  DTV FIELD TESTING IN LOS ANGELES & VENTURA

  Neil Mazur of KCAL-TV, Los Angeles, recently "took to the
streets" in one of his station's masted vehicles to see firsthand
how conventional 8-VSB DTV transmissions were performing.  While
his survey was "neither scientific nor comprehensive," he came
back a bit disappointed.  Neil writes,

  "I'm curious to know if any of the other stations have done
any of their own coverage tests in this market and would like to
share their findings.  Also, if anyone would like to join us
when we embark on our next field trip, please let me know."

  Neil's entire letter is posted at:

  COFDM BLOWS THE SOCKS OFF 8-VSB IN DTV FIELD TESTS

  Sinclair is currently broadcasting DTV signals at 50 kW
on Channel 40 in Baltimore.  Using the same transmitter,
transmission line and antenna, they switch between 8-VSB and
COFDM modulators and have invited the broadcast industry to
witness the results.  COFDM is not only superior, it is "far
superior" in heavy multipath environments according to Pappas'
VP for planning and development who witnessed the tests.

  Read the article for yourself in Broadcasting & Cable
magazine for July 5, page 10.  The DTV broadcast industry should
seriously consider switching to COFDM before it is too late, and
it is our responsibility as engineers to keep management informed
on this crucial issue.

******************************************************************

  MAJOR FINES

  $7,000 + $8,000:  Failing to have a meaningful managerial and
staff presence at the KNTB(AM) main studio + transferring control
of the station's license without prior Commission authorization.
http://www.fcc.gov/Daily_Releases/Daily_Business/1999/db990709/da991255.txt 

  $14,500:  A new FM station in Puerto Rico began operation
on the wrong frequency and built their main studio too far away:
http://www.fcc.gov/Daily_Releases/Daily_Business/1999/db990707/da991328.txt 

  $100,000 (reduced from $200,000):  For operating 21 unlicensed
microwave paths and two unlicensed frequencies on a licensed
microwave path for periods ranging from one month to 21 months:

  THE LAST WORD ON REPORTING TOWER LIGHT FAILURES

  A number of letters continue to reach us expressing various
opinions about how the position of a tower should be described
to the FAA when a tower light failure occurs.  Fortunately, FCC
Rule Section 17.48(a) [current as of October 1, 1998] tells us
exactly what information SHALL be given to the FAA, so let's start
there.  In terms of position information, you are only required
to furnish the FCC Antenna Structure Registration Number.  You do
NOT have to give the tower coordinates or the street address or
the location of the structure relative to aircraft navigation
aids.

  While you might offer the coordinates and tower address that
appear on an FCC authorization, be careful about offering vectors
from aircraft navigation aids unless you are absolutely certain
of the facts.  Did you measure the vectors in nautical miles
and degrees magnetic, and so advise the FAA?  Could you have made
a mistake in your measurements or in plotting the location of
your tower?  Was the nav aid moved between the time you looked
it up and the time the tower lights failed?

  The bottom line is that it would be tragic if an aviation
disaster occurred because of outdated or incorrect information.
We all want to be helpful, but we need to be extremely careful
on matters involving safety of life.

  GETTING RID OF IMPULSE NOISE ON NTSC TELEVISION PICTURES

  Sparking-type power line and ignition noise interferes
with the pictures of many TV stations - especially low-band
VHF stations.  For $3,200, there is a magic box that goes on
the receiving end and eliminates this type of problem.

  We first learned about the Intelvideo Digital Impulse
Noise Reducer (model INR-ES and the companion IFDM Intermediate
Frequency Demodulator/Modulator) about a year ago, and the field
reports have been outstanding.  Intelvideo also manufactures a
digital co-channel filter and a Noise Reducer/Ghost Buster, but
we haven't used these devices yet.

  Intel's video products are sold by a company called Mega
Hertz.  The contact is Mark Long @ (800) 883-8839.

  WHAT PAGER SERVICES WORK WELL IN SOUTHERN CALIFORNIA?

  What company provides your paging service, do you receive
pages reliably and where do you receive the pages (give us
general area descriptions like L.A., San Diego and San Bernardino).
Have you had bad luck with any particular paging company?  Send
us an e-mail.  The results of this informal survey will be
published in an upcoming Communicator.

******************************************************************

  EQUIPMENT RACKS AVAILABLE

  Cox Communications San Diego has a few dozen 19 inch equipment
racks made by Optima that we are willing to let go for the low low
low price of $50 each!  The one stipulation is that whoever wants
them must come and remove them from the sites (one in Downtown San
Diego and the other in Chula Vista) and transport them at their
expense.  These are approximately six foot tall racks and are what
we like to call "Scientific-Atlanta green" in color.

  These racks accommodate equipment mounting on either front or
rear, have tops and rear doors but no sides.  All are in very good
to excellent condition.  They were originally purchased for
approximately $600 each.  Interested parties should call me at
619-266-5567 or email dennis.younker@cox.com

  HELLO FROM TEXAS

  Greetings from the H.O.T. (Heart Of Texas).  I've been
chief for eight of Capstar's central Texas stations now since
the first of the year.  Based in Waco, which is a lot like my
home town of Topeka, KS.  I love it.  No smog, no congestion,
no long lines at the B of A.

  KRCK PROPOSES A TRANSMITTER RELOCATION

  CGC #335 reprinted the following FCC description of
  a transmitter change proposed by KRCK(AM), Burbank:

  "MOD OF CP TO CHNG POWER AND ANTENNA SYSTEM"

  Howard Fine researched this item and discovered that KRCK is
  proposing an outright transmitter relocation to the KDIS(AM)
  site.  We have confirmed his finding.  So, the FCC description
  of the proposal is definitely misleading.

  One KDIS official writes, "We have discussed some rudimentary
  ideas concerning the concept and feasibility of co-location
  with some local allocations.  (However), we do not have an
  agreement in place that will allow KRCK to co-locate with KDIS."

  MINIATURE ROBOTS

  A miniature robot the size of an ant has been developed by
three Japanese companies.  It weighs only one one-hundredth of
an ounce, and moves at speeds of up to six inches per minute.

  But that's not all.  Each robot has a pair of connectors on
both sides that can be linked up with other robots for more
extensive assignments.  They can then crawl into the tiniest
of gaps around bundles of wires or pipes to make inspections and
possibly even make repairs.  Japanese scientists also plan to
develop similar micro-robots with higher speed motors and even
more advanced problem detecting sensors.
