Abstract
RADIO spectra for the highly redshifted z ≥ 3.40 quasars OH471 (ref. 1) and OQ172 (ref. 2) are presented here for frequencies between 16.7 MHz and 85.3 GHz. The spectra are complex. Both have a peak at or near 1.4 GHz and a second peak near or above 85 GHz. Both have a low frequency cutoff, the one for OH471 being especially sharp. OH471 sometimes seems to be variable at 31 GHz on a time scale of days but the source appears to be stable at 10.7 and 22 GHz. © 1974 Nature Publishing Group.
