[Elecraft] K-3 Noise Reduction

[goldtr8 at charter.net]

I use the BHI in my mobile rig and could not live without it.  Audio NR 
only effects the spectrum going to the speaker and it really can reduce 
the hiss.

I am going to look at Dayton to see if they have a stereo version, if 
they do I will be bringing it home with me.
