GNUradio - VK1DJA - 26-02-2023
An interesting software package for homebrewers is Gnuradio. Freeware, runs best under Linux. It is an extensive collection of DSP modules together with a software generator Gnuradio Companion). GRC takes a schematic of a DSP chain and generates an executable program.
It pairs well with the transceivers on a board, like the LimeSDR, the Hack RF One, the Pluto and the Ettus B20x. These are IQ devices and need the DSP to make an operational transceiver.
My experience in building a couple of transceivers with an Ettus B200mini confirms that GR is versatile and powerful. It's documentation is not the best but is improving. Some knowledge of DSP basics is needed. DSP is one of those topics that moves from mysterious to straightforward as you fall into the mindset.
There is a wealth of material on the Web. Be aware that many reports on amateur radio projects are not strictly correct.
