Abstract: A communication receiver (12) is provided having a radio frequency section (20) for receiving a communication signal (14) and a corresponding code signal (16) carrying an identification code. An intermediate frequency section (26) is coupled to radio frequency section (20) to convert the frequency of said communication signal. A decoder (42) having a memory for storing a security code, is coupled to radio frequency section (20) and intermediate frequency section (26). Decoder (20) is operable to compare the identification code and the security code and selectively disable the intermediate frequency section in response.
