Hi folks I have end to build the KPA100 few days ago but there's a problem to fix. When drive my Titan 425 gold series with my K2/100 ( nø 5985) have unstable power control ( 20, 21, 23, 24, 19 watts), the grid current and output power jump up and down (tipically 800 to 1100w with 20w input) on every band, specially on 40 and 80m. When KPA100 is OFF i can see very little flutter on simple k2 at 5w... 0,1 0,2 watts of flutter on internal k2 wattmeter Seems not Feedback problem or similar, my antenna is a GP and Ros is perfect... Have read the mods by elecraft:
