Is the 250 Hz filter a CW filter or a RTTY filter? There's a difference.
I have a 500 Hz CW filter and a 250 Hz CW filter. Other than the normal
reduced bandwidth sound, there's little difference.
Did have a 500 Hz digital (RTTY) filter and it is vastly different than the
500 Hz CW filter. Quit working RTTY so I sold the filter and put in a 250
Hz CW filter. Also have the 500 Hz filter in the 9 MHz IF.
