Parkland High School student Victor Cai has presented work on a proof-of-concept short-range RADAR system, built around a LimeSDR Mini, at the GNU Radio Conference 2020 (GRCon20). Victor’s experimental system, presented with supporting paper during the virtual GRCon20 event, combines an off-the-shelf laptop running GNU Radio with a LimeSDR Mini…

Vilnius Gediminas Technical University student Ugnius Buržinskis has released a video demonstrating a drone hijacking system, designed to prevent unauthorised uncrewed aerial vehicles (UAVs) from entering a restricted area, powered by a LimeSDR Mini. Using the LimeSDR Mini, housed in a protective casing and connected to an off-the-shelf laptop running…

The British Amateur Television Club’s Portsdown digital TV transmitter project now supports the LimeSDR USB open software-defined radio, in addition to its earlier compatibility with the smaller LimeSDR Mini and all-in-one LimeNET Micro. Detailed over on the Lime Micro Community Hub, the Portsdown project offers radio amateurs an easy…

Community member Luigi Cruz has written up how he modified a LimeNET Micro to take part in the Galmon global navigation satellite system (GNSS) monitoring network. “In this blog post, I will explain how I managed to get a GNSS multi-constellation monitor called Galmon working on my LimeNET Micro,” Luigi…

LimeSDR Mini and LimeSDR USB owners seeking additional cooling should take a look at the Hacker Gadgets Lime Active Cooling (AC) Case, heading to Crowd Supply next month. Designed to provide both a protective enclosure and active, rather than the more usual passive, cooling, the Hacker Gadgets Lime AC Case…

The LimeRFE crowdfunding campaign has a new, lower-cost option: the same programmable software-defined front-end board but without the components needed to operate in cellular bands, as an alternative for radio amateurs. “We’ve had some enquiries as to whether it would be possible to make a reduced cost version of LimeRFE…

Community member Kiril Miloshev has been interviewed for the Lime Micro Community Hub, on his experiments with Weak Signal Propagation Reporting (WSPR) using the LimeSDR Mini. “Software defined radios got my attention as they are very universal, and you can do whatever you can imagine with them. Especially ones like…

The second AMSAT-F Recontre Radiomateur Spatiale was a special one, for an out-of-this-world reason: its lectures were transmitted to a global audience using a LimeSDR Mini and the Es’hail-2 (QO-100) satellite.
