Rtl sdr

This project talks about how RTL-Software Defined Radio dongles can easily perform the function of an SDR receiver using an Android smartphone.

Over on Imgur and Reddit user Mavericknos has uploaded a very nice pictorial guide where he shows how he's built a high performance RTL-SDR based ADS-B receiver that can be mounted outside in a waterproof enclosure. He uses a FlightAware dongle, which is an RTL-SDR optimized for best ADS-B reception when placed directly at the mast/antenna. For an antenna he uses the FlightAware ADS-B antenna, which we've reviewed in the past and found to be one of the best value ADS-B antennas available on…

Notes on the construction and operation of a multi-op Amateur Radio Station

Recently we found this post from last year by security researcher Anthony which shows how an RTL-SDR combined with an Arduino and CC1101 transceiver can be used to open a car. The technique he presents is the jam, intercept and replay technique which was also used by Samy Kamkars Rolljam device. Most modern vehicles use some form of rolling code security on their wireless keyfobs to prevent unauthorized replay attacks. When the car owner presses a button on the keyfob, a unique rolling code…

Over on YouTube user Fuzz has uploaded a video showing his solar powered NOAA weather satellite receiver. The system is based on a Raspberry Pi connected to an RTL-SDR.com dongle. The front-end input of the RTL-SDR dongle consists of an LNA and FM reject filter, and this is all connected up to a QFH antenna in his front yard. The electronics are completely solar powered, with the solar system consisting of solar panel, solar controller and four 12v batteries used for energy storage. A 12V to…

Over on Twitter and his github.io page, Pieter Noordhuis (@pnoordhuis) has shared details about his low cost RTL-SDR based GOES satellite receiving setup. GOES 15/16/17 are geosynchronous weather satellites that beam back high resolution weather images and data. In particular they send beautiful high resolution 'full disk' images which show one side of the entire earth. As the satellites are in geosynchronous orbit, they are quite a bit further away from the earth. So compared to the more…
