Rex was first licensed in May 1966 as Novice WN7FKT, a young teenager in Utah. Then the Novice was good for one year, non-renewable, and only one per lifetime. Upon upgrade to General the call became WA7FKT. Soon the upgrade was made to Advanced. The Extra ticket had to wait as at the time there was a mandatory requirement to hold a General or Advanced for four years before the Extra test could even be taken! The Extra was obtained in 1978 upon passing the 20 WPM code and theory tests, which, at the time, were taken before an official FCC field engineer. Another old call was WB0VFM used in Lincoln, Nebraska from 1975 to 1978. The present call, K0KP, was assigned in 1978.
Rex was elected ARRL Section Communications Manager (SCM) for the Nebraska Section, and served at this post until moving to Minnesota in 1980. Rex also served as an ARRL Official Observer (OO) and Assistant Director of the Midwest Division. Interests include high speed CW on HF, SSB and CW on 6 meters, QRP, beacons, and building gear. Rex is a Life Member of the ARRL, a member of the FISTS CW Club, The Six Club, SMIRK, QRP-ARCI, and the MN QRP Society. Rex holds an FCC lifetime Extra Class Operator License, number AE-17-811, issued in Kansas City, MO and signed by Field Bureau Chief Engineer James Crowell, Issuing Officer, and countersigned by William Tricarico, Secretary of the FCC.
Rex is married to Karen, KA0DMH, who holds a Tech Plus ticket.
