Station Controllers Station controllers are used to manage remote HF stations, repeater infrastructure and other critical assets. The architecture is compatible with SRS the repeater control systems allowing you to deploy the site control system by itself or in combination with the repeater control systems. The system includes a master processor based on a Raspberry PI or industrial PC and allows for any combination of I/O modules including small signal relays, DC volt meters, digital switch closure inputs, RF power monitoring, RF coax switches, and more. |

Repeater Control Systems Our repeater control systems support from 1 to 8 ports with a full cross-bar electronic switch which allows any port to be connected to any port in any combination. The modular architecture makes it easy to upgrade, maintain and expand your system by just plugging in new boards. The analog audio path features a built in sub-audible tone filter, DTMR decoder, digital level setting pots and unique telemetry generation on every port. The supplied PC config software makes it easy to setup the system. Each port can be individually configured to be a repeater, RF link, VOIP link, or remote base radio. |

Adventure Radio Controllers
The Adventure Radio Controller (ARC) implements the proposed Adventure Radio Protocol defined by George KJ6VU. The protocol uses CTCSS tones to alert radio operators to various types of traffic found on the Adventure Radio Frequency. The Adventure Radio Controller decodes CTCSS and DTMF tones to control speakers, remote base radios and optionally interface to repeater and remote VOIP systems. <-- Prototype version pictured here. |
