How do I disable default FSX ATC?

[GPHowell 0]

Hi,I've got RCv4 up and running (it works fine) but I can still hear the default FSX ATC chatter in the background. I guess the default ATC is still picking up the tuned-in frequencies from RC and registering some of the button pushes (1-9 etc). The default ATC window also pops up from time to time when the ATC gives me an instruction that Ineed to acknowledge.Is there some way to disable default ATC? Thanks

Here you are. It's listed in the FAQ. Also, check the pinned topic above on FSUIPC settings.
