John,

Thanks for the tip.

I have a hard time filtering the F.O.D. on the KX3 Yahoo group. I'll go 
back and look there too.

I have set the DLY and finally got it where I can tolerate the key 
clicks, but the DLY is set to about 0.20 - basically, it only clicks at 
the end of transmit.

I *did* notice that even with my MON turned to 0 I still hear key clicks 
in my headphones (I have been wearing headphones the entire time I've 
been testing). I hear them as the rig stops transmitting.
