RTL-SDR Blog V4L (Lite) RTL2832U 1PPM TCXO HF BiasT SMA Software Defined Radio For Sale

Important Note on Avoiding RTL-SDR SCAMS:Note that theprofile"rtl-sdr-blog"is the official eBay account for RTL-SDR Blog.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 Blog products. Most of these scammers have no intention of posting anything out, and will simply take your money and run.
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 RTL-SDR Blog V4L R828S RTL2832U 1PPM TCXO HF Bias Tee SMA DongleNote that no antennas are included in this listing. Please see our other listings for a listing that includes an antenna kit.
P​lease note, this is the new V4L (Lite) unit and not all software is compatible with it yet! Compatibility with most programs on Windows and Linux is OK, but MacOS and Android is still catching up. Please consult the V4L users guide on our website for more information (sorry eBay does not allow links, but the link is in the included instruction booklet).
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, METEOR M2 and GOES 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:

• R828S tuner
• Improved passive component tolerances
• A 1 PPM temperature compensated oscillator (TCXO)
• HF mode via built in upconverter
• 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)
• Several breakout pads on the PCB for advanced users

This is an RTL-SDR Blog V4L (Lite) software defined radio receiver with RTL2832U ADC chip, R828Stuner, 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). 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 R828Stuner, 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 a built in upconverter, and allows for tuning down to 500 kHz. There is a built in 28.8 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). Installation on Windows is simple, please Google for the RTL-SDR Blog Quickstart guide (links are not allowed on eBay sorry).
