  SATELLITE RADIO CLEARED FOR THE U.S./MEXICAN BORDER ZONE

  There is now a signed agreement between the U.S. and Mexico
covering the Satellite Digital Audio Radio Service ("DARS") and
various terrestrial uses in the 2310-2360 MHz band.  No longer
will the two U.S. DARS providers (Sirius and XM Satellite Radio)
fear having holes shot in their coverage patterns near the border.

  This is a major step forward for DARS, and a credit to the ne-
gotiators on both sides who worked through many difficult issues.

  KNSD-TV, SAN DIEGO, TO MOVE DOWNTOWN WITH STREET-SIDE STUDIO

  After 35 years in Kearny Mesa, KNSD, the NBC owned and
operated TV station in San Diego, has reached an agreement
to move to a new downtown location at 225 Broadway.  The
move is planned for the spring of 2001 and will include a
unique street level studio.  Like the Today Show, some broadcasts
will move outdoors to Horton Square for various activities.

  STEVE BLODGETT RETURNS TO LOS ANGELES

  KNX(AM) and KCBS-FM are pleased to welcome Steve Blodgett
back to Los Angeles.  Steve will fulfill the newly re-created
position of Director of Technical Operations for KNX and KCBS-FM.
Steve and I will be sharing administrative duties for a few weeks
while he gets his "sea legs" aboard this grand old ship, at which
point I will gladly settle back into the job I was hired to do.

  FIREARMS AND FCC FIELD INSPECTORS

  Re the letter from Lew Collins in CGC #401 and his
recollection of a Commission engineer armed with a revolver,
I was on the FCC's field enforcement staff in the mid-1960s
and remember very clearly that FCC agents were PROHIBITED from
carrying firearms and it was made very clear to us that we
could be summarily fired for doing so.

  Has Lew's memory been filtered through several fictional
movies allegedly depicting FCC's WW-II activities?

  ANOTHER VOTE FOR THE FOUR BAY BOW TIE

  Re the report that the four bay bow tie antenna worked best
for DTV reception (CGC #402), I am not surprised considering
(in part) the effect of the screen removing pattern perturbation
from the mounting structure.

  I actually constructed several large aperture (>20 feet) VHF
dishes to try to eliminate ducting, which arrives (usually) at
plus a degree or three, and had a lot more success than the
textbooks predicted.  A fun project for younger days, with
chicken wire, redwood furring strips, and a guy and turnbuckle
through eye screws for focusing.

  HIGH GAIN IN UHF-TV PREAMPS ENCOURAGES SELF-OSCILLATION

  When I was with the FCC, I investigated a complaint of
interference to a 440 MHz ham radio repeater input.  The source
was found to be an oscillating mast-mounted preamp in the
Sacramento area.  Presumably because the preamp/oscillator was
attached to a high-gain TV antenna, the radiation reached from
Sacramento to Mt. Diablo -- a distance of about 50 miles.

  My feeling is that these preamps are needlessly high in gain
(20-30 dB is not uncommon), which makes them unstable with aging,
temperature, etc.  If the gain was reduced to a more reasonable
level (that required to overcome the loss of the downlead and
a splitter or two), self-oscillation would be less likely.

  POWER LINE RFI IMPACTS THE AM BROADCAST BAND

  I have worked for a public utility in the midwest and spent
a significant amount of time doing RFI work.  RFI has been an
issue to listeners of the AM band in the US.....

  My experience tells me that you can expect an increase of
(power line) RFI.  Existing systems are getting old, and utilities
are unwilling to replace older, noisy systems unless forced to do
so.....  While the utility I worked for did a reasonable job of
trying to address and repair specific instances of RFI, I also
observed the impact of increased competition on budgets, and
reluctance to do more than small scale changes.

  TWO REPUBLICAN CONVENTIONS?  SO SAYS THE FCC

  CGC #403 mentioned the "Republican Convention in Los Angeles."
I thought that the Democrats were having their convention in L.A.

  Sam Lane (and others)

  Ed Comment:  You are correct.  The error originated in
the FCC's Daily Digest for 7/21/00 and we failed to catch it.
According to the Digest, the Republicans are having two
conventions, one in L.A. and one in Philadelphia!  Fortunately,
the typo did not propagate to the text describing the L.A.
frequency coordination process which may be viewed at:

  WRKG TOWER DOWN, A 500 FOOTER

  On July 20, a suspected funnel cloud toppled the 500 foot
tower leased to WRKG-FM, 100.5 MHz, Newberry, FL.  The tower
has been deemed a "total loss" and will be replaced.

  Fortunately, no one was injured and the transmitter shack
survived.  Of the four coax lines shown coming out of the building
in the URL below, only one belonged to WRKG.  The others fed
paging antennas.
