In this work, we have searched for quasi-periodic oscillations (QPOs) in the 15 GHz light curve of the FSRQ PKS J0805--0111 monitored by the Owens Valley Radio Observatory (OVRO) 40 m telescope during the period from 2008 January 9 to 2019 May 9, using the weighted wavelet Z-transform (WWZ) and the...
