DIY R2017 Aviation Band Receiver Aircraft Band Receiver Kit Audio Receiver Module Kit
Description: Circuit principle: Antenna to receive signals first enter a bandpass filter, bandpass filter function is to ensure that the 118 MHZ to 136 MHZ signal can be put into CD7358 high, other signal is maximum attenuation. CD7358 internal have a voltage-controlled oscillator at the same time, the frequency changes in D2 junction capacitance, design covers about 120 MHZ to 150 MHZ. Power supply: 9-12 v Antenna: 50 ohms, is not balanced Typical receiving current: 30 ma Receive frequency: 118 MHZ to 136 MHZ Working pattern: AM Package Included: 1 x DIY R2017 Aircraft Band Receiver Kit
