Hi,

CQ magazine, May '65 page 75, gave a simple method
of transmitting a.m. with a KWM-2.

And Swan 350's had the carrier balance (null) pot right on the front
panel, and they claimed that allowed you 125W dc input AM on all bands.

Unfortunately, the carrier is injected before the SSB filter, and since the
filter's rejection skirt is positioned well over the top of the carrier(better
SSB carrier rejection, you see), you lose most of your carrier power before
you even start.

There was a certain amount of interest in running early SSB rigs in AM
mode, but fortunately that faded rapidly.
