Bonnie,
You need to revise your list somewhat, and everyone should know these
are not necessarily "official". The ITU (more specifically Working
Party 8A) shows Pactor II as 375HJ2D and Pactor III as 2K20J2D. I
would assume these are as official as it gets.
In order for an emission to be classed as "G" it must be an
Emission in which the main carrier is angle-modulated:
Phase Modulation G
There is no "main carrier" in a SSB transmitter because by definition
it is suppressed.
It seems most folks look at the following definition as the correct one.
Emission in which the main carrier is amplitude-modulated
(including cases where sub-carriers are angle-modulated):
Single-sideband, suppressed carrier J
You'll notice this says specifically - "including cases where
sub-carriers are angle-modulated".
Also MFSK16 is defined by the ITU as either 316HJ2D or 316HJ2B,
presumably based upon data or keyboarding.
These are all from a letter that the NTIA has on its web site.
