Air Traffic Control on PC

Air Traffic control broadcasts from 108 - 138 MHz. (http://www.instructables.com/id/Transistor-Radio-Hack/)
A couple of months ago I bought a Realistic Jetstream radio. It was used. I saw it there before. I finally bought it. I thought it was just an FM/AM radio. It said AM/VHF. I thought that was odd. After I bought it I realized that it wasn't an FM radio, it was an Air Traffic Control scanner! That was even better. It comes apart just like the radio Kipkay used in the hack. It was already an ATC radio though. My question is there any way to get Air Traffic Control on your computer? I tried an old tv tuner card. I set the frequency to 122.8MHz. That is the frequency for the local airport in Microsoft Flight Simulator 2004: A Centruy of Flight. It is also what my radio picks up. The antenna won't pick it up on the tuner. FM radio works though. I hope all this makes sense.
