Radio spectra of the 25 BAL and 34 non-BAL QSOs (GHz on x-axis, mJy on y-axis). Error bars are shown when larger than the symbol size. Crosses represent flux densities from the literature, rhombi are flux densities from our observational campaign, and arrows are upper limits from the literature. Solid lines are fits to a parabola and dashed lines are fits to a power law. For resolved sources, flux densities are presented as follows: a square for C component (core) and triangle, asterisk, and dot for components A, B, and D, respectively (see Tables 5 and 6). For 1728+56, the flux densities at 4.8 and 8.4 GHz shown as asterisks correspond to the B+C components.
