  We report on the measurement of the hadronic cross section below 1GeV at the
electron-positron-collider DAPHNE, using the multiple purpose detector KLOE.
The radiative return, which is due to initial state radiation (e+ e- \to gamma
+ hadrons), allows us to obtain the cross section for variable
center-of-mass-energies of the hadronic system from the 2m_pi threshold up to
1.02GeV. This measurement can be performed while DAPHNE is running with a fixed
accelerator energy on the phi mass (1.02 GeV). For the exclusive process e+ e-
\to pi+ pi- gamma, the status of the analysis and first preliminary results of
the invariant mass spectrum of the two-pion-state are presented.
