Next generation software-defined radio (SDR) driver stack brings numerous improvements.

New release of Lime Suite includes numerous improvements, along with support for the LimeRFE RF front-end, plus packaging for Ubuntu 20.04.

New release planned for the end of July and in the meantime it's recommended to build from Lime Suite master branch.

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…

Welcome to the eighth instalment of the LimeSDR Made Simple series. Very early on in episode 1, we promised to work from SDR novice to API programming examples in small, bite sized chunks. Having done many of those steps it’s now time to take the final one and start programming.

Back in June, during the LimeSDR crowdfunding campaign, one of the many great demos that we shared details of was a basic Vector Network Analyser (VNA). Since then we’ve understandably had quite a few requests to share the code and this was always the intention...

LuaRadio is a lightweight, embeddable flow graph signal processing framework for SDR and as the name suggests, it is written in the Lua language. It benefits from no external hard dependencies and a binary footprint of an impressively small

The crowdfunding campaign may have drawn to a close — and what a fantastic result! — but work continues in the core engineering team in order to get full scale production and testing in place, and also in the community of beta testers which have early access to LimeSDR hardware.

LoRa is a chirp-based modulation format that can operate beneath the noise floor. Its robust, low power, and low rate -- and a candidate technology for connecting the internet of things. In this blog I will cover the basics of LoRa modulation, show off the LoRa PHY blocks for Pothos, and demonstrate simple relay and client applications using a pair of LimeSDRs.

One of the reasons why I find the LimeSDR interesting is that it can transmit high data rates over a wide frequency spectrum. It covers many ham radio bands where we can legally transmit wide signals using high power. This allows us to experiment cutting edge technologies such as digital video transmission over the air.

When the new Lime SDR arrives at your doorstep, you will find that its immediately usable within a variety of existing SDR applications and software stacks.

My LimeSDR board arrived on April 26, a day before the crowdfunding campaign was launched. I made an agreement to test the board and post my experiences here on the MyriadRF blog. This is the first out of hopefully many posts I will make about the LimeSDR.
