[Elecraft] K2-100 birdies

[K6MR]

I know I've read this somewhere, but searching the archives didn't bring 
anything to light.

Both of my K2-100s have birdies around 14.068.  They pulse on/off, and 
change frequency slightly when you turn the power knob to activate the 
KPA-100.  I'm sure I read somewhere what to do to move these out of the 
band, but no luck in my search.  They are some sort of mixing harmonic 
since they change frequency about 4 times faster than the tuning knob 
actually tunes. 

Anyone remember what to do?

tnx,
