Hey Saber,
My DCS is pretty stock, VIACOM Pro and my trackIR/Oculus. No other mods at the moment. Radios set to easy comms and I can verify they are going to the proper channels. 124.0, 30.00 and such. I have it not trigger in the first mission too but with repeated attempts it worked. I get the same results with ViaCom as without it too. I was only doing the mission, they are straight forward enough and only did the training for the first TAC11 and the second I decided to to just do the actual mission. I just purchased these, basic, tac 1/2 in the last sale so they are up to date and I’m on the latest version 2.9 release. I’ll be away for a month for work but I wanted to share my information while it was still on my mind. Cool campaign, kind of a bummer when you can’t get it to cycle through the JATAC’s though. The A-10 is so fun to use. Also, I was in the A-10C II in case that matters. Oh and I forgot I have SRS but nothing bound to it. Not that into multiplayer at the moment and I fresh installed everything after the last big update to DCS.
