  Mark,

Actually, an SSB signal modulated by a single tone sine wave IS a CW 
transmission.  There have been SSB transmitters commercially built which 
did exactly that for CW - but that was in times past.

If the supressed carrier is sufficiently below the RF amplitude of the 
transmitted tone to meet the FCC requirements for spurs, then it is 
perfectly legal.

Don't try that with an AM signal - that becomes MCW which is illegal for 
HF amateur bands.
