Well, the good news is that everything is working fine. I actually had two of the RF cables reversed - tried to make the connections from memory - not smart.
This turned out to be a very easy exercise, and I like the result. Now I keep the K2 in "barefoot" configuration, and the KPA100 and tuner are both outboard. The only extra thing I had to do while making this modification was to scrape paint from the side panels to get good ground connectivity. I don't think the instructions for the KAT100-2 ever told me to do so. Thanks for your help and comments. 73, Tom KG3V On 9/7/07, Dave Van Wallaghen <[EMAIL PROTECTED]> wrote: > Hey Tom, > If I'm reading what you wrote correctly, it looks like you have it connected > correctly.
