| // SDRangel can serve as a remote SDR front end that handles the interface       //
 | |
| // with a physical device and sends or receives the I/Q samples stream via UDP   //
 | |
| // to or from another SDRangel instance or any program implementing the same     //
 | |
| // protocol. The remote SDRangel is controlled via its Web REST API.             //
