Let's join Bob Rydzewski of California Historical Radio Society to learn about the earliest days of ham radio as he tells the inspiring story of Fred Mudgett, the first amateur to aid in disaster communications, and the ultimately tragic tale of Henry Heim Jr., presented to the U.S. Congress as a national security risk. Amateurs like these helped pave the way to wireless communication as we know it today. The talk even features our very own Rachel Lee! Enjoy!

The earliest days of ham radio were marked by crude spark equipment...
