Abstract
We analyse the rest-frame UV spectra of a complete sample of optically selected radio-loud and radio-quiet QSOs. Our results are: 1:Broad absorption-line QSOs (BALQSOs) are all radio quiet, but they are strongly clustered toward the top end of the radio-quiet population in radio power.2:Radio-loud QSOs have higher equivalent-width, narrower high ionisation emission-lines than radio-quiet QSOs.3:Further ReadingSee Francis, Hooper & Impey, 1993, Astronomical Journal 106, 417 and references therein for more details and discussion.
