That's the latest version, AFAIK. It's been unchanged since 2001. >KFL1-4 Rev B 1.00 (blue trimmers) That's the latest version, AFAIK. It's been unchanged since 2001. > KAT1 Rev C 1.20 There is at least one later version, rev. 1.30. I upgraded from rev. 1.10 about ten years ago, and noticed very little difference. > The K1 power output is showing a solid 5W to a dummy load when > OUT is set at P7.0.

DC supply voltage needs to be around 14 vdc. 2. All the filter board circuits must be peaked optimally. 3. The KAT1 power detection must be properly adjusted. Items 1 and 2 above are your first areas to check, since those affect significantly the actual (as opposed to indiated) power output. Worry about the power indication accuracy afterwards.
