2. Software-defined radio - Wikipedia

   en.wikipedia.org/wiki/Software-defined_radio

   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]

4. Universal Software Radio Peripheral - Wikipedia

   en.wikipedia.org/wiki/Universal_Software_Radio...

   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.

5. ICOM IC-7300 - Wikipedia

   en.wikipedia.org/wiki/ICOM_IC-7300

   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 PLL-based transceiver design. [4] Designed to replace the older IC-746PRO the IC-7300 is smaller and significantly lighter than its predecessor. [5]

6. Transceiver - Wikipedia

   en.wikipedia.org/wiki/Transceiver

   Despite being able to transmit and receive data, the whole unit is colloquially referred to as a "receiver". On a mobile telephone or other radiotelephone, the entire unit is a transceiver for both audio and radio. A cordless telephone uses an audio and radio transceiver for the handset, and a radio transceiver for the base station.

7. QSK operation (full break-in) - Wikipedia

   en.wikipedia.org/wiki/QSK_operation_(full_break-in)

   Of particular note is that many of the modern so-called software defined radio (SDR) transceivers have particularly slow AGC functions because of the latency created by the extensive digital signal processing (A/D conversion, D/A conversion, digital filtering, digital modulation and digital demodulation) used for the SDR implementation. For ...

8. Software Communications Architecture - Wikipedia

   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.

9. M17 (amateur radio) - Wikipedia

   en.wikipedia.org/wiki/M17_(amateur_radio)

   With a small hardware modification, TYT MD-380, MD-390 and MD-UV380 handheld transceivers can be flashed with a custom, free, open source firmware [12] to enable M17 support. In July 2024, a US-based company Connect Systems, Inc. released the CS7000-M17, being the first commercial off-the-shelf handheld transceiver with native M17 support. [13]
