  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.



  o  The Commission has issued an Enforcement Advisory discussing
  the illegal nature of cell jammers, GPS jammers and other radio
  frequency jamming devices:

  o  There is no shortage of jamming equipment available on
  the Internet as these examples show:

  o  Recent experimental grants (nationwide):



  o  KHJL(FM), Thousand Oaks, to KLSI

  o  KJLL-FM, Fountain Valley, to KLST-FM



  A $25,000 fine has been issued to Gabriel Garcia for pirate operations 
in San Jose, CA.

                           RANDOM NOTES


  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.



  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:

  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 

  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.



  o  Tower owners and others protest the new tower-vs.-bird
  regulations particularly because towers of all heights are
  now caught in the fray:

  o  While Europeans are looking at more efficient ways to use
  electromagnetic waves, the hue and cry from the U.S. FCC remains,
  "give the Internet folks more, more, more spectrum!"



  o  A curious (and possibly very useful) invention is scheduled
  to be displayed at the NAB Show.  The concept is to use DRM as
  an STL:

  o  There are expanded STL opportunities by using non-traditional
  frequency bands -- tutorial:



  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.



  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
