Don,
As always, thanks for your reply.
I can confirm that I *DO* get distortion when operating into a dummy load. I
can also confirm that I have the distortion when operating with nothing but the
microphone and antenna connected to the K2.
The K2 itself is Rev G dated May 2007, with errata to G-5 (March 2008). The
KPA was purchased with the K2 in July 2008, and is Rev E, dated Jan 2007. The
KSB2 was also purchased with the K2, and is Rev E dated Jul 2004. According to
the Elecraft web site, the KPA100UPKIT is for KPAs prior to Rev D.
ALL cables used for my testing were exactly the same for the K2 and the FT-897
and the IC-746. That includes the power supply cables, the coax from the
antenna to the tuner, and the coax from the tuner to the rig. I used the same
Signalink with the same USB cable (although, of course, the mic cables were
different).
I have not added any additional components to the Elecraft products. They
contain only those things that Elecraft included as specified in the Elecraft
assembly instructions.
