I generally have better luck connecting the Data Out port of the rig into the Line-in on the PC. The Data ports usually have a fixed, and lower level of output, and are pretty well matched to the Line-in on the PC. The Mike input on the PC sometimes has a bunch of extra gain, and is easily swamped, especially from the earphone jack of the rig. My home-brew "rig blaster" is simply a patch panel with a bunch of switches to tie the right rig's Data jack to the PC Line-in, and vice versa with Line-out. Works well.
I copied an image from KO6TZ on the last west coast pass of AO-51 today, way out over the ocean, using this method. The software for my OpenSUSE Linux system is QSSTV, and if I had things configured correctly before the pass started, I might have sent one back...
