The clock generator Si5351 generates two variable frequency orthogonal square as excitation, achieving an ultra low noise ZIF intermediate frequency receiver. The IQ obtained after mixing is output to the CODEC and collected by the MCU, where the algorithm completes demodulation and display. How to Use: Useaccordingtotheinstructionmanual. Package List: 1 x Radio Receiver 1 x Antenna 1 x Data Cable 1 x Instruction Manual Note: 1. This machine adopts an architecture. If there is a strong transmitting station near you, there may occur cross station or mirror station. Please be aware. 2. The input impedance of the antenna interface is 50. For medium radio stations, it is recommended to connect a dedicated medium ring antenna externally to achieve better results. 3. Before listening with headphones, please pay attention to the earphone (EAR) volume setting to prevent discomfort caused by excessive volume. 1) We accept Alipay, West Union, TT.All major credit cards are accepted through secure payment processor ESCROW. 2) Payment must be made within 3 days of order. 3) If you can't checkout immediately after auction close, please wait for a few minutes and retry Payments must be completed within 3 days.
