Oh, I see now what he is saying, I was thinking about the coil as a resonance of some sort which I have seen examples of.
However he got me to thinking about something in regards to demodulating audio off of a phase splitter coil so I will post that and someone might try the experiment of it with real parts to see if it is possible.
