Troubleshooting Electronic Circuits at WVARA’s Feb 12 meeting

The next WVARA meeting will be 7pm on Wednesday, February 12.  This will be at our usual meeting place: the Red Cross Building on 2731 N. First Street (Meeting Room #5) in San Jose.  Entry is via the side door on the west side of the building — look for the red WVARA sign.   Visitors are welcome, and of course there will be chocolate chip cookies.  If you haven’t been to the Red Cross, “talk-in” is usually available on the Association’s repeaters. Best choice would be 2m/220.  

At this month’s meeting Ron Quan, KI6AZB, will give a presentation based on his latest book, “Troubleshooting Electronic Circuits: A Guide to Learning Analog Electronics”.  Ron’s presentation will cover selected topics from the book, including electronic components, LEDs, and ham radio circuits such as oscillators, Software Defined Radio mixers and audio amplifiers.  Ron will discuss how to debug circuit problems and fix via re-design.

Ron built his first crystal radio in the mid 1960s. Since then he has repaired radios, Hi Fi stereos, TVs, oscilloscopes, signal generators, lab power supplies, and broadcast equipment.  Before passing his Extra Class License, he was a broadcast engineer in the 1970s for radio stations KALX FM and KNEW AM. He received his engineering degree that led to working at Ampex, Sony, and finally Macrovision where he was a Principal Engineer.  Ron has written three electronics books and has taught at the university level on analog RF communications systems, signals, and circuits.

 Looking forward to seeing you at next Wednesday’s meeting!  BTW, several of us meet for dinner near the Red Cross around 5:45pm prior to the meeting at Disn-N-Dash (2551 N. 1st St. San Jose):  https://dishdash.com/  Feel free to drop by and join us for dinner!    WVARA members also dine at Panera Bread at Coleman Avenue at Autumn Parkway, at the San Jose Market Center at 6 p.m.

October 9, Meeting

Join us to hear about Clay’s suitcase DX expedition and communications support for International Health Services (IHS) work in Honduras. IHS Found in 1982, International Health Service is an all-volunteer 501(c)(3) medical organization that provides medical and dental care to the impoverished people of Honduras. Each February approximately 100 people from all over the world head out on teams to various regions of Honduras and spend two weeks helping the people of Honduras and Nicaragua. IHS uses Pactor III & amateur radio as the main communication link for the field medical teams as they are often working in locations that are outreach of phone / cell service. Ham radio is used to arrange transportation, housing and schedule surgery or other medical service that the field team is not able to provide.

The DX expedition was in West Palm Beach on Roatan Inland for two days before moving to Rus Rus near the Nicaragua boarder for 8 days. Rus Rus DX expedition was done jointly with IHS field work as time & power allow.

Clay Couger was licensed in 92 as N5YJZ and was active in amateur radio throughout the 90’s while in college at Oklahoma State Univ. He severed one term as president of W5YJ OSU amateur radio club. Clay officially joined the Okie club by moving to California in 1999 and fell away from the hobby as he got caught in the Silicon Valley rat race. He became active again in 2016 due to a renewed interest in disaster support (wife says he needed a new reason to shop). He prefers to build things then get on air but has found FT8/FT4 to be wonderful mode as it can be run in the background while doing other things at the workbench.

International Health Services is actively recrewing for the Feb 2020 mission on February 14 to February 28. IHS are looking for licensed medical (DDS, DDO, MD, RN, OD, Dental Ass’t, NP, LPN, RDH, PA, CRNA, RPh, Pharmacist, Paramedic and EMT) professionals, amateur radio operators (general Lic and above), translators (Spanish, Garifuna, Miskito, Sumo, Pech, and Jicaque). We engorge spouses to join as there is always a need for next extra hands need to support the teams. For more information on IHS see their website at http://www.ihsmn.org/.

Thank you Logan Zintsmaster (KZ6O)

Many thanks to this month’s guest speaker, Logan Zintsmaster (KZ6O), from Santa Clara County ARES/RACES! Logan led us through a discussion of “ARES – RACES – ACS – Emergency Communications in Santa Clara County”, a wonderful overview of how emergency communications are organized in Santa Clara County and how to get involved.
