  THE GARZIGLIA LETTER ON FM TRANSLATOR LOCATION HOPPING

  CGC #1120 (February 13, 2012) reported on an unusual FCC
case -- the Radio Power case -- where the Commission came after
an FM translator operator in Wisconsin with "all guns blazing."
There is quite a bit more to the story.  See the Random Notes
section of this newsletter.

  MORE ON OMNIA'S IMPROVED FM STEREO TRANSMISSION SYSTEM

  Our last newsletter mentioned a most impressive field
test of Omnia's new FM stereo transmission system, a system
that is said to be fully compatible with existing receivers.
Greater Media performed the testing, acting as an outside
third party.

  The drastic improvement in signal-to-noise ratio ("s/n")
achieved when Omnia's system was switched on caused us to
wonder if perhaps a special receiver was used for that part
of the tests.

  According to Milford ("Smitty") Smith, VP Radio Engineering
for Greater Media, Inc., the same receiver was used for both
tests performed (conventional FM stereo transmission and Omnia's
new stereo transmission system).  The radio was a "garden variety
off the shelf FM auto receiver.  There was no special optimization
for [Omnia's SSBSC] mode."  The same garden variety antenna was
used in both tests too.

  Smitty added, "It is my understanding that if a receiver
were to be optimized for [Omnia's] mode, that the stereo s/n
would be appreciably improved over the current FMDSB case."

  The video of the field test speaks for itself.  The
improvements achieved when Omnia's system is switched on are
dramatic.  See and hear the test for yourself at the URL below.
Needless to say, Omnia will one of our must-see stops at the
NAB Show.

  THE GARZIGLIA LETTER

  CGC #1120 (February 13, 2012) reported on a very unusual
case -- the Radio Power case -- where the FCC came after an
FM translator operator in Wisconsin with "all guns blazing."
According to Radio World, Peter Doyle, Chief, Audio Division,
Media Bureau, was "'Hopping' Mad" about a translator that had
moved location or "hopped" again and again to a point far
from its original location.  Here is a refresher:

  http://tinyurl.com/TranslatorHopScotch
  http://tinyurl.com/FCC-Daily-Business-DA-12-185A1

  Ironically, there is nothing in the FM translator rules to
prohibit hopping and at one time Commission staff even helped
applicants in this effort.  So, how did we get from the point
where translators could hop, to the point today where they are
being heavily discouraged from doing so?

  The answer appears to lie in a letter dated September 2, 2011
from Peter Doyle to attorney John Garziglia.  Mr. Garziglia's
client was granted a hopping application so that an AM station
could make use of the translator, but Mr. Doyle took the
opportunity to issue a warning to others in what lawyers call
an Obiter Dictum, a "by the way" remark that is unnecessary for
the case at hand.  Here is what Mr. Doyle had to say:

  "Some translator licensees have attempted to accomplish what
would otherwise be dismissed as an impermissible major change
under Section 74.1233(a) by filing serial minor modification
applications to "hop" to new locations that are sometimes over
100 miles away.  We believe the filing of serial modification
applications represents an ABUSE of PROCESS.  We recently entered
into a consent decree with a party that acknowledged this practice
was an ABUSE of PROCESS and agreed to forfeit several authori-
zations.  The purpose of the overlap requirement is "[t]o prevent
... FM translator stations from abandoning their present service
areas."  The evident purpose of the serial applications is to
achieve the prohibited result.  No rule specifically prohibits
such a practice, but the Commission can take appropriate
enforcement action...."  [Words appearing in bold in the
original are capitalized above; footnotes omitted.]

  In summary, a series of minor hops could be viewed as a plan
to bypass the Commission's major change rules.  Such a practice
could also be seen as an end-run around the Commission's window
system for application filings.

  Now you have two very important pieces of information: The
FCC-to-Radio Power letter and a key excerpt from the FCC-to-
Garziglia letter that heavily discourages hopping.  We are told
that about 15 more letters like the Radio Power letter are about
to be issued to other translator operators.  If so, the
fireworks have only begun.

  THE KCEO(AM) SALE IS CONSUMMATED

  Last week's CGC Communicator discussed the pending sale of
KCEO, 1000 kHz, Vista, to Immaculate Heart Radio and noted that
FCC's AM Query page did not show the sale as consummated.  However,
the sale was consummated on March 2 according to paperwork filed
with the Commission on Saturday, March 3, see the URL below.
The organization that acquired the station is "IHR Educational
Broadcasting."

  KCEO is currently using three in-line towers for day and
night operation.  The new owner has inherited CPs for four-tower
operation (both day and night).  A new fourth tower will be
required.  It is not the unused fourth tower that is currently
on the property.

  To the new owner of KCEO -- Welcome!  We wish IH Radio the
best of success with its new acquisition and in activating its
4-tower CP.

  TWISTED RADIO WAVES -- POSSIBLE TWISTED LOGIC

  This story (first URL) claims that, "'Twisted' Waves Could
Boost (the) Capacity of Wi-Fi and TV."  But we can already double
the capacity of plain-Jane communication circuits by using
separate Hpol and Vpol antennas, or oppositely-sensed circularly
polarized antennas.  So, no new technology is needed to reproduce
the 2X increase in link performance that these guys claim to have
demonstrated with great fanfare and splendid publicity.

  Now if this group demonstrates five, 10 or 20 programs being
transmitted simultaneously in the same spectrum by using only
'twisted waves,' a lot of people will take note.  The demon-
stration performed is simply unconvincing.

One thought on “CGC #1125

  1. In RE: # 1125
    MORE ON OMNIA’S IMPROVED FM STEREO TRANSMISSION SYSTEM
    Something seems odd to me when listening to / viewing the two samples of audio in the demonstration. The November 15 (FMDSB) audio does not sound like ‘multipath’ as I’ve experienced it; rather it sounds like ‘no RF’, i.e. the radio has nothing to demodulate. I would describe mulitpath as a brief audio anomaly manifested as noise that might be ‘described’ as “pffft, pfft, pfft”. The Nov. 15 audio is simply “missing.”
    The November 16 audio (SSBSC) has good examples of what I have experienced as multipath.
    So, I’m completely unconvinced – though the Omnia scheme may indeed produce a reduction in multipath, this demonstation does not relate to any multipath situation I have experienced.
