Gary, you said: "existing 500 Hz filter (which is too narrow)and their 1 kHz filter (which is too wide)".
500 Hz is too narrow? For what? 1 kHz too wide? For what? What's in this bandwidth gap? I have both the 500Hz and 1kHz filters in my K3, and they are perfect for their intended purpose. I see no need or potential benefit in creating something that would be somewhere in between the two. I'm puzzled by your conclusion that 750 Hz will provide something special. For what and for who? 73, Bob W5OV ______________________________________________________________ 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
