RTL-SDR Blog RTL2832U R820T 1PPM TCXO HF BiasT SMA Software Defined Radio 25MHZ TO1760MHZ Dongle (Green)

main improvements: SMA female antenna interface (4.5V DC Bias). Supports high frequency direct sampling mode. Improvements over other RTL SDRs (R820T2, PCB optimization, etc.)

• This is an RTL-SDR software defined radio receiver with RTL2832U ADC chip, R820T2 tuner, 1PPM TCXO, SMA F connector and aluminum housing with passive cooling. Tunable from 500 kHz to 1.7 GHz with bandwidths up to 3.2 MHz (2.4 MHz stable). (HF works in direct sampling mode)
• Ideal for use as a computer-based radio scanner with free software like SDR, HDSDR, SDR-Radio, GQRX or SDR Touch on Android. Works with computers such as Windows, OSX, Linux, Android, and Raspberry Pi
• This model has some improvements over the others. It uses an improved R820T2 tuner, 1PPM TCXO, better components, a redesigned low-noise PCB, cooling improvements, additional ESD protection and SMA F connectors
• It also has a software-activatable bias tee for powering the LNA and active antenna. Complete information on improvements To enable HF reception below 25MHz
