Since the project was announced last year we’ve suffered a number of setbacks due to circumstances outside of our control. For example, the company we planned to use for customised rack mount enclosures exited the market due to pandemic related issues. However, we are pleased to report that we are now making good progress and a long overdue update follows.

The LimeSDR-powered Portsdown digital TV transmitter project has been featured in the latest issue of The MagPi Magazine, showcasing how low-cost software-defined radio is being used by the British Amateur Television Club (BATC). “Now Dave [Crump, chair of the BATC] has completed Portsdown 4, using the more powerful Raspberry Pi…

The team at Enjoy Digital has been testing out the upcoming LimeSDR Mini 2.0, and has already turned it into a self-contained computer through the porting of the open-source LiteX system-on-chip to the on-board FPGA — using a fully-open toolchain. Announced last month, the LimeSDR Mini 2.0 is designed to…

Lime Microsystems has announced the LimeSDR Mini 2.0, an upgraded version of the smallest member of the LimeSDR range featuring a considerably improved field-programmable gate array (FPGA) – boosting its flexibility. Since its launch in 2017, the LimeSDR Mini – a single-channel full-duplex software defined radio built on the same…

Developer Wayne Campbell has released version 0.5.1 of rsadsb, a Rust-based ADS-B aircraft tracking system with a text-mode user interface — bringing with it its first support for LimeSDR devices. “Release v0.5.0 of rsadsb is now released,” Wayne writes of the launch. “Use any SDR supported by SoapySDR. If any…

Arved Viehweger is among a growing number of LimeSDR users turning their attention to X-Band satellite communications – receiving impressive high-resolution imagery from Russia’s ARKTIKA-M1 satellite. Launched in February 2021 as the first in the ARKTIKA constellation and serving as an Arctic monitoring system, ARKTIKA-M1 transmits at the lower end…

The UK government has announced a target of carrying 35 per cent of all cellular traffic over open radio access networks (open RANs) by 2030, alongside the planned retirement of 2G and 3G cellular – and LimeSDR technology has been selected for two key test-bed projects. “The mobile network operators…

Lime Micro products, including the LimeSDR family, are still being impacted by global component shortages and supply chain disruption – but Lime’s Ebrahim Bushehri has detailed how the company is working to overcome the issues. “While we’ve placed our orders and hope the supply chain settles down soon, we’re not…

Researchers from the University of California at San Diego (UC San Diego) have published a paper highlighting location-tracking attacks against mobile devices which leverage fingerprinting of Bluetooth Low Energy (BLE) physical layer attributes. “Mobile devices increasingly function as wireless tracking beacons. Using the Bluetooth Low Energy (BLE) protocol, mobile devices…

MyriadRF has been highlighted by the European Commission as an exemplar of how open source software and hardware can provide what its report describes as a clear “public good. In a report into the impact of open source software and hardware on the European economy, the European Commission’s Directorate-General for…

Alexandre Rouma’s SDR++ project, a cross-platform open-source package for software defined radio work with built-in support for LimeSDR-family hardware, has hit a milestone: the release of version 1.0.0. “For those who don’t know,” Alexandre explains, “SDR++ is a cross-platform (Windows, Linux, MacOS, BSD) and open-source general purpose receiver software meant…

Lime Microsystems has announced a new version of its LimeSDR-powered LimeNET 5G-capable software-defined radio-network-in-a-box – now featuring a 16-core high-performance AMD Ryzen processor. “We are excited to collaborate with Lime Microsystems and the LimeNET ecosystem,” said AMD’s senior director of applications engineering Kun-Yip Liu of the project, “to enable innovative…
