Not true ... if 2K80J2D is permitted *any* J2D mode (including 45.45
baud AFSK) with a bandwidth *less than* 2800 Hz would also be permitted.
Traditional RTTY (170 H shift, 45.45 baud) can be equally
described as 370H0F1D, 370H0F1B, 370H0J2D or 370H0J2B depending on
whether it is generated as AFSK or FSK and whether the content is
generalized data or data meant for on screen display (automatic
detection).
