A micro version of the classic RTL SDR Dongle - Perfect for your Raspberry Pi SDR server or when you've got a populated "back of PC". Covering from 25MHz to around 1800MHz, it allows reception of AM, CW, FM, SSB for Amateur Radio as well as airband, broadcast radio and other frequencies (incl plane-radar/tracking). Subject to computer power, your waterfall can span over 2.5MHz. A small magmount aerial is provided but you are advised to use an aerial tuned for the operating frequency - for that, we include the option of a BNC or SO239 adapter as part of the package.
Compatible with software such as HD-SDR and SDR# (now Airspy SDR#) - using the direct sampling driver DLL, you can also tune below 25MHz with SDR#. Read this article for a comparison between this and the original R820T dongle. These also work on the Raspberry Pi - check out this page for details of rolling your own Pi-based SDR receiver! If you're looking at tracking planes, Dave M0TAZ has written a useful blog post on ADS-B reception here.
