Introduction
Thank you for choosing the FDM-DUOr. It is an innovative dual mode SDR (Software Defined Radio)
receiver covering the frequency range from 9kHz to 54MHz. The FDM-DUOr can be used like a standard
receiver in stand-alone mode or in remote mode to exploit the full potential of the ELAD FDM-SW2
software. The FDM-DUOr can still be connected to the FDM-SW2 software when it works in "stand-
alone" mode.
NOTE
