[Elecraft] k3 NR Audio level increase

[Don Wilhelm]

Terry,

I do not experience anything like that on my K3.  What NR parameters are 
you using?
Are you attempting to use NR at a narrow bandwidth when this occurs?
If so, I can understand why that might occur.

Lyle has explained previously that the NR is implemented in the K3 as 
"signal enhancement" rather than a strict noise reduction.  In other 
words, the passband is examined for content that correlates, and the 
result is amplified.  If the bandwidth is narrow, it is possible that 
the entire passband content (including noise) will appear to be a signal.

73,
