[Elecraft] K3 x K3S - Is There a Difference from an Operational Standpoint?

[W3FPR]

Michael,

 From an operational standpoint, they are almost identical.  The K3s 
does have the USB interface on the back panel, where the base K3 has the 
RS232 interface instead.  Other than that, the K3 nifty manual should be 
good.
