A few more questions for the experts

6. Hypothetically, let's say, a group of Spitfires is talking to the ground on 347 Khz. A German bomber over the Channel just happens to have his radio man listening to 347 KHz. Theoretically, he could he get a vector on the British squadron, right? Did something like this ever take place?

It is highly unlikely the German crew would be listening directly to the British squadron on their frequency. They would be on their assigned frequencies for the mission the unit was undertaking.

Now indirectly, this did occur.

The Germans, like the Allies, broke the codes and could listen in on most of the Allied communications.

Just like we did, they monitored communications and based decisions off that intelligence. In this case, a controller would most likely vector the formation or alert them of presence of the enemy aircraft.

To facilitate such actions, both sides developed and used IFF or Identification Friend or Foe equipment. This allowed the controller to keep track of friendly aircraft without having to constantly ask if they were friendly. Anything that did not query as friendly, was of course an enemy aircraft.
