I did this and it helped a bit with the center frequency spike on a PC using cheap on-board sound. I scrounged two 600 Ohm isolation transformers from a couple of old dial-up modem cards I had in a junk box and put them between the radio and the sound card inputs. I think the source of the problem stems from the fact that there were two grounds connected to the radio, one from the power supply and one from the PC. The antenna ground was isolated. Speaking of antenna grounds...
You might also want to make sure your antenna ground is isolated from any other ground. For example use an isolated BNC connector on a metal chassis. Remember, the current Softrock kits have input transformers, so as long as the antenna ground is isolated, the antenna can't be a source of ground loops, although I'm wondering how this might affect lightning protection.
