  SATELLITE RADIO INTERFERENCE TO BROADCAST SIGNALS - PART II
  The FM broadcast band is beginning to be hit by a new type
of "Part 15" radio frequency interference as explained below,
and the problem is destined to grow.
  CGC #722 discussed the mini FM transmitters that are built
into many XM & Sirius satellite receivers, and noted that our
office had received a few complaints where authorized FM signals
were being jammed out by the mini signals.  Howard Stern audio
was often mentioned as the culprit.  CGC #722 invited any and all
comments, especially those concerning whether the mini FM trans-
mitters were FCC Part 15 compliant (compliance would be suspect
if the mini FM signals could be heard for 100 feet or more on a
vacant FM channel).
  The URL below links to our readers' responses where a 
number of important points are made.  Since some of the Sirius 
receivers are capable of transmitting on 87.7 MHz, the matter
should be of interest to TV Channel 6 engineers as well (CH-6
aural carriers are close to 87.7).  Thanks to those who 
responded to our inquiry.  Here, now, are the details:

  LIFESPANS OF CD-Rs & CD-RWs - PART II
  Last week's quotation in CGC #722 from Kurt Gerecke, a
physicist and storage expert at IBM Deutschland, attracted quite
a few reader comments.  Most readers questioned his claim that
burn-your-own CDs would last only two to five years, as typified
by this response from an Orange County FM broadcaster:
  "About five years ago, there was an article in the Los
Angeles Times addressing this same subject, once again with an
expert saying the shelf life was short.  I e-mailed the reporter
telling her that we had audio CD-Rs that were 5 years old that
still reproduced good audio here at the radio station.  Those
CD-Rs were burned in 1995.  They still sound good in 2006...."
  Of course, the definition of disc failure is at the heart
of the matter.  A retired communications engineer who has looked
into archive quality CDs through a "little Googling" notes that
music CDs can play "pretty well" [or acceptably to some] with
uncorrected bit errors, whereas those same errors might be
catastrophic for other applications.
  For those interested in accelerated wear testing on
CDs, check out the first URL below, and note the outstanding
performance of "Silver+Gold, Phthalocyanine" CDs.  This paper,
from the Journal of Research of the National Institute of
Standards and Technology (Sept-Oct 2004), also indicates that
it is wise to store CDs in COOL/DARK/DRY places.
  In casting about the web, we discovered that that Kodak at one
time offered gold and gold/silver phthalocyanine CD-R discs - see
the second URL below.  However, several calls to Kodak and a
Kodak supplier indicate that these discs have been discontinued.
  The bottom line is this:  The only way to be reasonably safe
against both degradation and obsolescence is to copy your data
to the latest media every now and then, use redundancy, have
diversity in storage location and technology, and make
COOL/DARK/DRY a rule of thumb for storage.

  BONILLA CHAPTER XVI
  It appears that Broadcast Company of the Americas ("BCA")
has taken its September 29 pleading against Emmis Communications
- a pleading already dismissed by the Commission - and has filed
essentially the same highly distorted if not downright bogus
claims against Lazer Broadcasting.  This appears to be yet
another retaliatory action by BCA against the Lazer/Emmis camp
for Lazer's bold helicopter investigation of Mr. Bonilla's
Mexican broadcast operations, and the discovery of numerous
alleged engineering rule violations.
  BCA's Petition to Deny, and Lazer's response, are posted
at the URLs below.  The file sizes are 0.7 and 1.3 Meg
respectively.

  FOREFEITURE WATCH - FCC NABS THE CASTRO PEAK PIRATE
  KWVE, 107.9 MHz, San Clemente, has been receiving highly
intermittent but widespread co-channel interference from a pirate
that the FCC located near Castro Peak (seven miles WNW of Malibu).
The culprit had a habit of playing old radio dramas and assorted
other programs, perhaps for his own amusement.  We suspect that a
fairly powerful transmitter had been used at the outset, and that
the station was using reduced power when inspected by the FCC.
The pirate has been identified as John R. Burroughs, and the
FCC's Notice of Unlicensed Operation ("NOUO") issued to Mr.
Burroughs is available at the URL below:

  CALIFORNIA RACES TO COMPLETE AND SUBMIT DISASTER RESPONSE PLAN
  Last week, the State of California was rushing to submit
a comprehensive plan for dealing with catastrophic disasters.
The rush was to beat a federal deadline and establish eligibility
for a portion of the $2.5 billion to be doled out in homeland
security grants.
  State officials can't easily foresee a situation such as
occurred on the Gulf Coast where millions were evacuated from
the paths of Hurricanes Katrina and Rita, but admit that a nuclear
or biological event could hasten the need to quickly relocate a
significant number of people.

  CELL TOWERS CANNOT BE BANNED ON AESTHETIC GROUNDS ALONE
  This unanimous decision of the U.S. 9th Court of Appeals
is being hailed by wireless carriers anxious to build out their
networks, even if the proposed structures run cross-grain to
local aesthetic concerns.

  "Just an interesting note on the story about Joni Craig
and the pirate station [in San Diego] - use the following URL
and scroll down the page to see who is being sponsored by
Ms. Craig and [the San Diego] Foundation for Change.  Enjoy."

  "I thought you might find these pages interesting...."
Notice the links to the pirate stations on 96.9 and 106.9 MHz
in the right column.

  A REMINDER TO KEEP ROAD GATES LOCKED
  "Please remember that the gate nearest Sierra Peak should
always be locked.  We have had some reports recently reporting
that the gate has been left open.  Remember that keeping the gate
locked helps to protect your communications equipment.  Thank you
for your cooperation."
  Jolene McCall, Lands and Special Uses Clerk, USDA Forest Service
  (951)736-1811 ext 3235
  [Jake Rodriguez of the USDA Forest Service adds that the
gate on North Main that gives primary access to the peak is the
gate in question, not the gate on the spur road.  -Ed.]

  LIGHT EXPOSURE, NIGHT SHIFTS, AND THE DEVELOPMENT OF CANCER
  The following Web address goes to a Science News article that
many of you will find fascinating.  For years we have heard that
light exposure at night may play a role in the development of
cancer, as odd as that may seem.  The following article covers
light exposure, and much more.
