We sometimes pick up messages which are not intended for us; so we must keep our receiver in perfect Syntony of reciprocal vibration with the stations from which we require to receive messages, to the exclusion of others which would produce confusion.

This is what in the language of electrical engineers is called "Syntony," which means being tuned to the same rate of vibration, and no doubt it is from some such cause, that we sometimes experience what seem inexplicable feelings of attraction or repulsion towards different persons.

The most effective arrangement is one in which the radiator draws off gradually a large supply of energy from a non-radiating circuit, and so sends out a true train of waves, and not mere impulses, into the ether, and as we shall see later on, it is only when the radiation takes place in the form of true wave trains that anything like Syntony can be obtained.
