Abstract
On the basis of source positions determined by the Culgoora radioheliograph we suggest that metre-wave radio emission propagates from the Sun along under-dense magnetic flux tubes. Such wave ducting is able to explain several long-standing problems in regard to the positions, heights, and polarization of solar radio sources. Observed source heights then represent, not heights of wave generation, but heights of wave escape from under-dense flux tubes.
