AB: DH (decameter-hectometric) type II radio bursts observed by Wind/WAVES spacecraft are associated to the shock propagation driven by CMEs ( white-light Coronal Mass Ejections) which are observed by the Solar and Heliospheric Observatory (SOHO).In previous results (Rosas, et. al. 2004), a chronological order was found between CMEs, solar flares, DH type II and metric type II radio bursts to be CME-Flare-DH type II-Metric type II. The study period, 1997-2004, is still within the solar cycle (23) between minimum and nearly to the end of the cycle. We find no change in the chronological order of events. A closer examination of the data concentrating on only those events that contained all four types of solar phenonmena, 135 events were found to have a solar cyclic variation. Further study into these events are necessary to find interplanetary conditions to observe dynamic spectra of DH type II radio bursts which are not always seen when CMEs are fast and wide.
