  § 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.
