- Software Defined Radio (SDR) is a new type of radio broadcasting communication technology, which is based on a software-defined wireless communication protocol instead of hardwired implementation. Frequency bands, air interface protocols and functions can be upgraded through software downloads and updates, without completely replacing the hardware.
- The 100KHz-1.7GHz full-band RTL-SDR receiver can be connected to computers, Android phones and other devices and use SDR software to receive 100KHz-1.7GHz electromagnetic waves. Support AM, FM (NFM, WFM), CW, DSB, LSB, USB demodulation. It can listen to medium wave, short wave, FM radio, short wave single sideband communication, intercom call, aviation band, etc. (Newly added mute detection function: CTCSS, DCS; Scanner, automatic scanning, etc.).
- Product advantages: medium and short waves directly input the signal received by the antenna to the digital-to-analog conversion chip, which perfectly solves the problems of signal loss, noise, waveform disorder, frequency offset, etc. caused by the use of inverters, so that the sensitivity is improved, and the waveform display is clear Perfect, high resolution, display the actual frequency, including host, small UV antenna, data cable, software and technical support.
FM radio: 87MHz-108MHz, choose WFM.
Medium wave broadcasting: 526.5kHz~1606.5kHz, AM.
Shortwave broadcasting: 3MHz~30MHz, AM.
Airport tower frequency: 118MHz-135.975MHz, AM
Civilian walkie-talkie frequency: VHF: 136MHz-174MHz, the standard is NFM
UHF: 400MHz-470MHz format is NFM
Amateur radio communications: short-wave single-sideband: LSB is commonly used below 10MHz; single-sideband USB is commonly used above 10MHz.
Weight: 150 grams
Ultrashort wave radio station: generally adopts NFM system, the frequency is 50-54MHz, 144-148MHz, 430-440MHz
