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.

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.

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.

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.”
