New channel plugin to support DMR and D-Star
Using DSDcc library which is a rewrite of DSD program as a C++ library a new DSD Demodulator channel plugin has been written. At present it decodes the following formats:
- DMR/MOTOTRBO: European two slot TDMA standard. MOTOTRBO is a popular implementation of this standard.
- D-Star: developed and promoted by Icom for Amateur Radio customers.
DSDcc itself uses mbelib to decode AMBE frames. While DSDcc is intended to be patent-free, mbelib that it uses describes functions that may be covered by one or more U.S. patents owned by DVSI Inc. The source code itself should not be infringing as it merely describes possible methods of implementation. Compiling or using mbelib may infringe on patents rights in your jurisdiction and/or require licensing. It is unknown if DVSI will sell licenses for software that uses mbelib.
If you are not comfortable with this just do not install DSDcc and/or mbelib and the plugin will not be compiled and added to SDRangel. For packaged distributions just remove:
- For Linux distributions:
plugins/channel/libdemoddsd.so - For Windows distributions:
dsdcc.dll,mbelib.dll,plugins\channel\demoddsd.dll
If you choose to compile and install this plugin you will need to have DSDcc installed in your system. Please follow instructions in DSDcc readme to build and install DSDcc. If you install it in a custom location say /opt/install/dsdcc you will need to add these defines to the cmake command: -DLIBDSDCC_INCLUDE_DIR=/opt/install/dsdcc/include/dsdcc -DLIBDSDCC_LIBRARIES=/opt/install/dsdcc/lib/libdsdcc.so
If you have mbelib installed in a custom location, say /opt/install/mbelib you will need to add these defines to the cmake command: -DLIBMBE_INCLUDE_DIR=/opt/install/mbelib/include -DLIBMBE_LIBRARY=/opt/install/mbelib/lib/libmbe.so
Please refer to DSD demodulator readme.md for details on the GUI.
