Welcome to our store newwellknown.Wish you have a good shopping.
Applications:
An RTL SDR is 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, or for use as a low cost panadapter with a traditional ham radio.
Just search our RTL-SDR Blog website (Google please, links are not allowed on eBay) for your application of interest to see some ideas.

Improvements:
This RTL SDR unit has several improvements over generic and other brands including:
R820T2 tuner
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 signif
