The results of a 1400-MHz survey with the NRAO 91-m telescope for radio emission in the directions of poor clusters that contain cD or other related galaxies are reported. A total of 51 clusters was observed and 37 sources with S/sub 1400/>150 mJy in 28 clusters were detected. We estimate that 16 +- 6% (8 +- 3 sources) of the poor clusters contain radio sources within 5 arcmin. The potential effects of cluster richness upon the probability of galaxy radio emission are discussed using this poor cluster sample and a similar radio survey of rich Abell clusters.
