That's usually been my experience too, primarily because the skirts ring on QRN, and the narrower the filter, the closer those skirts get to the CW note. The closer the ringing is to the CW note, the harder it is for the ear/brain to separate them. This is pretty well known by scientists working in the psychoacoustic world. 73, Jim K9YC ______________________________________________________________ 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
