  HOMELAND SECURITY - ITEMS TO BE DECIDED BY JUNE 18
  Leaders from the broadcast, cable and satellite industries are
considering a list of "best practices" recommendations to ensure
the effective delivery of emergency information through public
warning systems.  The 41-member committee is to complete voting
on specific recommendations by June 18, 2003.  One of the
questions to be decided is if "a single federal entity should
be responsible for public warning and all-hazard risk
communication."  Learn more at:

  FCC SCRAPS RELAXATION OF RF LIGHTING DEVICE EMISSION LIMITS
  AT 2400-2500 MHZ
  On June 9, 1999, the FCC adopted a First Report and Order that
relaxed the emission limits for RF lighting devices operating in
the 2.51-3.0 MHz band, but deferred to a future date action on
changes to the rules for RF lighting devices in the 2400-2500 MHz
band.  Now, with no apparent remaining interest by industry to
produce RF lighting devices in the 2400-2500 MHz band, the FCC has
decided to forego any further rule relaxations, at least for now.

  FCC FORFEITURE WATCH - SELECTED ITEM
  $10,000 forfeiture affirmed against John W. Ashley, dba
Ashley Communications, owner of an antenna structure in Dover,
FL, for failing to comply with prescribed antenna structure
lighting and/or marking requirements.

  SEARCHING FOR A SOLUTION TO LOS ANGELES' EAS WOES
  Why does Los Angeles seem to have recurring trouble with
its EAS RMTs?  In the following web posting, Burt Weiner shares
his views, Bob Gonsett asks Oscar Medina why San Diego's EAS is
relatively trouble free, and John Paoli (Los Angeles LAECC Chair
and Chief Engineer of KFI/KLAC/KXTA) responds to both postings.

  MEMORIES OF WIP(AM) AND THE EIFFEL TOWER (CGC #576)
  The photos in last week's Communicator were great!  Two features
brought back memories.  I grew up listening to WIP(AM) and I have
visited the Eiffel Tower many times, but never thought that the
Paris TV transmitters were in a below-ground vault near the base.
It is hard to believe that the giant structure was made of
sections of cast iron!  Many of Europe’s big cities locate their
TV antennas in very aesthetic towers (similar to the Toronto
tower) rather than in antenna farms.

  LATE CHANGES TO IBIQUITY SPOILED THE AUDIO (CGC #576)
   "...until about one year ago, the audio quality of Ibiquity
was excellent.  But, with the last software change to PAC
compression, it was apparent to me that the audio quality would
be offensive to the discerning listener.  Unfortunately, the
last-minute change in coding was a major step backward and may
doom consumer acceptance of the system.  It's too bad that so
many years and millions of dollars were spent in development only
to have the results spoiled at the eleventh hour."

  ANOTHER EXPERIMENTAL LICENSE DENIED
  The Commission has denied another FM experimental license.
The application details were never put online, but using the
FCC search [feature], I found that the mailing address for this
application was the same one used for the WC2XZV experimental
grant (CGC #551) that turned out to be an alleged Antelope Valley
FM Pirate (CGC #552).  That experimental license was eventually
canceled (CGC #558) due to violations of the terms of the grant.
  At around the same time frame of that last cancellation, in
January, an organization calling itself "Preservation of Urban
Music" filed for an experimental license on 99.1.  On May 21st,
the Experimental License Branch dismissed the application without
prejudice.  No reason was given in this brief dismissal letter:

  HEARING THE MAUNA LOA HAM BEACONS (CGC #576) FROM THE MAINLAND

worked Paul, KH6HME, on 2 meters using only my stealth Create
50-1200 MHz log periodic with 10W PEP SSB output from an old Icom
all-mode transceiver here in San Diego.

  CAN SPEEDING TICKETS BE OVERTURNED IF RADAR DEVICES ARE
  UNLICENSED? (CGC #576)
  Section 90.20(f)(4) of the FCC Rules provides that a "licensee
in [the Public Safety Radio Services] may operate radio units for
the purpose of determining distance, direction, speed or position
by means of a radiolocation device on any frequency available or
radiolocation purposes without additional authorization of the
Commission..."
  In other words, as long as the state had a valid license for
any Public Safety radio system, the radar guns are considered
licensed.
  If for some reason, some city, county, or state jurisdiction
did use a radar gun when they did not have a valid license in any
Public Safety service, the question of whether the reading would
be acceptable as evidence of a speeding violation is up to the
judge as a question of law, not a question of fact.  Most courts
would find that if it was unlicensed, the prosecution could not
use that reading as evidence of the speeding offense, but other
evidence - officer's observations, for instance - could be used
to establish the offense.

  TAMING THE TERAHERTZ
  There is a vast portion of the electromagnetic spectrum above
microwave, but below visible light (and infrared), known as the
Terahertz Gap (CGC #522).  Signals in this region, so called
t-rays, like x-rays, can see through many materials, including
clothing.  However, because t-rays involve non-ionizing radiation,
they are thought to be far less harmful than x-rays, or perhaps
completely harmless at low power densities.
  The following article, from M.I.T.'s Technology Review
magazine, outlines the state of the t-ray, and contains some
rather startling images.  T-rays seem destined to become the
next big thing in electromagnetics.

  JUST FOR FUN - SOMETHING TO STARE AT
  Hard day at the office?  Here's just the ticket!  Pour yourself
a refreshing beverage, sit back, relax, turn on a 440 Hz tone,
and click on the following link.  If the specified tone is
unavailable, it is permissible to substitute a tone of 1000 Hz.
