No, don't have the RCA cable - only the K3-->KAT500-->KPA500 cables. What I do have is an inability to read and pay attention to what I'm reading!!!
Good grief - I had been using a third party tuner until I put the KAT500 together and the process is a tad different. Now I see what was happening. The tuner already had a match and did not bother to disable the amp when I pressed the tune button on the K3. Also, after re-reading the manual, I see that pressing the tune button on the KAT500 will force a re-tune when the K3 sends RF. Once again, operator. A learning process... Thanks for the help!
