How do I tell if it uses AM or FM transmission signals? The diagram
shows nothing in reference to a FM or AM transmission bands.


For one thing, the audio input is fed directly to a transformer in the plate
circuit of the oscillator tube. Classic AM.
Next, the oscillator is fixed at 1 MHz by the crystal. No audio gets into the
oscillator grid or cathode to FM it.
