  We suggest stellar oscillations are responsible for the strange radio
behaviors of Anomalous X-ray pulsars and soft Gamma-ray repeaters (AXP/SGRs),
within the framework of both solid quark star model and magnetar model. In
solid quark star model, the extra voltage provided by oscillations activates
the star from under death line to above death line. In magnetar model,
oscillations enlarge the radio beam so that increase the possibility to detect
it. Later radio emission decays and vanishes as oscillations damp.
