Note: 1. RTL-SDR cannot receive short-wave, because the RTL2832U chip of RTL-SDR itself does not directly support short-wave reception, because it lacks the direct downconversion function of the band (below 24 MHz), so RTL-SDR cannot receive short-wave due to hardware limitations. If you want to receive shortwave, it is recommended to choose SDRplay RSP. The SDRplay RSP is a high-performance wideband SDR receiver with a frequency range of 1 kHz - 2 GHz covering the shortwave band.
2. The mobile phone only supports the Android system, the computer only supports the win system, please be sure to confirm that your device operating system meets the requirements before purchasing, to avoid being unable to use it due to compatibility problems.

Product advantages: The short and medium wave directly inputs the signal received by the antenna to the digital-to-analog conversion chip, which solves the problems of signal loss, noise, waveform chaos, deviation frequency, etc., caused by the use of frequency converter, so that the sensitivity is improved, and the waveform display is clear and complete, the resolution is high, and the actual frequency is displayed.
Software Defined Radio (SDR) is a new type of radio broadcast communication technology, which is based on software-defined wireless communication protocols rather than hardwired.
100KHz-1.7GHz full-band RTL-SDR receiver, which can be connected to computers, Android phones and other devices, and use SDR software to receive 100KHz-1.7GHz electromagnetic waves, supporting AM, FM (NFM, WFM), CW, DSB, LSB, USB demodulation. It can listen to medium-wave, short-wave, FM radio, short-wave single-sideband communication, walkie-talkie talk, etc. (Added dumb sound detection function: CTCSS, DCS; Scanner, auto-scan, etc.)
