  50,000 WATT KSPN(AM), LOS ANGELES, DISCONTINUES HD RADIO
  AND TURNS ON MDCL

  KSPN, 710 kHz, Los Angeles, has implemented MDCL and should achieve 
considerable electric energy savings with little or no detrimental 
effects to its listeners.  MDCL was described in CGC #1089.

  Of much greater interest is this comment imbedded in the underlying 
letter from the station's Chief Engineer, Mike Tosch:
"KSPN no longer runs AM IBOC and runs full 125% positive peak (and) 
full NRSC modulation."  These are monumental steps forward for KSPN, 
the listeners of KSPN, and the listeners of adjacent channel stations 
who will no longer receive HD splatter.

  According to one source, the number of listeners who will benefit 
from the absence of HD far outnumbers the HD listeners by virtually 
hundreds of thousands in a week for KSPN.

  Upon hearing the news that HD had been discontinued, the Chief 
Engineer of another AM powerhouse in the Los Angeles basin expressed 
his feelings in just seven words: "KSPN is to be thanked and 
congratulated!!"

  FCC NEWS BRIEFS - TV WHITE SPACES SLOWLY BEING UNLEASHED

  o  The FCC has approved the first TV white space database
  system operated by an outside company and the first device
  to transmit on an unlicensed basis on so-called unused
  frequencies in the TV bands.  This means, among other things,
  that the days of fringe area TV reception are numbered:

  http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-311652A1.doc

  o  "We [the FCC] disagree with the EIBASS that the [white
  spaces] databases should protect the service of Mexican and
  Canadian stations in the territory of the United States because
  Section 15.712(g) of the Commission's rules provides that TV
  bands databases are not required to protect the portions of
  Canadian or Mexican television stations' contours that fall
  within the United States...."  See page 2, paragraph 3:

  FCC NEWS BRIEFS - GENERAL

  o  Less than one year remains for land-mobile radio licensees
  in the 150-174 and 421-512 MHz bands to transition to narrowband
  operations:

DA-12-12A1.doc

  o  The FCC has adopted a new "threshold qualifications"
  procedure for awarding commercial FM allotments using "Tribal
  Priority," and has expanded opportunities for Native Nations to
  acquire commercial FM stations for broadcasting to tribal lands:

  o  Henning Schulzrinne has been appointed as Chief Technology
  Officer at the FCC:
  http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-311578A1.doc

  o  In round numbers, there are 10,000 full power FM stations
  (commercial + non-comm), 6,000 FM translators and boosters and

  equipment manuals and other historic documents from the dumpster
  and contributions to the site are welcome:

  o  Legislator's bill would make certain copper thefts
  a felony:

  o  FCC reports to Congress regarding the economic impact
  of LPFM stations on full-service commercial FM stations.
  They conclude that, "on the whole, LPFM stations do not
  currently have, and in the future are unlikely to have,
  a demonstrable economic impact on full service commercial
  FM radio stations."
