By using the Exalted AM method that goes back 70 years you dont need a fancy radio.

Modify the BFO for variable injection level and connect to the last IF thereby maintaining AGC. Its almost as good as a sync detector for selective fading and its easier to follow a slightly drifting carrier.

 Most hams today can't tune SSB clearly.
AM always sounds right. Perhaps we should have SSB reduced carrier rather than
suppressed carrier. Another point, DSB occupies same bandwidth as AM.
You could receive DSB or AM by detecting, using bfo and SSB filter, only one sideband but with the loss of 3dB signal to noise ratio compared to receiving it with synchronous detector.

For the same reason they spam other bands with ESSB, IM products,
keyclicks, splatter and/or full carrier AM - because they can and
the rules against stupidity, and bad operating practices either do
not exist or are not enforced.

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.

It's already in production.
