Software Defined Radio is a large topic, and will not be covered in depth here. Should the reader be interested in exploring building transceivers in an SDR context, both the BladeRF and HackRF are interesting hardware options to look at. A comprehensive list of SDRs can be found here<ref>https://en.wikipedia.org/wiki/List_of_software-defined_radios</ref>. SDRs are typically interfaced with GNUradio or another software radio programming environment<ref>https://en.wikipedia.org/wiki/GNU_Radio</ref>. Every feature and facet of a modern dedicated hardware transceiver can be implemented in software on a laptop or workstation. | Software Defined Radio is a large topic, and will not be covered in depth here.

An inexpensive option for those wishing to build a quality receiver for their long-range antenna project is RTL-SDR. | An inexpensive option for those wishing to build a quality receiver for their long-range antenna project is working with RTL-SDR devices and compatible tuners. RTL-SDR devices are low-cost digital video tuner (DVB-T) USB sticks using the Realtek RTL2832U controller that can be repurposed for receiving a broad spectrum of radio signal<ref>https://www.rtl-sdr.com/</ref>. The project is maintained by a radio enthusiast group called Osmocom<ref>https://en.wikipedia.org/wiki/Osmocom</ref>. RTL-SDR drivers exist for GNU/Linux, Windows and OS X, and can be tuned with several different popular interfaces. One of them, which is recommended for beginners, is the cross platform visual tuner and de-modulator GQRX<ref>https://gqrx.dk/</ref>. | ||
