The "modern" SS rigs do NOT generate AM in that manner.
The last radio that I saw that used a carrier with ONE sideband for AM
was the Collins KWS-1. That is precisely why I did NOT procure one when
the opportunity arose.
As to Vestigal SB, that INDEED is used in Amateur TV signals, however, I
cannot remember whether it is for slow scan or fast scan. It eludes me
at the moment, AND no carrier is used.
