[Elecraft] 250hz Filter - Audio drops

I don't see that behavior here.  Make sure that your SHIFT center 
frequency equals your PITCH setting.

Subject: [Elecraft] 250hz Filter - Audio drops

This is driving me crazier!
My narrow filter is 250hz (FL4). FL4 cuts in when I change my DSP 
filtering
to 250 hz, as it should. FL4 stays in as I make DSP more narrow, 
all the way
to 50 hz.
The problem is that when I change DSP from 150hz to 100hz or to 
50hz, my
audio output seems to drop tremendously, to the point I have to 
increase the
AF gain to hear the intended signal. The audio does not come back 
to
'normal' level until I change DSP from above 100hz bandwidth.
I have FL4 set for 2dB gain; FL4 FRQ set to 0.00.
Would appreciate any suggestions to fix this as I hope it is not 
'normal'
operation?
