  We present three high resolution radio images of the Crab nebula, taken in
1998.6, 1998.8 and 2000.1 with the VLA. These are the best radio images of the
Crab to date. We show that, near the pulsar, there are significant changes
between our three observing epochs. These changes have an elliptical geometry
very similar to that of the optical wisps. One radio wisp in particular can be
unambiguously identified between two of our observing epochs, and moves outward
with an apparent velocity of ~0.24. The similarity in both morphology and
behavior of the present radio wisps to the optical wisps suggests that they are
associated. This implies that the radio wisps, like the optical ones, are
likely manifestations of the shock in the Crab pulsar's wind. This suggests
that the radio emitting electrons are accelerated in the same region as the
ones responsible for the optical to X-ray emission, contrary to most current
models.
