SvxLink is a flexible general purpose voice services system for ham radio use. It can act as a repeater controller or operate on a simplex channel. The server consists of a core that handles the connection to the transceiver. The transceiver audio is connected to the PC through the sound card, and the PTT is controlled by a pin in the serial port. The voice services are loaded into the core as modules. Examples of existing voice services are a help system, a module that plays back everything you say, a module to connect to other EchoLink stations, and a voice mail module. The project also includes an EchoLink client GUI application (Qtel).
