AREG’s Project Horus Uses a LimeSDR Mini to Beam Live Video from the Edge of Space

High-altitude ballooning effort Project Horus, a project launched in 2010 by the Amateur Radio Experimenters Group (AREG) of Adelaide, South Australia, has achieve the milestone of transmitting live digital video from the edge of space – using a Lime Microsystems LMS7002M-powered LimeSDR Mini software-defined radio. “Horus 55 was the culmination…

Digital Voice Transmission via QO-100 with FreeDV Mode 2020

"Just try it," urges Gerhard Burian, who has been experimenting with FreeDV 2020 in partnership with David Rowe and Steve Sampson. "It is amazingly easy to set up a simple satellite station. Just get a LimeSDR Mini, the free SDR-Console software, a small Chinese preamplifier, and 10W power amplifier."

QO-100 Communications with the LimeSDR Family

Launched in November 2018, Es'hail-2 - QO-100 - is the world's first geostationary satellite for amateur use, and the LimeSDR community has been making full use of it for everything from stabilisation experiments to live TV broadcasting since it entered into active use.

Weak Signal Propagation Reporting (WSPR) with the LimeSDR Mini

"I attached a cheap 1W high-frequency (HF) amplifier to the LimeSDR Mini," explains system administrator and amateur radio enthusiast Kiril Miloshev, "and with its help I was able to reach Japan, the US, Iceland, the Canary Islands and lots of Europe countries from my home in eastern Europe."

AMSAT-F Rencontre Spatiale Transmission and Reception via QO-100

"I would encourage anyone to give this a try," says Daniel Estévez. "If you already have a LimeSDR or a similar SDR supporting large bandwidths, you already have the most expensive piece of equipment. The rest is standard equipment for satellite TV and it is really inexpensive."

Osmocom-Analog Cellular Base Station Project

The creation of Andreas Eversberg, Osmocom-Analog - built out of a sense of nostalgia, he explains - allows vintage analogue cellular hardware to live again, connecting to a LimeSDR or LimeSDR Mini equipped PC-based base station.

Ultra-Low Cost LimeSDR-Based NMR Spectrometer

"I find the ability to modify and look at the source code to be really valuable," explains Carl Michal of his experiments with the LimeSDR in NMR spectroscopy. "I've learned a lot from tinkering with the LimeSDR that I'm sure I wouldn't have with a proprietary system."

LimeSDR Mini FPGA-Accelerated Real-Time Spectrogram

"I plan to implement the spectrogram accelerator on a LimeNET Micro and distribute it via LimeNET Store," says developer Gaspar Karm of his effort to implement a hardware-accelerated spectrogram on the LimeSDR family's field-programmable gate array (FPGA) chip.

Electromagnetic Field GSM Network

What do you get if you combine the Raspberry Pi with the LimeSDR Mini? If you're Sam Machin, Andrew Back, and colleagues, you get 16 rapidly-deployable GSM base stations for use at Electromagnetic Field 2018, a three-day event held in the middle of a field every two years.

MarconISSta

A project which has seen an LMS7002M-based LimeSDR software defined radio installed on the International Space Station to map and monitor global radio frequency spectrum usage, MarconISSta is already showing interesting results from its early data.

Open Satellite Project

"The final goal is to have a generic satellite receiver that is easy to configure to a new satellite or protocol," project originator Lucas Teske explains of the Open Satellite Project and its open-source weather satellite software.

Raspberry Pi DVB Transmitter

Evariste Coujard's experimentation with a UNIX-like "KISS" DVB transmission pipeline formed the basis for a self-contained, battery-powered Raspberry Pi and LimeSDR Mini based DVB transmission system.
