Important Note on Avoiding RTL-SDR SCAMS:<br>Note that the<br>profile<br>"<br>rtl-sdr-blog"<br>is the official eBay account for RTL-SDR Blog.<br>Please confirm the seller name before purchasing as it has come to our attention that there are scammers copy and pasting this listing and selling this item at a very low price, or sellers selling low quality counterfeit RTL SDR V3's. Most of these scammers have no intention of posting anything out, and will simply take your money and run.<br>Some scammers are also advertising green/blue and more squarish silver dongles under our brand name "RTL-SDR Blog". Those are not our units and do not offer the same performance/features.<br>Includes<br>1x RTL-SDR Blog brand R820T2 RTL2832U 1PPM TCXO HF Bias Tee SMA Dongle (V3)<br>Note that no antennas are included in this listing. Please see our other listings for a listing that includes an antenna kit.<br>Applications<br>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.<br>Just search our RTL-SDR Blog website (Google please, links are not allowed on eBay) for your application of interest to see some ideas.<br>Improvements<br>This RTL SDR unit has several imp<br>rovements over generic and other brands including:<br>R820T2 tuner<br>Improved passive component tolerances<br>A 1 PPM temperature compensated oscillator (TCXO)<br>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)<br>SMA F connector<br>Aluminium shielded case with thermal pad for passive cooling to improve L-Band performance<br>Software activatable 4.5v bias tee circuit<br>Improved PCB design for lower noise and less spurs<br>A USB noise choke, more bypass capacitors, and built in ferrites for less PC noise<br>Improved ESD protection (additional ESD diode and extra ESD discharge paths)<br>An improved front end circuit designed for wideband use (other models still use a circuit designed for DVB-T only)<br>Several breakout pads on the PCB for advanced users<br>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.<br>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.<br>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.<br>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, please Google for the RTL-SDR Blog Quickstart guide (links are not allowed on eBay sorry).<br>Shipping&
