"It is difficult for open source practices to thrive in the chip-design industry," the board's designers say, "but Maverick-603 demonstrates that open source chip design can produce products that equal or surpass their closed-source counterparts."

Using a home-made downconverter, a 2.4m prime-focus satellite dish, and the open-hardware LimeSDR USB software-defined radio - powered by Lime Micro's LMS7002M - Viehweger has been able to capture and decode imagery from the satellite's X-band downlink.

Latest enhancements to Portsdown, from British Amateur Television Club (BATC) chair Dave Crump (G8GKQ), offer an enhanced signal generator and a new band viewer - both fully compatible with the LimeSDR Mini.

"Bring your own network functions to the upcoming VNF onboarding hackfest," product manager Wajeeha Hamid writes, "to have hands-on experience of onboarding under the full-week supervision from OSM experts."

"This proof of concept opens the doors to many short-range RADAR applications using the emerging low power and low cost SDR technology," says student Victor Cai of his experimental software-defined radio project built around a LimeSDR Mini and GNU Radio.

"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."

LiFi or light fidelity is similar to WiFi and as the name suggests, instead of using radio waves, utilises visible, IR or UV light for communications. The new development kit from Hyperion Technologies is based upon the LimeSDR USB and uses two of these together with optical transmitter and…

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.
