Hi Chuck, I didn't have another paddle to try, but all of my testing has shown that choke RFC4 was to blame. It's wide open with no continuity. I have since bypassed the choke with a piece of wire and now everything works properly. I'm still waiting to hear back from Dale whether or not he will send me a replacement choke, or if I should just send the K3 back to Aptos.
