Re: [Elecraft] KAT500 Fault

Fred, I am now trying the KAT500 output going to a dummy load. When the K3 is set at about 22 watts out, the KPA500 shows 440 Watts out. When I use the Tune feature on the K3 with Manual Tune feature on the KAT500, there is no fault. However, when I send with the K3 keyer and with Manual Tune on
