OTA: QO-100 Field Report, DAB via ODR-mmBTools, the RadioInstigator, and More

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…

OTA: LimeSDR WSPR, Angle of Arrival Experiments, DSPs without Maths, and More

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…

OTA: LimeSNA, QO-100 Projects, a Self-Tuning Antenna, and More

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…

OTA: Es’hail 2’s Amateur Transponder, Cellular Satcom, Magma, and More

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…

OTA: PiTop SDR Upgrade, Osmocom, srsLTE Updates, and More

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.

OTA: LimeSCAN Demo, GRCon18 Videos, Google Assistant via Ham, and More

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…

OTA: SatNOGS Dashboard, Tempest Tutorial, Es’Hail 2 Update, and More

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…
