Abstract
A well defined sample of 72 Gigahertz Peaked Spectrum radio sources is compiled, having turnover frequencies in the range of 0.5 - 10 GHz. U sing this sample, the canonical GPS radio spectrum is constructed, whi ch is found to have a constant shape, independent of AGN type, redshif t or radio luminosity. A possible deficiency of low turnover frequenci es at high redshift is found, which may reflect a physical mechanism w here turnover frequency and radio luminosity are correlated.
