This USB software defined radio (SDR) receiver is built around the RTL2832U demodulator and R820T tuner, covering a wide frequency range from 24 MHz to 1850 MHz. Simply plug it into a Windows, Mac, or Linux computer to tune into a variety of radio signals using free SDR software.
With the right software, you can receive FM radio, AM signals, CW (Morse code), unencrypted radio communications, POCSAG pager signals, DVB-T digital television (where available), and much more. The MCX RF connector allows you to attach a better antenna using an MCX-to-BNC or MCX-to-SMA adapter.

Jargon buster
Plain-language definitions for the technical terms used above.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- SMA
- A threaded coaxial connector commonly used for antennas. It matters because you need antennas with matching SMA connectors, or suitable adapters, for the LTE and GNSS antenna ports.
