Rtl sdr

Akos from the radioforeveryone.com blog (previously sdrformariners/rtlsdrforeveryone) has recently added several new posts. The first new post is a beginners guide to RTL-SDR accessories. In this post he shows and links to his reviews of various RTL-SDR accessory products such as upconverters, baluns, filters, preamps and adapters. In the second post he shows a guide to 5 easy mods that can be performed on RTL-SDR dongles which will improve their performance. The mods include using a ground…

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

An introduction to the cool new SDR radio!

A weekly project log

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…

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…

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…

NOTE: We have found more stock of R828D chips, so the V4 should be in production hopefully until the end of 2025. We're happy to announce the first release of our new RTL-SDR Blog V4 dongle which is based on the R828D tuner chip. The pricing is US$39.95 for the V4 dongle with antenna set, and US$29.95 for the dongle only, including free shipping to most countries. Currently we are only shipping this model from our warehouse in China and the initial production batch is small and so we are…
