LimeSDR is an USB SDR device with full OpenSource software support. It has Lime Microsystems LMS7002M RF-transreceiver and Altera Cyclone IV EP4CE40F23 FPGA on board. It uses SoapySDR hardware abstration library for SDR-software.

Main features:

  • RD frequency range: 100kHz-3.8GHz
  • RF bandwidth: 61.44MHz
  • Sample depth: 12 bits
  • Sample rate: 61.44MSPS
  • Host interface: USB 3.0

Hardware

$ lsusb
Bus 002 Device 087: ID 1d50:6108 OpenMoko, Inc. Myriad-RF LimeSDR

device appears as OpenMoko.

Lime Suite

Device support software is called Lime Suite that provides LimeUtil, LimeQuickTest and graphical LimeSuiteGUI tool.

gqrx

Gqrx support was announced at 2016-05-01 by Alexandru Csete. It needs to be run as root permissions.

Configuration settings for I/O device::

  • Device string: soapy=0,driver=lime
  • manually set sample rate and bandwidth:
    • sample rate:
    • bandwidth:
  • Leave “LNB LO” at 0 unless you actually have an LNB in front of your device.

Sample rates that work: 1.25, 2.5, 5, 10 Msps. Bandwidths: 1.5, 4, 10 MHz Other sample rates will also work For frequencies < 30 MHz, use bandwidth 60 MHz (or 100 ) For frequencies > 30 MHz, we can use 0 meaning auto. Other bandwidth values should also work, but some of them crash.

Errors

  • SoapySDR::Device::make() no match - device permission problems.
  • [ERROR] SetFrequencySXR(30 MHz) - cannot deliver frequency
  • [ERROR] Rx calibration: MCU error 3 (SXR tune failed)
