This is an RTL-SDR software defined radio receiver with RTL2832U ADC chip, R820T2 tuner, 1PPM TCXO, SMA F connector and aluminium case with passive cooling

Tunes from 500kHz to 1.7GHz with up to 3.2 MHz of instantaneous bandwidth (2.4MHz max stable, 3.2MHz if your application is tolerant to USB drops)

HF works in direct sampling mode - V.3 models and above only

Perfect for use as a computer based radio scanner with free software like SDR#, HDSDR, SDR-Radio, Linrad, GQRX or SDR Touch

The Dipole antenna kit is perfect for helping beginners get great reception, the short antennas are great for ADS-B, and the longer antennas work well at the lower frequencies

When used in a V-Dipole configuration the antenna is an excellent option for 137MHz satellites such as NOAA/Meteor M2 weather and the ISS

In the vertical configuration it is great for terrestrial signals, for using custom antennas note that this dongle has an SMA F connector (not RP-SMA)

This model has several key improvements over other models, it uses the improved R820T2 tuner, has a 1PPM TCXO (2 PPM initial offset, 1 PPM temperature drift), has improved component tolerances and an SMA F connector. It also comes with a software activatable bias-tee circuit for powering external devices such as LNA's and active antennas

It also has HF reception capabilities, most standard RTL-SDR dongles can tune down to 24MHz at the lowest. This model has hardware that unlocks the ''direct''

Various other improvements over other models have also been applied, for example a choke has been added on the USB line and additional bypass capacitors and power line ferrites have been added for reduced internal & PC noise, the PCB has been redesigned for significantly lower noise performance, ESD protection has been improved, the front end circuit has been optimized for wideband use (other models are still optimized for DVB-T frequencies), the LDO has been upgraded

Requires USB 2.0 (works on most USB 3.0 ports, but we cannot guarantee it to work on all so please ensure your PC has a USB 2.0 port just in case), installation on Windows is simple

Great for many applications including general radio scanning, air traffic control, public safety radio, ADSB, AIS, ACARS, VDL2, trunked radio, P25/DMR digital voice, TETRA, POCSAG, weather balloons, APRS, NOAA APT or METEOR M2 weather satellites, Outernet, Inmarsat, Iridium, GSM, Milsatcom, radio astronomy, meteor scatter monitoring, DAB
