A few more questions for the experts

found a pic of halifax df wheel


and its location in w/op position

hope this helps

Not excactly the inside of the vents but still interesting:

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.

i agree it would be unlikely for 'listening in to happen
but let's look at the frequencies

http://goto.glocalnet.net/bosradio/S...82overview.htm
wellington radio- slightly more capable than the tr9 receiving from 111kc/s-15mc/s, transmitting 136-500kc/s and 1.5-15mc/s

some info on british radios

now compare to the fug 10 setup in a german bomber
http://www.laud.no/ww2/e10k/index.htm
300-600kc/s and 3-6mc/s

so it is theoretically possible

so it is theoretically possible

I agree it is possible.

I remember listening to Cambodian Army patrols on the other side of the border on a PRC-77 in Thailand when I was in the service. We just happened across their frequency.

Neat presentation on German radios:

If they, the Germans, had the gear to tune in to the British frequencies and use the direction finding antennas to give a bearing to the source what would that tell them?
British fighters over England!

And how hard was that to anticipate?

Actually it is harder in reality than you might think.

Airplanes have a finite amount of fuel with which to find the enemy and fight.

It was very possible to fool the defenses the slip in with little to no opposition. This is why decoy raids and radio traffic deceptions where run.
