§  80.205   Bandwidths.

   (a) An emission designator shows the necessary bandwidth for each class
   of emission of a station except that in ship earth stations it shows
   the occupied or necessary bandwidth, whichever is greater. The
   following table gives the class of emission and corresponding emission
   designator and authorized bandwidth:

   direction finding.

   ^3Applicable only to EPIRB's.

   ^4Radioprinter transmissions for communications with private coast
   stations.

   ^5NB-DP radiotelegraph and data transmissions for communications with
   public coast stations.

   ^6Applicable only to radioprinter and data in the 156–162 MHz band and
   radioprinter in the 216–220 MHz band.

   ^7Applicable only to facsimile in the 156–162 MHz and 216–220 MHz
   bands.

   paragraph (b) of this section.

   ^9Applicable only to marine hand-held radar.

   ^10Applicable only to on-board frequencies for maneuvering or
   navigation.

   ^11Transmitters 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.

   ^12Applicable to radiolocation and associated telecommand ship stations
   operating on 154.585 MHz, 159.480 MHz, 160.725 MHz. 160.785 MHz,
   454.000 MHz, and 459.000 MHz; emergency position indicating
   radiobeacons operating in the 406.000–406.1000 MHz frequency bank; and
   data transmissions in the 156–162 MHz band.

   ^13Class C EPIRB stations may not be used after February 1, 1999.

   ^14The information is contained in multiple very low level subcarriers.

   (b) For land stations the maximum authorized frequency deviation for
   F3E or G3E emission is as follows:

   (1) 5 kHz in the 72.0–73.0 MHz, 75.4–76.0 MHz and 156–162 MHz bands;

   (2) 15 kHz for stations which were authorized for operation before
   December 1, 1961, in the 73.0–74.6 MHz band.
