Time machine: K1JT's WSPR presentation

Ten years ago, almost a full solar cycle ago, I had the privilege of being with Joe Taylor, K1JT, at our Masscon event. Dr. Taylor gave an exciting talk about WSPR and, at that time, nobody had even thought about FT-8. You can hear his reasons and design decisions for turning a lab project into a real way of measuring and participating in this study of ham radio, propagation, and 'watching the sun'.
