Hi Johnny, You may try seeing what a choke coil in series with the audio to the speaker or headphone does for you. I have the Nescaf filter and really like it for CW. In most cases, its cleaner than the available internal audio filters.
But I found that adding a 3mH coil and 15uF cap in series (set for 750hz) makes a significant improvement removing harshness. I keep my K2's widest filter as wide as it will go, and the coil takes care of most of the harshness. A suggestion for you to check out if interested :-] N1BBR ______________________________________________________________ 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
