[Elecraft] K3 audio output v headphone sensitiviy

[David Cutter]

It has recently astonished me just how deaf some headphones are.  In my work 
I was given aircraft headphones that needed 2W to get the same audio output 
as our own make that needed about 20mW.  That quick test with the spl meter 
needs to be repeated on a calibrated jig and I'll be taking my ham phones in 
to get them checked.  I'll post the results here.
