[Elecraft] Making K3 RX audio like K2

[NZ0T]

Thanks Lyle, I had not thought of changing the delay on afx which I use all
the time.  I wear hearing aids which may be part of my problem though I take
them off when using headphones.  I'll try PB2 in CW and see how that works. 
Don't get me wrong - the audio od the K3 is excellent just different than my
K2.
