For those that want to do this (and not everyone want every tom-dick-harry crowding the radio), there is ALREADY a very powerful solution using Discord.
100% user group controllable, and able to interface to the MSFS radio, to dynamically created and destroy), Discord Chat rooms, based on COM radio Frequencies.
In addition, set recording can be assigned to specific frequencies.
Yes, Asobo could attempt to add a Built in solution, but really, they have more important things to do to fix other issues in the sim, and anythung they “throw together” will never be as powerful & flexible as the Discord solution.
Discord also adds, as a standard function, the ability to not only share Audio, but also to stream your Video to all, PLUS a multitude of other function that Asobo might(would) never integrate into a pure FS radio Chat feature.
and of course, Blocking undesirable or unwanted players audio, as well as adjusting individual audio levels, as well as clearly seeing WHO is talking, is already built in.
AND, it available to use NOW… and being used by many.
Yes, I’ll VOTE for it, but I cannot see it happening, and if it ever does, I probably will still prefer the more powerful & flexible FREE Discord solution.
