The circuit consists of a frequency-modulated oscillator, a frequency multiplier, an exciter, and a resonance power amplifier. The frequency doubling is determined by the nominal frequency of the crystal and the center frequency of the emission. The crystal frequency of the crystal oscillator of this circuit is 18.667MHz, and the transmitting frequency is 112MHz (this frequency corresponds to the receiving center frequency of SN739 station), so the formula |
