I can't see the point of it in il2. DCS yes where you can actually operate the radio, il2 you can't so no point imo.
Even in DCS unless your going hyper realistic, it can be a faf.
It's even installed and ready for use on our server, not currently running though ... there appears to be no need for it within our group.
We got TS, which works fine for our purposes. If you have a need for more realistic radio, crackling and stuff, then it could add to the immersion.
