  LOW POWER DEVICES ON VACANT TV CHANNELS COMING SOON
  The Commission has adopted a First Report and Order and
Further Notice of Proposed Rulemaking taking the first major
steps toward allowing new low power devices to operate in the
broadcast television spectrum on vacant channels.
  The Commission declined to permit operation on TV channel 37
that is used by radio astronomy and wireless medical telemetry
services; and on TV channels 52-69 which have been reallocated for
public safety and other mobile services.  It also declined to
permit the operation of personal/portable devices on TV channels
14-20 which are used by the public safety service in 13 cities,
leaving for further consideration the issue of whether fixed
devices might be used in that band.
  Marketing of such devices may commence on February 18, 2009,
after the digital television (DTV) transition is complete and all
TV stations are in operation on their permanent DTV channels.
It has not yet been determined whether the new low power devices
will be permitted on a licensed or license-free basis.

  FCC REQUESTS NOMINATIONS FOR NEW EMERGENCY ALERT COMMITTEE
  In this Public Notice, the FCC seeks nominations for
membership on its Commercial Mobile Service Alert Advisory
Committee.  The purpose of this committee is to "develop
recommendations on technical standards and protocols to
facilitate the ability of commercial mobile service providers
to transmit emergency alerts to their subscribers to the
extent such providers elect to do so."

  FCC ACTS ON QUALCOMM PETITION RE 700 MHZ INTERFERENCE PROTECTION
  The Commission has granted in part and denied in part a
Petition for Declaratory Ruling filed by Qualcomm Incorporated
regarding the requirements for interference protection in the
700 MHz band.  This item should be of particular interest to
TV broadcasters currently occupying Channels 54, 55 and 56.

  FCC RELEASES LONG-AWAITED "OMNIBUS" AMATEUR RADIO R&O
  The FCC has issued a Report and Order (R&O) in response to
nineteen petitions for rulemaking and one informal request for
Commission action on various items of interest to the Amateur
Radio community.  Major actions involve the expansion of HF voice
privileges for many HF operators, and the permitting of Auxiliary
operations (e.g. linking) in most parts of the 2-meter band (see
paragraphs 20-23 in the R&O).
  The first URL takes you to ARRL's overview of the R&O.
The second URL gives the full R&O text, all 44 pages.

  FCC FORFEITURE WATCH - ITEM #1
  An official FCC Citation has been issued to Kachun Wong
(LightObject d/b/a Actionbuy Trading Co.) in Sacramento, CA for
marketing in the U.S. a "10 Watt 1.2 GHz Wireless Camera Video
AV Transmitter Receivers."  The equipment is not even eligible
to receive a grant of equipment certification because the band
in question is allocated to aeronautical navigation where no
interference is allowed.

******************************************************************
  FCC FORFEITURE WATCH - ITEM #2
  Shawn Deroux has been ordered to pay a $10,000 fine for
operating a pirate station on 87.9 MHz in Bronx, NY.  Since Deroux
did not respond to the Commission's earlier Notice of Apparent
Liability for Forfeiture in the amount of $10,000, that figure
was affirmed in the latest action.

  POWERFUL MOBILE FM PIRATES FROM A LARGE NATIONAL COMPANY
  The other day while driving on the 14 freeway, listening to
Kjazz at 88.1, my radio was captured by, "If your business needs
help with advertising, call...."  About that time a truck with
large signs covering every available inch with messages about
rolling billboards and tune to 87.9 for more information passed
me and the signal at 87.9 remained very strong as the truck
continued down the freeway out of view well over a few MILES
away.
  I was really curious, so I pulled off the freeway and called
the phone number and the man who answered informed me that this
truck was part of a LARGE NATIONAL company operating in many
states and this truck was part of a huge identical FM transmitter
equipped fleet!  The man I spoke with had NO IDEA what Part 15
was.  Judging by the range of this brute, I would venture a guess
that the power was MUCH greater than Part 15 allows.
  More problems for the "Reserved" Band!

  IF WE COULD DO LPFM OVER AGAIN
  What the FCC should have done with LPFM is exactly what they
did with LPTV.  LPTV and TV translators are licensed exactly the
same way, regardless of whether the input is baseband or RF.
Instead of launching a whole new service, they should have allowed
FM translators to be programmed directly as long as they were not
operated as commercial broadcasters.  The interference
restrictions on FM translators are much tighter than the LPFM
rules, and include protections to high-power FM service beyond the
predicted 60 dBu FCC contour.  These also apply to grandfathered
stations with facilities in excess of current class limits.

  LIGHTING UP THE NIGHT SKY, AND CAPTURING THE SIGNAL
  Just for fun, I fired up the 150W high pressure sodium (HPS)
lamp in my backyard the other night (see CGC #760) to light up
the coastal low clouds, and was able to copy the signal three
miles away.  I have attached a JPEG of an audio spectrum screen
capture using Spectrum Lab software.
  The 120 Hz line is all of the other lights in the county,
and the 135 Hz line is the 150W HPS lamp received three miles
away.  The lamp is being driven at 67.5 Hz, so it flickers at
twice that rate, or 135 Hz.
  Although the lamp was being driven with straight 67.5 Hz
power for this test, the received signal is strong enough that
we could easily copy text using Jason serial tone modulation.
We'll probably set up to do a two-way text QSO using Jason and
the HPS lamps via clouds soon.

  ONE WIRE POWER, TERMITES, AND A MODEST CORRECTION
  Parts of Australia use a one-wire electric power distribution
system and rely on earth conductivity to provide the "second wire"
to complete the circuit.  According to Tony Abbott, "I saw this
system in rural Australia last year.  Each farm had a transformer
mounted on a pad or on the power pole (about 5' above ground and
fenced off)."  See the URL below for details.
  Ken Dickson, W6MF, who recently returned from a trip to
Australia and reviewed the URL, added these thoughts:
  "I'm sure that this must be the system because we saw
miles and miles of it.  We were told about a bad termite problem
throughout Australia, and because of the problem all of the power
poles we saw were made of concrete.  I don't know what gauge wire
they used on the single wire because they were all quite elevated
(higher than our domestic power lines).  The majority of what we
saw was a substantial size wire; I'd estimate no less than 1/4
inch.  I'm sure that it was certainly more cost effective than
our two and three wire transmission systems."

  COMMENT ON XM'S LACK OF FCC RULE COMPLIANCE
  XM Satellite's FCC filing to correct the technical operating
parameters at some of its terrestrial repeaters (CGC #764) does
not sit well with a number of folks.  Paul Sinderbrand, a lawyer
with the Wireless Communications Association International who
represents companies with licenses to operate in the frequencies
adjacent to those used by XM and Sirius, is quoted as saying,
  "XM certainly seems to have a corporate inability to comply
with the FCC's rules.  This is all rather astonishing, especially
given XM's past compliance issues."  More from the Washington
