SIMPLEX is designed to help you create a radio repeater, featuring compatibility for both simplex and duplex channels. It can prove useful in performing modulation tests, supporting CW, SSB, FM, SSTV and other modes.

Handles both simple and duplex repeaters

The application features two operation modes, namely 'Simplex' and 'Duplex'.
