This product is based on the Tayloe Quadrature Product Detector method to realize mixed frequency. The clock generator Si5351 generates two variable frequency orthogonal square wave signals as excitation, which realizes an ultra-low noise ZIF zero intermediate frequency receiver. The IQ signal obtained after mixing is output to the CODEC codec and collected by the MCU, and the DSP algorithm in the MCU completes the demodulation and display of the signal.

SDR radio DeepSDR 101, digital detuning shortwave FM MW SSB CW HAM radio receiver

Product description

DeepSDR 101 is a DSP digital detuning radio based on SDR software-defined radio architecture. With a spectrum map and waterfall display capability with a width of 192kHz, with 16bit sampling, it realizes a high-dynamic receiver with CW, AM, SSB and FM demodulation functions. The whole machine adopts an all-aluminum alloy CNC shell, with a 4.3-inch 800x480 resolution high-brightness IPS liquid crystal display, while maintaining a small and compact body.

Take it outdoors now and enjoy the natural scenery and the fun of listening anytime and anywhere!

Notes

1. This machine adopts SDR architecture. If you have a strong broadcast transmitter nearby, there may be a serial/mirroring station phenomenon. Please understand

2. The input impedance of the antenna interface is 50Ω. For medium-wave radio, it is recommended to connect an external special medium-wave ring antenna to get better listening effect.

3. Please pay attention to the volume settings of the headphones (EAR) before listening with headphones to prevent discomfort caused by excessive volume.
