MH Repeater Controller System: Ham Home

This is a windows based repeater controller. It uses the sound card build into your windows 95/98 system. This system lets you record messages for all the repeater messages using your own voice. You can remotely control all the supported functions over the air using an addon DTMF Controller board which you can build yourself. Interface to the repeater is via a simple keying circuit which plugs into the serial port of the computer. Manual is below. Download MH Controller Here. Requires VB3 runtime.
