How to get a realistic sounding radio transmission?

[nigelmcelwee]

I notice on the network some guys it actually sounds like they are on a VHF radio. When they call in you can hear a static"y" sound with their transmission as if they are actually transmitting wirelessly.

Is there a way to simulate this affect on the sound cards so that when I hear transmissions from ATC is has a bit of static and realism to it?

I know somewhere in this vast forum that this has been discussed before...I will try and search for it.

AND HERE IT IS!!
