[Elecraft] Configuring DXLabs Suite, Win4K3 and K3 for FT8 etc.

I'm interested in getting my feet wet in WSJT digital modes, but don't know how to configure my K3, DXLabs Suite and Win4K3 to do this. I've checked the K3 manual, Fred Cady's more detailed K3 book and poked around the DXLabs and Win4K3 sites, but don't see how to get started. Can anyone

[Elecraft] K3 - Using Mono Phone Jack Adapter in "Key" Port

I'm considering attempting modify the operation of my UR5CDX CT 755 paddle so that it acts like a cootie. I understand that this can be done by using a mono phone jack adapter on the end of the CT 755 cable (which terminates with a stereo jack) and plugging it into the "Key" port on the K3.
