The much improved and enlarged sample of clusters from the MX Northern Abell Cluster Redshift Survey was the basis for a study of the correlation of the radio properties of clusters with large-scale structure. We have tested the hypothesis that the presence and properties of radio sources of various types within clusters could be partially the result of larger scale processes, such as the merger of clusters and the infall of matter from more extended structures. Images from the NVSS, as well as catalogs of radio objects from the literature, were used to determine numbers of point and extended sources within each of the R \ge 1 clusters in the sample, which is more than 95% complete in measured redshifts. Other properties, such as orientations of extended sources and the presence of radio halos, were also examined. We present the results of several analyses (nearest-neighbor-cluster, local spatial cluster density, correlation function) examining the influence of the environments of clusters on their radio characteristics.
