Page 3 of 4 Emission Designators - First Symbol Types of Modulation of the Main Carrier: Description Symbol Emission of an unmodulated carrier N Emission in which the main carrier is amplitude-modulated (including cases where sub-carriers are angle-modulated): Double-sideband A Single-sideband, full carrier H Single-sideband, reduced or variable level carrier R Single-sideband, suppressed carrier J Independent sidebands B Vestigial sideband C Emission in which the main carrier is angle-modulated: Frequency modulation F Phase modulation G Emission in which the main carrier is amplitude and angle-modulated either simultaneously or in a pre-established sequence D Emission of pulses:* Sequence of unmodulated pulses P A sequence of pulses: Modulated in amplitude K Modulated in width/duration L Modulated in position/phase M In which the carrier is angle-modulated during the period of the pulse Q Which is a combination of the foregoing or is produced by other means V Cases not covered above, in which an emission consists of the main carrier modulated, either simultaneously or in pre-established sequence, in a combination of two or more of the following modes: amplitude, angle, pulse W Cases not otherwise covered X Whenever frequency modulation "F" is indicated, Phase modulation "G" is also acceptable. * Emissions where the main carrier is directly modulated by a signal which has been coded into quantized form (e.g. pulse code modulation) should be designated under amplitude modulation or angle modulation. 4/23/2007

Page 4 of 4 Emission Designators - Second Symbol Nature of Signal(s) Modulating the Main Carrier: Description Symbol No modulating signal 0 A single channel containing quantized or digital information without the use of a modulating sub- 1 carrier, excluding time-division multiplex A single channel containing quantized or digital information with the use of a modulating sub- 2 carrier, excluding time-division multiplex A single channel containing analog information 3 Two or more channels containing quantized or digital information 7 Two or more channels containing analog information 8 Composite system with one or more channels containing quantized or digital information, together 9 with one or more channels containing analog information Cases not otherwise covered X Emission Designators - Third Symbol Type of Information to be Transmitted: Description Symbol No information transmitted N Telegraphy - for aural reception A Telegraphy - for automatic reception B Facsimile C Data transmission, telemetry, telecommand D Telephony (including sound broadcasting) E Television (video) F Combination of the above W Cases not otherwise covered X 4/23/2007
