Brian,
A simple stereo to mono adapter may not do that - it depends on how the
adapter is wired.
What is required is that the tip and ring of your paddle plug are both
connected to the tip of the adapter plug. If you have a schematic for
the adapter, that may help - but take your ohmmeter and an empty stereo
plug along to check continuity.

I understand that this can be done by fitting a mono adapter jack on the end of the (stereo) keyer cable jack and plugging it into the K3 "Key" port. I seem to recall reading a caution concerning the use of mono and stereo jacks somewhere in the K3 documentation - but now I can't find it. Is there any reason I couldn't plug the keyer into the "Key" port with a mono adapter jack?
