I remember seeing it said that, using the NR was useless when you were using narrow cw filters
6) NR is rarely useful if the bandwidth is narrow. If you set your CW width to 400 Hz or less, for example, there is no point in running NR *unless* you want to use it as a sort-of "smart squelch." http://www.elecraft.com/K3/Lyle%20Johnson%20explains%20Noise%20Reduction.htm GB & 73 K5OAI Sam Morgan On 12/7/2010 2:18 PM, k5nu wrote: > Fellow Elecrafters, > > Many of you have praised the current version of apf.
