The Korean radio broadcasting system is analog. Compared with digital radio, the analog radio decreases the frequency efficiency. HD Radio is the method where the digital signal is transmitted on either side of the analog PM signal. Therefore, without relocating the analog frequency can transmit digital signals. If interference between analog and digital signal occurs it is impossible to receive smoothly, so HD Radio interference with existing analog PM will be analyzed. In this paper, based on Mt.Gwae-Bang stations within +-400kHz frequency of l03.5MHz, and to use the station to station by specifying the HD Radio channel interference, place the structures were analyzed. Through this paper, the reader of a digital radio frequency interference in the system know that it may obtain information about.
