Community member Godfrey L has published a multi-part series on using a LimeSDR and the ODR-mmbTools software bundle to transmit Digital Audio Broadcasting (DAB) signals. “My journey on the reason to use LimeSDR and ODR-mmbTools for DAB/DAB+ transmission started from the announcement that Raspberry Pi could transmit FM station all…

The LimeSDR family has grown a little larger with the unveiling of the LimeRFE, an open hardware software-definable front-end add on for the LimeSDR, LimeSDR Mini and LimeNET Micro. Due to launch on Crowd Supply in the near future, the LimeRFE includes power amplifier, filter, and support circuitry, is programmable…

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. Evariste Courjaud explained the transmission chain in an interview published this week on the Lime Micro community hub:…

Forum user Peter ‘nepe’ Kis has published a scalar network analyser (SNA), developed using the LimeSDR Mini, which displays its user interface in the user’s web browser: limeSNA. Based on the pyLMS7002Soapy example, Peter’s software has been tested with the LimeSDR Mini and should be compatible – or easily made…

Backers of the LimeNET Micro are set to receive a boost in computing power and storage thanks to a last-minute switch in Raspberry Pi Compute Module model, while shipping has now been pushed to the end of March. “As you all know, there were quite a few changes to the…

The amateur transponder on board the Es’hail-2 satellite, launched back in November, has been activated and qualified as ready for amateur use – and use it amateurs most certainly are. Launched in November 2018 by Qatari communications company Es’hailSat, the Es’hail 2 satellite is located at 25.5 degrees East and…

The MarconISSta mission, which saw a LimeSDR and Raspberry Pi installed on the International Space Station (ISS), has successfully completed its first phase and has been safely deinstalled and stowed. “MarconISSta was deinstalled on Saturday, February 9th 2019, by NASA astronaut Anne McClain,” writes project lead Martin Buscher in what…

A video demonstrating the integration of a LimeSDR Mini with the modular, Raspberry Pi-based PiTop laptop has been released – and all it took was a few laser-cut parts. “The PiTop is a rather cool modular laptop that you build yourself and which is based around the Raspberry Pi platform.

The LimeNET Micro campaign has posted a demonstration of an alpha-status project dubbed LimeSCAN, taking advantage of the ability to run software defined radio and general purpose processing tasks on a single standalone unit to scan for radio spectrum usage data and share it via a private Ethereum blockchain. “The…

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…
