Abstract A series of solar radio bursts were observed in AR NOAA 10486 with the Solar Broadband (1.1--7.6 GHz) Radio Spectrometers (SBRS of China). Here we analyze four significant events associated with CME events and strong X-ray flares that occurred on 2003 October 22, 26, 27, 29. The Oct. 26 event is a long duration event (LDE) with drift pulsation structure (DPS), narrowband dm-burst (DCIM), and more than seven types of Fine Structures (FSs); its time of the maximum flux (07:30 UT) is about half an hour later than the X-flare (06:54 UT).
