ABSTRACT:
A receiver for use in receipt of signals on railroad rails which converts the rail signal to a higher frequency and feeds the higher frequency signal into an input transformer. The secondary of the input transformer is in a tuned circuit which is resonate at the higher frequency and which contains a winding of an output transformer. The tuned circuit can be tuned to the higher frequency by series components such as a resistor and capacitor.
