Fred,
Thanks for your comment. I have to assume you have a less then staller
opinion of the Juma PA-100-D. Well with -28 db third order IMD this
specification matches the K3-100's IMD spec. and this is with 100 watts
out. All the reports I have gotton reported no problems with my signal,
including those using panadaptors. You mentioned the price, well find a
linear that had the same ability as the Juma PA100=D for less. It looks
like it matches the new TenTech linear for around $700.
I am only a consumer, I have no business interest in Juma but for a little
company started by 2 hams in Finland with a lot of design and engineering
experience, they look amazingly alot like another company we all know when
they first started out (Elecraft). Look at the schematics and read their
theory of operation before you judge the Juma products.

While it is highly desirable to use a clean exciter, The only way a clean
exciter can make a bad amp better is to enclose the amp in a feedback loop
originating in the PA and terminating in the exciter. This can be done in a
rig such as the K3/100 where both the amp and exciter are in the same box
but is near impossible where you are dealing with 2 separate boxes.
Simply: If the Juma is broke, the KX3 can't fix it.
