  TEMPORARY STAY GRANTED IN BROADCAST AUXILIARY MATTER
  "In this Order, we grant a Request for Temporary Stay
(Request) filed by the Society of Broadcast Engineers (SBE)
to delay the effective date of prior coordination procedures
adopted by the Report and Order in the above-captioned
proceeding for most fixed point-to-point Aural and TV Broadcast
Auxiliary Service (BAS) stations.  SBE requests the stay to
allow BAS licensees time to provide and to correct BAS receive
site information in our licensing database, the Universal
Licensing System (ULS), to ensure that the new procedures
effectively avert interference to existing systems.  We grant
the requested relief for six months, delaying the effective
date to October 16, 2003...."   - FCC

  FAA TO SEND CLEARANCE DATA TO FCC ELECTRONICALLY
  According to a Primedia trade publication, the FCC and FAA
have announced that tower and antenna airspace clearance data
from the FAA will now be transferred electronically to the FCC.
This development will enable the Commission to process antenna
structure registration applications faster and more accurately,
and will save staff time at both ends.  The electronic transfer
of data is expected to reduce the time it takes to get this
information into the FCC's database from one to two weeks
to one day.

expected to launch this summer.  California is joining in the
national Do Not Call registry which is FREE to consumers.  If
you sign up today, you can stop unwanted telemarketing calls

  From an archived December 1974 CGC newsletter comes this

led to the collapse of two tower structures in San Diego County
in 1974.  Rust lives!  Check your guy anchors regularly.

                     LETTERS TO THE EDITOR
******************************************************************
  VERY IMPORTANT PART 74 NEWS
  The following URL gives my summary of the various frequency
coordination related meetings at the NAB Convention.  Basically,
the FCC has written a sweeping set of changes to the Broadcast
Auxiliary Service ("BAS") Part 74 rules.  In many cases, the FCC
has re-written the BAS rules to align our rules with the Part 101
(microwave) and Part 90 (land-mobile) rules.
  Please take the time to study the matter and make your
feelings known to the FCC.  It is important that your station
file comments.  Some of these proceedings will severely affect
your station's BAS operations.  And this is NOT just a TV
matter as it includes 950 MHz Aural STLs, so it includes RADIO
too!
  http://www.earthsignals.com/add_CGC/Howard_Fine_NAB2003.htm
  Also, look at all of your Part 74 licenses now.  If they are
not printed on a funny green colored Form 601, they are probably
not valid.  If you have a fixed-link license, make sure it has
BOTH Location 1 and Location 2 data shown.  Otherwise, you are
out of luck.  Failure to check your licenses NOW is an invitation
for problems, and you don't need that!
  Howard Fine, SCFCC
  P.S.  I can't wait for the first station to get interference
from a PCN type coordination.  Wait until they find out that all
of the "protection" issues we have had on channels will go away.

  READERS RESPOND TO "WHAT STATION WAS THAT?" (CGC #568)
  The radio studios that were featured in the film "American
Graffiti" where Wolfman Jack was shown on the air, were at the
site of the former KRE on Ashby Avenue in Berkeley.  This location
is still the transmitter site for KRE and KFRC(AM); the two
stations diplex into a common tower.  The big red light bulb on
the side of the rack in the air studio was the alert indicator
for the EBS receiver.  I worked at KFRC at the time.

  I was Chief Engineer for KRE, Berkeley, CA (now KBLX) at the
time the film was made.  On the day of the filming, we shut the
station down at midnight and the location crew worked with the
Wolfman until 6 AM.  For more info on the old KRE building, and a
PR photo of Wolfman from the film, take a look at the web site

  NAB REFLECTIONS
  In Las Vegas, unlimited expansion seems to be a way of life,
so it pays NAB Convention attendees to have a Las Vegas street
map, a NAB floor map, and a specific plan for seeing the exhibits.
  Walking the aisles, one can't miss the slick, if not hypnotic,
presentations made possible by computer technology.  Powerful
wares for audio and video editing allow one person to do more
production, do it faster, and still be creative in the process.
In many ways, the NAB is being converted into a high-end
multimedia convention driven by remarkable advents in technology.
  TV, AM and FM digital broadcasting is generating a
tremendous amount of activity for audio, transmitter, and antenna
manufacturers.  However, questions remain about the real world
large-scale deployment of iBiquity's AM and FM DAB systems.  Who
will be the winners and losers from an interference standpoint,
and when will iBiquity's AM system be granted nighttime
authority?  We should know much more by NAB 2004 and be able to
share our practical experience with this exciting new technology.

  RADIO WORLD ANNOUNCES 2003 "COOL STUFF" AWARD WINNERS
  LAS VEGAS - The editorial staff of Radio World Newspaper
has announced the winners of one of radio's most prestigious
technology honors, the "Cool Stuff" Award.  The "Cool Stuff"
Award means a product was selected by a panel of radio engineers
and industry experts as notable for its design, features, cost
efficiency and performance in serving radio users.  It means the
product caused them to stop in the aisles and say, "Oh, cool!"

  LEONARD KAHN PROPOSES "CAM-D" TECHNOLOGY, REQUESTS STAY OF
  THE PRESENT FCC ORDER ON DIGITAL AUDIO BROADCASTING ("DAB")
  Kahn Communications has announced that it has developed a
new AM modulation scheme to compete with iBiquity's AM DAB
system.  Known as Compatible AM Digital, or CAM-D, Kahn claims
that his system is compatible with existing receivers, existing
broadcast transmitters and antenna systems, and will not increase
adjacent or co-channel interference.  Twice in the press release
Kahn mentions that his system has "15 kHz stereo fidelity"
without ever saying whether his system will send stereo.
  According to a number of engineers at the NAB Convention,
the Kahn announcement is untimely - the iBiquity DAB train has
already left the station.  On the other hand, the iBiquity AM
system cannot be used at night (yet) due to unresolved
interference concerns, so Kahn's system is not positively out
of the running.
  The Kahn Communications announcement doesn't provide much
technical detail on CAM-D, but yields lots of fuel for discussion.

  NEW "SCA-LIKE" SERVICE WILL APPEAR ON PAGING FREQUENCIES
  According to REC Networks, a company called FreePage has been
successful in getting a developmental license to provide "Limited
Program Distribution Service" ("LPDS") in the New York City area,
using VHF paging frequencies.
  The intended service is like that of FM SCA service today.

  GROUP PROPOSES NEW BROADCAST SERVICE
  Consolidation of radio stations, freedom of speech, and public
access to broadcast stations are issues brought to bear in this
petition before the FCC.  According to REC Networks, a petition
has been filed by the "Citizen's Broadcast Band Discussion Group"
proposing a Notice of Inquiry into the establishment of a new
broadcast band reserved for non-commercial and exclusive use by
private individuals and small community groups.  See the text:

  COMCAST INITIATES BROADBAND RATE INCREASE FOR AT&T CUSTOMERS
  Many AT&T Broadband Internet users got a surprise in the mail
this month.  Comcast, the entity taking over AT&T Broadband, has
instituted a price increase of almost 33% for those who aren't
their cable TV subscribers.
  If you happen to be an AT&T Broadband user who was surprised
by this month's bill, you may wish to consider DSL at around $40
per month, available from many Internet Service Providers or your
local telco.  Be sure to check for special pricing packages that
can further reduce your monthly rate.

  HUBBLE SPACE TELESCOPE CAPTURES MORE INCREDIBLE IMAGES
  NASA's Hubble Space Telescope has captured a "light echo"
around a dull star in an obscure constellation in our galaxy.
The star, known as V838 Monocerotis, suddenly became 600,000
times more luminous than our Sun in January 2002, then rapidly
faded back into obscurity.  However, its "light echo shell"
continues to expand and evolve, much to the delight of astronomers
and members of the general public.  Check this one out:
