A switched-load, resonant transmitter (T2) for inbound signaling in a two-way automatic communications system (TWACS). The load is purely reactive containing both inductive (L) and capacitive (C) elements. When connected in a power transmission network, the transmitter generates signals useful for passband communications. The transmitter consumes, on average, 100 times less power than resistive switched-load transmitters currently in use in TWACS networks. Signal strength is comparable to that produced by the transmitters currently in use at frequencies near 1 kHz, but is very low otherwise.
