Many of us entered the ham radio hobby from building a crystal set or using a short wave receiver growing up. Tom Witherspoon, K4SWL, established his credentials in short wave radio before joining the ham radio ranks. Active in QRP as well as short wave listening, Tom is the founder of Ears to our World, a non-profit organization that brings radio to rural and undeveloped parts of the World. K4SWL joins Eric, 4Z1UG, in this QSO Today.
