Gqrx Receives Amateur Radio and Weather Satellites

In a previous update we introduced the LimeSDR driver architecture and a blog post that Josh Blum had put together on this and its various components, including the APIs that give us plug-and-play compatibility with a vast array of existing SDR ecosystem software.

In a new post up on the Myriad-RF blog, Alexandru Csete takes us through his first experiences with LimeSDR and getting it to work with the popular SDR receiver application, Gqrx. Noting how, thanks to Josh’s work on the driver, this was simply a matter of configuring appropriate sample rate and bandwidth settings.

With this simple configuration out of the way, Alex was quickly able to verify operation by receiving FM radio stations, before then going on to receive signals from an amateur radio satellite some few thousand kilometres away. Following which he succeeded in receiving data from an NOAA weather satellite and extracting near infra-red and thermal infra-red images from this.

We’re sure you will agree, that this is a very cool demo indeed, demonstrating the power of the open source ecosystem and hinting at just some of the great many potential applications for LimeSDR.

Thanks for sharing your initial LimeSDR experiences with us, Alex!

$299

LimeSDR

The LimeSDR is based on Lime Microsystem’s latest generation of field programmable RF transceiver technology, combined with FPGA and microcontroller chipsets. These connect to a computer via USB3. LimeSDR then delivers the wireless data and the CPU provides the computing power required to process the incoming signals, and to generate the data to be transmitted by the LimeSDR to all other devices.


$99

Acrylic Case

A layered acrylic case to protect your LimeSDR. Can be used with either USB Type A or micro USB Type B. Antenna not included - separate purchase available.


$599

LimeSDR with Aluminum Kit

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. This board comes with fancy aluminum casing. The board will be delivered with turnkey support for a diverse range of SDR ecosystem software, a powerful API and rapid prototyping environment. All the boards in this category will come with a fancy Aluminum casing coated with high quality material, cables, and antennas for a quick set up.


$799

Ultimate LimeSDR With PCIe Interface

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. The board will be delivered with turnkey support for a diverse range of SDR ecosystem software, a powerful API and rapid prototyping environment. All the boards in this category will come with a PCIe interface, cables and Antennas for a quick set up.


$85

Four Antenna + Cable Pairs

Omni-directional antenna set, covering frequency ranges 800-960 MHz, 1710-2170 MHz, and 2400-2700 MHz. Includes U.FL to SMA cables.


$169

GPIO Board

This stackable expansion board for the LimeSDR provides individually settable, bi-directional level-shifted I/O for FPGA GPIO 0-7. Each I/O has a high-voltage and power Darlington drive stage suitable for inductive loads, such as coaxial relays. LimeSDR not included.


$79

Hacker Case

This custom acrylic case accommodates both a LimeSDR and a GPIO Board, and includes SMA connectors for all RF ports, two SMA connectors for clock I/O, and a 40 mm cooling fan. LimeSDR and GPIO Board not included.
