The ARRL
“It tells of the interesting events in the maritime port of San Francisco at the turn of the 20th century, as early radio was being developed, and follows the hams who designed new devices and equipment to address steamship traffic plying the Pacific Ocean,” Wesling said. “Their efforts to break the east coast monopoly on tubes and to extend radio into the microwaves as the country approached World War II form the basis for what became Silicon Valley.”
Wesling said the presentation traces early vacuum tube development and other contributions by Bay Area amateurs, “and the continuing spirit of hobbyists and collaborators that fuel today’s high-tech mecca.” The presentation runs about 1 hour.
A graduate of Stanford University, Wesling, a IEEE/CPMT Society Distinguished Lecturer, retired from Hewlett Packard in 2001, and then served for 10 years as Communications Director for the IEEE’s San Francisco Bay Area Council.
