Strange stars with a crystalline color superconducting crust can sustain large shear stresses, supporting torsional oscillations of large amplitude. Moreover if a bare quark matter surface is present electrons spill in the star exterior forming an electromagnetically bounded atmosphere hundreds of Fermi thick. We investigate the electromagnetic signature connected with a torsional oscillation of the crust. The emitted power could be of the order of 10^51 erg/s. The emission is in the radio frequency band with estimated relaxation times ranging between milliseconds, for a 1 km thick crust, to minutes, for a 9 km crust.
