The present invention relates to automatic determination of radio control unit configuration parameter settings. A method for determining an output signal is provided. A radio device identifier associated with a second radio device is stored in a first radio device. One or more configuration parameter settings associated with the second radio device are stored in the first radio device. The first radio device identifies the second radio device based on the radio device identifier. In response to identifying the second radio device, the first radio device automatically determines the configuration parameter settings should be used to determine an output signal based on a user input. The first radio device establishes a radio communications link with the second radio device. The first radio device receives the user input. Based on the configuration parameter settings and the user input, the first radio device determines the output signal. The first radio device transmits the output signal to the second radio device through the radio communications link.
