Boasting a field-programmable gate array with nearly three times the capacity of the original LimeSDR Mini, the upcoming LimeSDR Mini 2.0 will enable increased flexibility and experimentation with new and exciting on-device capabilities.

LimeSDR Mini has proved particularly popular with digital amateur television (DATV) operators and is at the heart of the BATC Portsdown transmitter — a turnkey solution that makes DVB communication readily available to a wide community of radio amateurs — which is frequently used with QO-100, the world’s…

"Whether you’re a Ham radio operator, a network engineer, a mobile base station designer, a security auditor, or some other variety of SDR enthusiast," Yian IT says, "RadioSlate lets you do your thing, even if that thing requires you to go outside and walk around, get unusually close to transmitters and receivers, keep one hand free for other tasks, or manage all of the above without drawing undue attention to yourself."

Demonstration of a bachelor thesis project is given where a LimeSDR Mini is used in a system designed to prevent UAVs from entering an unauthorised area.

"Kimera can capture any camera connected to your computer," Cruz explains, "hardware encode it with any codec available (e.g. HEVC, AVC, AV1), and transmit over TCP, UNIX Socket, or this GNU Radio Transport Layer."

"The ME1130 training kit is a versatile system that can be configured to work as an offline system for simulation or as a real-time system for over-the-air transmission and testing," says DreamCatcher of the training kit, which features a LimeSDR USB and LimeSDR Mini for base station and spectrum analysis operations.

GPUs are increasingly being used in applications outside of graphics and have been popular for some time in both high performance computing (HPC) and machine learning. Thanks to technologies such as the CUDA parallel computing platform from NVIDIA and the Numba high performance Python compiler, the barriers to using GPUs are being lowered all the time, enabling their blistering performance to be harnessed in ever more compute-intensive applications.

The SDR Makerspace is a joint initiative of the European Space Agency (ESA) and Libre Space Foundation, in collaboration with the University of Applied Sciences and Arts Western Switzerland. It brings together makers, open source hackers, radio amateurs and researchers, to tackle the challenges in using…

"The main idea for my narrowband transponder solution," Estevez explains, "is that the BeagleBone Black will just run some software which controls the LimeSDR Mini and streams IQ samples using Ethernet to and from another computer where all the heavy duty work is done."

Users of Lime Microsystems technologies, including the LimeSDR and LimeNET families, are invited to submit brief summaries of their projects and experimentations to highlight the breadth and diversity of the community in Lime's first Field Report Contest.
