Some LimeSDR Demonstration Videos
Recently Michael DG0OPK wrote in and wanted to share some videos of the LimeSDR in action that he’s uploaded to YouTube. The first video shows LimeSDR running with the SDRangel software and receiving the 950 MHz mobile phone band. SDRangel appears to be GPU accelerated so the waterfall can show a lot of detail very quickly.
The second video shows the LimeSDR transmitting DVB-S/S2 on and ODROID XU4, and the signal being received on a PC using and Airspy, and being watched live with a standard DVB-S2 TV Card. The Odroid XU4 is a single board computer like the Raspberry Pi but much more powerful.
On his channel Michael also has some other LimeSDR videos that you can check out such as testing the LimeSDR with GNURadio on the 23cm band for full duplex DVB-S2, and running the LimeSDR at full speed 60fps, 50 MHz on a i7 PC.
The LimeSDR is a full duplex RX/TX capable SDR with a 100 kHz – 3.8 GHz frequency range, 12-bit ADC and up to 80 MHz of bandwidth. A unit currently a unit currently costs $289 USD on Crowd Supply.
The SDRAngel project is very exciting. Progress has been made recently toward enabling transmit. I haven’t installed yet but there is a user group on Facebook that is very pumped about this.
