Interested people in the community are welcome to become financial voting Members of CDR Inc. or to become financial Subscribers to MAINfm. Visitors to our facilities are welcome but please phone first to make arrangements. Our call sign – MAINfm is representative of our base in Castlemaine, Victoria and our broader reach.
