[Elecraft] K3 Button Box

[brian]

N2TK suggested that I post this.

If anybody wants to try HBing an external "button box" for the K3, I 
have a 16 button design which uses a $5 PIC.
Sits next to my keyboard.

It connects to the K3 via serial port to the station computer.   K3 port 
sharing software is required.  Some free software products work.

Glad to send schematic , pix of final product and some notes.

No doubt a professional could create a better product but it works for 
me OK.
