(a) Authorization to use radiotelephone and radiotelegraph emissions by ship and coast stations includes the use of digital selective calling and selective calling techniques in accordance with §80.225.

(c) Authorization to use single sideband emission is limited to emitting a carrier; (1) For full carrier transmitters at a power level between 3 and 6 dB below peak envelope power; (2) For suppressed carrier transmitters at a power level at least 40 dB below peak envelope power; and (3) For reduced or variable level carrier: (i) In the 1600–4000 kHz band: (A) For coast station transmitters 18±2 dB below peak envelope power; (B) For ship station transmitters installed before January 2, 1982, 16±2 dB below peak envelope power; and (C) For ship station transmitters installed after January 1, 1982, 18±2 dB below peak envelope power. (ii) In the 4000–27500 kHz band: (A) For coast station transmitters 18±2 dB below peak envelope power; (B) For ship station transmitters installed before January 2, 1978, 16±2 dB below peak envelope power; and (C) For ship station transmitters installed after January 1, 1978, 18±2 dB below peak envelope power. (d) The authorized classes of emission are as follows: [51 FR 31213, Sept. 2, 1986; 51 FR 34984, Oct. 1, 1986; as amended at 52 FR 7418, Mar. 11, 1987; 52 FR 35244, Sept. 18, 1987; 53 FR 8905, Mar. 18, 1988; 53 FR 37308, Sept. 26, 1988; 54 FR 40058, Sept. 29, 1989; 54 FR 49993, Dec. 4, 1989; 56 FR 11516, Mar. 19, 1991; 57 FR 43407, Sept. 21, 1992; 58 FR 33344, June 17, 1993; 62 FR 40305, July 28, 1997; 63 FR 36606, July 7, 1998; 67 FR 48564, July 25, 2002; 68 FR 46963, Aug. 7, 2003; 69 FR 64672, Nov. 8, 2004]

See §§ 80.371(c), 80.373(f) and 80.385(b). Transmitters approved before January 1, 1994, for G3E emissions will be authorized indefinitely for F2C, F3C, F1D and F2D emissions. Transmitters approved on or after January 1, 1994, will be authorized for F2C, F3C, F1D or F2D emissions only if they are approved specifically for each emission designator.\3\ Frequencies used in the Automated Maritime Telecommunications System (AMTS). See § 80.385(b).\4\ Types of emission are determined by the INMARSAT Organization.\5\ Transmitters approved prior to December 31, 1969, for emission H3E, J3E, and R3E and an authorized bandwidth of 3.5 kHz may continue to be operated. These transmitters will not be authorized in new installations.\6\ G3D emission must be used only by one-board stations for maneuvering or navigation.\7\ Frequencies used for cable repair operations.
