2 years ago, in anticipation of MiG-21 project, I started working on a Croatian Radio Chat module for DCS World.
With the delays associated with the module, the project was sort of, although released in its current state, put on hold.
Now that the MiG-21 module is available, I continued working on the mod, additional voice samples are being recorded (9 people donated their voices for the project ie. player, wingmen, awacs, ground crew, tower etc.) and once that is done, I'm hoping to re-release the version 1.0.
I know it's not a big community compared to others, but I just thought ex-Yugoslav members who are flying this module (as we used to, and still are flying Migs in our respective air forces) might be interested in the project and possibly using the mod (for better "immersion").
Of course, quirks and "bugs" are to be exprected (radio chat contains huuge number of samples) and it's quite possible some of the parts are overlooked and left in their original (russian language) state, but with time I hope to sort those out.
The mod is currently (as you noticed in the link provided) not available, as I'm working on adding additional samples (that have been added to DCS World by ED during the last 2 years).
You can see the old demo of the mod (2 years ago), to get some sort of idea:
Over & Out! :)
