[Elecraft] K2-100 Parasitic

[Ken K3IU]

I also have experienced this problem on 3 different K2/100s. I had moved the
my KAT100 a couple feet from the K2/100 which reduced the magnitude of the
problem. Tuning on low power prevented the problem. After talking to Tom,
n0ss, I moved RFC-10 further away from the RF connector (J2). I'm not sure
exactly how far I moved it but is was probably 2 or 3 mm. I no longer have
the problem. I have moved the KAT100 back beneath the K2/100 and now
experience no problems tuning with high power on 40 meters. I have sent the
info on this to the present owner of one of the other K2/100s that displayed
this problem and will make this "mod" to the third one in 2 or 3 weeks when
the local owner returns to town. After I get my hands on the local one, I'll
put a note on the reflector about the results.

I really don't know exactly what causes the problem or why moving that RFC a
silly little millimeter or 2 corrects the problem, but it worked here!

While reading a post by Stan, W5EWA and his experince with a problems on the
40 meter band with parasitic occilations, I realized that I was also having
the same thing happening to my setup. When using the K2-100 with the KAT100
tuner on the 40 meter band it caused the tuner to act erratic on high power.
