Resistive wall modes during the setting-up phase of a reversed field pinch have been investigated in an experiment (Reversatron II (IEEE Trans. Plasma Sci. {bold PS}-{bold 16}, 667 (1988))) operated without a conducting shell. The time for the vertical field to penetrate the vacuum chamber (4 {mu}sec) is much shorter than the rise time of the plasma current (100 {mu}sec). The discharges, when compared to discharges in the same device with a conducting shell, have a greater resistance and lower plasma current. Magnetic probes indicate the growth of a strong {vert bar}{ital n}{vert bar}=6 helical kink resonant with the field on axis.
