[Elecraft] Spurious signal after k2 click mod

Sat Feb 28 23:58:00 2004

I take it back, Vic:  I said in my prior message it is hard to see how 
a mod to the control board could affect the RF, but, of course, there 
is also the change in D36 on the RF board.  And that part is in the 
link between the BFO and the Xmit Mixer.  What is the reason for the 
change in D36?

best wishes,
