Payload specialist Martin J. Fettman listens to an amateur radio instruction by crew trainer John J. Maca. Members of the STS-58 crew were training with amateur radio equipment at the Johnson Space Center (JSC). The STS-58 flight will carry the Shuttle Amateur Radio Experiment (SAREX) payload, configuration C, which includes FM voice and packet. Three of the seven crew members are licensed amateur radio operators. Fettman's call letters are KC5AXA; William S. McArthur, mission specialist, KC5ACR; and Richard A. Searfoss, pilot, KC5CKM. Licensed students at a number of schools around the country will have the opportunity to talk directly with the astronauts during the 14-day flight.
