  MORE ON 8-VSB vs. COFDM

  The latest edition of Tech Note carried two stories of
interest to the DTV community:

  The Department of Defense has reportedly raised concerns about
8-VSB as it is currently implemented.  Outdoor antennas are
vulnerable in natural/unnatural disasters, and 8-VSB has trouble
reaching indoor antennas.  Therefore, DOD reasons, 8-VSB will
limit the government's ability to communicate with its citizens.

  The second item of interest is a letter from Mark E. Hyman,
VP Corporate Relations, Sinclair Broadcast Group.  He writes,
"If you and your organization are uncertain of your position
(on 8-VSB vs. COFDM), but believe that this matter is deserving
of public scrutiny, then I urge you to immediately notify the
FCC that you support a public comment period."  See his
complete letter at:

  PART OF SIGNAL HILL WIPED CLEAN OF RF

  Part of Signal Hill near Long Beach has been wiped clean
of RF communications sites to make way for condominiums.  That
has caused ongoing problems for KLON(FM), 88.1 MHz, which was
one of the evicted tenants, but it also caused massive problems
for the KACD/KBCD microwave feed as the following home-brew web
page by Mike Callaghan shows:

  LAND-MOBILE INTERFERENCE SOLVER NEEDED

  Who would you recommend to solve land-mobile interference
problems?  Not that we have any yet, but an FM broadcast station
is planning a series of test transmissions from a new site in
southern California, in January, and we need to know who to call
in case interference is caused.

  Please send a short note with your recommendation to
Bob Gonsett, editor of the CGC Communicator newsletter:

  rgonsett@connectnet.com 

  Thanks!

  KNSD-DT IS BORN

  KNSD-DT, CH-40, San Diego, went on the air at 10:58 a.m.
on Wednesday, December 8th.  ERP is 18.2 kilowatts; transmitter
is on Mt. San Miguel.  Testing is in progress, but programming
will be up most of the time.  When we are not broadcasting in HD,
we will be upconverting our standard definition channel.  (The
only High Definition programming available on NBC right now is
"The Tonight Show With Jay Leno.")

  Congratulations to Bob Vaillancourt (Engineering Manager,
KNSD TV/DT) and his engineering staff for a job well done.

  Oscar Medina, KNSD

  DTV INTERFERENCE TO LAND-MOBILE?

  I was wondering if your readers have any reports of problems
caused to land-mobile installations located in the proximity of
DTV transmitters?  If problems have been reported, what steps
were taken to correct the interference?  Were the corrections
completely successful?

  I am working with the U.S Forest Service in developing a
communications site master plan that will include new DTV
installations, and would like to know if there are some issues
learned in your area that we should consider in the plan.

  Information relayed to me indicates that DTV has rendered
some land-mobile communications inoperable.  Any information or
documentation you may send my way would be greatly appreciated.

  Thanks, Jim Lencioni, cpi@powernet.net

  USE OF DIGITAL CAMERAS IN HIGH RF ENVIRONMENTS

  Has anyone had any experience with the Kodak 265 (260, or
290) digital cameras in high RF environments?  Places like
radio rooms FILLED with transmitters, multi-high powered
transmitter buildings, ATU/AM tower bases, roofs or tower tops?

  A client is considering the purchase of one of these
high end cameras for a variety of work, including site
inspection/due diligence work, and would prefer to learn
about any RF related aberrations before buying.
