Please make a server side scripting command to disable Radio Subtitles.
For example:
disableRadioSubtitles true;
and
disableSubtitles true;
This will be very useful in MP. Sometimes you get messages about enemies, that you even don't see, and the direction.
I consider these automatic reports cheating, especially in TvT's
Subtitles should be a choice of the player, not mission makers.
If you don't want them to hear the radio, use the enableRadio command.
EnableRadio disables both the subtitles and the radio sound. I think the author wants to disable only subtitles.
I found all I need:

But this commands disable side radio, it's not to good for custom radio messages.
