We report on our Chandra Cycle 9 program to observe half of the 60 (as yet) unobserved 3C radio sources at z<0.3 for 8 ksec each. We compare the Chandra observations with VLA radio maps and HST data to search for extended emission from jets and hot spots. A comparison of X-ray flux maps in different energy bands provides photometry, an estimate of intrinsic absorption of nuclear emission and information on the emission of extended regions: diffuse emission around the nucleus, jets, and hot spots. We have found X-ray counterparts to 5radio hot spots; 2 knots in the curved jet of 3C17; and X-ray nuclear emission from all the radio galaxies in our sample with only one exception. Included in our sample are 3 Compact Steep Spectrum (CSS) radio galaxies and in one of these we studied the extended X-ray emission spatially associated with the optical emission line region. The work at SAO is supported by NASA grant GO8-9114A.
