FARS Meeting Programs - 2011 [2010] [2009]

Friday January 21, 2011 - FARS/PAARA Winter Banquet

FARS/PAARA Winter Banquet 2011

Gerald (Jerry) Dieter Griffin
MD, PharmD, K6MD

Jerry, who is a medical doctor, has served over 40 years in the US ARMY and US ARMY Reserves. He has been deployed to war zones three times (twice to Iraq and once in Kosovo). He has been active in amateur radio since 1958 and has 329 confirmed DX countries. He operated DX from a number or unusual locations. He was inducted into the CQ Amateur Radio Hall of Fame in 2008. At age 70, he is still active in immunology research.

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 along with other articles in our documents section.

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
Steve Stearns, K6OIK

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.

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. Happy Holidays!

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.
