I just registered here because of the same problem.
All the workarounds listed here or in other threads aren't working.
I even deinstalled the game and reinstalled it in another language, downloaded and reinstalled the KA-50 Module via the module manager. Nothing changed.
My wingman in Convoy Hunt f.e. will take off, he will then radio me "Gear up", "Rejoin" and " 2 on your left" or something like that. And that's it. I won't hear orders I give him and he won't neither respond nor react. No matter wether I am airborn or on the ground.
Oddly however, the ground crew will rearm and refuel my Helicopter on my command.
So if this is not a bug, then what am I missing?

Edit:
When I switch to VHF-1, SW or Crew, I can hear my orders to my wingmen, although the comm options are blacked out. Yet they don't react.
When I swicht to VHF-2, nothing happens.
