Following release on June 29, 2017, by its creators Joe Taylor, K1JT, and Steve Franke, K9AN, along with the software package WSJT, [1] FT8 was ...
Firmware. Firmware is commonly stored in an EEPROM, which makes use of an I/O protocol such as SPI. In computing, firmware is software that provides low-level control of computing device hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality. For a more complex device, firmware ...
Wikimedia Commons has media related to Radio modulation modes. Signals sent by radio (or over long wires or when stored on magnetic media) must be modulated with some method that prevents their signal from degrading before the signals can be received. A transmitter and receiver must use the same mode of modulation to successfully communicate.
