Hi, not sure if I have a problem or not. I'm running 4.3 in FSX and the program works fine. I have MytrafficX installed for my AI and again that appears to be working fine. My query is this, when using RC I don't appear get a lot of AI chatter, yet when I look at the Kneeboard it appears FSX keeps a log of radio transmissions from the AI to it's own ATC and there are lots more messages than I ever hear. Is it to do with the way RC uses more realistic frequencies and control boundaries? Or is there perhaps another reason? If it helps I also have a registered version of FSUIPC and use Activesky.Thanks in advanceSteve

probablyyou won't hear ai/tower chatter when on ground frequencyyou won't hear ai/center other than yours on center frequencyetcjd

JDthanks for that, I thought the FSX log was for AI aircraft on the frequency I was on. I just noticed it today and have never actually used FSX's own ATC. I may do a flight with the default ATC and then the same flight with RC see if there is any difference that way.Thanks for your help.Steve
