Abstract
A radio controlled clock includes a main unit and interchangeable antenna modules. The main unit includes an operating circuit and contacts. The circuit has a CPU and decoders for decoding RF time signals having different carrier frequencies received by the modules. The decoders are connected to the contacts. Each module has a body connectable to main unit body, an operating circuit, and contacts connectable to the contacts of the main unit when a module is connected to the main unit. The circuit of the main body includes a receiver tuned to receive a RF time signal having a specific carrier frequency broadcast in a particular country and sends the signal received, via the contacts to a decoder, enabling the CPU to display the local time on a display.
