Hello from Kevin, KK4LSG, in Seaford, Virginia. I recently completed my beloved K2 and have been enjoying getting on the air with CW as much as time will allow. I am a new operator, receiving my license in the fall of 2012. I built the elecraft KDSP2 audio filter a few weekends ago, and have been playing around with the settings to find an optimal filter width. I seemingly understand that the crystal filters eliminate much of the unwanted RF from ever entering the circuitry, and that the audio filter further refines the signals before the signals exit the speaker. I currently have the crystal filters set at 1.5 khz, 700 hz, 400 hz and 200 hz. The DSP filters are set to kick in at 150 hz, 100 hz and 50 hz. I read somewhere that the crystal filters do a great job down to 200 hz and that the DSP should be set to go narrower if needed. My question then is whether the collective here recommends similar settings or is there a better way to ensure adequate audio filter functionality without duplicating the efforts of the crystal filters? Is 50 hz too narrow. Are there better settings to help dig out signals from a crowded band? Any help is appreciated as I have found little online that addresses the questions above in a way that I can understand.
