[Elecraft] 100 and 50 hz DSP filtering

[Tommy Alderman]

I asked this question almost a year ago but my other brain cell forgot the
answer(s) I got, so in advance I apologize for the redundant question.

On my K3, I have switched between the FIR and the IIR filters when I have
the DSP filters set to either 100 hz or 50 hz, and can tell no improvement.
Why is it that there is a significant drop in signal level (on CW) when
either of those two filter widths are selected? And/or how can I fix the
signal level decrease?

Thanks and 73,
