[Elecraft] NR

[Lyle Johnson]

Vic,

The NR algorithm always works better with a wider bandwidth.  It is simply building a  not-too-narrow filter around what it perceives to be the signal.  

Glad you found it helpful!

The IF NB didn’t do anything against it, and the DSP NB just helped a little. I found that opening up the bandwidth to about 2.2 kHz and setting the NR to F1-3 knocked the radar down enough that I could copy him!
