Yes, for some student and hobby experiments we need cheaper SDR. I like the idea of OpenSource-Hardware. Material cost is usually not too high. And it's possible to modify designs, improve it, strip down for cheaper variants ... A good toy for hardware-experimenting and to gain experience in electronics design. Some people are even more interested in the hardware designs than in SDR software. So, EDA files, schematics, ... The best for educational purpose is to have it all OpenSource.
There are several OpenSource/OpenHardware SDR-Projects: FreeSRP http://freesrp.org/ http://electronics.kitchen/misc/freesrp/ HackRF http://greatscottgadgets.com/hackrf/ https://github.com/mossmann/hackrf LimeSDR/-mini https://wiki.myriadrf.org/LimeSDR-USB https://github.com/myriadrf/LimeSDR-Mini Kiwi SDR http://kiwisdr.com/kiwisdr/ http://kicad-pcb.org/made-with-kicad/kiwisdr/ some other projects https://github.com/myriadrf A64-OLinuXino, similar to Raspberry https://github.com/OLIMEX/OLINUXINO There's also a free OpenSource EDA Tool KiCad. It lacks several features, but you can use it even for bigger projects: http://kicad-pcb.org/made-with-kicad/ Am 29.09.2017 um 10:18 schrieb w xd:
Hello guys, Have some suggestion on the cheaper SDR platform for us to use with the GNURADIO software? As a student, I cannot buy the expensive usrp ,but I want to learn the knowledge by the hardware and software. Any recommend? For example,use the hardware to do some experiments about LTE/WIFI.
