  "INTERFERENCE TEMPERATURE" APPROACH FOR INTERFERENCE MANAGEMENT
  The FCC has adopted a Notice of Inquiry and Notice of Proposed
Rulemaking that set forth and seek comments on a possible new way
to quantify and manage interference among different services.

  ABOUT NOAA WEATHER RADIO
  NOAA Weather Radio ("NWR") is a nationwide network of more
than 800 radio transmitters broadcasting continuous weather
information direct from a nearby National Weather Service office.
NWR is designed to carry National Weather Service warnings,
watches, forecasts and other hazard information 24 hours a day.
  Working with the FCC's Emergency Alert System, NWR is also
an "all hazards" radio network (provided its transmitters don't
fail when an emergency occurs - and exactly that happened on
Strawberry Peak in Oct/Nov 2003 as we shall see in a moment).
NWR also broadcasts warnings and post-event information for all
types of hazards - both natural (such as earthquakes) and=20
environmental (such as chemical releases or oil spills).
******************************************************************
  NOAA WEATHER RADIO UPDATE
  The following seven frequencies are used for NOAA Weather
Radio nationwide.  Here is where the transmitters are actually
located in our part of southern California (all frequencies=20
in MHz):
  162.400 - Mt. Woodson (San Diego).  Same frequency also
  used at Broadcast Peak (near Santa Barbara), and at a low-lying
  site near Coachella and the I-10 freeway (Imperial Valley).
  162.425 - Mt. Soledad (San Diego) at the Navy Site.  This
  is a new station activated October 29, 2003 to carry Marine
  Weather primarily, see note 1.
  162.450 - Silverado Site (Santa Ana Mountains, co-located
  with the doppler weather radar station).
  162.475 - Broadcast Peak (near Santa Barbara), carries Marine
  Weather primarily.
  162.500 - Strawberry Peak (near San Bernardino).  See Note 2.
  162.525 - Avalon (Catalina Island).  Marine weather primarily.
  Was initially on 162.500, but too much interference with
  Strawberry Peak occurred so the frequency was changed.  Is
  still incorrectly listed on 162.500 in some NOAA literature.
  See Note 3.
  162.550 - Mt. Lukens (moved from Mt. Wilson about a year ago).
  NOAA staff dealing with these stations on a regular basis
include Mike Lauderdale and Gary Strickland.  Mike can be reached
at (858) 675-8700 x260 and mailto: michael.lauderdale@noaa.gov,
while Gary is available at (805) 988-6615 x260 and
mailto: gary.strickland@noaa.gov.  For web-based information
on NOAA stations, see <http://www.nws.noaa.gov/nwr/>.
   ______
   Note 1:  Mt. Woodson will progressively reduce its Marine
Weather traffic now that a dedicated Marine Weather Station has
been established on Mt. Soledad.
   Note 2:  The Strawberry Peak transmitter went off the air
during the October 2003 wildfires, and the total outage lasted
about a week.  On November 3, NWS issued a bulletin that read
in part: "It has been determined that the transmitter has not
been destroyed but power and telephone lines to the site may
have been damaged or destroyed by the fire."  On November 4,
CGC verified for NOAA that Strawberry Peak was back in operation.
  Note 3:  Although well outside our area, it is interesting
to note that a new NOAA Marine Weather station was recently
activated at Hearst Castle on 162.525 MHz.

  SAN DIEGO MDS COMPANY - PETITION FOR RECONSIDERATION DENIED
  The FCC has denied San Diego MDS' Petition for Reconsideration
and dismissed SDMDS' STA request as moot.
  Background:  On April 1, 1991, San Diego MDS admitted to
having no customers but requested a renewal of its license based
on its claim that its transmitter was fully constructed and
periodically sent signals over the air.  SDMDS argued that the
Commission did not require "such licensees to have customers."
  The FCC rejected San Diego MDS's argument that the "periodic
broadcasting of signals" constituted service.  Indeed, it said
that having no customers was contrary to the Commission's goal
of efficient use of the spectrum.

  CPUC APPROVES GEOGRAPHIC SPLIT OF 909 AREA CODE
  The California Public Utilities Commission has voted to
split the Inland Empire's 909 area code.  The split line will
run more or less horizontally.  Those north of the line (e.g.
San Bernardino according to one report) will retain the 909 area
code; those south of the line (e.g. Riverside per the same report)
will be assigned a new area code: 951.
  The new 951 area code can be dialed on July 17, 2004.  The
new code must be dialed beginning October 30, 2004.

  IN RESPONSE TO FIRE RESISTANT ROOFING (CGC #603)
  There are indeed ways to construct buildings to make them less
susceptible to fire, and while roofing is a key factor it is by no
means the only one.  Transmitter buildings are frequently located
in high fire danger areas and should use fire resistant
construction throughout.  And, while fire suppression systems are
expensive, so is the loss of a building and its contents.  These
days, CO2 systems are the best option.  Less expensive is creating
"defensible space" around the structure.  A 50 foot perimeter with
fire-resistant weed barrier covered by pea gravel is relatively
inexpensive but effective.  I suspect that insurance companies
will increasingly demand inspections and retrofits to reinsure
existing structures in high-risk areas.

  MORE ON WANDERING AM TOWER IMPEDANCES WHEN TOWER
  SECTIONS CORRODE AND FAIL TO MAKE GOOD CONTACT (CGC #603)
  I recently read Roy Trumbull's account of an unstable AM
tower impedance.  I too had a similar experience shortly after
hiring on at KMO in Tacoma, WA in 1966.  I also noted that the PA
efficiency seemed to change from time to time, and there was this
other curious issue: a huge amount of DX mail.
  The tower was an old self-supporting Blaw-Knox four legged
critter with a zillion bolts just over 200 feet tall.  I supplied
a rigger with four rolls of bare #10 copper wire, each about 220
feet long, and had him go to the top of the tower to bond one end
of each roll to one of the bolts holding the beacon on the tower,
then go down each leg, bonding the wires to a bolt at each leg
section.
  By the time the fellow descended less than 100 feet, the base
and plate currents had undergone major changes.  When he got to
the bottom (you climbed them hot in those days), I brought the
four wires to the center of the tower and that became our new
feed point.  Not only did we get a healthy increase in ground
wave (forgot how much), but the DX mail was cut by 90%.

  SIRIUS' USE OF 88.5 IS INAPPROPRIATE FOR SEATTLE (CGC #603)
  Regarding the use of 88.5 for Sirius modulators in the Seattle
area, KPLU-FM, a fairly high-powered long-range public radio
station, serves the Seattle metro area.  I wonder if perhaps this
poorly-chosen modulator frequency was why the installers had to
use a setup that overrode the FM antenna connection.

******************************************************************
  NOT HAPPY WITH THE EAS SYSTEM (SEE "MELTDOWN" - CGC #603)
  In your comments about EAS problems you didn't mention KFRG(FM)
not sending the EOM tone on the latest monthly test. KLYY(FM) 97.5
broadcast KFRG audio for about ten minutes until we pulled the
power on our Sage unit.  Events like this are nothing new, and
further illustrate the continuing inadequacies of EAS.  The system
is sorely lacking, but now we are "stuck" with it!  There are
times when I wish we were still on EBS!

  VIEW THE FEDERAL RADIO MANUAL
  The NTIA Manual of Regulations & Procedures for Federal Radio
Frequency Management (May 2003 Edition) is a great publication
that has a ton of useful information.  The only drawback is that
it costs $342.00 new; however, it is available for viewing and
downloading at:

  CELL PHONES WILL POSSESS LOCATION-BASED BEHAVIOR
  According to a report on the NIST.gov website, your cell phone
may one day be able to adjust its behavior or call handling based
upon where it determines you are located.  Such phones could, for
example, advise you of the closest bank, dial the nearest emergency
specialist or automatically forward your calls while you're in a
conference room.  The NIST website carries many other interesting
stories too:
