Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
The IC-7300 was announced to the public at the Japan Ham Fair in 2015. [2] The radio has 100 watts output on CW , SSB , and FM modulations and 25 watts of output in AM . [ 3 ] Although not the first software-defined radio on the market, the IC-7300 was the first mass-produced mainstream amateur radio to use SDR technology instead of the older ...

HackRF One is a wide band software defined radio (SDR) half-duplex transceiver created and manufactured by Great Scott Gadgets. It is able to send and receive signals. Its principal designer, Michael Ossmann, launched a successful Kickstarter campaign in 2014 with a first run of the project called HackRF. [1]
The board schematics for select USRP models are freely available for download; all USRP products are controlled with the open source UHD driver, which is free and open source software. [2] USRPs are commonly used with the GNU Radio software suite to create complex software-defined radio systems.
On entering World War II in June 1940, the Italians were using book codes for most of their military messages. The exception was the Italian Navy , which after the Battle of Cape Matapan started using the C-38 version of the Boris Hagelin rotor-based cipher machine , particularly to route their navy and merchant marine convoys to the conflict ...
