his other successes. It brought him early employment, while a teenager, as a radio broadcast engineer. The hands on experience of amateur radio was the foundation upon which stood his later successes.
A Fullbright Scholarship brought Yehuda to Israel where he studied at the Weizman Institute of Science, in 1966, and where he did research on the use of electrical signals on the inner ear to stimulate auditory response, using guinea pigs. Yehuda went on to receive a doctorate and was invited to establish the Electronics Department at the Jerusalem College of Technology, in Jerusalem. Yehuda taught courses in microprocessors, in the 1970s, where he applied his hands on experience to combined both hardware and software that gave his students a competitive edge in the marketplace.
Yehuda went on to establish two companies, one in medical technology, and the other around using high voltage transmission lines for the conduction of communication signals using ferrite couplers.
Yehuda is active in the Jerusalem Amateur Radio Society and helps 4Z1UG maintain the two meter repeater that serves the Jerusalem area. He has since returned to the Jerusalem College of Technology, after 40 years, where he teaches a course in radio electronics that has led to over 15 students to pass the entry level amateur radio license test in Israel.
Yehuda lives in Efrat, Israel, a city in the Judean Hills South of Jerusalem, with his wife and lots of grandchildren.
