[Elecraft] RE K3's NR feature

[John Lawrence]

After working lots of low band and 6 meter weak DX I fully concur with the latest reviews covering the NR feature and its ability to reach into wide varieties of QRN and pull out the signals.  I will add that when using this feature for weak signal DXing,  increasing the bandpass filtering allows the the DSP to produce improved signal detection thru/in the noise.  At the same time, it also helps if there is less adjacent frequency QRM giving when listening down deep using this DSP based feature.  When I narrow up the receiver bandwidth there is less chance of seeing NR improvement.
