[Elecraft] K2 vs. K3 Rcvr

[Ariel Jacala]

Bert
The specs say it all.  The K2 is no slouch compared to the K3 in terms of MDS (Minimum discernable signal), BDR (Blocking Dynamic Range) and such.  The K3 begins to have an edge in terms of IMD (intermodulation distortion) and phase noise.  In that sense I believe the K3 is a better contesting rig specially when you add the bells and whistles.  There are other advantages to a K2 - such as current draw - as low as 200mA versus the K3's 800mA which makes it better for portable ops using batteries - better at conserving energy and it is much smaller - even as a K2/100.  Plus you have the bragging right of having almost as good a receiver as a K3 which you soldered together.
See the ARRL and Sherwood specs on the Elecraft page.
