[Elecraft] [Bulk] Re: K2 Straight key auto detect

[Peter Eijlander (PA0PJE)]

I did something similar. I soldered a 
two-Schottky-diodes-in-one-package-with-common-cathode device, salvaged 
from a switching PSU, on a 6.3 mm jack, glued it to the base plate of my 
sqeeze-paddle and I just have to plug in my straight key and can 
instantly use both.

This goes into one of the female sockets on a 2x3.5mm female stereo to 1x3.5mm male stereo Y-adapter cable that is designed so one iPod can be shared with two sets of ear plugs. My paddle goes into the other female socket on the Y-cable, and the Y-cable goes into my K2.
