[Elecraft] Why buy a K3

[Tim Logan]

I've been off the reflector for months, and off the air for months, and 
about to get back on.  Now am seeing the K3 seeming to take the world by 
a storm. In a nutshell, other than perhaps a second receiver - what 
benefits does the K3 really have over a K2 - (in layman's non-engineer 
language :-) Is the difference in specs something I would truly hear? 
Thanks all. 73/Tim NZ7C
PS Does anyone know if the K3 will have much stronger audio than the K2?
