Testing the Lime mini SDR
« on: December 20, 2018, 09:33:08 am »
Here is the details on how to test the Lime mini SDR

This repository will have all my Lime mini configurations.
Installing soapysdr on ubuntu 18.10

sudo apt-get install python3-pip python3-pyqt5 python3-numpy python3-scipy soapysdr python3-soapysdr #packages for soapysdr available at myriadrf PPA
cd /usr/share/doc/soapysdr-tools/ sudo add-apt-repository -y ppa:myriadrf/drivers
sudo apt-get update
sudo apt-get install limesuite liblimesuite-dev limesuite-udev limesuite-images
sudo apt-get install soapysdr-tools soapysdr-module-lms7
sudo apt-get install soapysdr
LimeUtil --info

Testing the transmitter in Gnuradio.

Link to block source
Here is a Gnuradio block that will modulate the Lime mini sdr with Fm from Microphone and 1 Khz zone.
In the gnuradio radio directory is a working Transmitter testing code.

Here is the settings for the Lime mini. (you need to install the soapySDR drivers.

Screenshot of Application
Changing the PTT value to 1 enables modelation.
Changing the enable tone to value 1 will switch the modelation from internal Microphone of laptop to the 1Khz tone generator.
The Modulation can be seen in the FFT Plot box.
