Around 8 hours of military aviation radio chatter that I got from red flag training exercises and other military aviation audios that converted to ogg audio files of 1 hour + each ready to add them to any mission in the mission editor.
It adds a good radio chatter to the mission and, in my opinion it helps with the immersion
*Recommended*.
In the mission editor, add the audio as "radio transmission", set your AM radio channel and it's ready to go, power for the transmission I always put it at 10000
I personally put it on "loop on" in case the mission is longer than an hour
