Hi all, Running my K-3 at 100w into low SWR antenna. Started a transmission and all fine. Instantly the output went to zero. Tried a reset. Still zero. I checked the Config menu setting under KPA and it is set to PA nor. Lowered power to 10 w and the output is fine. Adjust it past 12 w and the output goes to zero. Any suggestions? 73, Art KZ5D
