Not sure, David, if your Q was to me or to Hank. I can only answer for me.
When I adjust the filter width knob, I'm most definitely hearing the combined effect of the DSP bandwidth reduction and the change in roofing filters. But, since I can change DSP without changing the roofing filter (by stepping from 1500 Hz down to 550 Hz) I can get a good feel for how the DSP filter sounds. Then, stepping to 500 Hz, I can see the combined effect of one more DSP step plus the insertion of the 500 Hz roofing filter. The observed big change from 550 Hz to 500 Hz is *mostly* due to the roofing filter. - Keith N1AS - - K3 711 - ----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Fine observations when you change the filter setting knob, but what makes you think you are hearing the effect of the roofing filter and not the dsp filter?
