The use of spread spectrum communications began in the Amateur Radio Service in March 1981 when the FCC issued a Special Temporary Authority (STA) to AMRAD. W4RI and K2SZE made the premiere HF contact using frequency hopping. WA3ZXW, N4EZV, WB5MMB and K8MMO were also involved in these early experiments. A joint FCC-AMRAD 'fox hunt' demonstrated that spread spectrum stations could be located with direction-finding techniques. N4ICK became involved later, beginning in 1986.
At AMRAD's urging, in 1985 the FCC amended Part 97 of its Rules to permit regular spread spectrum communications in the Amateur Radio Service with certain restrictions as to spreading methods and limited to frequencies above 420 MHz. These restrictions have been the subject of controversy within the Amateur Radio community ever since, some desiring to remove them entirely including permitting spread spectrum operation on all amateur bands, others wishing to tighten them. STAs subsequently have been issued to K6KGS and a number of amateur stations on the West Coast, and in 1996 to the Tucson Amateur Packet Radio Corporation (TAPR), both of which allow operation above 50 MHz with unrestricted spreading codes. In 1996, the American Radio Relay League (ARRL) petitioned the FCC to permit other spreading sequences, require automatic power control when transmitting at powers above 1 watt, while keeping the lowest operating frequency at 420 MHz. The FCC has issued a Notice of Proposed Rule Making and is expected to decide on rule changes during 1997-98.
