Abstract
Four compact steep-spectrum quasars (3C 48, 3C 147, 3C 309.1, and 3C 380) have been mapped with a resolution of 20 mas at 329 MHz. The structures of all four objects are asymmetric and complex, but they are shown here to be consistent with a basic one-sided jet morphology. In this, they are quite similar to other classes of radio sources; however, their small scales and convoluted structures suggest that in these objects, other factors such as the interaction with the interstellar medium and/or variations in the initial jet direction significantly affect the morphology.
