Covington Elementary | Los Altos, CA
Ed Fong, WB6IQN, will tell the story of the World’s first VHF frequency-synthesized handie talkie. The year was 1979. The radio was introduced as the Henry “Tempo S1.” However, it was really a rebranding of a design own by AOR Inc. AOR was a design house with offices in Tustin, CA, and in Tokyo, Japan. The radio’s synthesizer locked from 140-160 MHz, state-of-the-art at the time. Equally challenging was designing the circuit to work at less than 10 mA current draw. Ed will bring prototype serial # 0001 and demonstrate that it still works to original factory specifications. Ed will tell the interesting story of the Tempo S1 and his work on the innovative PLL for this radio.
Simulcast on Zoom.
