The one advantage of AM is that it may be easier to build a low power AM
transmitter than an SSB transmitter, though now that everyone wants a
VFO, it may not.

Sorry, don't follow that logic!
On the other hand, that's when DSB with a suppressed carrier stepped in.

Actually, most of those who TX DSBSC do NOT have the appropriate
means of receiving it, for, unless you cheat by chopping off one of the
sidebands
(not to be confused with sidetone, STC) you need a injection oscillator
tightly phase locked to the original carrier, for a 90 degrees phase error
will result
in a received signal strength of zero!



Oops, phrased that badly, for it has nowt to do with the received signal
strength, but
the demodulated audio will disappear.
