1. A method for carriage of a communications over a direct-current power circuit comprising of:

  • a. constructing a toroidal coupling coil with a low-permeability core material as a means of coupling the alternating-current high-frequency carrier onto the power circuit;

    b. constructing the toroidal coupling coil with at least 25 windings thus forming the secondary winding;

    c. threading a power conductor of the direct-current power circuit through the center of the coupling coil, thus forming the primary winding;

    d. generating an alternating voltage carrier signal of a certain frequency such that the dimension of the power circuit is smaller than one-quarter wavelength of said frequency, such as to prevent electro-magnetic radiation of the carrier and prevent induced interference at said frequency;

    e. modulating the alternating voltage carrier signal with a packet of digital information;

    f. applying the modulated alternating voltage signal to the secondary winding of the coupling coil for transmission, which is then induced as alternating-current onto the primary winding, superimposed on direct-current flowing through the power circuit; and

    g. inducing the alternating-current onto another similar coupling coil threaded onto another conductor of the same power circuit, as its primary winding, which is induced onto the secondary winding to result in alternating voltage input to a receiver-demodulator.
