[Elecraft] K3 audio

[Don Wilhelm]

Jack,

That may be the reason I do not hear any problem.  My hearing aids do 
not have much response above 3.5 kHz.  If I do not use the aids, my 
hearing drops off significantly above 1800 Hz although my low end 
hearing is about normal for the general population.  Having 'built-in' 
low pass filters is OK at times, but makes it difficult to understand 
normal speech (particularly female and children's voices).

I bow to those with better high end hearing than mine, but to me the K3 
has no audio problems.  Therefore I will make no further comments on 
this subject.

73,
Don W3FPR
