100KHz-1.7GHz full-band RTL-SDR receiver, can be connected to computers, Android phones and other devices Use SDR software to receive 100KHz-1.7GHz electromagnetic waves, support AM, FM (NFM, WFM), CW, , LSB, USB demodulation. Can listen to medium wave, short wave, FM broadcast, short wave single sideband communication, walkie-talkie conversation, etc. ( detection of mute function: CTCSS, DCS; frequency sweeper, automatic scanning, etc.) Medium and short waves directly input the signal received by the antenna to the digital-to-analog conversion chip, solving the problems of signal loss, noise, waveform clutter, frequency deviation, etc. caused by the use of frequency converters. The sensitivity is improved, the waveform display is clear and perfect, the resolution is high, and the actual frequency is displayed It is very suitable for those who like to build and modify their own equipment. Whether you are an amateur or a professional, this module provides the flexibility and functions required for a variety of applications FM radio: 87MHz-108MHz, select WFM Medium wave radio: 526.5kHz~1606.5kHz, AM Short wave radio: 3MHz~30MHz, AM Tower frequency: 118MHz-135.975MHz, AM Civilian walkie-talkie frequency: VHF: 136MHz-174MHz, NFM UHF: 400MHz-470MHz, NFM Amateur radio communication: Short wave single sideband: 10MHz or less, usually lower single sideband LSB; 10MHz or more, usually upper single sideband USB Color: as shown Material: Metal+plastic Package Contents: 1 * SDR Receiver Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
