I don't have a 700 Hz filter (yet) but this is what I'm thinking. I've discovered that the K3 NR is more effective if the DSP bandwidth is set to 1 KHz or so. When I'm searching for or copying a weak CW signal I often get AGC pumping from a strong signal close by but outside the 1 KHz passband. The 700 Hz filter would solve this.
I currently have the 400 and 2700 Hz filters. 73, Brian, K0DTJ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
