The given work is devoted to the study of SDR devices and the principle of their work. The aim of the work is to study the feasibility of implementing your own SDR receiver designed using Arduino, as well as to consider the characteristics and advantages of the resulting device. By carefully monitoring the signal path of the receivers of the SDR systems from entering the antenna to leaving the digital signal processing device, we studied the principle of software- defined radio and features in comparison with traditional superheterodyne type radios. As a result, the HF receiver architecture of the SDR system was proposed, and the capabilities of the proposed solution were considered.
