100KHz-1.7GHz Full Band UV HF RTL-SDR USB Tuner Receiver R820T + 8232 Ham Radio
100% Brand New And High Quality
Using the RTL2832 idle channel, broadband connection impedance isolation transformer provides the signal to the signal receiver HF HF bands. And increased input low-pass filter to improve noise performance of the machine. At the same time, it retains the original V / UHF band reception, creative use of studded way to achieve RTL2832 + R820t circuit board assembly and connecting circuits increases, and further improve the overall performance of the circuit. In the homemade circuit board also surrounded, surrounded reserved some help to further develop the pads. The entire circuit is loaded inside a small aluminum to further improve the performance of the overall circuit interference by aluminum shielding.
