- I plan to try out some digital modes and wonder if 500 Hz filters are the narrowest reasonable bandwidth to use. Would a 250 Hz filter rule out PACTOR? I haven't operated these modes but want to try,

- 250 would probably be narrow for pactor. The more important feature is the relative phase response of the filter. A Tentec 250 Hz filter may pass pactor unharmed while a 250 Hz Kenwood filter would d

- What radio are you using? With my Omni VI/Opt1 I use the 9 Mhz 500 Hz RTTY filter for PSK31 and find I get great results with it. I've written a macro in MixW that centers that signal in the filter p

- Hi John - Thanks for the detailed reply. First, I am working with my FT 817 for field use. I can get the 300 Hz or 500 Hz Collins mechanical filters for the CW position, but I need to go back and see

- John, I just sent in my registration ofr MixW. I didn't realize that macros of this type could be written for it, but that's something that I want to do. Could you share your macros with us? 73, Mark
