David Larsen

David Larsen KK4WW became interested in electronics as a boy and was licensed as an Amateur Radio Operator in 1953. After graduating from high school in 1957, he served in Uncle Sam’s Navy for 2 years as an electronic technician, and went to Oregon State University for a degree in Business and Technology (Electronics). He spent some years in the electronic industry as an engineer, and the next 31 as a university teacher in electronic instrumentation at Virginia Tech in Blacksburg, VA (retired 1998). For ten years at VT, David assisted the Office of International Development and received the Faculty Service Award in 1995 for “outstanding service in the outreach mission”. For many of those years, he was associated with land and farming with the start-up of a Christmas tree farm and marketing organization, which developed into a serious operation with hundreds of acres of Christmas trees and was a good sale for Larsen in 1993.

All hobbies, products, reoccurring events and topics of great interest generate magazines or newsletters. Now with the world wide web the shift is to forums and blogs online. During the late 70’s and 80’s dozens of computer magazines were published, however most had a very short life – just like most of the early microcomputers. First was the simple newsletters and a few of them became successful magazine publications. Most likely the first real microcomputer magazine was “Byte” and interestingly it lasted through all the publishing wars and is still a popular computer magazine.


The Foundation for Amateur International Radio Service was created as an idea during a train trip from Moscow to the Western Ukraine. There were five Americans visiting Ukrainian and Russian friends. The visit was set up to distribute donated equipment in Russia and Ukraine. It seemed that a formal group was needed to do this type of volunteer work in an organized way on a regular basis...


I'd like to give one example of how the Internet has been so useful in enhancing radio amateur communications. We have a regular radio schedule on 20 meters three times per week, our normal mode of operation is single sideband (SSB). We use the net to keep in contact with members and friends of the Foundation for Amateur International Radio Service (FAIRS). Our (FAIRS) headquarters is located in Floyd, Virginia and the net includes Canada, USA, Caribbean, South America and Ukraine.
