[Elecraft] K3: Dual key connection

[Dan Barker]

My straight key has a stereo plug with the diodes, and my paddles has a
stereo plug without diodes. They both plug into a small (Walkman sharer)
stereo y-adapter in the back of my K2.

I don't think I'll need a K3, but I'd just lose the adapter and not have to
rewire my keys.

It would be nice to be able to use the same key setup for both rigs.
