I generally operate in a fairly low noise environment and little strong  
signal interference.  Still, it is nice to learn the KX2 has such  
safeguards built in, especially since I plan on using mine at a 2 or 3  
station FD operation shortly and been wondering about what effect the SSB  
QRO station next to me will have.  I feel better now.

What?  No Crossed whip anti-overload vectorized buffer disrupter sensor?
