[Elecraft] Is the K3 capable of ESSB?

[Fred (FL)]

The SSB bandwidth 2007 realities, sound familiar.
In 1978 - max bandwith over telephonic modems,
and conditioned AT&T lines was like 6250 baud.
A "limit" everyone agreed.

Then some clever soul or group, came up with
quadrature modulation - and rather quietly,
modems into the hot-copper telephone lines
of 52kbaud became a reality.

Similiarly, perhaps HF comms SSB, needs to
rethink its SSB modulation approach, to allow wider
more naturally sounding voice comms, and still
not take up unnecessary bandwidth, beyone which
supposedly 2.7khz now consumes. (when do we
start talking about amplifiers?)

This topic, started as an attempt to learn
technically what ESSB was all about, in
its application to Amateur Radio.  Never
learned anything, except everyone is
against it.

PLEASE close this topic, and wait out our
K3 purchase.  I have no interest in bandwidth
debates or reasons, rather just what they
have been working on in SSB techniques.  I'm
sure the FCC, and ARRL will reign us in, if
we stray.
