So let me get this straight... In DSB-SC... both sidebands are
transmitted... but there is no carrier sent at all? Correct?... and the
carrier is re-inserted at the receiver.

100% correct.


Now with the swing set-up... both sidebands are transmitted... along
with the carrier... but the carrier's amplitude changes from extremely
low to a normal AM carrier when the modulation is added.

right again.
