FARS Meeting Programs - 2005
Friday January 21, 2005 - FARS/PAARA Winter Banquet
Contesting in the Galapagos
by Trey Garlough,
Michael’s at Shoreline; Reservations required]
Trey was first licensed 1974
as WN4KKN. To say he is an "avid contester" would be
an understatement! Trey claimed the new single operator,
all-band world record in his 1999 CQ WW CW contest performance.
While he particularly excels at CW contesting, he can often
be found dabbling in SSB and RTTY contests as well.
He has been on many
- ZL9CI Campbell Is./Jan. 1999, TX0DX
- Chesterfield Is./March 2000
- 4W/N5KO East Timor/April 2000.
Even the casual contester will
certainly find Trey in his logbook under many call signs: 6D2X, 7J7YAA,
EA9UK, HC1OT, LU6ETB, K6O, KP2A, ON4UN, PJ9B and ZPØY,

Better Antenna Modeling through Advanced Computational
Dr. Keith Snyder
Summary: The use of computer modeling tools for antenna
design has exploded. Most programs available today use one of three
primary methods: the method of moments (MoM), finite element method
(FEM), and finite difference time domain (FDTD). These methods permit
the surface currents in a vehicle’s skin to be modeled and their effect
on antenna radiation pattern and impedance to be analyzed. In
addition, the newer tools actually animate the time-variation of the
electric and magnetic fields, thereby enabling an antenna designer
to view the radiation process. A VHF antenna will be modeled on a
Humvee by using the program FEKO. FEKO uses the same general method of
analysis as EZNEC, viz. the method of moments, but is more powerful.
EZNEC is limited to wires and doesn’t give fields or current
animation. FEKO handles general surfaces and dielectrics. FEKO Lite
is a free download that will get you started assuming you are
proficient at antenna modeling with EZNEC.

After the Big One!
Dru Anderson, KG6LAD
Amateur Radio’s role in providing communications for
disaster relief efforts.

Text messaging with APRS
Andreas Junge, N6NU
Did you know your 2 meter FM transceiver can be used for
sending and receiving text messages to or from other hams? That you can
send messages while mobile that non-hams can read on their computers?
The Advanced Packet Reporting System (APRS) permits sending packets
that contain more than just GPS coordinates. In fact, GPS coordinates
are optional; you can text message instead. Come and learn how to use
these little known capabilities of APRS.

Discussion of Field Day plans.

Location Based Services
Chris Verbil, N5CV
Chris Verbil, N5CV on technology for location based
services and new services that this technology makes possible.

Understanding HF Propagation and Prediction
Steve Stearns, K6OIK
We’ll review the interesting propagation effects that
govern HF band behavior, then launch into what propagation prediction
programs do. Understanding how different programs work is necessary
to being able to use such programs as operating aids. Imagine two neighbors,
each of whom must decide what clothing to wear outside today. Neighbor A
consults an encyclopedia to look up the climate of San Jose in July.
Neighbor B consults a newspaper for today’s weather forecast. Neighbor
C looks at his outdoor thermometer. Similarly, different propagation
prediction programs work by different methods, with different degrees
of predictive accuracy. Come learn what freeware and shareware tools
are available and what they can do.

Software Defined Radio
Kristen McIntyre, K6WX
Software Defined Radio, or SDR, replaces analog radio components
with digital signal processing. Many believe SDR to be the future of radio.
As computers increase in speed and power requirements decrease, what we
used to consider impossible is becoming commonplace. SDR is on this
path and this talk will explore several aspects of this emerging
technology which offers the promise of smaller, more flexible radios
with characteristics not realizable with conventional circuitry.
We will look at what SDR is, how it’s done, aspects of
modulation/demodulation, adjacent signal rejection, power requirements
and other topics.
Friday September 23, 2005 - Membership Meeting
Bring your favorite Amateur Radio project to the meeting
to share and describe to the audience. Share your experience and what
you learned from it. The audience chooses the best three projects for
First Place $40, Second Place $30, and Third Place $20.

A portable dual band J-pole antenna
Ed Fong, WB6IQN
Ed talks about the theory and construction
of a fully portable dual band J-pole which operates on VHF and UHF.
The basics of this antenna was presented by him in the Feb 2003
issue of QST. The advantage of this antenna is that it can be
rolled up and put into a large pocket until it is ready to use
which makes it ideal for ARES. This portable version
of the dual band J-pole will be featured in a coming QST.
You may want to read Ed’s
on the design of his antenna (DBJ-2). An article
on a previous version of this antenna (DBJ-1) is available
on the ARRL web site.

Introduction to Baluns
Paul Zander, AA6PZ
Baluns are an important and often misunderstood component
in RF transmission and measurement systems and circuits. However,
not all baluns behave the same. The different kinds of baluns and
their technical performance will be described.

Goodies for the Ham Shack
Howard Califf, W6HOC
Ham Radio Outlet, Sunnyvale
Just in time for the holidays. Howard shows new
and useful items for the ham shack - ranging from stocking
stuffers to larger station accessories, and possibly some
exciting new rigs.
