[Elecraft] K2 to K3 - Outside the Box

[Logan Zintsmaster]

In looking at the K2 schematic, it occurred to me that you could take 
the IF from the Noise Blanker plug, buffer it, and send to an outboard 
unit (how's that for outside of the box thinking) that could have the 
roofing filters and downconverter to the 15KHz DSP IF and then use the 
K3 DSP technology.  You could even have an additional control panel on 
the outboard box to provide access to the K3 functions.  Or you could 
add an RS-232/USB interface and provide all of the control functions 
with a PC. With intefaces to both units, the PC software could merge the 
K2 functionality with the K3 DSP functionality for an integrated system.

Since  the K2 IF is not changed,  you could easily remove the outboard 
box to restore the K2 to its original form.

And for first time purchasers, you'd get something to solder (K2) and 
something to assemble (K2 DSP+). 

Best of both worlds!

Why couldn't there be a  redesign of pieces and parts in the K2 that is a result of the K3  experience.  What would it be to put out a new control board that  takes the lessons from the K3 to the K2?  Like a faster CPU, more  memory, more features, etc.  Maybe buying an upgrade kit (new  board etc) to the K2 in the future turns it into a K2.5/100 or a  K2.8/100.
