SB QST @ ARL $ARLB094 ARLB094 Digital rules clarified ZCZC AG61 QST de W1AW ARRL Bulletin 94 ARLB094 From ARRL Headquarters Newington CT October 12, 1995 To all radio amateurs SB QST ARL ARLB094 ARLB094 Digital rules clarified The FCC, responding to a request from the ARRL, has clarified its rules regarding Amateur Radio stations' use of digital codes. The ARRL, in a letter to the Commission, said that some amateurs had expressed concern about the propriety of using the CLOVER, G-TOR, and PacTOR codes on the HF bands (below 30 MHz), because FCC rule 97.309(a) ''appears to authorize'' only Baudot, AMTOR, and ASCII codes. The League told the Commission that it had worked with the developers of CLOVER, G-TOR, and PacTOR to document the technical characteristics of those codes, and asked the FCC to remove any doubt about their legality on the HF bands. The FCC agreed, saying that the use of the three modes does not conflict with its objective of preventing the use of codes or ciphers intended to obscure the meaning of the communication. As a result, the FCC added a paragraph (4) to Part 97.309(a) to read: (4) An amateur station transmitting a RTTY or data emission using a digital code specified in this paragraph may use any technique whose technical characteristics have been documented publicly, such as CLOVER, G-TOR, or PacTOR, for the purpose of facilitating communications.
