  We are conducting a deep radio survey of a sample of 25 distant ($0.5<z<1$)
clusters of galaxies. Here we present a progress report. So far 17 of 25
clusters have been observed, to varying depths. We have found 33 radio sources
within 0.3 Abell radii of the cluster center, of which 28 are likely associated
with cluster member galaxies. A comparison of the radio luminosity function of
these clusters with the results of two surveys at lower redshift, reveals no
evidence for strong evolution in the population of cluster radio galaxies at $z
\sim 0.65$.
