The Repeater Controller, or Logic, used on GB3BS is made by a company called Arcom who are based in the United States. The model in use on GB3BS is the RC210, as shown in the pictured below. It is extreamly flexible and has many features and can be locally or remotely managed or programmed.
Programming of the RC210 is based on Macro functions or pre determined functions that can be put together like building blocks. This method allows for a very flexible repeater controller and can be easily changed or added to. The scope of controlling a repeater can be made very simple or very complexed depending on the requirements.
The controller itself has been upgraded by the Repeater Group from an Atmel MEGA128 to the Atmel MEGA 256-1 Risc processor, and has the following key features, but not all of them are implemented or legal to use in the UK.
