This an attempt to implement the WinMOR soundcard protocol in a cross-platform modem with a GUI different from the original RMSExpress that targeted Windows only. The GUI is called RMSLink, and software defined modem is a separate project module for transmission of data over HF Radio. Written in C++ using Nokia Qt SDK. A programmer API will eventually be built for the modem module. Support for Windows, Linux, Mac OS X. We will leverage existing open source code for basic channel implementation of multiple modes including WinMOR and PACTOR-I.
