The present invention provides a digital code combination apparatus connected beneath a short wave analog frequency dividing apparatus. The digital code combination apparatus of the present invention comprises a peripheral device constituted by a binary code combination device (4) adopting a digital dividing system (IC),which is connected beneath a transmitting analog frequency dividing device (3) of short wave (2MHz to 29.99MHz), wherein the frequency dividing device (d) carries out space wave long distance radio communication by using an ionospheric reflection propagation; and a peripheral device constituted by a binary code combination device (8) adopting a digital dividing system (IC), which is connected beneath a receiving analog frequency dividing device (7). The digital code combination apparatus of the present invention connects the binary code combination device (4) to the transmitting analog frequency dividing device (3) to perform a transmitting operation in the code of the binary code combination device (4), and a receiving operation in the code of the binary code combination device (8) connected to the receiving analog frequency dividing device (7). |
