that dose something funny with a low frequency modulation to give a '
rotating ' field , where the phase gives the bearing ?

...will be the vector sum of the two carriers / time and for a
spectrum , then a reference is needed to recover the modulation , CIO ,
to give freq/amp/time , or a complex w/f / time for a detector
alone
That's exactly how VOR works

Hi Group,
What is the mechanism for the way radio signals combine in the air?
For example
1.There are two transmitters each sending out the same fixed frequency
sine wave signal.
2. There are no other signals in space, and no background noise.
3. There are no propagation factors modifying the signals.
e.g. buildings, ionosphere layers.
4. Both transmitters are the same distance from the receiver.
5. Both signals have the same polarisation.
How have the signals combined when they reach a receiving antenna at a
reasonable distance from both transmitters?
It the process addition, multiplication or some other process?
