  MEXICO ADOPTS U.S. HDTV STANDARD
  Mexico has formally adopted the U.S. (ATSC) Digital Television
Standard for terrestrial broadcasting.  Since Canada adopted the
same standard in 1997, it can now be said that ATSC is the North
American DTV standard.  ATSC has also been adopted by South Korea
(November 1997) and Argentina (October 1998).

  THE SKELETONS IN IBOC'S CLOSET
  "Those IBOC sidebands from other stations are killing our
fringe listeners, why didn't you tell me this was coming?"  Those
could well be the words of a radio GM scolding the station's Chief
Engineer for not sounding the alarm bell about AM & FM IBOC
("HD Radio") and the damage IBOC's first adjacent channel
sidebands can do to the fringe-area signals of radio stations
- perhaps your station.  From what we have seen, the AM IBOC
system is particularly prone to causing interference.
  If there is one article in the past six months that should be
considered MANDATORY READING for every radio engineer - as well as
the SCT (Mexico's FCC) - it is this one:  "A Look at the Digital
Horizon" on page 8 of Radio Guide for July 2004.  As Project 
Leader, Radio Broadcast Systems, at the Communications Research
Center in Ottawa, Canada, the author was responsible for
research on new digital radio broadcast technologies.  Download
the entire magazine by clicking on the URL below (high speed
Internet connection recommended), then go to page 8 of the pdf.
  This is important reading.  Don't let your eyes glaze over.
You need to translate the salient points for the top brass at
your station.  (The audio time delay built into IBOC broadcast
equipment is a detriment not mentioned in the article, but one
that you will probably want to discuss as well.  That delay is
a killer for certain broadcast applications.)

  AN E-MAIL FAILURE
  CGC's Internet Service Provider has suffered a major
server failure.  While CGC can send e-mail, we cannot receive
any mail.  The problem began Sunday night and will hopefully be
resolved by the close of business on Tuesday.

  TELESCOPING FIBERGLASS MAST
  Here's a handy gadget.  The Mast Company has announced
the availability of a 32 foot fiberglass telescopic pole ($115)
suitable for supporting lightweight items.  The pole collapses
to 46 inches for transportation and storage.  According to the
company, these poles are "very strong" and were "originally
designed for windsocks."
  Stackable Aluminum tubing and other assorted goodies are
also available from The Mast Company.  (As usual, this is not
an advertisement, just a gratis announcement on a product CGC
found interesting.)

  URL FOR QUALCOMM STORY ON AIRBORNE CELL PHONES
  Last week we mentioned that Qualcomm executive Irwin
Jacobs was in the air aboard a chartered American Airlines
jetliner showing reporters how easily wireless phone calls
could be made without interfering with aircraft navigation
systems.  The Qualcomm story appeared at a registration-required
web site, and we refuse to subject our readers to that kind
of site.
  Fortunately, USA Today also carried the story, and you may
read the complete text registration-free at:
