An Introduction to Software Defined Radios By Jeff Blaine, AC C July 2009 Rig types: SCR vs SDR ----------------------------------- Modern rigs are largely of the SCR variety meaning Software controlled radio. The major functions of the rig are implemented in hardware, with a dedicated microcontroller providing rig management and interface and (since the late 1990 s) usually with a DSP section to provide specialty signal processing ( filtering, noise reduction, notch). Rigs of the SCR type are generally fixed function with firmware updates (in some cases) providing somewhat optimized function, bug fixes and improved DSP performance.
