Software Defined Radio (SDR) Receiver – 100KHz-1.7GHz Features: The antenna's received signal is converted into data via the receiver and sent to your computer, Android phone, and other devices via the USB interface. Software processes and decodes the signal, displaying the spectrum and allowing for customized reception adjustments. Supports bandwidth, signal recording, backup, and playback functions. Through SDR software, it supports the reception of electromagnetic waves in the 100KHz-1.7GHz range: AM, FM (NFM, WFM), CW, LSB, and USB demodulation. Can be used for shortwave single-band communication, FM broadcasts, walkie-talkie conversations, airbands, meteor monitoring, ADS-B decoding radar, signal reception, etc. Analog and digital subtones can be decrypted via software. Automatic search and analysis can be set. Software can be used to decipher the identity of common digital walkie-talkies and demodulate the voice signal. Color: Gold Material: Metal Technical Specifications: The receiver has a built-in 1ppm temperature-compensating crystal (TCXO) for stable and accurate frequency. Near-zero temperature drift (2ppm initial deviation, 1ppm temperature drift) increases internal heat dissipation from the chip, ensuring stable operation. Uses the latest RTL2832U+R820T2 solution (R820T2 tuner offers slightly better sensitivity than R820T, lower noise floor, and higher signal-to-noise ratio; operates more stably at frequencies around 1.5 GHz). Uses the Q-channel on RTL2832U for direct reception of frequencies from 100KHz to 24MHz. Full reception from 100KHz to 1.7GHz. Supports XP, Win7, Win8, Win10, Android, and other systems. Due to different batches, there may be slight differences in appearance, color, and printed text on the product.
