  HIGH-SPEED CONNECTIONS TO INTERNET INCREASED 33% DURING
  SECOND HALF OF 2001
  High-speed lines connecting homes and businesses to the
Internet increased by 33% during the second half of 2001, from
9.6 million to 12.8 million lines, compared to a 36% increase
during the first half of 2001.

  90 MHZ OF SPECTRUM FOR 3G AND COUNTING
  FCC Chairman Powell expressed his gratitude that 90 MHz
of prime spectrum can be made available for advanced wireless
services (such as 3G) in the United States.  He also discussed
the recent success of adding 1710-1755 MHz to the advanced
wireless services spectrum pool.

  KFMB-DT TO INCREASE POWER
  [KFMB-DT's] Special Temporary Authority allowing a reduction
of power related to last year's regional energy crisis has finally
expired.  Starting August 17, KFMB-DT 55 (channel 8-1 on your set-
top box) will return to 703kW ERP, a gain of nearly ten times over
the present 78kW.  For now, we'll have the most DTV output power
in San Diego....

  THE MYSTERIOUS KXLU SCA REVEALED
  That was a correct assumption about the [KXLU] SCA usage on
July 4th, although I thought is was a 67 kHz modulation.  In
either case, it was firing cues for the pyrotechnicians on a
barge in Marina del Rey.
  I found some old SCA equipment in KXLU's storage and thought
it would be fun to try out.  In previous years, the audio for the
pyrotechnicians was routed through a phone line to a cell phone at
the firing location.  This year's SCA setup allowed for louder
EQed audio in enclosed headphones.  The pyro guy (Jeff Barker with
Pyro Spectaculars) felt it was a definite improvement.

  POWER MAKES THE PIRATE
  Q.  Where did you get the idea that the Ramsey FM-25 is a
pirate transmitter?  The Ramsey FM-25s that I have built put
out around 10 milliwatts....
  (TV Engineer, L.A.)
  A.  Let's do a little calculation.  FCC Rule 15.239(b) allows
a maximum field strength of 250 microvolts/meter at 3 meters for
unlicensed intentional radiators (wireless mics and the like)
operating in the FM broadcast band.
  If a half-wave dipole antenna were used, "back of the envelope"
calculations indicate that a maximum transmitter output power of
only 0.01 microwatts (0.00001 milliwatts) would be allowed.
(That's why FCC-compliant wireless mics in the FM broadcast band
cover almost no distance at all.)  So, 10 milliwatts is far too
much power to run, even if the antenna is seriously compromised.
  By the way, we never called Ramsey's FM-25 a pirate transmitter.
Rather, we questioned their statement that, "use of a device such
as the FM-25A kit MAY have some limited privileges in locally-
unused band space...."  That is a provocative and fascinating
legal question.    - Ed.

  SMALL STUDY LINKS CANCER TO VATICAN RADIO TRANSMISSIONS
  Following is a new study, but only one of many studies, that
epidemiologists and others will probably consider when revising
human exposure to RF emission standards:
  http://www.aje.oupjournals.org/cgi/content/abstract/155/12/1096
  RFR standard setting work is a difficult and somewhat subjective
process.  See CGC #448 for further information on Vatican Radio.

  CURIOUS EXPERIMENTAL GRANT
  Power companies have had a dream of delivering high speed
data along their utility lines, with wishful thinking that the
data signals would not leak into space (thereby causing
interference to over-the-air radio users, to say nothing of
receiving interference from those users).
  The following experimental grant might be along these lines
although the details are not readily available.  What is
interesting is the vast amount of HF spectrum that will be used.

  EXTRAORDINARY X-RAY FLARE
  Read about and see pictures of an extraordinarily powerful
class X4.8 solar x-ray flare which occurred at 00:35 UTC on
July 23 (8:35 pm EDT on 22 July), and whose effects may be felt
on earth for two weeks thereafter:

  The explosion produced a massive chromospheric and coronal
wave known as a Moreton wave.  Enjoy the photos even if you do
not have time to study the report.

  "BORDER RADIO" BOOK REVISED
  A revised edition of the book "Border Radio" is in print.
The book by Gene Fowler and Bill Crawford has the compelling
subtitle of "Quacks, Yodelers, Pitchmen, Psychics and Other
Amazing Broadcasters of the American Airwaves."  It covers "radio
outlaws" who operated superpower stations just south of the
Mexican border from the 1930s to the 1980s.  The new edition has
more photos and first-hand information, with an introduction by
the late Wolfman Jack.

  NEW DTV CHANNEL FOR ONTARIO
  The FCC has amended the Digital TV Table of Allotments for
  Ontario, CA, but we don't know how.  The underlying report is
  missing from the FCC's web site.
  The amendment probably has to do with KFTR's (formerly KHSC's)
  request to use DTV CH-29 instead of 47.  The following FCC Daily
  Digest will link to the underlying report when it becomes
  available:
