“ The operator will find “A” and “G” never need a large capacity. The whole secret of getting effective results from this connection is to tune the condenser combination properly. That is, to vary the capacity of the various condensers so that the Audion will oscillate. Once the Audion is generating undamped waves, the set is tuned with the loose coupler and the signals heterodyned. This merely means “beats” are produced. The operator can vary the frequency of the signals at will, as the “beat” frequency depends upon the capacity of the condensers. ”

“ Any amateur who carefully reads the suggestion given, should have no trouble operating an oscillating Audion with an aerial of fair length. Amateurs throughout the country are now in a position to receive signals from distances of several thousand miles. ”

“ The writer has not gone into a detailed account of loose coupler construction. The average amateur understands the manufacture of a receiving transformer and should have no difficulty in constructing one with the above dimensions. ”
