Amateur Radio Operator for Six Decades +4years KK4WW David Larsen

It seems almost a mystery to me how I became an amateur radio operator (ham radio operator). My parents were old-fashioned farm folks, both born before the turn of the century (in the 1800s).  They had no knowledge of electronics or radio, so I was on my own. I had always liked mechanical gadgets and began reading the magazine Mechanics Illustrated at about age 12. The magazine had interesting articles about how you could receive radio signals with a simple device that required no power. Just a tuning coil, crystal detector, earphones and a wire antenna. I managed to get the parts and build one and it worked like magic!
My interest in how radio worked took off and it has been a lifelong interest and career. I received my first amateur radio license in 1954 and took electronics classes throughout high school. I was an electronic technician in the Navy and several jobs after college including Raytheon, Fairchild Semiconductor, and Varian Associates. I then taught Electronic Instrumentation and Automation as a faculty member at Virginia Tech in Blacksburg, VA for 31 years before retiring in 1998. I was active as a radio ham all those years and am still active here in Floyd, Virginia on a regular basis.

See current operation of David KK4WW at N4USA and as J79USA Dominica.

       David gives introduction to his Six Decades + as Amateur Radio Operator.

A Few Highlights
-Major DX Operation to Bangladesh in 1993 as Team member.  Made 25,000 radio contacts
-Casual DX operation in Russia, Poland, Ukraine, Lithuania, China, Guyana, Dominica, Trinidad, Grenada, and Puerto Rico
-During the past 45 years I have developed one of the largest and most significant personal historical    microcomputer collections in the world. In March 2017 I moved the Bugbook Computer Collection to the "Computer Museum of America" in Roswell, Georgia. In September 2017 I sold one of my remaining rare Apple-1 computers at auction.
-During the 70s and early 80s I was part of a team that created over seventy books on the subject of computers and electronics-starting as Bugbooks and becoming the “Blacksburg Continuing Education Series”

In the early days (50s/60s) I enjoyed building ham equipment. My first kit was a Heathkit AT-1 Transmitter (25 Watts CW). In 1964 I built from scratch a 1 KW SSB mobile linier Amplifier using UA572 tubes; great signal. I still have this rig today.
