[Elecraft] K3 6KHz Filter and Data Modes

[Bob]

Hey,

My widest filter is currently a 2.8 KHz on the main board.  If I understand
things correctly, if I shift all the filters over a spot, then pop in a
6KHz AM filter for FL1, I can use that for TX and RX Data modes.

The reason I ask is that the WSJT-X program is now supporting a full 4KHz
wide waterfall that allows both JT65 and Jt9 QSOs.  With my current filter
I can clearly see the upper end cuts off around 2900 Hz.

So my question is would there be anything else in the audio or DSP chain
that would prevent me from using the full 4KHz of WSJT-X while in DATA
modes if I have a wider filter in slot FL1?

Thanks in advance,
