1.3 Introduction
Thank you for choosing the FDM-DUO. It is an innovative dual mode SDR (Software Defined Radio)
transceiver covering the frequency range from 9kHz to 54MHz. The FDM-DUO can be used like a
standard transceiver in stand-alone mode or in remote mode to exploit the full potential of the ELAD
FDM-SW2 software. The FDM-DUO can still be connected to the FDM-SW2 software when it works in
"stand-alone" mode.
NOTE: For detailed information about ELAD FDM-SW2 software refer to user manual available at
