Dick, I agree completely. Perhaps I was not clear. The P3 coupler normally goes - not between the K3 and the KPA - but between the KPA and the tuner so that It shows the "adjusted" SWR as "seen" by the KPA.
The KPA1500 has a tuner built-into the same case. Jim - W4RKS ---------------------- Original message: Am not sure why you need a tuner between the radio and the amp in the first place?? As of now, I have my K3S or K3 driving a Alpha 9500. I never have used the tuner in either when driving the amp? I assume the KPA9500 will have a 52 ohm input, and you would not need a tuner.
