We present radio observations at 6 cm for 93 ACO clusters, in which the brightest member consists of either two galaxies of roughly equal brightness inside a common halo (a dumbbell) or has multiple nuclei. A subsample of 27 dumbbell systems, belonging to a volume-limited sample, was observed with the VLA and ATCA. The remaining clusters were mapped with the VLA. The detection rate in the volume-limited sample is 44%. In all 93 clusters observed 43 brightest cluster members were detected in the radio. Parameters are presented for all the radio sources detected in the cluster fields.
