Radio keys communications

[RVG]

Il2 1946 to control the flight group on a single player game I have always used the radio communications to coordinate attacks on one target but in CoD I Think a lot of orders are not working. For example “attack my target” or “tower control permission to take off”. I have always to flight alone and leave my squadron on their own.
Flight alone is boring an never gets the mission success.

,Is the radio keys communication working correctly?
