Well if i may add in.
Small servers with only a handful of guys all doing the same objective, really there is no need for simple radio as you most likely should all be on the same frequency anyway. Unless you like the fact that you can dial your frequency and talk through it and have radio effects so a little bit of immersion works well. But for unpopulated servers Teamspeak works fine.
However, its when you want to be into something more dynamic like “blue flag”, or to a lesser extent “through the inferno”, is where simple radio shines and teamspeak won’t benefit you much.
So think of a server where you have about 25 players on your side. a GCI, helicopters building stuff, strikers hitting multple targets, transport helicopter trying to get troops to objectives, cap flights and intel flights. Its gonna be a mess on teamspeak. So great aervers like these assign standard radio frequencies for you to tune into to help what you want to do.
A flight goes something like this.
Call in on airport atc to advise taxi and take off from x runway. You also can hear people announcing approach and landing on runways. Really cuts down on accidents at airfields. Once airbourne we can choose a discreet frequency for our flight to chat on and also dial up the gci to co-ordinate our mission.
Gci vectors us to bandits, targets, airfields and we talk on discreet micromanaging our formation or tactics. However, gci is also talking to helo’s and strikers and coordinating the lot.
Lets say, i am a helicopter and there is no gci. I can call helicopter standard freq and see if i can team up with others or assist. I can dial up a sector frequency to see if anyone needs a radar, troop deployment or maybe even a jtac dropped off. I can also call for air cover and if someone accepts, i can monitor their discreet frequency and directly communicate to them.
This is all possible with simple radio. Basically using radios like radios are designed to work. Its great on a populated sever where lots of others use simple radio “blue flag”.
Its free, easy to use install, give it a go! it really does add to immersion and greatly improves situational awareness.
