We present a preliminary analysis of new VLA observations of the nearby spiral galaxies M51, M101 and NGC3184. As part of a larger Very Large Array (VLA)/Chandra survey of spiral galaxies, we obtained high resolution VLA observations of each galaxy. Observations were taken in the spring of 2002 (20 cm) in the VLA A-configuration, and in the winter of 2003--2004 (6 cm) in B-configuration. Many point sources have been detected in each galaxy. The results for a few of the sources will be presented here. With complementary Chandra observations we are for the first time able to definitively classify some sources. This type of analysis has been useful in identifying supernova remnants and also potential X-ray binaries in the galaxy M83. A more complex X-ray analysis is currently in progress and will be forthcoming in a later paper.
