With some thought would it not be possible to get 500 and 200 Hz 
filters with matched offsets so one could use bandwidth diversity 
in addition to antenna diversity?  I will not be able to try that 
with my first K3 when that KRX3 arrives since the existing 500 
and 250 Hz filters have different offsets but I will look at the 
200 Hz filter in the second rig to see if it is close enough to 
the -790 Hz (measured in radio #1, specified for radio 2) to be 
useful. 

73,
