Allen, KB8MTZ

My name is Allen. I live in Cleveland, Ohio. My hobbies are electronics, computers, amateur radio, tracking satellites and spending time with my family. My ham radio call is KB8MTZ. I enjoy fixing, operating and restoring old tube radio equipment. I also like building AM high power transmitters.

I work at NASA's Glenn Research Center in Cleveland Ohio. I work with the ATS-3 Communications Satellite. The satellite was launched from NASA's Cape Kennedy on November 5th, 1967 on top of an Atlas-Agena D launch vehicle. The satellite carried with it nine major experiments. Key experiments included the Multicolor Spin Scan Cloud Camera which provided the first full disk photos of Earth . It also provided the first satellite to aircraft communications over the Atlantic Ocean. In the summer of 1997, I traveled with Astronaut Chuck Brady and installed a satellite ground station at Tern Island Hawaii.
