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! 73, Ken K3IU -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of walter renner Sent: Sunday, May 14, 2006 7:54 AM To: ElecraftList Subject: [Elecraft] K2-100 Parasitic 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. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
