dc.descriptionMonitoring results are presented for the Stangellini 1 Jy GHz-peaked-spectrum source sample, illustrating that several members exhibit variability in total flux and/or linear polarization over timescales of order a decade. The variability occurs while the spectrum, based on the integrated fluxes, remains steep and characteristic of a transparent source. Total flux variability is unexpected in view of recent VLBI observations indicating no or hidden cores in several members. However, both the variability, and the detection of circular polarization in one class member, argue for the presence of opacity in some portion of the radio jet.
