Features: The receiving frequency is 100KHz-1.7GHz, supporting AM, FM (NFM, WFM), CW, DSB, LSB, and USB demodulation. Can be used for listen to shortwaves single sideband communication, FMbroadcasting, and intercom calls. Automatic search scann can be set, and the address of commonly used digital walkietalkie can be cracked and voice signals can be demodulated through software. Built in 1ppm temperature compensation crystal TCXO, making the frequency more stable and accurate. Almost 0 temperature drift, initial deviation of 2ppm, temperature drift of 1ppm (increasing internal chip heat dissipation, making work more stable). Adopting latest RTL2832U+R820T2 solution, supporting XP Win7, Win8, Win10 and other system. Specifications: Material: Metal Receiving Frequency: 100KHz-1.7GHz Application Scope: AM, FM (NFM, WFM), CW, DSB, LSB, and USB demodulation Adopting latest RTL2832U+R820T2 solution: The R820T2 tuner has slightly better sensitivity than the R820T, lower background noise, higher signal-to-noise ratio, and can operate more stably at frequencies around 1.5 GHz. Utilized the Qchannel on RTL2832U to increase direct acquisition reception for frequencies ranging from 100KHz-24MHz. Note: Please allow 1-2cm errors due to manual measurement. Please allow for slight color differences due to different display resolution. Package includes: 1x SDR Receiver 1x USB Cable
