Doing so only acts as a roofing filter. With a good enough sound card and good enough algorithms, the terminal program ought to be able to eliminate the interference as well as using a narrow filter in the K3 DSP. If the sound card is adding IMD products or the terminal program isn't designed to detect the signal in the presence of noise, you may benefit from using the K3 DSP as a roofing filter. -- David Woolley "The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio" List Guidelines <http://www.elecraft.com/elecraft_list_guidelines.htm> ______________________________________________________________ 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
