  NAB RADIO BOARD WANTS FCC TO PERMIT AM NIGHTTIME IBOC OPERATION
  The NAB Radio Board believes the FCC should authorize AM
nighttime IBOC (In-Band Off-Channel subcarriers for "HD Radio"
digital broadcasting) on an interim basis according to this
posting from Radio World:

  DIGITAL COPY PROTECTION
  Unlimited consumer video copying is destined to become a
thing of the past as we move into the digital broadcasting era.
The FCC will accept certifications from January 30 through
March 1, 2004 for the approval of Digital Content Protection
Technologies and Recording Methods to be used in Covered
Demodulator Products.

  XEKTT (XEPE) UPDATE
  Regarding XEKTT (XEPE), 560 kHz, Tecate/Tijuana, a group
of U.S. broadcasters has asked the FCC to rescind the Section
325(c) cross-border programming authority that the Commission
has issued to Pacific Spanish Network, Inc. (see CGC #611).
Turns out that Pacific would ordinarily be allowed 10 days to
respond to the interference charges that have been filed against
them, but Pacific now asks for two and a half months to do so.
  No way, say the U.S. broadcasters.  They object to any
extension of time arguing that (a) severe interference from XEKTT
to nearly 29 million people within the protected contours of the
affected U.S. stations deserves immediate (not delayed) action,
(b) only a few days should be needed to review and comment on the
engineering interference showings already submitted, and (c)
XEKTT's internationally uncoordinated operation is on its face a
violation of the U.S./Mexican AM agreement which is sufficient
grounds for immediate dismissal of the cross-border permit.
  Stay tuned for the next chapter in this saga.

  ARE WE HEARING MEXICAN INTERFERENCE ON 740? (CGC #605-611)
  Bill Agresta, Chief of KBRT, 740 kHz, Avalon, along with other
station staffers and listeners, have reported intermittent Mexican
interference on 740 kHz.  In one such recent instance, Bill was at
the Catalina "Airport in the Sky" and heard what was evidently a
Mexican station fire up for a few minutes on 740 kHz.
  The Catalina airport is just 3.5 miles from the KBRT
transmitter site, but in a pattern null.  The interference was
not strong enough to override KBRT at that location, but it was
audible, suggesting that some serious power was in use.  Now
we wonder, if Mexican broadcasters are testing on 740 kHz, what
else is being planned?

  LA's 1580 BLOWTORCH CHANGES HANDS AGAIN
  All of the Radio Unica stations, including KBLA 1580 Los
Angeles, have been sold to Multicultural Broadcasting.  However,
you may still hear the name Radio Unica because Multicultural
also purchased the Radio Unica name.  It appears that
Multicultural Broadcasting will keep only the Los Angeles, San
Francisco and Houston Radio Unica stations.  The others will be
sold.  The transfer to the new owner is planned for Friday,
January 30.

  CELL JAMMING EQUIPMENT AND YOUR FAVORITE RESTAURANT
  I just read a recent article that suggests a trend toward
jamming cell phones in restaurants and other public places.  In
the January issue of the trade magazine Restaurant Hospitality,
a jamming device is described as being able to, "Make any mobile
phone within a 100 ft. radius inoperable."  One distributor
reports that at least 300 jammers of varying sizes have already
been exported into the U.S., some of them sold to restaurant
operators.  Here's a URL to the jamming equipment provider's
web site:

  ELECTRONICS REPAIR TECHNICIANS ARE VANISHING

  PRESSURIZE TRANSMISSION LINES WITH DRY AIR OR NITROGEN?
  Jampro notes that many broadcast transmission lines use Teflon
insulators and, with input from Dupont, has concluded that dry air
is better than dry nitrogen for pressurizing those lines.  The
reasoning is as follows.  Dry air is roughly 80% nitrogen and 20%
oxygen while dry nitrogen is obviously 100% nitrogen.  Should a
transmission line arc over (e.g. lightning hit), some carbon will
inevitably form as the Teflon is heated and disintegrates.
However, basic chemistry indicates that a lot less carbon will
form when dry air is used.  Since carbon is bad stuff
(conductive), the clear choice for a pressuring agent, in
Jampro's view, is dry air.
