[Elecraft] Strange behavior

[David N.]

Hello all
My K2 has begun to flash back and forth between power reading and frequency. When the power setting is above 10 watts KPA ON I assume.
When you change the vfo it will flash between power and Freq sometimes.
Also with the power display showing it only reads 68 watts flickering 69 watts. But it puts out full power. I assume it is in the KPA 100 but the only thing that I can see that controls the KPA 100 on off is U1 So what does this have to do with reporting? With KPA Off it operates as suppose to. My K2 is going to be the cw rig for our club field day. 3A NFL

Thanks
