are under one giant conglomerate ownership, where is the
motivation toward excellence?  Personally, I think the old
'duopoly' rule made a lot more sense.
  Red Blanchard
  [Red is by no means alone in his thinking; we receive a few
letters each month along the same lines.  Even though the letters
are not published (because the CGC Communicator deals primarily
with engineering issues) all input is welcome.   -Ed.]

  MORE ON THAT "TUBE SOUND"
  Remembering the piece in CGC #518 about a motherboard with
a vacuum tube, here is a modern car stereo that also has "tube
sound."  It can play MP3 files as well!

  RF ABSORPTION (800 MHZ) BY TREES
  A colleague from AirTouch days (Tim O'Malley, IIRC) told of
a European study that showed eucalyptus trees to be the worst
RF absorbers by a good margin.  It was a proper study, not just
anecdotal evidence.
  I found the tamarisk, prevalent in the greater Palm Springs
area, to be a good absorber too.   And the State of Georgia is
famous in the cellular industry for its 800 MHz eating pine trees.
Seems the needles are about a quarter wave for cellular.

  COMMENT ON QUANTUM TELEPORTATION
  Who would have imagined that teleportation might someday
become a means of communication rather than transportation?
FYI, a claim of teleporting a quantum state has been circulating
since 1998:

Society writes: "I've borrowed the unit & have been able to
readily sort out and match the wavelengths of my various filters
and laser diodes.  I just placed an order for one of my own.
Playing with this device was just like getting my hands on my
first RF spectrum analyzer all over again.  What a world it opens
up when you have the tools to "see" what you're working with...."

  FALLBROOK AMATEUR RADIO "FIELD DAY" ACTIVITIES INCLUDED LASER
  June 22 - Members of the Fallbrook Amateur Radio Club near
San Diego, CA, participated in a laser CW (Morse code) contact as
part of their annual emergency communications drill known as Field
Day.  The contact took place over a three mile path and included a
measurement of the approximate half-power beam width of the
incoming laser beam sent by an ordinary over-the-counter red
pointer laser.  The half-power beam width at three miles was
estimated to be ten feet.

  INTERNET SPAM FILTERING
  Could the CGC Communicator be regarded as spam?  New software
called SpamAssassin thinks so, and some ISPs are installing that
product now.  The interpretation of spam has to do with the lines
of capital letters used in Communicator titles and especially in
the LOCAL ITEMS FROM THE FCC section.  SpamAssassin thinks we're
"shouting."
  If you have trouble receiving the CGC Communicator, let
your ISP know.  If there are unresolved problems, let us know.

  LARGELY-OPERATIONAL LINOTYPE MACHINE ON DISPLAY
  One fascinating attraction at this year's San Diego County
Fair (aka the Del Mar Fair) is a largely operational linotype
machine on display in the San Diego Union-Tribune area.  This
was one of several such machines used by the Union-Tribune until
1973, and was recovered from a storage area amidst a pile of
junk, then restored by a company employee.
  For more on linotypes, see:
  http://www.woodsidepress.com/LINOTYPE.HTML
  The linotype is a magnificent educational tool showing what
came between Gutenberg and computer typesetting.  Also on display
in the UT area is a large wooden cabinet containing a variety of
hand-set lead type from the pre-linotype era.  Enjoy!
