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".

Tunes from 500 kHz to 1.7 GHz with up to 3.2 MHz of instantaneous bandwidth<br>(2.4 MHz max stable, 3.2 MHz if your application is tolerant to USB drops)<br>. (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>The Dipole antenna kit is perfect for helping beginners get great reception. The short antennas are great for ADS-B, and the longer antennas work well at the lower frequencies. When used in a V-Dipole configuration the antenna is an excellent option for 137 MHz satellites such as NOAA/Meteor M2 weather and the ISS. In the vertical configuration it is great for terrestrial signals. The two mounts allow you to easily mount the antenna outdoors for best reception. Please note that you should not use the antenna permanently outdoors or during bad weather. It is designed for portable temporary outdoor use. F<br>or using custom antennas note that this dongle has an SMA F connector (not RP-SMA).<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
