From Binding Post to Varnish 291 HERE THE RECEIVERS ARE INSPECTED AND TRIED OUT sets on actual radio-frequency signals. One oscillator is adjusted to a wavelength of 200 meters and modulated at a frequency of 1000 cycles. The second oscillator is adjusted to 600 and modulated at 100 cycles. These testing oscillators are arranged on a loop, and the energy is transmitted to the series of loops shown in the photograph. A receiver must function at both wavelengths before passing the testing department. It has been found practically impossible to locate faults in radio-frequency apparatus unless actual radio-frequency currents are applied to the instruments under operating CABINETS IN THE EARLY STAGES OF CONSTRUCTION
