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

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.
