[Elecraft] Regarding the K3 and high QRN levels

[The Smiths]

I've found that if you do the "daughter card" audio mod (3.5Khz audio roll off) on the K3's DSP board that you will find listening to the audio for hours upon hours MUCH easier on the ears.  I was able to tell the difference as soon as I turned the rig back on.  It's not one of those kinds of things that you say "wow, that sounds so much better!" it's more like you say to yourself, wow, I'm not getting tired out listening to all this noise.  It's more of a feeling than a sound.  So when people ask me, does it sound better, my answer is no, but it sure does feel a lot more comfortable.  This could be the fatigue you're speaking about Martin.
