A few more questions for the experts

[mark@1C]

I can do nothing else,but a Google searching,may it help you.
and this time I will focus my searching on Radio Navigation and so on.
I"m not sure what's your meaning of "quick".If it's not in a very hurry.I can do searching like this every time I've got some leisure.
and maybe you can put some Information Requests to us(all your fans) once a week,for example.I believe it's a pleasure for many fans to help you.

some results from Google about Radio matter,

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
http://home.btconnect.com/gmb/airequip.htm

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

[Crumpp]

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?

5. What color were Italian torpedoes?

rgr, i'll ask for official info.

Yes, on 6th September one of german pilots told to 303. Squadron to break and return to base, and Poles didn't knew that it wasn't tower. That's only example I know.

Get a vector means know their (approximate) location if I'm not mistaken, not the same as communicating with them.

luthier I sent you a PM with lots of manuals for all nations. Should be quite helpful.
