So I've been enjoying other games and sims..and one newer one on the market, a tactical FPS set in the realm of modern combat, and is squad based, has native VOIP. You've got two options, local and group transmit (IE in your immediate area and one for your squad) and you don't need to mess around with anything. It simply recognizes when you have a microphone and transmits.
Would it be possible for something similar with DCS? No messing around with a 3rd party app (IE SimpleRadio), TeamSpeak or Discord..just..get in, set the radios, and transmit.
