  FCC POSTPONES UPPER 700 MHZ AUCTION UNTIL 1/14/03,
  LOWER 700 MHZ AUCTION SCHEDULED TO PROCEED ON 6/19/02
  The FCC has postponed until January 14, 2003 the auction of
spectrum licenses for the 747-762 and 777-792 MHz bands (TV
Channels 60-62 and 65-67).  However, the auction for spectrum
licenses on the 698-746 MHz band "will proceed as scheduled
beginning on June 19, 2002."  The latter affects TV Channels
52-59.

  SERVICE RULES ADOPTED FOR THE GOVERNMENT TRANSFER SPECTRUM
  The FCC's Report & Order ("R&O") is now available on the
27 MHz of spectrum recently transferred from government to non-
government use.  (As mentioned last week, the 27 MHz consists of
chunks of spectrum in the 216-2390 MHz range.)  The R&O is 120
pages long.

  MICROWAVE RADOMES PROPOSED FOR LOCAL FOREST SERVICE SITES
  The Forest Service, in response to an environmental lawsuit,
is proposing to require radomes on all microwave dishes that
occupy local Forest Service sites.  The Forest Service maintains
that this action is necessary to protect the California Condor
from perching on the horizontal feed horns of the dishes and
becoming affected, perhaps even killed, by microwave signals.
  The local communications industry needs to work closely
with Forest Service officials to determine if there is enough
evidence to warrant protective action and, if so, to present
technical viewpoints before regulations are prepared.  One such
letter has already been sent to the Forest Service and is posted
on the web:

  RE STEALTH CELL TOWERS
  Just a quick note for those in the LA area.  In one of the
more imaginative disguises of a cell tower, I'd point out the
three very thick flagpoles that are nestled within the SR-134
and SR-2 interchange in Glendale.  Hidden inside the flagpole
are several cellular arrays, or at least that's what it looks
like to me!  The poles are directly on your left and just about
eye level as you make the transition from the eastbound 134 to
the northbound 2.

  MORE ON ERI'S TOM SILLIMAN
  The fascination with Tom Silliman's position and hands-on
insistence continues.  After Ripley's Believe It or Not, 20/20
and National Geographic (video & magazine), the Discovery Channel
has now picked up his unique and unusual trail.
  June 14 at 9 PM ET, The Discovery Channel will profile Tom
and his involvement with the Nashville Tower Project.  There will
also be a video tour of the ERI plant in Chandler, IN.

  SPECIFY ZIP CODE, GET LIST OF FM BROADCAST SIGNALS
  Here is a fun and free U.S.-wide tool provided by V-Soft
Communications.  Specify a 5-digit Zip Code and find out what
FM stations are likely to be received at that location.  The tool
uses the FCC's F(50,50) propagation algorithm and the receiver
coordinates are usually those of the local U.S. Post Office.
If a station is directional, its pattern is taken into account:

  CONDUCTIVE CONCRETE TOWER BASES POSSIBLE
  In rocky areas, it is often difficult to ground radio towers,
so conductive concrete bases may be the solution.  An apparently
practical conductive concrete was recently developed where a
substance known as coke breeze serves as the conductor (see
<http://www.chinacoke.com/brcoke.cfm>).  Use of the substance
for effective tower grounding is still speculative, however.
  We know that conductive concrete can be used as an electric
heater to melt snow and ice; that application has been tested on
walkways.  If a low voltage is applied, it is believed that
electrolysis and corrosion of steel reinforcing bars inside the
concrete will be prevented or significantly slowed.
  Perhaps entire rooms will be built of conductive concrete
someday.  The new material could serve as an electromagnetic
shield, preventing spies from intercepting computer murmurings.

  TRACKING HAM RADIO HF BEACONS IN YOUR LIVING ROOM
  One of the inventions that caught the eye of amateur radio
operators at this year's Dayton Hamvention was a high frequency
beacon network receiver that is so pretty it would be as much at
home in your living room as in your ham shack.  Not only that, it
lights up a LED on a map to show what beacons are coming in.
Martin Jue, K5FLU, of MFJ Electronics explains:
  "The beacons are precisely timed...so everything is exactly
right.  What we did was to duplicate that timing sequence in here.
And we make sure that it is always right because we have an atomic
clock receiver in here."

  SOUTHERN CALIFORNIA HAM RADIO REPEATER LIST
  The following list, courtesy of the Jet Propulsion Laboratory
Amateur Radio Club, covers 6-meter, 2-meter and 440 MHz machines.
While some repeater owners have opted out of having their
frequencies listed, the information is still very useful:
