The Repeater Controller is developed to be used in amateur radio repeaters.  The Controller is available as a PCB with all parts soldered (no kit), or with enclosure.
You can select 3 ways of accessing the repeater or a combination of these, which are 1750 Hz tone (EU), CTCSS and DTMF.
A GUI (Graphical User Interface) application is developed for changing of parameters and upload of firmware and speech messages.  Speech messages can also be changed using a radio.
A 5-digit DTMF code used by the repeater keeper will set the controller in sysop mode, and the keeper can change most repeater parameters using DTMF.
If you like to make a link to another repeater, a link radio operating on a different band can be connected.  If the repeater keeper want to have a secret frequency where he is doing sysop tasks, a command RX can be connected.
By using two radioes, a X-band repeater can be build, and this will function as a normal repeater operating on two different bands.
