An apparatus for communicating utility usage information at a utility usage location to a utility usage registering device includes a utility usage registering module adapted to be located at a utility usage location to provide a first signal indicative of the utility usage information, a transmitter responsive to said first signal for periodically transmitting at a pseudo-random transmission intervals, a second signal indicative of utility usage, a receiver located remote from the utility usage location for receiving the second signal, and a utility usage registering device associated with the receiver for storing the second signal indicative of utility usage information. A tamper detector is provided to detect the occurrence of a tamper event and generates a tamper signal which is directed to the utility usage registering module. The tamper signal is indexed upon the tamper detector sensing the occurrence of each tamper event.
