[Elecraft] [K3] K3 Audio Response - Version 3.33 Firmware

[PA3CW]

I am a CW operator for over 30 years, first professionally and now only as
hobby. My measuring instruments are my ears and the operation of the K3.  I
never had such a good receiver but at first disliked the audio a bit.  It
was written in many postings and many of you gave a thorough technical
explanation even with different 'colors'  of the noise.

Still I trusted on my ears as a judge and i can say that the new release
very much improves the way of listening to CW, SSB and AM signals. The K3
now can really sound the way I like a communications receiver to  do. It is
just a bit 'warmer'  sound than before that makes listening more comfortable
and less tiring.

I still have no clue about the best NR setting. It would make sense to have
some background for which situation which setting is developed.  Also I
sometimes wonder why there is no full decoupling possibility with DSP
technology, meaning what I hear in my headphone is only a clean sinus of 600
Hz, generated by the DSP based on its input .  Is this strange thinking for
CW, or technically impossible? (No immediate feature request ;).

Anyway, thanks for all the good work and 3.33 is an improvement again. 
Compliments for all the development work being done. I am still proud to
operate a K3.
