MyriadRF has stretched to the stars this week with the official launch of the SDR Satcom initiative, a collaboration between Lime Microsystems and the European Space Agency (ESA) Designed to help lower the barrier to entry in the satellite communications industry, SDR Satcom combines the low-cost high-performance LimeSDR Mini software…

The LimeRFE crowdfunding campaign has a new, lower-cost option: the same programmable software-defined front-end board but without the components needed to operate in cellular bands, as an alternative for radio amateurs. “We’ve had some enquiries as to whether it would be possible to make a reduced cost version of LimeRFE…

Schematics for the LimeRFE software-definable front-end module for LimeSDR and LimeNET devices have been released, as part of Lime Microsystems’ pledge that it will be fully open hardware. “We’ve had a number of requests to share the LimeRFE schematic diagrams, and we’re pleased to report that they are now available…

The crowdfunding campaign for the LimeRFE, a software-definable front-end module designed for use with LimeSDR hardware, has blown past its funding goal – with over a month left on the clock. Designed to be used with LimeSDR and LimeNET hardware, the LimeRFE is an open-hardware design with open-source software and…

The first of the LimeSDR Field Reports has been published, courtesy of community member Daniel Estévez: a look at his LimeSDR Mini-powered satellite ground station project. “My project uses a LimeSDR Mini as the basis for a ground-station for the amateur radio transponders on the geostationary satellite ‘Es’hail 2’ (known…

Community member Kiril Miloshev has been interviewed for the Lime Micro Community Hub, on his experiments with Weak Signal Propagation Reporting (WSPR) using the LimeSDR Mini. “Software defined radios got my attention as they are very universal, and you can do whatever you can imagine with them. Especially ones like…

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…
