Plan, Organize, and Enjoy a DXpedition

Rich Seifert, KE1B

Recently returned from an DXpedition to Anguilla.

Rich (KE1B) and Anna (W6NN) have raised Holiday DXpeditioning to an art form. Over the past 4 years, they have traveled to numerous destinations in the Caribbean, the Mediterranean, and coastal Africa in search of fine food, great beaches, and massive pileups. Rich will explain the logistics involved in arranging their excursions, along with a detailed look into his “DXpedition-in-a-Box” portable radio system.

Combining lots of photographs from their travels, stories of their adventures in searching for exotic cuisine and fun, and insight into working the pileups from “the other side,” this talk will show you a fun way to enjoy our hobby, and possibly encourage you to venture out on your own DXpedition.

Rich Seifert (pronounced SEE-furt)(KE1B) has been a ham since 1968, when he was first licensed as WN2DLJ in New York City. He obtained his Extra Class license in 1970. After moving to Massachusetts and changing his call to KE1B, he went QRT in 1982, focusing on his professional career. Although he didn't make a QSO for 25 years, he remembered to keep his license current. He rekindled his interest in the hobby in 2007, and has been very active ever since. Rich is primarily a DX'er and contester, but has been known to chew the rag and operate QRP from time to time.

Anna Sombor (pronounced SHUM-bore) (W6NN) was first licensed in 2009 as KE1BYL, then obtained her Extra Class license and current callsign in 2011. She is primarily a contester and DX'er. She learned the code in the fall of 2010, and immediately won the first-ever CW Rookie Roundup, followed by a repeat win in 2011. She holds the all-time YL record for the California QSO Party, along with numerous other contest achievements.

Rich and Anna also contest in the multi-op category as the K6MMM monkeys (Monkey-Monkey-Monkey). Anna is primarily responsible for initiating our Holiday DXpeditions.

CW Skimmer and the Reverse Beacon Network: What It Can Do for You Even If You Never Operate CW

Bob Wilson, N6TV

Bob Wilson (aka “TV Bob”) explains CW Skimmer and the Reverse Beacon Network. These two elements work together to provide real time monitoring and reporting of HF propagation path openings. The resulting database represents real time “nowcasting” as opposed to “climatological” propagation predictions like VOACAP gives. Hence the data is useful to operators as opposed to communication planners.

Bio:

Bob Wilson, N6TV, is an active CW contester and Win-Test logging software supporter. Licensed for over 40 years, Bob competed at the World Radiosport Team Championship (WRTC) in San Francisco (1996), Slovenia (2000), and Moscow (2010). He earned numerous Top Ten finishes in the CW NA Sprints from his home station in Silicon Valley, a small suburban lot with a single tower loaded with monobanders. He finished first in the September 2014 CW NA Sprint. Bob was an early adopter of the Perseus SDR and CW Skimmer, and has recently been analyzing signal reports using data from the Reverse Beacon Network (RBN). He joined K2KW's original "Team Vertical" group (6Y4A, 4M7X), and has been a member of the multi-op teams at HC8N, K3LR, and W7RN. Bob finished first in the 2013 ARRL CW Sweepstakes Contest, operating at W7RN.

Ground is A Myth!

Kristen McIntyre, K6WX

Ground is something you stand on, but in an electrical sense, the meaning is much less clear. When it comes to Hams and ground, things get really confused. We drive rods into the earth, but why? Let's take a look at whether any of this makes sense, and what theory tells us about “ground”, and if it exists in any sensible way at all. We'll talk about DC grounds, RF grounds, and even about gravity.

Bio:

Kristen McIntyre, K6WX, has been interested in radio since she was five years old. As a youth, she built many radio kits including her favorite: a one-tube radio kit.

Kristen started in Amateur Radio by getting her Technician’s license in the late 1970s while an undergraduate student at MIT. She built a 2-meter repeater with an autopatch to use while on campus at MIT. Kristen now holds an Amateur Extra class license and also is licensed in Japan as JI1IZZ. She is active on 2 meters, 1.2 GHz, and HF. She built an Elecraft K2 while on vacation. Kristen likes to work HF mobile using the K2 and a hamstick. She also operates from her apartment using an Icom IC-7600 driving an Ameritron AL-811H power amplifier into a homebrew helical vertical dipole. She loves to chase DX using mostly CW, and works contests from time to time.

Kristen’s professional career has been diverse. In the early 1980s, she designed high-power linear amplifiers. She spent five years in Japan, architecting and designing precision analog test systems while learning the Japanese language and culture. Kristen returned to the U.S. and has worked at or consulted for Silicon Valley tech firms. At Adobe Systems, she architected PostScript Level 2 and its RTOS underpinnings as well as AppleTalk networking for PostScript printers.

Maximum Permissible Exposure Limit versus Near Field Radiation from a 2-Meter Mobile Antenna

Keith Snyder, KI6BDR

Every ham knows that a car is a Faraday cage that protects you from RF exposure, right? Wrong! Every ham knows that dipoles and monopoles have no end-fire radiation, so if you sit directly under the whip on your car's roof, you are in a null and therefore safe, right? Wrong!

Ever since the FCC published OET Bulletin 65 and Supplement B in 1997, all Amateur Radio operators have been required to do station evaluations to assure that RF exposure does not exceed maximum permissible exposure limits. But short of doing direct measurements, how safe are you inside your car when you operate on 2 meters through a roof top monopole?

Keith Snyder, KI6BDR, has done extensive computer calculations of electric field, magnetic field, and power density field inside the typical car. The answer may surprise as Keith shows how to avoid winning a Darwin Award for making cooked ham. Tonight's presentation will show the power of computers to safely harness your RF power.

This membership meeting is our nomination meeting where we are nominating directors for the FARS board of directors. Members are encouraged to attend so they can make nominations for the board of directors.

The TBJ-1: A Tri-Band Antenna for 2 meters, 220 MHz, and 70 cm without Radials

Ed Fong, WB6IQN

[Meeting scheduled in Room 32 this month]

Ed Fong, WB6IQN, has done it again! Ed presented his dual-band DBJ-1 and DBJ-2 antennas to FARS ten years ago, in October 2005. These antennas became highly popular after their publication in QST (DBJ-1 in February 2003 and DBJ-2 in March 2007) and CQ (Summer 2012).

Not content to stop, Ed, decided to attempt a tri-band version. The goal was to make a slender antenna that would fit inside a single PVC pipe with nothing protruding. Ed wrestled with numerous design concepts before finding a novel solution. The tri-band TBJ-1 operates on 2 meters, 1.25 meters, and 70 cm. Ed has also made custom variations for different three bands.

This membership meeting is our election of directors meeting where we elect new directors and re-elect ongoing directors for the FARS board of directors. Members are encouraged to attend so they can participate in this important function.

Geomagnetic Disturbances

Richard J. Lordan,
Professional Engineer and Senior Technical Executive for Power Delivery and Utilization,
Electric Power Research Institute (EPRI)

Richard Lordan will speak about EPRI's research in Geomagnetic Disturbances (GMDs). Radio Amateurs know that the sun affects ionospheric radio wave propagation. The sun also creates geomagnetic disturbances, a source of HF radio noise. But GMDs also create voltage surges in power transmission lines capable of knocking power utilities off the grid and causing power blackouts.

EPRI is a leader in power industry research to understand, monitor, and mitigate the effects of GMDs on power systems. Richard Lordan will talk about the network of magnetic sensors that the power industry has deployed to monitor GMDs. His comments on the protection of power system towers, lines, and equipment will suggest steps you can take to protect your station equipment during geomagnetic storms.
