[Elecraft] [K3] need help with hiss on ssb receive

[David Gilbert]

I think it would be far more informative and far less subjective if 
people who feel there is a harsher hiss from the K3 would simply run the 
audio from their rig(s) to the sound card of their computer and use any 
one of several free audio spectrum analyzer applications to display the 
difference.  There are several free web sites where the resulting screen 
shots could be posted for all to see ... and then we might actually have 
something useful to discuss.
