RE: What makes K2's SSB performance less impressive than onCW ?

Peter,

The K2 generates a very good and clean SSB signal.  One point that may be
considered 'weak' is the need to use a microphone with the higher output
levels (the Heil HC4 and HC5 elements are low output and may need a
pre-amp).  The other 'weakness' of the K2 SSB is the absense of anti-vox.
IF you mainly use PTT for SSB operation (as I do) then the K2 will serve you
well on SSB, but if VOX is a major requirement, you may find some weakness
there.  There is a mod out there in cyberspace which adds anti-VOX and
improves the VOX on the K2 - if you are interested look for Stewart Baker's
information.

As with CW, the K2 BFO settings for SSB FL1 will make a good or a poor
signal on the air, but that is easily rectified with a session with
Spectrogram.  I am certain there are a number of K2s out there with poorly
aligned SSB FL1 filters, and that alone could generate some negative
opinions about the K2 on SSB.
