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 100 kHz to 1.8 GHz with up to 3.2 MHz (2.4 MHz stable) of instantaneous bandwidth. (HF works in direct sampling mode). Perfect for use as a computer based radio scanner with free software like SDR#, HDSDR, SDR-Radio, GQRX or SDR Touch on Android. Works on Windows, MacOS, Linux, Android and single board computers like the Raspberry Pi.
Great for many applications including general radio scanning, air traffic control, public safety, ADS-B aircraft radar, marine AIS, ACARS, trunked radio, P25/MotoTRBO digital voice, POCSAG, weather balloons, APRS, NOAA APT/Meteor M2 weather satellites, radio astronomy, DAB, or as a low cost panadapter with a standard ham radio. Features
This RTL SDR unit has several improvements over generic and other brands including:
Improved passive component tolerances
A 1 PPM temperature compensated oscillator (TCXO)
HF mode via direct sampling built in (can tune down to 500 kHz unlike basic RTL-SDR's which can only go to 24 MHz)
SMA F connector
Aluminium shielded case with thermal pad for passive cooling to improve L-Band performance
Software activatable 4.5v bias tee circuit
Improved PCB design for lower noise and less spurs
A USB noise choke, more bypass capacitors, and built in ferrites for less PC noise
Improved ESD protection (additional ESD diode and extra ESD discharge paths)
An improved front end circuit designed for wideband use (other models still use a circuit designed for DVB-T only)
Several breakout pads on the PCB for advanced users
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 500 kHz to 1.7 GHz with up to 3.2 MHz of instantaneous bandwidth (2.4 MHz max stable, 3.2 MHz max 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 on Android. Works on Windows, MacOS, Linux, Android and even embedded Linux computers like the Raspberry Pi.
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 24 MHz at the lowest. This model has hardware that unlocks the "direct sampling mode", and allows for tuning down to 500 kHz. There is a built in 25 MHz low pass filter for optimizing this mode.
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, and several break out pads have been added for advanced users.
The device 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 native USB 2.0 port just in case). Installation on Windows is simple, This model has several improvements over other models. It uses the improved R820T2 tuner, a 1PPM TCXO, has better components, a redesigned PCB, cooling improvements, extra ESD protection and an SMA F connector. It also has a LNA(Low noise amplifier).Requires USB 2.0 or newer. Features on DVB-T +DAB+FM+SDR RTL2832U R82T2 TCXO + HF. Please feel free to contact us for support. As the dongle heats up from use, the oscillator will experience thermal drift, causing the frequency offset to change. The TCXO should be immune to this problem due to it’s temperature compensation circuitry. To test the temperature compensation, we cooled both a TCXO dongle and a standard dongle down in a refrigerator first to simulate cool climate conditions. We then measured the change in PPM offset after 30 minutes of dongle operation. As expected, the TCXO had almost zero drift after 30 minutes (
