  FCC'S POWELL PROMOTES A FREE MARKET TELECOM REVOLUTION
  The chairman of the FCC is sending out a message that the
migration to digital telecommunications will not falter, and
entrenched service providers such as telephone companies and
cable television providers can either join the party or suffer
the consequences.  In an interview with reporters and editors
from the San Jose Mercury News, Michael Powell shared a number
of personal views including this gem: "I have no problem if a
big and venerable company no longer exists tomorrow, as long
as that value is transferred somewhere else in the economy."

  FCC OPENS SMART RADIO PROCEEDING
  In light of the ever increasing demand for wireless
transmitters, the FCC has adopted a Notice of Proposed Rulemaking
and Order that sets forth proposals and seeks comments on the
uses and applications for "smart" radio systems.
  Smart radios have the ability to adapt their use of spectrum
to their environments.  For example, a smart radio system could
use geolocation and table lookups to determine whether certain
frequencies are candidates for use in a particular area.  Then,
those frequencies could be scanned, idle spectrum identified,
and the best frequencies and power levels selected for a
particular link.

******************************************************************
  RULES FOR 5.9 GHZ INTELLIGENT TRANSPORTATION ADOPTED
  The FCC has adopted service and licensing rules for the
5.9 GHz Band (5.850-5.925 GHz) for Dedicated Short-Range
Communications (DSRC) in the Intelligent Transportation Systems
(ITS) Radio Service.  DSRC systems will provide a limited-range,
wireless link to transfer information between vehicles traveling
at high speeds and roadside units or other vehicles.
  Some examples of short-range ITS applications include
intersection collision avoidance, work zone warnings, road
condition warnings, electronic toll collections, and electronic
payment for gas, fast food, or parking.

  COMPANY FINED $8,000 FOR FAILING TO PAINT TOWER CABLES
  The FCC has assessed an $8,000 fine against Tower Properties
of Florida, Inc. for having unpainted cables attached to their
tower structure - cables that precluded good visibility of the
orange and white aviation-painted structure.
  Section 17.50 of the FCC's Rules provides that antenna
structures that require painting (such as the one in question)
shall be cleaned or repainted as often as necessary to maintain
good visibility.  Further, as incorporated by reference,
"[a]lternate bands of aviation orange and white are normally
displayed on coaxial cable, conduits, and other cables attached
to the face of a tower."

******************************************************************
  ANOTHER RFR CITATION:  KTMN(FM), NEW MEXICO
  An FCC inspection in the above-cited case revealed that
KTMN's transmitting antenna, which was mounted on an observation
tower used by the USDA Forest Service to watch for wildfires, was
mounted substantially lower on the tower than authorized in KTMN's
license.  Measurements taken by the FCC showed that operation of
the KTMN transmitting antenna at only 40% of its authorized power
created RFR fields which exceeded the public RFR exposure limit
by more than 300% on the observation tower and in areas outside
the fence surrounding the tower that were publicly accessible.

  A TOWER CLIMBER'S SAFETY HARNESS CAN KILL AFTER IT SAVES
  This authoritative government web site will open your eyes
to an unimaginable problem with riggers' safety harnesses.  The
very devices designed to arrest a fall can kill a climber in a
matter of minutes due to a curious phenomenon called "suspension
trauma" that has nothing to do with the jerk force exerted by
the arrest itself.  Discover the details at:

  WILL THIS VARIATION ON BPL ALLEVIATE INTERFERENCE CONCERNS?
  This interesting article from the "TV Technology" web site
suggests that a new, higher speed transmission system using the
microwave spectrum rather than HF, could indeed be an appropriate
response to worries about anticipated interference to HF from
Broadband over Power Line ("BPL") operations.  And, if you think
that microwaves cannot be transmitted over power lines, you might
be surprised.  Check out the story at:

  THE XEKTT MOVE FROM 550 TO 560 HELPS SOME, HURTS OTHERS
  The CGC Communicator has received a number of emails
regarding XEKTT's move from 550 to 560 kHz (see CGC #605-7).
It looks like the earlier interference woes (with XEKTT on 550)
have simply moved up the dial a notch.  One writer to laradio.com
reports that interference has been heard as far north as Great
Falls, Montana, to station KMON on 560.  Here are some other
comments:
  -----
  "...There have been complaints from San Diego - interference
with KLAC - to as far as Oregon - interfering with KSFO."
  John Unrath, mailto: jhunrath@raytheon.com
  -----
  "KSFO in San Francisco is reporting severe night time
co-channel interference."
  Bill Ruck, mailto: ruck@lns.com
  -----
  "KSFO on 560 has been receiving calls from listeners,
reporting severe nighttime interference from a Spanish language
station.  I have confirmed these reports, and have heard a strong
signal on 560 kHz, co-channel with KSFO, programming ballads and
easy listening - heavy orchestral arrangements - in Spanish, and
with no voice announcements."
  Art Leberman, mailto: artleb@earthlink.net
******************************************************************
  NEW TV SCREENS CAUSE INTERFERENCE TO AM RECEPTION (CGC #607)
  Emails on plasma and LCD TV screens suggest that there
could indeed be a serious radio frequency interference [RFI]
problem caused by these screens, as shown below:
  -----
  "I can confirm the [RFI] issue.  My wife and I bought a 42-
inch plasma and I have to shut it off completely to hear AM in my
home.  The monitor is great and the reception of the signals over
the air of KPBS-DT is worth the price of admission.  But when I
come home, I can "hear" that the set [is] on while in the driveway
and listening to the car radio."
  Christopher Carmichael, mailto: me@ChristopherCarmichael.net
  -----
  "If plasma TVs give AM listeners problems, what will they
do to the HF ham bands?"
  Neil McKie, mailto: n.mckie@bendcable.com
  -----
  "I have an LCD rear-screen projection HDTV at the house.
When I turn it on, it wipes out a perfectly good AM receiver in
an adjacent room!"
  Ron Russ, mailto: russ@ktwv.cbs.com
  -----
  [If you acquired a plasma or LCD TV from Santa this
  year and your AM reception has been affected, email us with
  your report.  Are LCD monitors equally problematic?

  SATELLITE HISTORY: SYNCOM I, II, & III - I WAS THERE (CGC #607)
  I was one of the US Navy folks at Kingsport during the entire
series of Syncom 1, 2 & 3 launches and tests.  I have audio tapes
of the launches and phone calls between the Prime Minister of
Nigeria and President Kennedy, who were both assassinated not long
thereafter.
  Syncom 1 worked during its initial launch, but when they fired
the apogee rocket for geosynchronous orbit it exploded.  During
Syncom 2's launch, there was no equatorial correction, so it had
a 22 degree north-south ellipse in a 24-hour period.  With the
corrections, Syncom 3 achieved near geosynchronous orbit.  My job
was range and range rate, parameters that are important for
maintaining geosynchronsity; too close [to the earth and the
satellite] would go faster than the earth's rotation; too high
and it would lag the earth's rotation.
  During the project, I met my wife in Florence, Italy and
courted her over Syncom II, probably the first time such a thing
was ever done.

  AMATEUR RADIO DISTANCE RECORD SET AT 241 GHZ
  Ham radio operators have a keen tradition of pushing
technology to its limits and setting new records of all sorts.
Now, another Extremely High Frequency ("EHF") distance record
has been set by the Virginia-based team of Brian Justin, WA1ZMS,
and Pete Lascell, W4WWQ.  The duo has stretched the 241 GHz record
to 38.4 miles (61.8 km) where severe atmospheric signal absorption
makes normal R-squared losses look trivial by comparison.  The new
distance record was set on Wednesday, December 3, 2003.
