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. It would work fine on the low power setting, and would work fine with tuned antennas cut for the band, but when using my 204 foot open wire center fed antenna the tuner would go nut's and cause the radio to reset. Also at times cause some of the presets in the K2 to change when it reset. I could bypass the KAT100, and using my home brew tuner the parasitic would not show up. Tom Hammond, N0SS offered a possible soultion for Stan, so I e-mailed Tom to see what help he could offer. Tom sent me a proposed modifcation to the KAP-100 amp. the required moving the RFC10 that's mounted on the SO-239 over so it is not covering the open slot on the PC board. The modifcation was easy to do and cured the problem in my setup. In my case the RFC was only moved about 1/8", which seemed rather insigficant at the time, but it sure made things work in my K2100 - KAP100 combo. Thanks Tom.
