Episode 007 - Yehuda Cern - 4X1TQ
Growing up in Detroit, radio captured the imagination of six year old Yehuda, when his father, David Cern, set up a crystal set and strung a long wire antenna to the trees behind the house. This led to Yehuda to get his first ham ticket when he was only twelve, and a General Class license the following year. Yehuda was spared an early death from electrocution, when he was accidently shocked while working on the high voltage power supply of his home brew rig. Surviving electrocution and a bit more cautious, Yehuda went on to become an innovator in the area of medical and power electronics, and a teacher. Yehuda holds over 25 US patents, and numerous foreign patents. Amatuer Radio was the foundation on which Yehuda built ...
| 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.
