Luc/Wayne, Yes. It does work fine. I have an SGC-230 connected to one of my antennas, also. The only suggestion that I can make is to make sure that the tune power is above the minimum required for the '230. If the SWR is very high before the system is tuned, the '230 doesn't quite make it

Chris, If you are going after the K3 IF output, it is a single audio signal at the IF frequency. You will need to downconvert it to baseband and split it into two streams, one of which will need to be shifted by 90 degrees. It is these signals that go to a good sound card for playing. It
