  NEVADA PIRATE OPERATOR GETS STA
  One Nevada pirate broadcaster has reportedly received a
Special Temporary Authorization (STA) from the FCC to get back
on the air.  The Pahrump Valley Times of Nevada reports that
Senate Majority Leader Harry Reid, D-Nev., intervened with the
FCC to allow the unlicensed broadcaster back on the air.  The
pirate's operation was raided and shut down by the FCC last June.
  According to the published account, the pirate can operate
with the STA until he can apply for an LPFM license in a future
filing window.  What a deal.  What a miserable precedent.

            LETTERS TO THE EDITOR - BARBED WIRE RADIALS
******************************************************************
  WOR(AM), NEW YORK, ONCE USED BARBED WIRE RADIALS
  WOR(AM), New York, once used barbed wire radials.  I think
it was the late 70s, early 80s.  The [old copper] radials were
being stolen from the east side of our old array where the
thieves could work unnoticed.
  The copper radials were replaced with regular barbed wire.
Not only was the scrap value nothing, but having your hands
sliced up served as a hell of a deterrent.
  Of course, the barbed wire deteriorated fairly soon -- as
our old transmitter site was built on a dump and the ground
water tends to be brackish -- but after the perpetrators
stopped bothering us, WOR went back to using copper.

******************************************************************
  MORE ON WOR
  The station that used barbed wire radials was WOR, NYC,
and the engineer who tried it out was Orville Sather.  That
particular array was demolished just last month [CGC #776 video]
to make way for a golf course.

******************************************************************
  ABOUT THE FCC'S APPROVAL OF BARBED WIRE AT WOR
  The idea for using barbed wire arose after a substantial
portion of the WOR ground system was stolen after having been
replaced following one of several fires in the trash dump
underlying the site (the copper radials had been destroyed by the
fire). I do believe that the barbed wire was galvanized to assure
as high conductivity as practical, and I seem to recall that
barbed wire was used rather than smooth wire as it was about
impossible to pull a length of it out of the ground.
  I also seem to recall that the Commission's reaction was to
approve the substitution with the condition (on the license) that
the common point impedance be measured annually.  What they were
concerned about, of course, was potential deterioration in antenna
radiation efficiency.  With a network in place to set the common
point impedance, the FCC's measurement requirement would not
really detect such deterioration, but the RSS of the element base
currents would.  What the records actually showed over succeeding
years I do not know, but if anyone finds out, I would be
interested.

******************************************************************
  ROBERT SILLIMAN'S ROLE IN THE WOR BARBED WIRE PROJECT
  In response to your question, Robert Silliman did work on
the barbed wire radials for WOR, but did not publish a paper
on the project.  He wasn't much into giving papers, but he was
known as a consulting engineer who would always answer questions
and help other engineers out with problems....
  In the New York area, one would expect to have problems with
barbed wire unless it was galvanized, and I think that Robert did
specify galvanized barbed wire. In the desert, un-galvanized wire
might work, but galvanized wire would be better because the
conductivity is better. As you know, copper conductivity
is 3.57 better than zinc.
  Finally, if I were to use galvanized wire in the ground, I
would consider adding a sacrificial ground (Mag rod) to keep the
galvanized coating on the wire from deteriorating.

  COPPERWELD RADIALS AS AN ALTERNATE SOLUTION
  At LBA, we design most of our ground systems in 40% Copperweld
(TM) #10 wire.  This stuff has virtually no scrap value, and there
is insignificant AM loss due to the copper cladding being several
skin depths thick at AM frequencies.  It is stiff enough that
anyone trying to pull it up should think twice about it being
copper.  It is also more resistant to breaking from earth
movement and vehicular traffic, as well.

    LETTERS TO THE EDITOR - GERIATRIC ELECTROLYTIC CAPACITORS
******************************************************************
  A BIT OF HISTORY ON FAULTY SURFACE MOUNTED CAPACITORS
  The capacitor saga [CGC #779, "Stories of Interest
from San Diego SBE Chapter 36"] dates back to about 1998 and
the wide use of surface mounted electrolytics.  Those parts have
a time and temperature rating.  The ones supplied in most gear
do not have the most generous ratings.  While we deal with Sony,
Panasonic, JVC, etc., their original board assembly may all be
done at one outside vendor.  Thus, plenty of gear was built
with marginal capacitors.  I first ran into this with Panasonic
DVC-Pro recorders.  One audio card that was troublesome had 50
of the beasts on it.
  The best way to test for bad capacitors is with a Capacitor
Wizard that uses a high frequency to measure reactance.  It works
fine testing caps with no need to unsolder.
  Roy Trumbull, roy547 (at) msn.com
******************************************************************
  GARY STIGALL (FOX 6) REPLIES TO ROY'S LETTER
  The Panasonic DVC-Pros are the first and worst detected.
We tried Panasonic replacement kits and they didn't fix all
symptoms.  I decided not to test the capacitors, figuring that
we would have too many iterations of failure/remove/disassemble/
test/replace/reassemble/return.  Our rework guy could replace
400 caps per day, so I just said to heck with testing --
replace them all!
  It's been my experience that measuring in-circuit reveals
the problems in only one point in time and doesn't address future
cap failures.  In our case, we haven't had any symptoms in our
DVCPRO decks since the mass replacement of capacitors.

http://www.theinquirer.net/default.aspx?article=24596 (re Dell)
  All in all, it looks like bad electrolyte is the root cause.
In some cases it causes a reduction in capacitance value (which
changes circuit performance), in others it blows the tops off the
caps, in others the electrolyte eats its way out of the cap and
eats up the board.

  FCC SWEEPS VENTURA COUNTY
  FCC field enforcement is busy these days.  One inspector
[has] inspected all broadcast facilities in Ventura County this
past couple of weeks.
  He cleverly and independently visited the transmitter sites
noting lighting, marking, signage and fencing violations before
he visited the studios where he carefully and methodically
inspected Public Files, EAS records, and had each and every
station perform a live "On Air" EAS test in his presence.
  [The inspector] was well prepared to take down the best of
errant broadcasters.  Watch for FCC announcements at this URL:
<http://www.fcc.gov/eb/FieldNotices/>.
  [A full sweep of another market] is suppose to take place
in the next couple of weeks.  [The inspector] also hit Pep Boys,
Circuit City and other retail sales places in Ventura that are
marketing wireless products that are not FCC approved.
  Chuck Hastings, crh-bes (at) juno.com
  [At the request of the FCC, this letter has been edited to
remove the name of the field inspector and the name of the next
market planned for inspection, so be prepared!  -Ed.]

  NY SENATOR TAKES AIM WITH BILL BANNING "WALKIN' AND TALKIN'"
  New York was an early leader in banning the use of hand-held
cellphones by motorists, and now a state lawmaker wants to extend
that ban to those on foot who use wireless phones, iPods,
Blackberries and similar devices while crossing city streets.
State Senator Carl Kruger says the distraction caused by wireless
devices has pedestrians getting killed by walking into speeding
cars, buses and each other.
  The idea of prohibiting the use of cellphones, display
devices, two-way radios etc. from ANY moving vehicle is gaining
momentum in a few states.  This is a different story not
discussed at the URL below, and may reflect massive over-
regulation.

emergencies [CGC #777].  Although several other states are
considering similar enhancements, 9-1-1 experts warn that the
initiative could result in information overload if the system
cannot handle the volume of data, or if dispatchers are not
trained to screen and accommodate the images.
