The SCR-504-A Radio Direction Finding Set is a portable suitcase direction finder powered by accumulators, the receiver itself BC-792-A covers 100 kHz to 65 MHz in eight bands, reception modes AM and CW (A1).
The set SCR-504-A consists of the receiver BC-792-A, powered by a 6V BB-51 heaters accumulator and two BB-52 36V plate voltage batteries wired in series. The accumulators can be charged from the PE-128-A battery charger operated from a 6 or 12V DC car battery installation, the battery charger is connected to the receiver by means of a CD-658-A power cord, the matching headphones for the receiver are HS-34-A hearing aid earphones.
A small panel of controls is positioned below the carrying handle. These control the volume of signals received. An internal loop antenna is used for direction finding, a small sense button can be depressed to switch to the rod antenna as an auxiliary antenna for sense determination, to determine the direction of a signal from the ambiguous bearing.
The BC-792-A was used by US Military Intelligence. When carried as a normal suitcase, a small panel of controls below the carrying handle lets the operator access the controls while operating the receiver being carried around.
