I. OVERVIEW The oscillator frequency discussed in this article ranges from 99.766 MHz to 101.666 MHz for a total of 20 channels with a channel spacing of 100 kHz for local oscillation of the glide receiver for the aircraft’s instrument landing system. Frequency according to the unified ICAO regulations. The oscillator consists of a transistor as oscillating tube, 20 crystals will be required by the electronic switch
