At long last I've finally gotten around to putting the coax and interface cord on the Softrock Lite II receiver. The cord to plug into the sound card came from some old discarded speakers, and the coax is a short length of RG58 with an SMA connector that I picked up a while ago. I was originally going to use it for an antenna project for the VX8-DR, but figured I could always get another one later.
Now I just need to find some time to get it on the air. If I want to use the antenna, I'll have to find an SMA (female) to SO-239 adapter, or make some jumper wires to connect the ends.
