Hi Peter,
I am wondering if these remarks about The K2 SSB are old. The following is
how I remember the discussions on this subject and I think some of the text
is on the K2 website. I am surprised no one has said the following before.
And this is all from my memory, which is probably failing so if others can
correct me, that’s OK:
The K2 was originally a CW rig with capability for upgrade. When the SSB
module was first introduced, I did hear comments about the K2 being better
at CW than SSB. Not sure why. But I remember reading about how the K2
group was later getting feedback from some hams who were SSB connoisseurs
who criticized the shape of the original filters response. As I recall it
was OK but could be better. Then the K2 team researched this and, with the
newer sorting tolerances in cheap filter manufacturing, realized that the
SSB response could be widened and not suffer from excessive ripple. I
believe another mod was made to alter the SSB response shape at another
location in the K2, and also the overall shape of the filter's response was
considerably modified. I have seen before and after pictures of the
filter's response. The results were that the K2 SSB performance, sound
wise, is now excellent. I made these mods to my K2 #402. Again I think
most of this I read on the web and probably most of it on the Elecraft web
site. Perhaps its time for Eric or Wayne to chime in.
I know of a lady on the list that uses a K2 on SSB for nets. She is the
only woman I know that does not sound whiney on SSB. I attribute this to
the rig she is using.
In short the K2 is now simply one of the best.
Steve, W2MY
