  RESULTS OF SECOND ROUND OF DTV CHANNEL ELECTIONS
  KESQ-TV, Palm Springs, has tentatively chosen to use
CH-42, its current NTSC channel, for its permanent DTV
operations, and KAJB, Calipatria, has tentatively chosen to
use CH-36 as its permanent DTV channel.  (KAJB currently
uses CH-54 for NTSC and CH-5 for DTV.)

******************************************************************
  MEASUREMENT STANDARDS FOR DTV SIGNALS PROPOSED
  The FCC has proposed to amend it rules to include
measurement standards and procedures for determining the strength
of a digital television (DTV) broadcast signal at any specific
location.  The procedures would be used as a means of determining
whether households are eligible to receive distant DTV network
signals retransmitted by satellite carriers.  Included is a
proposal to use a directional receiving antenna for field
strength measurements.

  FCC FORFEITURE WATCH - SELECTED ITEMS
  Alleged Los Angeles pirate on 87.9 MHz notified by FCC of
apparent unlicensed operation.  "Your operation.... was measured
at 1,340,000 microvolts per meter (uV/m) at 3 meters.  This
exceeds the allowable unlicensed limit of 100 uV/m at 3 meters..."
(first URL below).  [This means the alleged pirate was 179 million
times too powerful.]
  Alleged San Diego pirate on 96.9 MHz notified by FCC of
apparent unlicensed operation.  Two letters - last two URLs
below.  (Because the 96.9 pirate changed locations, it seems that
the FCC has to start its notification process all over again!)

                           RANDOM NOTES
******************************************************************
  WHAT ABOUT OVERPOWERED MINI-FM TRANSMITTERS?
  A CGC Communicator reader in Fresno writes that he has been
following the FCC Part 15 issues raised in the Communicator as
they pertain to the mini-FM transmitters used with Sirius and XM
receivers, Apple iPods and other devices.  He asks if any of
CGC's research at a local Circuit City store included checking
the devices for FCC Part 15 field strength compliance.
  In reply, CGC's research did not include field strength
checks because that type of measurement should be made in a
controlled environment, not in a retail store where signal
reflections are likely to be problematic.  However, at least one
national organization is planning to take formal measurements and
will undoubtedly file their data with the Commission if, as
suspected, overpowered operation is found.
  CGC chose to "get the ball rolling" at the FCC by filing a
complaint that focused on one easy-to-verify claim: That Sirius
should not be marketing mini-transmitters capable of operating on
87.7 and 87.9 MHz.  Our limited research found no XM units with
these frequency problems, but our readers have indicated that
some XM units and many other mini-transmitters are indeed capable
of out-of-FM-band operation.
  Much work remains to be done by others on issues such as
field strength checks on iPod add-on transmitters and similar
devices, and their out-of-FM-band capabilities (e.g. use of 87.7
and 87.9 MHz) -  and the FCC needs to be advised of the results
with copies to WTB, OET and FCC Labs.
******************************************************************
  LETTER TO THE EDITOR SUPPORTING THE USE OF "BELOW 88" FREQS.
  "My feeling on any small transmitter for an XM, Sirius, HD or
MP3 players is that they SHOULD use these out of band frequencies.
Currently, FCC Rules do not allow this, but the situation deserves
careful examination and consideration.  Given the interference
these devices cause to mobile on-channel reception of legitimate
stations, we should give them out of band authorization (but not
above 107.9 MHz).  As a user, I cannot find a clean channel to
use in Los Angeles for my XM receiver.  As a licensee, I would
not want them on my channel."
  Los Angeles Broadcast Engineer
  Editorial Comment:  The problem is that Channel 6 stations
do not want these intruders in their spectrum either.  Channel 6
stations (such as KSFV-LP and XETV) operate over the span of 82 to
88 MHz with aural carriers typically centered on 87.75 MHz.  It
is a fair bet that KSFV will hang onto its CH-6 allotment after
the DTV transition occurs, and we already know that Mexico plans
to continue NTSC broadcasting on CH-6 for many years to come.  Now
if car radios had an "audio in" jack or Bluetooth capability....

  BARRY McLARNON OPINES ON A SHORTCOMING OF AM HD RADIO
  Design flaws in the AM HD radio system are the heart of the
problem according to Mr. McLarnon.  His letter is posted here:
  http://earthsignals.com/add_CGC/Letters/IBOC_Spin.htm
******************************************************************
  COMMENTS ON FM HD RADIO HEARD ON THE NAB FLOOR
  A number of broadcast engineers have expressed opinions
on the future of FM HD Radio.  One very positive comment from
the Seattle area was that HD-1 fixed nasty multipath problems
and therefore deserved a gold star.  At the other end of the
spectrum were a number of opinions that consumers are unlikely
to adopt FM HD technology in large numbers for reasons of cost,
the seven second acquisition delay when tuning directly to an HD-2
(or 3) channel, digital distortion accompanying low bit rate
channels and the fundamental fact that HD Radio signals have
limited coverage range compared to the host analog station.
  NPR now has HD coverage data on over 30 educational FM
stations.  In order to hear an HD channel 97% of the time, the
companion analog field strength (which was also measured in NPR's
tests) needs to be - in the median case - well beyond 70 dBu.
The take-home message is that broadcast stations are likely to
be disappointed with the limited range of their add-on HD
channels (e.g. HD-2 or HD-3) because there is no "analog
fallback" to cover the 3% of digital dead air.
******************************************************************
  CPB SEEKS APPLICATIONS FOR RADIO INTERFERENCE STUDY
  Radio frequency interference impacts both analog and HD
listeners, and the Corporation for Public Broadcasting (CPB)
wants to know the extent of this interference as it impacts
public broadcasting stations.

  KAVR RADIO TOWER MAKES FOR A TALKATIVE NEIGHBORHOOD
  If you give Kate O'Rourke a telephone call and listen
closely, you might be able to catch the weather report from
KAVR, Apple Valley, the radio station behind her home.  To
those of us in the broadcast industry, such RFI reports are
not uncommon - but the O'Rourke case is a colorful report
appearing in the mainstream media:

******************************************************************
  "NATIONAL SOS" SYSTEM WOULD PUT FRS/GMRS RADIOS TO USE
  A proposal being advanced by a radio manufacturer, a citizens
band radio group and the DC Emergency Radio Network encourages
emergency use of inexpensive Family Radio Service (FRS) and
General Mobile Radio Service (GMRS) walkie-talkies when disasters
such as Hurricane Katrina cause major outages of the
communications infrastructure.  "National SOS" recommends
broadcasting calls for help on FRS Channel One, which could then
be relayed by amateur radio operators to the appropriate emergency
responders.  (Mobile Radio Technology, National SOS)

Cingular tower fire story (they're a major client of mine) and

  HEAR A SCINTILLATING STAR
  Kerry Banke of Qualcomm - well known for his Laser Communicator
work in amateur radio circles - has rigged up a device that allows
him to hear the scintillations of a star.  When someone asked him
for a recording of the sounds, he put the audio into a wav file
and shared the results with us.
  Kerry said he used a four inch lens and about $5 worth of
electronic components to capture the sounds.  He adds that,
"Most any star visible to the naked eye will be audible with
this setup."  Kerry is N6IZW and his wav file (about 1.3MB) is
available here:
