Barkhausen-Kurz Oscillator Operation with Positive Plate Potentials

The experimental results presented in this article are chiefly concerned with the wavelength-plate-potential characteristic and the oscillator behavior. They indicate that the wavelength characteristic has two discrete portions, one containing a long-wave class of oscillations and the other a shorter wave class. In the particular experiments described, these two were found to be separated by a short interval in which the oscillator functioned unstably. The results further reveal that this type of generator will operate only while the plate potential remains below a certain critical value.
