Steve, Have you perhaps increased the value of R98 on the bottom of the RF Board to give you a more stable power control at high power? If so, it will make the power control at lower power more sluggish. That is the only thing I can think of which would make a difference. There is nothing band

Don: Thanks very much for your various suggestions. I have made no mods at all. R98 is the original value. I did not think that there was anything band dependent about the power level. That has led me to wonder if the problem might be a software glitch. The phenomenon does depend on exact

Elecrafters: The seemingly peculiar behavior that I have been observing on 80 M turns out to be normal for a K2. Gary at Elecraft sent me the following message. 73, Steve AA4AK This is just due to the bandpass filter rolloff and the way the ALC in the K2 works. If you test the rig in

This is just due to the bandpass filter rolloff and the way the ALC in the K2 works. If you test the rig in transmit by using the Tune button, the rig will be able to measure and set the RF level better. Some bands have more overall power gain than others. So it is often necessary to
