A tuned circuit is provided for connection to a transmitter of a power line communication system. The tuned circuit comprises components selected to provide a low impedance path to ground for a power line communication signal of a preselected frequency. When the transmitter is not in the process of transmitting a power line communication signal, it causes a shorting switch to be closed which shorts a secondary winding of a transformer of the tuned circuit. Therefore, during periods of time when the transmitter is not transmitting power line communication signals, spurious signals on the power line are diverted to ground and not permitted to travel to remote receivers connected to the power line distribution system.
