Abstract
Fifty-five variable radio sources have been observed at 90 GHz, 22 of them for the first time. The sources typically have flat spectra between 5 and 90 GHz. The dispersion of the spectral indices of the BL Lacertids is narrower than the dispersion for other objects. The variability of those sources previously observed is somewhat greater than observed by Owen et al. (1978); some sources exhibited the lowest flux densities ever recorded at 90 GHz. An upper limit of 0.14 Jy was measured for SS433 in July 1979.
