I earned my ticket in 1998 in college at Iowa State University working on an amateur hydrogen-line radio telescope along with KC0AYD. I was off the air for almost 20 years after college until 2017, when I got interested in APRS, SDR, and then got bit by the amateur radio satellite bug.


  • Low Earth Orbit Satellites
    • FM Satellites
    • Packet Satellites (APRS satellites like ISS and FalconSat-3 Packet BBS)
    • SSB Linear Satellites (Oscar-7 and other active linear satellites.)
  • Summits on the Air (SOTA)

Please see for a full, updated bio.
