Finished the KPA100/KAT100 combo and all seems well. Is it normal for the power ouput to fluctuate a bit during transmit? The manual says it is as the bias is regulating, but it should steady out. When I key down for 5-10 secs, it does settle down. But when sending CW, it does fluctuate still, by as much as 15W. The K2 station here is almost complete. Next up is the 6M transverter. 73 Greg AB7R
