I built and installed the KSB2 into my K2 awhile ago, rarely use it. Today, used it for SS on 15M and it seemed to work OK. But, with power setting much above 5W, would get the Hi Cur warning. SSBA is 1, SSBC is 2-1, and microphone is Elecraft MH2. Is there a better way to optimize the settings to allow more power? 73, Curt KB5JO
