  Low-radio-frequency observations played a remarkable role in the early days
of radio astronomy; however, in the subsequent three or four decades their
usefulness has largely been in terms of the finding-frequency of surveys.
Recent technical innovation at the VLA has meant that spatially well-resolved
imaging at low frequencies is now possible. Such imaging is essential to
understanding the relationship between the hotspot and lobe emission in
classical double radio sources, for example. We here present new images of 3C
radio sources at 74 MHz and 330 MHz and discuss their implications.
