Dave started in Amateur Radio at a very young age and learned electronics "hands-on" style. He enjoyed all areas of amateur radio today--especially CW, QRP, DXing and satellites. Dave worked in radio, TV and microwave engineering, and designed several unique circuits and mini rigs. He taught college electronics and held 3 degrees in Applied Electronic Technology plus an Amateur EXTRA class license and Radar Endorsed FCC First Phone/GROL license. Also he was a pioneer in SSTV and assisted several world areas in becoming operational in video communications. As of 2010, he had written over 1,000 articles/columns and 29 books on all aspects of amateur radio as well as writing 3 columns in CQ Magazine plus articles for RadCom of the UK, 100 Watts of Thailand, SARL of South Africa and other international ham magazines. His most recent book (The World of Keys) featured CW instruments like few people have ever seen. In addition to amateur radio, Dave was researching Quantum Physics and Radio Astronomy, and developing several definitive theories on electronic time travel based on matter transducers, light speed accelerators and Einstein's theory of relativity.
