This is the RTL-SDR Blog V4 software defined radio receiver with an RTL2832U ADC chip, R828D tuner, 1 PPM TCXO, SMA F connector, built-in HF upconverter, improved filtering and an aluminum enclosure with passive cooling. It tunes from 500 kHz to 1.766 GHz with up to 3.2 MHz (2.4 MHz stable) of bandwidth.
It works with the latest software such as SDR#, HDSDR, SDR-Radio, GQRX or SDR Touch on Android. It runs on Windows, OSX, Linux, Android and computers such as the Raspberry Pi.
It uses the improved R828D tuner, a 1 PPM TCXO, better components, a redesigned lower-noise PCB, cooling improvements, additional filtering, additional ESD protection and an SMA F connector. It also has a software-switchable bias tee to power LNAs and active antennas.
The RTL-SDR Blog V4 R828D is a popular software defined radio (SDR) receiver used to receive a wide range of radio frequencies. Here is a summary of its features, specifications and applications:
