[Elecraft] Output power on K2 not stabel

[Dick Grolleman]

Hi All

I'm using my K2/100 to drive my Amp with 50 watts. But the output power is not stabel. When set to 50 watt the power goes from 50 to 100 and back, wich causes to much drive for my Amp. Other then that the K2 works fine with 100watts, barefood. 
Any one knows this problem? And more important, how do is solve it.
My K2 is serial nr 4072. It's build in sprng 2004. Rev B  KPA100

Have the K3 on order, have to wait a few more months
