In 1948, R/9 magazine published an article by Robert Moore, W6DEI, titled “Single Sideband Transmission for Amateur Radiophones.” This article was pivotal in introducing and promoting single sideband (SSB) modulation to the amateur radio community. SSB, a more efficient form of amplitude modulation (AM), offered significant advantages, including better bandwidth utilization and improved signal clarity. Moore’s article helped amateur radio operators understand and adopt this advanced modulation technique, which became a standard in amateur radio communications. The widespread use of SSB has greatly enhanced the efficiency and quality of amateur radio transmissions, showcasing the importance of technological innovation within the hobby.
