hi cut/low cut not work in CW?

I was doing something odd. Stock 2.7KHz filter, CW mode, V4.61.
Removed all equalization.

Wanted to adjust high cut or low cut. Tapped shift control. Did not
revert to high cut/low cut mode. Ditto for tapping width control.

Can't simulate this with shift because of it's limited range.

High cut/low cut works fine in SSB mode.

Hi Brian,

Turn CONFIG:CW QRQ to OFF.

and/or reset CONFIG:SHIFT=0.01 to SHIFT=0.05

Re: hi cut/low cut not work in CW?

Shift =.05 does do something but the result still is not as expected.us.

Here's the results with a 2.7 KHz filter
First high cut maxs out a 2.0 KHz, low cut can go to zero.

High cut low cut
2.0 no effect
1.8 0-0.2
1.6 0-0.4
1.4 0-0.6
1.2 0-0.8
1.1 0-0.9
1.0 0-0.9

First, why is does high cut not go to 2.7 KHz? BW for this set of data
is 2.7 in the BW/SHIFT mode.
Second it does not appear that the high cut and low cut controls are
independent.

I'm curious about the reason for these observations.

Re: hi cut/low cut not work in CW?

That is the way the DSP is designed. High and Low Cut are limited to
pitch +/- half the filter width. Based on your data, it looks like
your pitch is 500 Hz.

Can't be ... you may have started at 2.7 KHz but BW is defined as
2 x (FH-FC) so as soon as you moved either FL or FH BW changed.
