I have just found out that there is a bug that causes a gain reduction 
just for these two bandwidths if they are set for FIR filters and not IIR.

You can fix it now by switching IIR ON, and when Elecraft fixes the bug 
you can choose either IIR or FIR for these filters as you prefer.

To switch between IIR and FIR, tap '7' on the keypad when you're in any 
filter setup menu entry (e.g., CONFIG:FLx BW). You want it to say IIR ON.
