TFAR is one of those things where its as complicated as you want to make it. Me and ads have spent a fair amount of time making it as simple as possible. We use the same freqs in every mission which are listed in the briefing section of the map and adlabs has done a script that (if your group has a team leader) automaticly sets it all up for you so all you have to do is press the transmit key
Theres a little issue where if you dont have a teamleader in your group you have to set the freq yourself, but it takes seconds and you just type it in, press "set" on the radio, and your good to go. It takes more clicks to set off a satchel charge
