  FCC BEGINS INQUIRY REGARDING BROADBAND OVER POWER LINES
  The FCC has launched an inquiry into the use of existing
power lines to send and receive broadband data - Internet by
carrier current as some old timers might call it.
  Two different Broadband over Power Line (BPL) techniques
are being considered.  "Access BPL" uses medium voltage (1,000
to 40,000 volt) power lines to bring Internet and other
broadband data to homes and offices. "In-House BPL" uses
existing electric utility wiring to network computers and
printers - as well as smart appliances - within a building.
  Today's chip sets for this application are capable of
generating RF out to at least 80 MHz using advanced modulation
techniques and high data rates.  The question of RFI - radio
frequency interference to authorized spectrum users - is an
important consideration.  We are entering uncharted territory.

******************************************************************
  COGNITIVE RADIO
  There is a movement underway at the Commission to increase
spectrum efficiency.  One way to do this is with radios and
antennas that could adapt to their operating environments by
automatically identifying vacant spectrum, switching to that
spectrum and carrying out a specific communications mission.
This is one example of "cognitive radio;" the U.S. military
already uses equipment like this.  Cognitive Radio is the
subject of an upcoming workshop at FCC headquarters.

******************************************************************
   FCC FORFEITURE WATCH - SELECTED ITEM
  The FCC has affirmed a $39,000 fine against KTCM(FM),
Kingman, Kansas, for operating a radio station from an
unauthorized location; failing to maintain prescribed obstruction
lighting on the antenna structure; failing to install and maintain
EAS equipment; failing to maintain a main studio at an authorized
location; and failing to maintain a public inspection file.
  The FCC's Enforcement Bureau has been instructed to do a
follow-up investigation to determine whether the licensee has
come into compliance and, if not, to take or recommend further
enforcement action as appropriate, including the possibility of
initiating a license revocation proceeding.

  UPDATED INFORMATION ON CORRECTING FCC'S PART 74 DATABASE
  The lead story in CGC #571 sent readers to a web posting that
quoted 1999 FCC text describing how to correct ULS errors in the
broadcast auxiliary database.  Those procedures are being changed.
  SBE is working with the Wireless Bureau to set up new procedures
that hopefully will use electronic filing since FCC Gettysburg has
limited staff to enter the information for changes in 6000
licenses in the ULS.
  We are asking licensees to wait until the new procedures are
in place before submitting any data.

  A NEW FOREST SERVICE PLAN RE RADIO INTERFERENCE DISPUTES
  The Cleveland National Forest office of the USDA Forest
Service has revised its plan for dealing with radio frequency
interference issues.  The following pdf file contains their
detailed plan (caution, the file is just over 1 Mb in size).
Comments are due on or about May 9 per our calculations.

  KFWB DAMAGED BY A MAJOR DWP SUBSTATION FAILURE
  As I pulled into the KFWB parking lot at 8:30 AM Wednesday
(April 23rd), the generator started up.  I knew that at the very
least, KFWB had lost utility power.  Flickering lights, beeping
things and a plume of smoke from an electrical panel confirmed
that we had real trouble.  The surge suppressors had taken a
fatal shot from a DWP substation explosion and fire, and KFWB
was about to go off the air!
  The series of events that followed made for a day to remember.

  HELPFUL ADVICE ON GUY ANCHOR INSPECTIONS (CGC #570)
  Over the years there have been numerous instances of towers
falling due to guy anchor failure, with guy wires hanging on to
as little as 1/4" of remaining shaft before failure.
  As a Tower Safety and Rescue trainer for our company, I have
taken trainees to a guyed tower to see the "point of daylight."
This is where the guy anchor meets the dirt, and is the most
likely place to reveal corrosion just below the surface, as shown
in the diagram of CGC #570.  Dig down about 6-12 inches and you
may likely find the beginnings of corrosion.  This inspection
should be performed regularly if you own a guyed tower.
  The best way to prevent or delay the corrosion process is
through the use of a "Sacrificial Anode" - or Cathodic Protection.
You can see the process of corrosion and how it can be prevented
in these instructional animations courtesy of www.anchorguard.com:

  LOOKING BACK AT KNOB(FM) ON SIGNAL HILL
  Helen Jones calls our attention to the following URL - an
engineer's flashback (1986-1990) to KNOB(FM), 97.9 MHz, Long
Beach, when it was owned and operated by Jack & Jeannette Banoczi.
Paul Sakrison was the engineer at the time, and Paul also prepared
the following web posting with pictures and words.
  One of Paul's comments: "....the air conditioning died and the
[transmitter] room got up to 170 degrees Fahrenheit.  It melted
the phone, but the transmitter was fine...."  See it all at:
  http://www.sakrison.com/radio/KNOB.html
  KNOB is now KLAX and the station has relocated its transmitter.

  Ric Tell has uncovered a gem of a URL: The Java Slide Rule.
Relive the days when slide rules ("slip sticks") were common
devices for doing multiplications, divisions and more complex
calculations.  This Java Slide Rule is fully functional, a work
of art, and apparently quite accurate.  Visit the following web
site to slip the stick and move the hairline bezel with your
mouse.  A high speed Internet connection is recommended.

  ANOTHER SPECTACULAR HUBBLE TELESCOPE IMAGE
  Resembling the fury of a raging sea, this astronomical image
shows a bubbly ocean of glowing hydrogen gas and small amounts of
other elements such as oxygen and sulfur.  The photograph, taken
by NASA's Hubble Space Telescope, is one of the truly memorable
photos worth downloading.  The image was released to commemorate
the 13th anniversary of Hubble's launch on April 24, 1990.

  TAKE TWO NANOCRYSTALS AND CALL ME IN THE MORNING
  Nanotechnology is a tiny world of magic that promises some
almost unbelievable advances, including applications in medical
therapies.  Northwestern University has released information about
a hybrid "nanodevice" composed of "nanocrystals" attached to
bits of DNA.  This Star-Trekish technology may one day be used
to target defective genes that play a role in cancer, neurological
disease and other conditions.

                      AMATEUR RADIO NOTE
******************************************************************
  6-METER SPLITS CLARIFIED (CGC #570, 571)
  There are several current band plans for 6-meters.  The
1.7 MHz split, with ODD numbered frequencies, is used in the
Pacific Northwest.  It is the band plan of choice by the Mid
America Coordination Council ("MACC") and is therefore used
in many states.  The 500 kHz plan, with its EVEN numbered
frequencies, is used in southern California and areas that
have adopted the SCRBBA/ARRL plan.  Still other areas continue
to operate with 1.0 MHz I/O spacing.

  CALL SIGNS GRANTED SOME TIME AGO - AND JUST NOW REPORTED
  The FCC has discovered a number of call sign changes that
  it had granted as far back as 12/27/02, but failed to report
  until now.  The grants are as follows:
  KSSC(FM), Santa Monica, to KDLD
  KSSD(FM), Newport Beach, to KDLE
  New(FM), Coachella, to KBXO
  KDFX-LP(TV), Indio/Palm Springs, to KDFX-CA
  K15EI(TV), Palm Springs, to KUNA-LP
  KKBE(FM), Ojai, to KFYV
  The callsign people probably feel much better having
  gotten that off their desks.
