Radio transmission interrupted when other radio triggered (on different channel)

[Jenson]

Hi all, at first I thought I set something wrong in the ME but now I tend to think it is a multiplayer bug.

I have created multiple triggers for different clients in a Multiplayer mission, these triggers will activate a radio transmission over a s specific frequency, when I played the mission with my friends (we tested 4 times already). We found that a radio speech will be muted/stopped if another player triggers another radio speech in a different frequency. I'm wondering if anyone else also encountered this issue before? And if there a better way I could find the reasons for this problem? 

The original post is here (maybe admin can merge both posts). Thanks a lot.
