[Elecraft] K3 Question on Bandwidth setting via Macro

[John Klewer]

I have a macro which, while configuring my K3S for FT8 operation, sets BW
to 4.0 kHz.....the 6.0 kHz roofing filter is (apparently) automatically
selected and I do not actually realize 4-ish kHz BW until I manually select
the 13 kHz roofing filter.

It seems from the Programmer's reference that the XFIL function is a Get
not Set function.

I would appreciate anyone who would set me straight on either what I am
doing wrong or if this is a "problem" that can't actually be solved with
the firmware/hardware as constituted.

Thanks in advance
