USB Problems

If the radio starts but then stops after a few seconds then you probably have insufficient USB power available. Try another USB port or a powered USB hub. You can also use an external power supply provided it meets the manufacturer's specification.



Drivers must be installed, see: https://wiki.myriadrf.org/LimeSDR for latest information.

Source Code

The source code is on GitHub here.

The main header file is here.

The project needed is LimeSuite, the other projects can be and should be ignored.

The first phase is now finished - the LimeSDR is working superbly at bandwidths up to 50MHz and even more.

The Lime developers are now enhancing the LimeSuite.dll even futher.

  • LimeSDR is now in all future kits.
  • Marty Wittrock, KN0CK has been using the code as have Lime software people
  • Possible transmit support in 2016, failing that 2017.

Here's a screenshot...

This is a very early preview of the support for LimeSDRs.


Extensive diagnostic information is available in the logfile and also available in real-time by using DebugView.


  • Maximum bandwidth is 15MHz with USB2 and 80MHz using USB3. Check you are using USB3 but looking at the logfile. The address string contains with USB 2.0 or USB 3.0.
  • To display the FFT (waterfall, spectrum) for high bandwidths you must use a NVIDIA GPU with CUDA support, for example the GTX 950 or a card with similar or better performance.
  • Instead of using the Normalised Gain option the three individual gain options are enabled: LNA, TIA and PGA.
