Further to this, I find using VOX with a short timeout (0.3 sec) 
provides an "almost" gate, and allows fast voice break in.  It also does 
not generate any distortion of the low-amplitude portions of the 
transmit audio that a downward expander inherently creates.  With the 
fast attack action of the K3 VOX, such short hold times are practical.

Enjoy!
