No. I have the 13KHz FM filter but the receive bandwidth is still limited to
4KHz.

I can appreciate that for use with PSK Browser software that decodes
everything in the entire passband a wide bandwidth could be useful - just
for monitoring.

However, if you can receive digital signals within a wide spectrum and can
see them on the waterfall then the implication is that you can click on the
trace and reply to them. On transmit, the audio still goes through the
regular SSB filter. Therefore it is better to limit the bandwidth to 2.8KHz
and limit the waterfall to about 400Hz - 2.4KHz within which the K3 properly
set up in DATA A will give the full selected output. Then you won't be
tempted to reply to stations that are actually outside the transmit
passband.
