  KGTV ON THE AIR WITH DTV

  The first DTV transmissions in the San Diego area are now
complete.  Congratulations to Margie Baldwin and her crew at
KGTV for the fine accomplishment!

  According to Margie, KGTV carried Monday Night Football
for September 13, 1999 in three formats: two in DTV (standard
definition on Channel 25-1 and high definition on Channel 25-2),
and conventional NTSC on Channel 10.

  While the DTV transmitter operated at reduced power due to a
faulty component, the digital broadcast appeared to be successful
in all other respects, and the next Monday Night Football is
expected to be transmitted at full power.  For more information,

of KGTV-DT, Channel 25, San Diego."

  COFDM VS. 8-VSB: UPDATE

  While the current implementation of 8-VSB remains woefully
inadequate for widespread consumer acceptance (DTV signals are
not receivable on many indoor antennas), it remains to be seen
whether the new decoder chips will be sufficiently robust to
solve the problem.  Read the latest chapter in this fascinating
story in an article prepared by Nat Ostroff, V.P. New Technology,
Sinclair Broadcast Group:

  EMERGENCY SIGNALING ON 87.9 MHZ?

  The FCC has announced that Federal Signal Corporation has
filed a Petition for Rulemaking (RM-9719) to "authorize the
transmission of Emergency Signals on channel 200."  If channel
200 means 87.9 MHz, there would be genuine interference concerns
for FM stations operating on 88.1, 88.3 and 88.5 MHz, and for TV
stations on Channel 6.  Comments are due at the FCC by mid-
October.  The FCC announcement is available at:
