I agree with Brian, this arrangement works quite well, although I use a 
pair of 1N5821 Shottky diodes in place of the 1N4148 and have also wired 
a 0.47uF (474) capacitor across the straight key.  Without the capacitor 
I got unpredicted errors, possibly caused by stray r.f. in the shack.

My only regret is that the K3 does not have a menu option to accept my 
K2 dual key assembly. Consequently, I have to use a different key for 
the K3.
