  We present here the first results of a 22cm survey of the Shapley
Concentration core. The observations were carried out with the Australia
Telescope Compact Array. Our radio observations completely and uniformely cover
the A3558 complex, allowing a thorough multifrequency study, by comparison of
our results with the available optical spectroscopic and X-ray data of the
whole chain.
  We will present here some statistical results of our survey and compare them
with the information on the dynamics of the chain and on the properties of the
intracluster gas. Attention will also be devoted to the extended radio galaxies
found in our survey.
