Through SDR software, receiving electromagnetic waves in the range of 25KHz-1760KHz supports AM, FM (NFM, WFM), CW, DSB, LSB, USB demodulation.<br> It can be used to listen to short-wave single-sideband communication, FM radio, walkie-talkie calls, aviation band, meteor monitoring ADS-B decoding radar, AIS signal reception, etc.<br> The analog sub-tone and digital sub-tone can be cracked through the software.<br> Automatic search scans can be set up.<br> The ID of common digital walkie-talkies can be cracked and the voice signal can be demodulated by software.<br> This receiver has a built-in 1 ppm temperature compensation crystal [TCXO]. Make the frequency more stable and accurate. Almost zero temperature drift [2 ppm initial deviation, 1 ppm temperature drift] increases the heat dissipation of the internal chip, making the operation more stable.<br> Using the latest RTL2832U+R820T2 solution [R820T2 tuner has slightly better sensitivity than R820T, lower noise floor and higher signal-to-noise ratio. Can operate more stably at frequencies around 1.5 GHz. ]Using the Q channel on the RTL2832U to increase the direct acquisition and reception of the frequency of 100KHz-24MHz. Realize the full range of 25KHz-1760KHz reception.<br> Support XP Win7, Win8, Win10, for MAC, Android and other systems.<br> Colour:green<br> Material:metal<br> Different batches, there may be color difference.<br> Package Contents:<br> 1xRTL SDR receiver<br> Only the above package content, other products are not included.<br> 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.
