[Elecraft] K3 NR needs improvement

[drewko]

John,

I have adjusted my Rx EQ to attenuate the higher freqs. Also, I
usually have the RF Gain and preamp set so that noise floor is just
audible. My Preamp is almost always off. 

With AF Gain at 12 o'clock and RF Gain at 3 o'clock, engaging NR at
the 1-2 setting is VERY quiet. (This probably depends alot on your
ambient noise and speaker/headphone sensitivity.)

My only complaint about NR is the brief muting that occurs while the
filter rebuilds upon changing bandwidth settings. I would prefer to
hear a noisy signal during this period rather than complete muting. I
have no idea if that is something that could be done in the coding...

I frequently find myself adjusting the RF gain control to the noise
floor, whether i'm using NR or not. I wish there were a single button
push that could do this. Perhaps on some future rig...

73,
Drew
