There are two levels of filtering going on. The DSP (software) filtering is independent of the crystal roofing (hardware) filtering. You set the roofing filters to automatically kick in to match what you dial for the DSP. You have to tell the radio what filters you have installed and when you want them to kick in. It is all in the menus. I have mine set up so the 500 hz roofing filter kicks in when I reduce the DSP to 600 hz.
Sounds to me like you don't have the filters coordinated. Buck k4ia k3# 101 In a message dated 7/14/2010 10:45:38 A.M.

This is true? So that´s means I don´t need the KFL3A-250 250 Hz, narrow 8-pole filter to narrow less than 400Hz? 73, Jorge CX6VM/CW5W K3 #4077 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
