  § 97.309   RTTY and data emission codes.

   (a) Where authorized by § § 97.305(c) and 97.307(f) of the part, an amateur
   station may transmit a RTTY or data emission using the following specified
   digital codes:

   (1) The 5-unit, start-stop, International Telegraph Alphabet No. 2, code
   defined  in  ITU-T  Recommendation  F.1, Division C (commonly known as
   “Baudot”).

   (2) The 7-unit code specified in ITU-R Recommendations M.476-5 and M.625-3
   (commonly known as “AMTOR”).

   (3)  The  7-unit,  International Alphabet No. 5, code defined in IT--T
   Recommendation T.50 (commonly known as “ASCII”).

   (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.

   (b) Where authorized by § § 97.305(c) and 97.307(f), a station may transmit a
   RTTY or data emission using an unspecified digital code, except to a station
   in  a  country with which the United States does not have an agreement
   permitting the code to be used. RTTY and data emissions using unspecified
   digital codes must not be transmitted for the purpose of obscuring the
   meaning of any communication. When deemed necessary by a Regional Director
   to assure compliance with the FCC Rules, a station must:

   (1) Cease the transmission using the unspecified digital code;

   (2) Restrict transmissions of any digital code to the extent instructed;

   (3) Maintain a record, convertible to the original information, of all
   digital communications transmitted.
