June 14 Meeting

The next WVARA meeting will be held in-person on Wednesday, June 14, in Meeting Room 3 at the Silicon Valley Chapter of the American Red Cross, 2731 N. First Street at Plumeria Drive (southwest corner) in San Jose.   Social time begins at 6:40pm with the formal meeting starting at 7pm.  If you haven’t been to the Red Cross in a while, “talk-in” is usually available on the Association’s repeaters. Best choice would be 2m/220.   

BTW, a half dozen of us meet nearby for dinner prior to the meeting at 5:30pm nearby at Disn-N-Dash (2551 N. 1st St. San Jose):  https://dishdash.com . Feel free to join us.


Meeting Topic:  AREDN (Amateur Radio Emergency Data Network) —  Come hear about RF Microwave Networking here in the South Bay Area.  We will learn about what exists now, and how AREDN can be expanded for experimentation, community support, and emergencies.  This will also be an opportunity for WVARA members to ask questions about setting up multi-Mbps systems at home, portable, and at key community locations.

Our speaker, Jim Moss, N9JIM, is working with a small group of hams to establish a microwave backbone around the SF Bay Area — in particular the South Bay. The first mountaintop station was established in 2013 on 3GHz and demonstrated IPphone & text messaging to flyaway portable setups. In 2022,  Jim helped establish a 5GHz mountaintop node with AREDN firmware.  BTW, Jim also holds the current (2020) 122GHz distance record holder with K6ML & KB6BA. They operated from Mt Umunhum (near San Jose, CA) to Mt Vaca (near Vacaville, CA) a distance of about 80 miles using 18″ dishes and about 1mW. Jim is also active on 1.2GHz EME (Earth-Moon-Earth) communications using 500w and a 1.5m dish.  Very cool!

If you can’t wait until June 14 to learn about AREDN, then check out the AREDN website at:  https://www.arednmesh.org/


Regarding our June 14 meeting, three things to remember:
• Since the west side entrance to the Red Cross Building is always locked, we recommend entering the Red Cross Building through the main entrance situated on the north side of the building.
• The Red Cross locks the main entrance at 7pm sharp, so please come early in order to get access to the building.  
• We will be in Meeting Room 3 — about 100 feet from any entrance.  As a result, late comers who knock on an outside door won’t be heard from our meeting room.  If you need help getting in the door, you can my cellphone:  408-636-6172.

April 12th WVARA Meeting

First Street at Plumeria Drive (southwest corner) in San Jose.   If you haven’t been to the Red Cross in a while, “talk-in” is usually available on the Association’s repeaters.

 Kristen McIntyre, K6WX

This month’s speaker will be Kristen McIntyre, K6WX, who will discuss “A Wire in the Air: What Matters Most”.  The magic of radio happens when we couple RF into the fabric of spacetime. We do that with an antenna. These devices are simultaneously simple and complex. It’s easy to get lost in the theory or fooled by the latest anecdote. Let’s look at what’s important in antenna choice and design. There are things that matter more than others, and it’s never perfect. And a bit of theory will guide us. Radiation resistance, loss, pattern gain, terrain, polarization, coupling, loading – they all play a role. Join us to find out what happens and what matters when we put a wire in the air.

Social time will begin at 6:45pm, with greetings and club business at 7pm followed by Kristen’s presentation.   Kristen has been interested in radio since she was about 5 years old.  She started in Amateur Radio in 1979 getting her ticket while at MIT.  Kristen has worked in many diverse areas from analog circuit design to image processing to starting and running an ISP.  She is currently working at Apple in Core Networking, and spent many years at Sun Microsystems Laboratories where she was researching robustness and emergent properties of large distributed computer systems.  She is a long time denizen of Silicon Valley and has worked at or consulted for many of the usual suspects.  Kristen is an active ham and loves to chase DX on HF with her Elecraft K2 which she built while visiting her mother in Florida.  She is ARRL Pacific Division Director, president of the Palo Alto Amateur Radio Assoc., the Q&A columnist for Nuts and Volts magazine, and is active in many local clubs.  Kristen was recently inducted into the CQ Amateur Radio Hall of Fame.

Three things to remember:

  1. Since the west side entrance to the Red Cross Building is always locked, we recommend entering the Red Cross Building through the main entrance situated on the north side of the building.
  2. The Red Cross locks the main entrance at 7pm sharp, so please come early in order to get access to the building.  
  3. We will be in Meeting Room 3 — about 100 feet from any entrance.  As a result, late comers who knock on an outside door won’t be heard from our meeting room.  If you need help getting in the door, you can call Tim, KN6FGH, at 408-929-9311.

Although we will be meeting in person, Kristen’s presentation will also be streamed via Zoom.  Zoom instructions will be sent via WVARA reflector and can likewise be obtained by contacting K6EI — his email is available via QRZ.

February 8 WVARA Meeting

This month’s WVARA meeting will be held in-person at 7pm on Wednesday, February 8, in Meeting Room 3 at the Silicon Valley Chapter of the American Red Cross, 2731 N. First Street at Plumeria Drive (southwest corner) in San Jose.   If you haven’t been to the Red Cross in a while, “talk-in” is usually available on the Association’s repeaters. Best choice would be 2m/220.  

This month’s presenter is none other than our own Steve Sergeant, KC6ZKT.  Steve will cover some of the highlights of our recent Winter Field Day adventure, followed by a fascinating presentation, “The Model-T of Computers”.  This talk explores two ground-breaking examples of technologies that changed our society. Each one changed important things about how people lived and how civilization worked. As we evolve our technical skills, can we resist the social changes that they bring? Should we?

Steve Sergeant holds an Amateur Extra class license, and is a third-generation ham.  He has held lead technical roles for companies that brought digital audio to the music industry and digital video to the largest television broadcasters. Steve currently works as a senior staff engineer at Dolby Laboratories, helping manufacturers design the next generation of high-end audio/video equipment. His colleagues there like to call him their “expert generalist.”

BTW, several of us meet for dinner prior to the meeting at 5:45pm nearby at Disn-N-Dash (2551 N. 1st St. San Jose):  https://dishdash.com  Some WVARA members also dine at Panera Bread a few miles further to the south at 503 Coleman Avenue at Autumn Parkway at the San Jose Market Center.  Feel free to drop by either location for dinner.

Another Winter Field Day in the books for WVARA

The weekend between 1/28/and 1/29/2023 marked another successful Winter Field Day endeavor for our association.

Originally scheduled to be held in Henry Coe Park, bad weather forced us to “relocate” to Mt. Madonna County Park.

The day started cold and foggy…

But we set up successfully and celebrated appropriately:

more setup:

Green light @ 11:00 AM PST on 1/28/2023:

And, of course, a gift from mother nature to make the experience truly unforgettable:

This was my first Winter Field Day but I highly recommend it to all the WVARA members. Join us next year! You will be glad ! ! !
