The 35th Chaos Communication Congress (35c3) played host to antenna engineer Friederike Maier, whose talk on software defined radio basics and modulation theory serves as a great introduction to the concepts for beginners. “Encoding or decoding random radio-waveforms doesn’t need incredible expensive hardware any more, which offers new possibilities for…

The board design files for the LimeNET Micro v2.0, which includes expanded bandwidth for the radio portion as well as making more features of the Raspberry Pi Compute Module 3 available, have now been published to the Myriad-RF GitHub repository. First announced back in October, the LimeNET Micro v2.0…

Popular software package SDR-Console is set to get transmit support on the LimeSDR range, from version 3.0.4 onwards – once beta testing is complete. The new feature of SDR-Console v3.0.4 was teased by Jason Fairfax on Twitter late last month. “Calling CQ SSB on 144.300 MHz from IO81rk,” he…

The LimeNET Micro has received a few upgrades since its crowdfunding campaign, now in its last two weeks, launched, including considerably improved RF bandwidth, active Power-over-Ethernet (PoE), and both DSI and HDMI display connectivity. Designed to meld the LimeSDR with the Raspberry Pi Compute Module 3 to create a fully-standalone…

The LimeNET Micro crowdfunding campaign continues, and has brought with it a welcome change to the design which will greatly increase the radio’s available bandwidth and sample rate while also adding support for camera and display accessories. Announced via a crowdfunding campaign late last month, the LimeNET Micro is the…

GNU Radio Foundation president Ben Hilburn has launched a questionnaire to gauge interest in a UK event for GNU Radio users and developers, tentatively titled the GNU Radio Symposium, which would run along with the existing European GNU Radio Days and GNU Radio Conference events. Originally developed by Eric Blossom…

Lime Microsystems has launched a crowdfunding campaign for the LimeNET Micro, an all-in-one device which combines the LMS7002M field-programmable radio frequency (FPRF) chip with a Raspberry Pi Compute Module 3, bringing the LimeNET family to its lowest price point yet. Designed with narrowband applications in mind, the LimeNET Micro operates…

The team from Lime Microsystems will be at the Telecom Infra Project (TIP) Summit in London next week, with a range of LimeNET and CrowdCell demonstrations. Part of the cross-vendor Telecom Infra Project (TIP), founded to encourage openness and disaggregation in access, backhaul, and core & management of a modern…

While most users of the LimeSDR focus on its LMS7002M radio frequency integrated circuit (RFIC), naturally enough, there’s flexibility to be found also in its field-programmable gate array (FPGA) – as proven by Gaspar Karm’s project to add a DC-removal filter into the board’s gateware. As the name suggests, a…

Vodafone and Lime Microsystems have announced the first in a planned series of annual hackathon events designed to benefit the Telecom Infra Project, focused on developing on top of the LimeSDR powered CrowdCell platform. A part of the Telecom Infra Project, which aims to drive innovation in the telecommunications arena…

LimeSDR units will be a key feature of this year’s Electromagnetic Field (EMF Camp) event, taking place in the UK this weekend, powering a local GSM cellular network for attendees’ use. Part camping festival, part gigantic temporary hackspace, Electromagnetic Field is this year held in Eastnor, UK, and on…

Satellite communications specialist Planet Labs has announced its entry into the open-source radio community, with an open-hardware device dubbed the OpenLST built exclusively using widely-available commercial off-the-shelf (COTS) parts. “Radio system design is often viewed as a ‘black box’ that is out of reach to all but the most experienced…
