November 18th, 2018: The Lime options are now shown in the Receive DSP panel instead of the ribbon bar.
The options are:
At the bottom you see the chip temperature, TX drive level and TX peak input since the last update (usually one update per second).
Selecting More opens the advanced options display.
The Antennas window shows the frequency range assigned to the antennas by the Lime support library, this information does not reflect any hardware changes.
Displays the hardware clocks, enables external reference options.
Optionally save the settings file when the Lime SDR is closed, this is for development use only and will be removed in a future release.
Enable the analog and digital filters, by default these are enabled (recommended).
Primarilly for development use, ths enables the level of diagnostic information returned by the Lime support library.
To reduce the spur seen in the centre of the display there are two options: Firmware and Software. The software option is usally better than firmware. Gain and Phase correction are usually enabled.
These options are usually enabled.
Disable the transmitter while in receive. Even when not sending and data the transmitter is till active unless disabled, so it is advisable to disable the transmitter while in receive.
Used for debelopment / test purposes, specify a .ini file with pre-defined values. These .ini files are usually created with the limeSuite GUI.
November 12th, 2018: Initial transmit support for:
Initially only half-duplex is supported using RX1 and TX1. Later full duplex will be supported using RX1 / TX2 with the Lime USB (the Lime Mini only supports RX1 and TX1).
Use an external pwer supply (PSU) with the Lime when transmitting, recommended voltage is 8v, more than this is just dissipated as heat.
To calibrate the transmitter select TX Calib., this will reduce the spur in the centre of the transmission. Currently the transmitter is not automatically calibrated. Some users are reporting improved calibration (spur reduction) when the unit is properly cooled.
Full transmit support information is here [link].
See: driver installation for latest information.
Now follow the instructions on driver installation
Make sure you are using the latest firmware, information is on the wiki: [Link].
If the radio starts but then stops after a few seconds or runs slowly 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.
May 6th, 2018: Working reliably with bandwidths up to 20Mhz. Above 25MHz the quality is poor, this is being investigated.
November 22nd, 2017: The LimeSDR Mini works.
The LimeSuiteGUI is downloaded here. Use this program up load new firmware, very simple process.
Firmware info is here.
The Lime support library 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.
