Jack, I finally have some good data on my problem whereby I can’t get full output from the KPA500 on 6M. As you might remember, as I raise the drive and get beyond about 200 watts out, I get a HI SWR fault. I’m sure now that it’s a K3S problem. Someone on the Elecraft list suggested that the K3S might be generating a spurious frequency that would confuse the KPA. To test this, I brought over an ICOM IC-706MKIIG and hooked it to the KPA. No problem at all getting full power out! Additionally, the KAT500 tunes the beam to 1:1 with the ICOM driving the KPA. With the K3S connected, the KAT500 tunes to about 1:8:1. The KAT500 should not operate any differently with different driving rigs. I’ve tried different jumpers between the K3S and the KPA with no difference.
