Fldigi (short for Fast light digital) [4] is a free and open-source program which allows an ordinary computer's sound card to be used as a simple two-way data modem.The software is mostly used by amateur radio operators who connect the microphone and headphone connections of an amateur radio SSB or FM transceiver to the computer's headphone and microphone connections, respectively.

As with all software-defined radio systems, reconfigurability is a key feature. Instead of using different radios designed for specific but disparate purposes, a single, general-purpose, radio can be used as the radio front-end, and the signal-processing software (here, GNU Radio), handles the processing specific to the radio application.
GMSK using a sound card - this method uses a computer sound card to generate GMSK modulation and de-modulation. The primary software for this method is developed by Jonathan Naylor. An example of a repeater system using this technique is the addition of D-STAR to the Yaesu DR-1X repeater by attaching the UDRC and a Raspberry Pi computer. [28]
A software GNSS receiver is a Global Navigation Satellite System (GNSS) receiver that has been designed and implemented using software-defined radio.. A GNSS receiver, in general, is an electronic device that receives and digitally processes the signals from a navigation satellite constellation in order to provide position, velocity and time (of the receiver).
Software defined television; In embedded design, the role of software defined equipment or apparatus (SDE/SDA) can be defined by using direct firmware update (DFU) by over-the-air (OTA) action. OTA/DFU is a process where the firmware of an embedded system can be replaced wirelessly and remotely. This feature provides a powerful tool to redefine ...
Flipper Zero is designed for interaction with various types of access control systems, radio protocols, RFID, near-field communication (), and infrared signals. [6] [7] To operate the device, a computer or a smartphone is not required; it can be controlled via a 5-position D-pad and a separate back button.
