  BPL: FCC ADOPTS MEMORANDUM OPINION AND ORDER
  The FCC has adopted a Memorandum Opinion & Order (MO&O)
promoting the roll out of Access Broadband over Power Line (BPL).
In so doing it has ruled on a number of interference issues, but
not necessarily in a manner that will please legacy users of the
spectrum.  For example, the FCC has denied a request from the TV
industry to exclude BPL from frequencies above 50 MHz.
  The FCC's press release (first URL below) explains the
main features of the BPL MO&O.  The full MO&O is at the second
URL.  The remaining web addresses link to short Statements from
FCC Commissioners.

  NPR TESTS SHOW SUBSTANTIAL NUMBER OF MINI FM TRANSMITTERS
  EXCEED FCC EMISSION LIMITS
  In a new study of FM modulators (mini FM transmitters)
using "real-world" test conditions, NPR Labs says the measured
field strengths of about one-third of the devices exceeds FCC
Part 15 emission limits according to Radio World.
  NPR Labs took measurements on more than 28,000 moving cars
on two channels, 87.9 and 88.1 MHz, and estimates that a driver
could pass dozens of FM modulators in an average commute.  The
lab found that nearly 1% of cars had operating FM modulators 
on these two channels.
  Of course, the use of 87.9 MHz is prohibited by FCC Rules
because it is inside TV Channel 6's spectrum (as is 87.7 MHz).
Mini transmitters using these frequencies should be removed
from the market, see second URL for the Rules being violated.

  MIKE STARLING SUGGESTS PUTTING ALL MINI TRANSMITTERS ON 87.9
  In order to remove interference to existing FM broadcast
stations, NPR's Mike Starling suggests one possible solution:
change the FCC Rules and put all mini transmitters on 87.9 MHz
(see URL below, third paragraph from the end).
  Mike is a consummate professional and a good friend, but CGC
respectfully disagrees with him on this issue.  Putting all mini
devices on 87.9 MHz would shift the interference burden to TV
Channel 6 (or the successor to that spectrum), lead to car-to-car
interference and create an attractive nuisance for pirates.
What mobile bandito would not relish the opportunity to capture
a bunch of receivers by running a few watts of power on a single
frequency?  The temptation will be too compelling.

  MORE ON THE MINI FM TRANSMITTER SAGA
  NAB president David Rehr has asked the FCC to recall
satellite receivers containing non-compliant mini FM transmitters.
In response, Sirius Satellite says NAB is simply "muddying water,"
but Sirius is in no position to complain after admitting that some
of their staff members authorized the manufacture of non-compliant
transmitters.
  Any product recall should of course involve not only satellite
receivers with non-compliant transmitters, but iPods, MP3 players
etc. with similar unacceptable devices.

  DOW JONES RESPONDS ON WIDEBAND NOISE IN THE AM BROADCAST BAND
  Bob Dreste, Phoenix, has a valid point regarding the type
of antenna used with a vehicle's AM radio [CGC #754].  However,
my drive from Ventura to the Denver/Boulder area was in a Penske
16 foot van with a fender-mounted antenna and the drive back to
Ventura was in a Malibu.  The perceived unwanted noise in the AM
broadcast band was the same in both cases.  Also, my Prius - with
a standard roof-mounted antenna - receives the same noise in
Ventura as did the truck and Malibu.

  INTERFERENCE FROM MINI FM TRANSMITTERS ("MODULATORS") ETC.
  There are numerous issues here in Chicago with FM
interference near "Athletic Centers" that use FM modulators
to send TV audio to people while they work out.  Within at least
1000 feet these modulators cause problems, similar to the ones
that the XM and Sirius modulators cause.
  Some of these businesses are located on major highways
and streets and cause numerous issues with real time listening.
If we could show that these situations are radiating signals
above the Part 15 limit, is the FCC interested in doing anything
about it?
  I too have noticed gas pumps and some RF motion detectors
causing issues with AM and FM reception.

  RE: CELL SITE WORKER SHOT AT NIGHT BY POLICE DIES ON THE JOB
  Having been employed as a police officer and also in a
position which necessitated working after hours, I offer the
following suggestion (which would have possibly saved this poor
man's life - [see lead story in CGC #753]):
  When working at non-business times, or in unusual locations
and especially if working in a bad area, contact local law
enforcement, notify them of the situation and request a "safety
check."

  REVISED IBOC FM SPECTRAL MASK
  The spectrum plot below shows the increase (in green) in
the proposed adjacent channel digital noise created by the FM
IBOC system.  The outer limit of the original mask was 215 kHz.
Now iBiquity wants to limit pushed to 250 kHz.

******************************************************************
  TURN FM IBOC OFF?
  Since iBiquity is changing the FM IBOC mask to match real-
world measurements, does that mean all present FM IBOC stations
are in violation of the current RF mask rules?  Maybe IBOC
should be shut-off like the out-of-spec XM/Sirius FM modulators.

  FAA PROPOSAL WOULD HAVE ENORMOUS IMPACT (LEAD STORY, CGC #743)
  Here is a little FAA gem that could affect many users of
the RF spectrum.  In the proposed modification to 14 CFR 77.9(e)
(1), the FAA would require that notice be given for the
construction of a new, or modification of an existing facility,
i.e. building, antenna structure, or any other man-made structure,
which supports a radiating element(s) for the purpose of radio
frequency transmission operating in the following frequency
groups:
  54-108; 150-216; 406-420; 932-935/941; 952-960; 1,390-1,400;
2,500-2,700; 3,700-4,200; 5,000-5,650; 5,925-6,525; 7,450-8,550;

  During the second quarter of this year, Verizon Communications

  "The officers absolutely love it," said Sgt. Dan Gomez of
LAPD's Tactical Technology Unit. "Whenever I take it to any of
our divisions, the number one question is, "When am I getting
one" or "Can I borrow yours?""
