Doug's last sentence is a very astute observation from someone who is
clearly an experienced contester.  It's probably the major reason I try to
avoid extremely close spacings.  Sure we can use 200 Hz bandwidths to
eliminate QRM but we have no control over the guys who call off-frequency. 
I'm hoping the K3 with its CWT function becomes more popular and helps
reduce the range of off-frequency callers.
