never thought I'd be so happy with a 150 Hz filter bandwidth. Honestly, the
100 Hz and 50 Hz bandwidths were useless though as the signal level dropped
significantly. It seemed much better a few firmware versions ago, but 150
Hz worked fine for us...I was just getting "greedy" by trying to use the 100
and 50 Hz BW.
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.
