The BBC and "personal messages"

“Les Français parlaient aux Français” (“The French spoke to the French”) on the BBC. It was forbidden and dangerous to listen to them in occupied France. These coded messages mainly served to announce air operations: parachute drops of agents and equipment and landings  of light aircraft that dropped off or picked up agents.
Personal messages also announced D-Day in 1944.
