Tools and Tips for Transmitter Hunting?
Don Ferguson, KD6IRE
Don Ferguson, KD6IRE, describes the tools and techniques
used by amateur T-hunters to locate RF emission sources.
Don will shows and demonstrates antennas and other tricks
such as the use of beams, loops, body fade, attenuators,
waveguide tubes, Doppler DF, phase interferometers,
TOA (time of arrival), antennas and special receivers —
all to locate a hidden “Fox Box,” a low power transmitter.

Magnetic Loop Antennas — The Best Kept Secret
in Amateur Radio
Eric Norris, WD6DBM
Eric Norris, WD6DBM discusses the magnetic loop antenna.
Magnetic loop antennas behave differently from dipoles and monopoles.
Everything about a loop is different — its impedance,
directivity pattern, how these depend on height above earth,
earth’s conductivity and dielectric constant.
Also, the sensitivity of loops to near field noise pickup is different.
Now for the good news.
In nearly every aspect, the difference gives the advantage to the loop.
Magnetic loop antennas do not have to be as high or as big to perform great.
Eric will explain the ins and outs of using magnetic loop antennas.
You can find the presentation

Conjugate Matching Disproved
Steve Stearns, K6OIK
A popular book by Walt Maxwell, W2DU, called “Reflections”
presents an incorrect theory of impedance matching.
Steve Stearns, K6OIK, will show what’s wrong
with Walt Maxwell’s concept
of transmission lines and why Maxwell’s idea of conjugate matching
fails to do the very thing Maxwell claims it does —
provide maximum power transfer from a source to a load through a line.
In working out the correct solution to the maximum power transfer problem,
Steve succeeded where Maxwell failed, and found the correct match solution
for maximum power transfer.
Be prepared to gain dB’s as Steve guides us through controversial
territory fraught with misconceptions, error and mistakes.
Also, before the regular program Dan Curtis, N6WM, talks
about “2-meter Simplex Frequencies in Danger.”
The Northern Amateur Relay Council of California (NARCC)
is planning to take half of the available 2-meter simplex frequencies
and reassign them to repeater use.
A petition is being circulated among local Radio Amateurs
that objects to NARCC’s proposed plan.
Dan Curtis, N6WM, will explain NARCC’s rationale and
how 2-meter band operations would be affected.
He will also explain the grass-roots petition
to counter NARCC’s proposed action.

Premature Antenna Destruction, Its Causes and Cures
Rick Huisman, N6DQ
Why would any ham in their right mind take down a magnificent
HF yagi antenna on a 65 foot mast, sell the antenna,
and have the tower taken away?
For the lure of life on the beaches of Southern California?
Uh, well yes, that’s exactly what happened.
Come and learn how Rick, N6DQ, quickly saw
the error of his ways...but not before the great antenna
and mast went bye-bye.
But more importantly, learn how Rick turned this ham tragedy
into a ham triumph!

Automated Antenna Design and Optimization
Dr. Jason D. Lohn, Associate Research Professor
Carnegie Mellon University
Silicon Valley Campus
Current methods of designing and optimizing antennas by hand
or computer are time and labor intensive, allow limited complexity,
and require significant expertise and experience.
Evolutionary design techniques can overcome these limitations
by searching a design space and automatically finding effective solutions
that would ordinarily not be found.
Dr. Lohn discusses automated antenna design optimization that produced
the “evolved” antennas that flew on NASA’s
Space Technology 5 (ST5) mission,
the first ever artificially-evolved objects to fly in space.
He also describes the software tools that he and his colleagues
developed to automate the design of these evolved antennas.

Amateur Radio in Ethiopia
Jim Deloach, WU0I.
United States Foreign Service
Have you ever wanted to be that rare DX station and
be on the other end of the pile-ups?
Have you ever wondered what it would be like to be in a country
where you can count the number of amateur radio operators
on your fingers and toes,
instead of being yet another Silicon Valley Ham?
Come hear Jim DeLoach,
a United States Foreign Service Officer
recently returned from Addis Ababa,
talk about Amateur Radio in Ethiopia!
Ethiopia should be Ham Radio paradise,
but shipping and import constraints,
high noise levels in this crowded third world city,
and most importantly suspicious and unmotivated local officials
make hamming a challenge.
Learn how Jim overcome these obstacles,
what it was like to be that rare DX station for a change,
and how the Ethiopian Amateur Radio Society (EARS) club station,
ET3AA, and its founder Sid, ET3SID,
have played a critical role in keeping Ethiopia on the air!

Predicting HF Ionospheric Propagation by Ray Tracing
Did you hear Steve talk about using VOACAP to predict
HF propagation paths at the FARS February 26, 2010 meeting.
This is the sequel.
Ionospheric ray tracing is a method entirely different
from VOACAP for predicting HF propagation.
In many cases, ray tracing gives better insight
into propagation effects than VOACAP.
Steve will explain why and show real time examples
using a program called Proplab-Pro 3.0.
Proplab-Pro is priced within reach of the serious DX’er.
Steve will show what it can do that VOACAP can’t.
Steve will talk about the limits and future of both approaches
to the problem of prediction.
Friday September 23, 2011 - Membership Meeting
This is your time to shine.
Bring your amateur radio project to this meeting to
show and describe to our audience.
Everyone has a few minutes to explain and describe
Then the audience votes on the best ones to award prizes.
The following prizes are awarded:

CQP Expedition to Trinity County
Joanna Dilley K6YL and
Kristen McIntyre K6WX
From a cabin in beautiful Lewiston, California,
Joanna and her pals N6DQ, K6WX, and K6RHO activated Trinity County
for the California QSO Party (CQP).
Trinity County is north of Mendocino County,
west of Shasta County, south of Siskiyou County,
and east of Humboldt County.
Lewiston is a beautiful historical gold mining community
on the Trinity River by Lewiston Lake and home of Bigfoot.
Come and hear Joanna tell about the adventure and excitement
of setting up and operating CQP in Bigfoot territory!

Ham Radio Holiday Treats
Howard Califf W6HOC
Ham Radio Outlet
In time for the holiday season, Howard Califf, W6HOC,
shows the newest and popular amateur radio gear.
Be sure to attend to find out about special holiday promotions too.
This meeting is our annual membership meeting
where we are electing directors to the board of directors.
Members are encouraged to attend and exercise their right to vote.

Moonbounce and Meteor Scatter for the Masses
Eric Norris, WD6DBM
It used to take big antennas, big amplifiers,
and a lot of patience to work EME.
Now with the WSJT revolution, many hams may already
have the equipment they need to get ’er done.
Eric will show us how.
