The K3 has an AGCP (AGC Pulse) function which is designed to solve this 
problem. It is adjustable for the length and amplitude of pulse widths 
that are to be considered noise, and which should *not* trigger AGC. I 
have tested it (at least in the beta firmware you can turn it on and 
off) and it is very effective.
