GNU Radio is a free software development toolkit that provides signal processing blocks to implement software-defined radios and signal processing systems. It can be used with external radio frequency (RF) hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic ...
As of WSJT10, supported fast modes are JTMS, FSK441, ISCAT, and JT6M, and the slow modes are JT65 and JT4. [2] WSJT-X 1.8 additionally implements the "slow" JT9, FT8, and QRA64. Some modes have derived submodes with larger tone spacing. [2] Two other modes, WSPR and Echo are included for measuring propagation and testing moon bounce echo. [2]
Universal Software Radio Peripheral (USRP) is a range of software-defined radios designed and sold by Ettus Research and its parent company, National Instruments. Developed by a team led by Matt Ettus , the USRP product family is commonly used by research labs, universities, and hobbyists.
The first radio software for automation, using lossy compressed digital audio codecs, was named Audicom and was internationally introduced at the 1990 National Association of Broadcasters Convention in Atlanta, USA. [2] The world's first radio station to use it was one in San Francisco, California.
RA was the first BBS software to support the popular JAM Message Base Format, which was partly conceived by RA's author, Andrew Milner. RA was also the first shareware BBS software to support a FDB (file database), rather than using files.bbs text files to describe files in each directory.
Single operator two radios (SO2R) is an operating practice employed by some competitors in the sport of amateur radio contesting.By using two transceivers attached to separate antennas, competitors can listen to one amateur radio band while transmitting on another.
