  NAB FINDS 13 OF 17 MINI-FM TRANSMITTERS VIOLATE PART 15
  A series of tests recently performed for the National
Association of Broadcasters (NAB) on 17 wireless FM modulator
devices (mini-FM transmitters) show that 13 of the devices
(76%) exceed the field strength limits set by the FCC.  Six
of those devices exceed the FCC field limit by 2,000%.  One
device transmits a signal that is 20,000% stronger than
allowed by law.
  Mini-FM transmitters are used by many consumers to transmit
audio from their satellite radios and MP3 or iPod players to
their in-dash car radios.  Many of the devices tested also
transmit signals that are substantially wider in bandwidth
than ordinary FM broadcast signals, resulting in potential
interference to first and second adjacent channel broadcast
stations.
  NAB has sent letters to both FCC Chairman Martin as well as
Senate Commerce Committee Chairman Ted Stevens and Co-Chairman
Daniel Inouye notifying them of these results.  The study's
author reminds readers that people or companies who sell non-
compliant equipment to users violate the FCC Part 2 marketing
rules "as well as Federal Law."  (The Technical Report linked
below is easy to read and worth a glance.  It includes
additional topics.)

  JUNE 23 STATUS REPORT ON MT. WILSON POWER UPGRADE
  "Just wanted to let everybody know that yesterday the
first customer transformer (feeding the Observatory and the old
'restaurant' area) was cutover from the old 4kV system at Mt.
Wilson to the new 16kV system.  The next one to go will be
CH-5 (KTLA) on Tuesday, June 27, followed by the backup service
to CH-11 & 13 on Thursday, June 29.  More info to come later
about what is on-deck for the days shortly after the Fourth
of July.

  FCC PROPOSED RULES FOR NEW BROADCASTING SATELLITE SERVICE
  The FCC has adopted a Notice of Proposed Rulemaking (NPRM)
seeking comment on licensing and service rules for satellites
authorized to provide service to the U.S. in the 17/24 GHz
Broadcasting Satellite Service (BSS).  The new service holds
the potential of bringing a new generation of satellite services
to American consumers,providing a mix of video, audio, data
and multimedia services to residential and business subscribers.

  FCC BECOMES ACTIVE IN BPL INTERFERENCE (FINALLY)
  The American Radio Relay League reports that the FCC Spectrum
Enforcement Division Chief Joseph Casey sent two strongly worded
letters to the city of Manassas, VA and its broadband over power
line (BPL) operator, COMTek, regarding a complaint filed by
amateur radio operator Dwight Agnew, AI4I, on January 19
concerning harmful BPL interference along a Virginia business
route.

the interference that can be experienced (per NAB) when third

  SETBACK FOR VENTURE TECHNOLOGIES
  The following FCC letter revokes the licenses for LPTV
stations K53IB and K59IB, Bakersfield, CA.  Both licenses were
issued to Venture Technologies Group, LLC.  Reason for the
revocation: The stations were apparently never built, and a
request for an investigation into whether Venture willfully,
knowingly and unlawfully made false certifications in the
dismissed license applications is pending before the
Enforcement Bureau.

  LPTV CH-6 IN NEW YORK, NEW YORK ALLEGEDLY BECOMES AN FM
  A verbal report indicates that WNYZ-LP, CH-6, New York,
New York has become an FM instead of a TV station.  There is
reportedly no visual carrier, but the aural carrier contains
a 19 kHz FM stereo pilot tone and the audio is grossly over-
modulated per TV standards.  TV CH-6 aural carriers are typically
centered on 87.75 MHz and can easily be received on many radios
by tuning to 87.7 MHz.
  If any of our readers can confirm or refute the technical
descriptions given above, let us know.  If anyone has specific
information on the aural ERP of WNYZ-LP, we'd like to know
that too.  Whether a TV station can legally convert itself into
an FM station is a high level question for FCC's Media Bureau
in Washington.
  As many of you know, Venture Technologies' KSFV-LP, CH-6,
on Mt. Harvard/Los Angeles has also been behaving like an FM
station for some time, although KSFV had a visual carrier on
the air last time checks were run.

  FCC FORFEITURE WATCH - SELECTED ITEM
  This NOUO (Notice of Unlicensed Operation) to an alleged
pirate broadcaster contains a wealth of interesting information
in a question and answer format.  For example, "Q: Well then,
if I am a low-power broadcaster and don't have an FCC license,
they [FCC Inspectors] need a search warrant, right?  A: Wrong
again....."  Interesting reading.

  PRECISION DTV FREQUENCY OFFSETS AND CLOCK JITTER
  Do you have a DTV station that must hold a precision
frequency offset (plus and minus 3 Hz) against the visual carrier
of a lower adjacent channel NTSC station?  Are you curious about
the term "clock jitter" even if you do not have a 3 Hz offset?
If so, this letter may help you improve the performance of your
DTV station.  (This is a longer-than-usual letter but one that
was invited by CGC because of the unusual issues involved.)

  FCC FORFEITURE WATCH - COMMENT
  Last week we mentioned that the FCC had issued a warning
to a Louisiana pirate who was allegedly broadcasting from the
antenna structure of former broadcast station KTRY-FM.
According to one seemingly well informed bulletin board post, the
"pirate" may be none other than the former licensee of KTRY who
simply "goofed up" when filing the last license renewal, and
was subsequently granted an STA to continue operating the station
for now.  
  Those interested can do a CDBS "Applications" search at the
URL below.  Enter the Call Sign "DKTRY-FM" (without the quotes)
and note the BLSTA item near the top of the resulting list -
that's the STA.  (The "D" in the call sign will bring up the
now deleted or "hidden" records for KTRY.)

  L.A. SHERIFF TESTING UNMANNED AERIAL VEHICLE
  A prototype drone called SkySeer is undergoing tests and
evaluation by the Los Angeles County Sheriff's Department as
a new tool to help in finding lost hikers, provide an aerial
view of fire zones, and perhaps assist in locating fleeing
suspects.  The small aircraft can be carried by one deputy,
assembled in minutes and then fly silently for 70 minutes
at speeds up to 30 MPH.
  One of the initial tests resulted in a crash of the
aircraft.  "There must have been some sort of communication
interference," the designer of the drone was quoted as saying
when inspecting the multicolored wires and circuitry spilling
out of the vehicle.

  RETURN OF THE PHONE BOOTH, WIRELESS STYLE
  Cellphones in public places are regarded by many as a
nuisance, and are almost impossible to use inside noisy
environments such as bars and restaurants.  But there may be
a trend afoot to ease the tension between users and non-users,
as some businesses install the latest in telephone booths:
a quiet place to carry on a wireless conversation without
bothering others.
