Lane,
For my needs I only installed just the 2.8-KHz filter in my KRX3 in
FL2 position to match the 2.8-KHz filter in the main-Rx. Since
bandwidth is set by the DSP and I do very little HF CW, so this is
sufficient for my use of diversity mode.
I have the 13-KHz in FL1 (for FM/AM), 2.8-KHz in FL2 (for CW/SSB),
and 400-Hz in FL4 (for CW) installed in the main-Rx.
I left FL3 position open in both Rx because I chose that when running
diversity reception on digital modes (DATA A, USB) where signals are
output on the 1st IF connectors and bypasses the roofing filters (and
2nd-IF/DSP). I found that having FL2 selected when I run everything
thru my LP-Pan caused a signal "suck-out" near zero frequency, and
was cured by selecting an open filter position. MAP65 uses the
LP-Pan, whereas WSJT10/JT65 uses the normal LINE-OUT from the DSP
section. I would not worry about any of this for your application.
