Introduction, SDR control panel was designed to control SDR-transceiver. It allows to control the transceiver by tuning knob, provides controlling the bandwidths, modulation types, filters and many other functions included into SDR - programs.

Principle of panel's work, Control panel is designed to work with Expert SDR and ExpertSDR2 programs and provides the major functionality with it. Control panel is connected by USB interface to PC and at once becomes accessible in program Expert SDR.

Support of control panel in Expert SDR program

All accessible to the present day mechanic encoders functions are given in table 1. It should be noted that this list is not final. While development of the program new functions will be add stepwise.
