[Elecraft] Filter help

[Bill W4RM]

I just install filters in my sub receiver to match my main receiver (1.8,
1.0 and 400Hz).  I have configured them using the K3 utility SW program and
it looks like they are set correctly in the program.  So now how do I make
the sub receiver track the filter setting of the main receiver?  I.E. if I
go to CW and select the FL4 400 HZ filter on the main receiver the SUB
receiver doesn't  sound like the filter is selected.  Same case in SSB with
1.8khz filter.  Also I don't understand how to manually select a filter on
the sub receive like I can on the main receiver using the XFIL button.

 

Any help would be great.
