Multi-frequency light curves and polarization variability data from the University of Michigan 26-meter telescope will be presented for selected active, extragalactic radio sources. The telescope, operating under automatic computer control for more than 25 years, is used in a program to monitor the linear polarizations and flux densities of more than 200 active extragalactic radio sources at 4.8, 8.0 & 14.5 GHz, using broad-band radiometers and polarimeters. Active sources are observed at all three frequencies on a weekly basis, with less active sources and special subgroups of sources being observed at monthly or tri-monthly intervals. Variability on time scales ranging from days to decades has been observed. Recent circular polarization measurements, showing variability in all four Stokes parameters, and the initial results from the new 24 GHz polarimeter system will also be presented. The observational data from the UMRAO program are available at URL: http://www.astro.lsa.umich.edu/obs/radiotel/radiotel.html.
