            Balloon-lifted Full Wave Loop Antennas

            Jim Deloach, WU0I

            NO meeting at Covington this month, due to the surge in COVID-19 cases. This was an on-line only meeting via Zoom.

            Are you stuck in your suburban lot with little or no space to put up an antenna, or are you stuck in a forest? For once, do you want to have the big signal, the kind you can only get from a really big antenna? Then what you need is a balloon-lifted antenna for your next Field Day or other contest event! This presentation shows you:

            • how to build a balloon-lifted full wave loop antenna,
            • explains why loops work so well with balloons,
            • discusses the unique operational details of flying balloon-lifted antennas,
            • shares examples of performance,
            • and cover regulations & safety procedures.
            Jim DeLoach, WU0I, is a Silicon Valley location technology and wireless systems engineer specialized in data analytics, field testing, tools development, and product definition.

            For fun, Jim loves to build high-performance temporary contest antennas and stations, but prefers to get out of the way and let the real operators take over as soon as the station is up and running.

            Jim is a frequent QST author, and winner of the Bill Orr Award for technical writing. His articles on balloon-lifted antennas appeared in QST, July 2007 and January 2009.

            There was no raffle, or WYWH prize for this meeting.

            Amateur Radio Resources that Save Space

            Steve Stearns, K6OIK

            NO meeting at Covington this month, due to the surge in COVID-19 cases. This was an on-line only meeting via Zoom.

            If you buy too much ham stuff, your house will overflow with Amateur Radio equipment. In this updated reprise of a popular talk, Steve, K6OIK shows how to continue collecting ham stuff even if your house is overflowing. The secret is to collect stuff that occupies no space. Radio information, in the form of articles, papers, books, or other publications, is available online. Whether it is an article from Popular Electronics, a home-study course from National Radio Institute, books on antennas, an NAB Engineering Handbook, papers from IEEE or the Bell System Technical Journal, it is available online if you know where and how to look. Steve shows the sources of information (software, archival articles, papers, and books) that Google often fails to find and yet is free and occupies no space except on your hard drive. This presentation is an update to the one given to FARS in July 2016.

            Steve's presentation is available on-line.

            HF phone: Golden Bear Amateur Radio Net, 3,975 kHz LSB at 1900 Pacific time daily.

            Steve Stearns, K6OIK, started in ham radio while in high school at the height of the Heathkit era. He holds an FCC Amateur Extra and a commercial General Radio Operator license with Radar endorsement. He previously held Novice, Technician, and 1st Class Radiotelephone licenses.

            He studied electrical engineering at California State University Fullerton, the University of Southern California, and Stanford, specializing in electromagnetic theory, communication, engineering and signal processing.

            Steve was Chief Technologist for TRW Firestorm Wireless Communication Products (now part of Northrop Grumman Electromagnetic Systems Laboratory), where he led the development of digital array signal processing technology for smart antennas, commercial wireless, and government communication systems.

            Steve served as assistant director of ARRL Pacific Division under Jim Maxwell W6CF, and is vice-president of the Foothills Amateur Radio Society. He holds ten U.S. patents and has over 50 professional publications. Steve has received numerous awards for professional and community volunteer activities.
            There was no raffle, or WYWH prize for this meeting.

            Quest for the Perfect Jelly Bean (Antenna Pattern)

            Andy Korsak, KR6DD

            This month’s meeting convened at Covington. COVID-19 Rules applied. This meeting was also available on-line via Zoom.

            Amateur Radio Direction Finding (ARDF) is often done with a single antenna that is mechanically rotated. This application imposes a special requirement on the antenna that is arguably more important than others, e.g. high gain, high directivity, or low SWR. The antenna pattern must be smooth.

            DFing can be done by peaking or nulling a signal. In either case the antenna lobe or null needs to be unique, known, stable, and independent of frequency. Side lobes and back lobes are undesired. Such lobes and the nulls between them vary with frequency in complicated and unpredictable ways. The ideal antenna pattern for ARDF resembles a jelly bean.

            Andy Korsak, KR6DD, describes his quest for the perfect jelly bean antenna pattern and progress to date. Andy will describe an antenna that almost achieves the jelly bean pattern. For antenna engineers, this talk suggests an interesting problem in pattern synthesis for a single antenna.

            Original call: VE3DVN - 1954 through about 1961. Came to U.C. Berkeley, CA Sept 1961 to study advanced mathematics. Graduated with a Ph.D. in 1966 and accepted a research position at Stanford Research Institute in Menlo Park CA

            Was relicensed in 1964 as VE3FZK on a return visit to Canada and operated under U.S. reciprocal annual permits until about 1977 when the FCC terminated that requirement. He was active on HF and ATV in the 60's and 70's. Now only on 2M, 220, 440 in the San Francisco Bay Area.

            Became a U.S. citizen in 1999 and FCC rules required obtaining a U.S. call sign.

            Current main amateur radio interests: VHF/UHF mobile rag chews, ARES, T-hunts (http://www.thunt.org), SSTV and other ham radio related software.

            As a result of many years of RDF activities assisting local OO's, accepted an invitation to join the Amateur Auxiliary to the FCC and then became the Official Observer Coordinator for the ARRL Santa Clara Valley Section of the Pacific Division. In 2019 the OO program was replaced by a new Volunteer Monitor MOU with the FCC -- did not join it. Now retired and engaged in a major project spear-heading implementation of an integrated monitoring network of participating amateur stations spread around the Greater San Francisco Bay Area.

            Potato-Powered QRPp Radio

            Dr. Hiroki Kato, AH6CY

            This month’s meeting convened at Covington. COVID-19 Rules applied. This meeting was also available on-line via Zoom.

            This talk recounts an experiment in using fruit and vegetable to power practical transceivers. It discusses how much electric energy various fruits and vegetables can generate and how to build QRPp radios. Hiroki's article on potato-powered radios appeared in QST, April 2022.

            Whether you are a ham, a kid looking for a science project, a CIA spy, or a prisoner in a Russian gulag, how to make simple batteries is a skill worth knowing.

            Hiroki Kato, AH6CY, was born in Hiroshima, and was first licensed as JA4AAO when he was in high school.

            After college, he came to the US to pursue graduate studies. Dr. Kato taught political science and linguistics at several universities, including the University of Hawaii, Harvard, and Northwestern.

            He got his current call sign when he lived in Honolulu.

            He later worked for early Silicon Valley startups, retiring in 2000.

            He enjoys QRP portable and QRO remote operations, having been on the air from many states and countries.

            When at home in California, he collects and restores boat anchor radios, focusing on World War II-era radios.

            Hiroki is a member of the ARRL. Hiroki previously spoke to FARS on British Spy Radios of WWII in October 2019 (QST, April 2016), and his coffee can antenna (QST, August 2021) won 2nd place in FARS 2019 Home Brew Contest.

            The Science of Audio

            Dr. Bob Heil, K9EID,
            founder of Heil Sound and Heil Ham Radio

            This month’s meeting convened at Covington. COVID-19 Rules applied. This meeting was also available on-line via Zoom.

            This meeting was one week earlier than usual. It was scheduled for the 3rd Friday instead of the usual 4th Friday of the month because of Field Day. Be sure to put the correct date on the calendar.

            Bob Heil, K9EID speaks on “the Science of Audio.” For added entertainment, he demonstrates the theatre organ from his new studio in Belleville, Il.

            Bob Heil’s sound career began early. By age 15, he was performing concerts as the house player on the Wurlitzer theater organ at the Fox Theater in St. Louis.

            He was also involved in ham radio and began tinkering with electronics and electronic design. In the early 1960s Bob opened “Ye Olde Music Shoppe” in Marissa, Illinois. The music store built a reputation among the professional bands who were touring because it carried stock of guitars and amplifiers that was unmatched at the time.

            In 1966, Bob founded Heil Sound with the goal to provide pro touring gear and systems. Heil Sound also provided system design and equipment for the emerging music festival scene. National accounts grew, and tours with Humble Pie, The Who, Grateful Dead, the James Gang and many others followed. Heil Sound had multiple sound crews on the road simultaneously.

            Bob developed pro sound innovations including the famed Talk Box for Joe Walsh and Peter Frampton, the quadrophonic mixer for the Who, and modular mixing consoles.

            In the early 1980s, the focus shifted to the amateur radio market. In the late 1990s, at the suggestion of Joe Walsh, a fellow ham radio enthusiast and friend, Bob set out to design a vocal microphone for live sound use. Heil Sound reentered the pro sound market and pro microphone manufacturing industry with the PR 20 microphone, and quickly earned a reputation for mic innovation. Heil mics featured large-diaphragm dynamic components that offered a high degree of sonic clarity and rear rejection. Subsequent microphone models, including the popular PR 40 and PR 30 followed. The PR 35 vocal mic was introduced and found favor with artists such as Stevie Wonder, Beck, Alice in Chains, Charlie Daniels, Joan Baez and others.

            In 2007 Heil Sound was honored with a permanent exhibit at the Rock & Roll Hall of Fame in Cleveland, Ohio. Heil mics are now mainstays in satellite radio broadcast stations, recording studios, and podcast and streaming rigs. In 2018, Heil Sound celebrated 50 years in business, or as they put it, “50 Years of Maximum Rock and Roll.”

            Second-Life LiFePO4 E-Bike Battery Pack Rebuild!

            Marcel Stieber, AI6MS

            This month’s meeting is scheduled to convene at Covington. COVID-19 Rules apply. This meeting is also available on-line via Zoom.

            Used battery packs are typically disposed of or recycled, but they are far from unusable. Second-life applications are a sustainable way to extend the usable service life of batteries in lower-performance applications. In this presentation, Marcel shows how to convert a used lithium iron phosphate (LFP or LiFePO4) e-bike battery into a 12V amateur radio friendly battery pack ready for a shack backup system, field day, or next SOTA outing!

            This presentation can be found at www.qrz.com/db/AI6MS.
