Alan Johnston, KU2Y, has a continued interest in amateur satellites since his early beginnings in ham radio over 40 years ago.  Now the AMSAT’s VP of Educational Relations, Alan reaches out to educate the general public about intriguing world  amateur satellites, and satellite technology using Cubesatsim, a live classroom simulation of satellite communications. Furthermore, he turns to high-altitude balloon launches as a practical, hands-on approach to bringing amateur payloads closer to space, thereby affording opportunities for tangible experience and simulation.KU2Y is my QSO Today.
