  Tom,

I know nothing about that particular amplifier, but I offer a few "in 
general" facts.

Pops in the K3 audio while keying an amp could be a sign of "hot 
switching" in the amplifier.  Try increasing the keying delay in the K3 
to see if that eliminates it.  If not, check the relay "pull-in time" 
for the amp (plus any contact bounce time), and if it is not within the 
K3 Key-to-RF onset time, you will not be able to use QSK with that 
amplifier unless you can speed up its T/R relay.
