[Elecraft] CW Paddle A/B switch

[James K4JK]

I have done this with a repurposed A/V selector switch and custom-made
cables.

Amazon has a cheap one that worked for me:

S-video is 4 conductor, so that was used to switch the key between the
radios. I just wired up old 3 conductor 1/4" cables to svideo (mini-DIN)
plugs purchased from ebay. Make sure you keep the pins straight or your
paddle could be reversed when you switch between radios!

Audio was handled by the RCA jacks and adapter cables. Monoprice has all
kinds of cheap cables/adaptors if you don't want to make your own. But you
will probably have to build mini-DIN -> Stereo cables yourself.
