  FCC STUDY LOOKS AT UNLICENSED SPECTRUM
  Unlicensed transmitters trace their origins back to 1938, and
have been used recently by cordless phones, garage door openers
and product theft detectors, to name some popular devices.
  Currently, the market for unlicensed wireless devices is
experiencing unprecedented, double-digit growth, and is expected
to reach $5.2 billion in revenue by 2005 for wireless computer
networking alone.
  The following FCC White Paper highlights the importance of
unlicensed spectrum and advocates the need for more unlicensed
frequencies and FCC rule reform.  It also asks the interesting
question, "What happens when unlicensed devices start to provide
the same services as license-holders?"

  HD RADIOS STILL SET TO ROLL OUT THIS SUMMER - EDITORIAL
  Ibiquity Digital maintains the HD Radio receiver roll out
will begin as scheduled this summer, this despite the major
PAC codec algorithm setback disclosed in last week's CGC
Communicator and elsewhere.
  The PAC algorithm has been an ongoing puzzle for iBiquity.
Broadcasters were told at every recent NAB convention that all
parts of the HD Radio system were progressing well except for
some details with PAC, and we now understand that the current
PAC problems affect both AM and FM fidelity, not just AM alone.
  While the HD Radio system is said to be in good shape except
for PAC, that's like saying "the patient is in good shape except
for his lungs."  We wish iBiquity every success in resolving the
PAC problems soon.

  ANOTHER FAILED EMERGENCY ALERT TEST IN LOS ANGELES
  Los Angeles has had another failed Required Monthly Test
("RMT") of its EAS system due to encoding errors at the L.A.
County Sheriff's Department.  What is the solution?  This is
serious business, and your suggestions are needed.
  Following is one of several postings on yesterday's LA EAS
message board:
  "At 10:36 am. the county sent [Sheriff] Baca audio, no tones.
  "At 10:37 am. the county sent Baca audio with EOM, no header
  of two tone.
  "At 11:37 am. (over an hour late), the county sent a normal
  [RMT].  18 seconds of silence between the header and Baca.
  I had already written it off as a failed test and left it
  that way.
  "Why is it that they can't figure a way to [get it right]?"

postcards of KFSG at Angelus Temple (1938); the FCC's Grand
Island ("water cooled") Monitoring Station in Nebraska (1940);
and a QSL card from Gimbel Brother's WIP(AM), Philadelphia
(1924), signed by Richard Gimbel himself!

  EARLY TV RECEIVERS GOT BLASTED BY THE 15-METER HAM BAND
  The TV IF used to be 21.4 MHz.  When the 1947 Atlantic City
WARC allocated 21.0 - 21.45 MHz as the 15-meter amateur band
effective in 1951, the complaints of direct-pickup TVI became
horrendous.  As a result, in the mid 50s the industry shifted
the IF to 45 MHz (CGC #574, 575), thus alleviating problems from
the Ham Band, but inviting new problems in areas where there was
a land-mobile (e.g. police) system operating near that frequency.

  TURNABOUT IS FAIR PLAY
  I loved the Nevada Highway Patrol posting in CGC #575!  When I
realize how many tickets those officers issue, it seems to me that
turnabout is fair play, and the Commission ought to write THEM a
ticket for a change.  I'd love to hear the NVHP say "I didn't know
I needed a license, Officer!"
  Now I wonder if they licensed their radar guns - which they must
do!  If not, the validity of virtually every radar-based ticket
could be in question.  Interesting article!

  A SUCCESSOR TO CONELRAD WAS PLANNED FOR LONGWAVE IN THE U.S.
  The 640 and 1240 kHz CONELRAD symbols are long gone from AM
dials in the U.S., but did you know that a successor to the old
Civil Defense system was in the works, using longwave?  The plan
would have placed longwave receivers in every home and would have
employed ten LW stations to cover the 48 contiguous states.  For
a most interesting account, visit:

  THE AUTHORITATIVE SCOOP ON THE MAUNA LOA HAM BEACONS
  For an excellent overview of the famous Hawaiian amateur
radio beacons located on the slopes of the Mauna Loa volcano,
the following web page says it all!  CGC congratulates Paul D.
Lieb, KH6HME, for his years of operating the beacons and setting
world-class "VHF and above" distance records in the process.
If there is a DX opening, Paul will quit work (as an electrical
contractor) and make his way up to the Mauna Loa beacon building
for "hands on" DXing!

  CLAIM:  THE HONDA RUBE GOLDBERG IS NOT AN ANIMATION
  The Honda Rube Goldberg e-film mentioned in CGC #574 was
done with real components, and was not an animation, according
to an extensive posting referenced in Steve Bass's Home Office
Newsletter for May 21, 2003.  Supposedly six hundred six "takes"
were required to capture the one sequence where all of the
components worked perfectly, one after the other:
