ABSTRACT:
A remote controlled radio frequency receiver. A modulated carrier having a frequency F1 containing remote control data is received in a radio frequency receiver having a local oscillator and demodulator. The data contained in the received carrier is produced as digital data. A microprocessor executes commands represented by the digital data. The radio receiver frequency receiver is tuned by a frequency synthesizer which is incremented by a microprocessor to tune a frequency band containing the modulated carrier. A non-volatile memory is provided for storing the value of a carrier frequency, and the value of an access signal in the event a carrier transmitter fails to produce the modulated carrier containing the needed remote control data.
