Hi there,Set the audio panel to com2, not to both.RC will continue to work on com1 but FSATC will only play on the com2 frequency.All the best,John

Ok for the explanation about priorities, I can understand that point.Actually it's not the fact itself of not having ground ACT which made me *complain* about ... but the fact of reading it would be dealt on RC 5 *maybe* ... (so not having to count on it and getting it later)I can also understand about the complexity of the coding involved by ground atc, but I'm sure not to be the only one looking forward (as RC, once airborne, is great and very realistic) to have the same level of atc on the ground as airborne.big deal actually as it is the only big gap in RC4 ... all the other improvements are a matter of bugs, minor improvements, fluidity and so on... nothing that really annoyed me, though it's always a pleasure to feel those little updates while ingame (the speech fluidity for example :) )
