I guess some of this needs to be honed a little more on the site, right now the system supports 1 duplex port (RX/TX), but we are building the support for multiple ports (i.e. for RF Link radios). It supports all the basic stuff that you’d expect from a controller including customizable ID and Courtesy tones. With the 1.1.0 release we are about to make there is more control in those areas now giving more options than 1.0.0. It comes with some stock sounds and can speak the callsign of the repeater as well as ID with morse code. You can upload your own sound clips in WAV or MP3 also. It also has EchoLink built in. Without getting too wordy, that gives a general overview. After our 1.1.0 release I will have to update some things on the site to better outline this. Thanks.
