[Elecraft] K3s in WPX M/S - WOW!

[David Wilburn]

Depending on the different bw settings it is off or on.  Additionally 
it toggles if you hit it one too many times.  Could we get a list of 
when it should be on vs. off?  Is it safe to assume that if you are at 
a bw smaller than a xtal filter, it should be on?
