Hi , I've installed the RCv4 not more than 2 days ago , and I've notice that I can hear the FS2004 ATC on the same frequency and at the same time as I hear the RCv4 ATC. I've try to find anything about this problem on the manual and here at the forum , but no sucess. It looks to me that some aircraft are been controled by the FS2004 ATC and others by the RCv4 ATC. For an example , I was on the tower frequency on KMIA , and the departure aircrafts were talking to the RCv4 , no problems so far , but the aircrafts that were landing were talking to the KMIA tower on the same frequency but controlled by the FS ATC. I'm maybe doing something wrong I don't know , please help :)[]s Fernando
