  FCC Enforcement Watch

  A recent FCC Notice of Violation for Pacifica Foundation
states in part as follows:

  "47 C.F.R. S 74.1265(b): "The call sign of the translator
or booster together with the name, address, and telephone number
of the licensee or local representative of the licensee if the
licensee does not reside in the community served by the translator
or booster, and the name and address of a person and place where
station records are maintained, shall be displayed at the
translator or booster site on the structure supporting the trans-
mitting antenna, so as to be visible to a person standing on the
ground at the transmitter site.  The display shall be prepared to
withstand normal weathering for a reasonable period of time and
shall be maintained in legible condition by the licensee."  At the
time of inspection, no information was observed concerning [FM
translator] station K212FV at the base of the supporting

  Are your boosters and translators 74.1265(b) compliant?

  The good folks in Washington should wipe this burdensome rule
off the books.


  Spamcop + Communicator Cutoff Date + Important Question

  Software known as Spamcop is suddenly rejecting a number
of CGC Communicator newsletters, apparently because of our use
of story titles with all capital letters (some think of this as
"shouting").  No problem.  This week's newsletter has been
recast to eliminate strings of all-capital letters.

  In other news, it's official:  On Wednesday, May 29, 2013
(or shortly thereafter) XO/Concentric/Connectnet plans to
terminate the circuits we use to upload The CGC Communicator
newsletter.  (This is a nationwide change and not one specifi-
cally directed at the Communicator.)  We hope to begin closed-
loop tests on a new distribution method soon and plan to be
clear of XO/Concentric/Connectnet by Tuesday, May 28, 2013.

  Important question:  If your station or company is one of
CGC's clients, on a scale of 0 to 5 how valuable are our once-a-
month Local FCC Applications & Actions listings?  "Zero" means
no value, "five" means great value.  Just "reply" to this news-
letter to let us know, and include your station call sign or
company name.

  General Notes of Interest


  o  Gold Coast Broadcasting has a series of translator
  applications pending for various frequencies (96.3, 96.5, 98.9,
  99.3, 99.5 and 104.9 MHz) for Solimar Beach.  However, all of
  these stations are to be located in the Pacific Ocean well off-
  shore (34-10-46N, 119-28-04W).  We are told that there just
  happens to be an oil rig at those coordinates.


  o  On the shutting down of Dielectric's antenna and
  (we are told) RF filter businesses:

  o  Harris Broadcast repositions to reduce staff.  "Total
  reduction is less than 10%, spread over a full-year time frame,
  on a global basis," said Harris Broadcast CEO Harris Morris:

  o  Expect ISDN changes from Verizon in May:

  o  The trend toward low-profile receiving antennas in cars,
  combined with increased computer hash from the car's electronics,
  is creating the perfect storm for diminished radio reception,
  especially AM:

  o  Frightened by changes in the car dashboard?  Lots of
  radio people are.  No one has figured it out but here is
  what seems to be happening:

  o  Radio is still the absolute king for listening audience,
  report finds:

  o  Silicon Labs releases digital radio chips for FM, HD,
  DAB and DAB+.  They feature antenna-in-to-audio-out on a
  single chip:

  o  Aereo is set to expand its service to Boston on May 15,
  bringing local over-the-air TV signals to computer screens:

  o  IT management challenges engineers:

  o  Patent trolls are being branded as "legal leeches,"
  and for good reason:

  o  Richard Rudman maintains that the U.S. still does not
  have a unified and coherent public warning strategy 12 years
  after 9/11/01:


  Improving Time Signal Reception on Atomic Clocks

  Here is an article about improving time signal reception
on "atomic clocks."  Overlooked is the fact that WWVB added
phase modulation ("PM") in Oct. 2012.  New clocks with PM decoding
capability will work much, much better than the current generation
of clocks.  That one monumental improvement (adding PM) will
solve a whole bunch of reception problems instantly.

  Tech Letters

  The most recent Tech Letters postings include the following:

  o  Roy Trumbull shares his memories of the Solar One power
  plant on the road from Needles to Barstow.  Does the plant
  still exist?  Is it operational?

  o  Roy Trumbull reminds us of the perils of using two or
  more microphones where "acoustic phase cancellation" results
  in "comb-filtering" when audio outputs are combined.  Roy
