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]

WSPR (pronounced "whisper") is an acronym for Weak Signal Propagation Reporter.It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators.

It is built around a modular concept which encourages experimentation with new techniques and devices (e.g. SDR, Envelope Elimination and Restoration) without the need to replace the entire set of boards. The project has expanded from the original group, and several additional people have been involved in recent HPSDR module designs.
The SCA is published by the Joint Tactical Networking Center (JTNC). This architecture was developed to assist in the development of Software Defined Radio (SDR) communication systems, capturing the benefits of recent technology advances which are expected to greatly enhance interoperability of communication systems and reduce development and deployment costs.
Additionally, gateways operating on the U.S. trust server are asked during initial setup to install DStarMonitor which is an add-on tool that allows the overall system administrators to see the status of each Gateway's local clock and other processes and PIDs needed for normal system operation, and also sends traffic and other data to servers ...
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]
