[Amps] S/S Amp's

[Fuqua, Bill L]

  Synchronous detection requires either a carrier, can be reduced in amplitude,  to lock on or a somewhat complex
quadrature phase detection system to lock the BFO by maintaining an in-phase
relationship between the upper sideband and lower sideband.

Why are Hams still rf-spamming 160 & 80m with AM carriers
when a DSB suppressed-carrier signal is just as good, uses
less power, and may be sync-detected to remove flutter, etc?

I know, I know, ... never mind ... sigh.
