June Membership Meeting

WVARA’s next virtual meeting will be via Zoom at 7pm on June 9.  Our speaker will be Clint Bradford, K6LCS.  Clint’s presentation covers how to work amateur satellites with your HT. You do not need 100W of transmit power nor expensive antenna arrays to work the FM amateur satellites!  Many hams already have the necessary equipment to “work the birds.” This presentation will walk you through ALL the steps needed to successfully work several ham satellites.  (Since this presentation is 90 minutes, we will shorten our meeting’s normal introductions to allow more time for the presentation.)

Speaker Bio:  Clint K6LCS has been a ham since 1994, and found his niche in the hobby: working amateur satellites with minimal equipment and telling ALL about it! He has served a liaison between NASA, the ARISS team, and schools coordinating amateur radio contacts between the International Space Station and students (and orchestrated a wlldly successfulARISS contact).  Professionally, Clint was sales manager for ADI / Premier Communications / Pryme, worked for a Motorola commercial two-way dealer a couple of years, and for Ham Radio Outlet a couple more. He resides in Jurupa Valley, California, with his wife, Karen, and their rescued lab, Freja.

May Membership Meeting

Our May 12 speaker will be Kristen McIntyre, K6WX, who will speak on the topic of “SWR — Who Cares?” And will debunk some of the misconceptions and misunderstandings regarding the widest used measurement in ham radio — the Standing Wave Ratio.  Topics covered will include what it is, how it is calculated, what SWR actually measures, and what we should care about – including what an impedance match is, the impact of SWR on real transmission line loss, how to match a transmitter to a load and how to measure feedpoint impedance.  I’m looking forward to learning a thing or two!

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 Vice 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.

April Membership Meeting

Our April 14 speaker will be Brian Tanner, AG6GX, who will talk about “The Art of Voice Communications: Techniques for Technician & HF-class licensees”.  Brian will cover voice operating practices, including how best to format and communicate information for accuracy and precision via phone nets.  While this presentation will be especially useful for newer hams, even old timers may learn something new.

Bio:  Brian started by getting his Tech license in 1995.  After several years of activity on the VHF and UHF bands, Brian upgraded and became radioactive on the HF bands in 2013.  He participates in the Cupertino ARES group (CARES) as well as the city ARES net Cupertino_Net.  Brian also enjoys tinkering with hardware and recently built a 100W HF solid state power amplifier. 

WVARA’s Annual BBQ

It’s official.  Sunnyvale has opened their picnic facilities for summer reservations, and we’ve been approved for Baylands Park Pickleweed Picnic Area.  So mark your calendar for WVARA’s Annual BBQ on August 21 starting at 11am.  This coincides with the North America QSO Party / SSB, so we’ll be making contacts during our BBQ via a portable station.  (More details to follow.)

March Membership Meeting

Our monthly meeting will be next week on Wednesday, March 10, at 7:00pm via Zoom.  Zoom instructions will be emailed.

 
This month’s topic is one of interest to all hams.  Jim Aspinwall, NO1PC, will unlock the secrets of “Elmering in the Age of Devices” — how we can each get more involved in mentoring (i.e. elmering) — helping younger folks get excited about the magic of ham radio.  Jim points out that since “shop class” is a thing of the past, and Maker events are mostly focused on Arduino, robots and i-devices, there are few places for the average person to learn and really practice electronics except amateur radio.  Mentoring by those of us in the ham community is the key!   

Jim Aspinwall, NO1PC

Bio:  Jim was originally licensed as WN9GVF in 1970 and eventually upgraded to Extra in 2005.  In addition to a full career in the tech world, Jim served for 8 years as a volunteer firefighter/engineer, eventually transitioning that experience into working with the California Governor’s Office of Emergency Services as a telecommunications deployment specialist.  Jim has created and moderates a fantastic amateur radio Elmer forum on Facebook devoted to Amateur Radio Elmers (https://www.facebook.com/groups/AmateurRadioElmers) and maintains a web-site devoted to ham radio reference information for newcomers at http://www.No1PC.org.

Congratulations to WVARA – CA QSO Party

Dear WVARA Members,
Congratulations to WVARA for a competitive 3rd place finish among 32 clubs in the Small CA Club category.  Thank you for participating in the California QSO Party last October!

California QSO Party 2020 results are now available at:
https://cqp.org/Results.html

Highlights:
* 1,365 logs received.  48% increase in logs over 2019.  Beats all-time CQP record logs received by a margin of 360 logs.

* Records shattered.  104 new records set.  All-time CA S/O HP record set by KI6RRN and all-time CA S/O LP record set by N5ZO.  New club records set by SCCC, REDXA and TCG.

* Strongest Top 10 CA S/O scores in the history of CQP.  The threshold to place in the Top 10 of all Single-Ops inside CA was over 300,000 points, an all-time high.

* SEQUOIA 1×1 station success.  Over 42,000 QSOs were made by our 21 1×1 SEQUOIA stations.  11 stations outside of CA made more than 100 overall QSOs with the SEQUOIA stations.  Over 500 stations spelled SEQUOIA at least once.

* 57 plaques, 40 bottles of wine, 13 SEQUOIA calendars and hundreds of certificates will be awarded.

* Largest results package in CQP history.  19 PDF files, links to two SEQUOIA station blogs, and a link to your 2020 CQP Certificate of Achievement await you at https://cqp.org/Results.html
Stand by for more information about the SEQUOIA certificates.

* Make sure to look for your callsign listed in all of these files.  You may very well find yourself listed in a Top 10 table of the comeback award, operating time improvement award or the top 10 SEQUOIA QSO counts by operating class.

Thank you for participating in CQP 2020!

February Membership Meeting

WVARA’s next monthly meeting will be on Wednesday, February 10, at 7pm via Zoom.  

Gary Johnson, NA6O, will tell us how to reduce/eliminate RF noise before it gets into your transceiver.  Gary will discuss how RF interference to amateur radio is steadily increasing due to the wide-spread use of poorly-filtered commercial electronic devices. In this talk, we will learn about these noise sources, how to locate them, and a number of techniques to reduce their effects. Lists of references and resources will be provided.

Bio:    Gary Johnson, NA6O, is a retired electronics engineer with a degree from the University of Illinois. His entire career was spent at Lawrence Livermore National Laboratory where he used his diverse skills in measurement and control systems, electro-optics, transducers, circuit design, and technical writing. Gary holds nine patents and wrote two books. He grew up near Chicago and was first licensed as a junior high student in 1972. These days, he enjoys station building, contesting, and anything to do with CW, in addition to his other hobbies of woodworking and metalworking. He and his wife, Katharine, live in Livermore.

Zoom meeting information will be sent via email.

Hope to see you there!Jim, K6EI, WVARA Vice President
