I found an obscure reference which reads as follows. There is no
further information given.
"One person with whom I discussed this said you can use a lower
frequency carrier than the modulation. You can view the resulting
signal via a 'constellation diagram' such as used in quadrature
amplitude modulation and other techniques associated with modems, FSK
and PSk radio."
Is this bunk, or would someone care to venture how this might be
achieved?
I don't think they are referring to something as simple as
superimposing a HF ripple on the LF. It seems to equate to full AM of
lower frequency by a higher one, instead of the normal way around.
Awaiting your invocations.
