Schematic Symbol

In this schematic,

At the top middle there is a symbol "ODD" that is enclosed in a circle. Can anyone tell me what that is? Im assuming it is the audio jack, but i may be wrong,

Thanks

Bad schematic it is a sensor of some type ODD is the authors symbol, if this is a Theremin it is an antenna.

From the site it looks like the connection point for the second oscillator B circuit.
