During high school he was employed with the Missouri Highway Patrol Dispatch Center where he was one of the last Morse Code operators. Known throughout the world by the call sign of N0SS, Tom was a federally-licensed Amateur Radio operator holding the highest license grade of Extra Class. His specialty was the International Morse Code which he employed on a daily and nightly basis at a proficiency level in excess of 50 words per minute. During the 53 years of his ham radio career, he personally conducted numerous licensing classes which resulted in hundreds of individuals of all ages obtaining their Amateur Radio licenses. Experienced ham operators with technical expertise frequently sought out Tom Hammond's advice for resolution of complex electronic problems. He was a life member/50-year member of the American Radio Relay League and a member by invitation of the First Class Operators Club (FOC). He was a member of the Kansas City DX Club; International DX Foundation; CW Operators Club; Amateur Radio Emergency Services, and for many years was coordinator of the local Certified Volunteer Examiner program. He was also an avid contester who received numerous awards in various competitive categories. A past president and current Trustee of the Mid-MO Amateur Radio Club, Tom was instrumental in keeping the club alive during a period of transition during the 1970s. Beginning with the company's founding in 1998, he served as a designer, trouble-shooter, and Beta-Tester for Elecraft, Inc., of Aptos, California, a manufacturer of high-quality amateur radio equipment. Tom was a 50-year blood donor for the American Red Cross, and was Reunion Coordinator for Jefferson City High School Class of 1962 which has continuously met on a monthly basis since their 25th class reunion in 1987.
