ARGO
The ARGO is a simple, robust user interface device suitable for connection to either the ARK2 or KMC. It allows independent control of volume and channel on up to two radios and includes transmit and receive channel indication. Both knobs utilise absolute angular position encoders and have no direct connection to the PCB.
Four buttons are provided (with mechanical limit on travel) on the ARGO for various control functions with a fifth button (red) reserved for initiating an emergency Selcall sequence. LED’s indicates the location of all buttons for night-time use and a light sensor is provided to automatically control display intensity under various lighting conditions (e.g. tunnels).
