The big advantage to DSB is that you can use a Costas Loop detector to
regeneraate the carrier for automatic synchronization - no BFO drift,
no duck talk. This was a big advantage with the drifty radios that were
common before the 1950's. SSB wasn't very satisfactory until Art
Collins proved that a sufficiently stable receiver could be built.
