Results of a VLA radio detection survey conducted for a large sample of broad-absorption-line (BAL) QSOs are presented. The absence of luminous radio sources among the 68 known BALQSOs under consideration, together with a complementary spectroscopic study which finds no BALQSOs among a large sample of radio-loud quasars, establishes a strong anticorrelation between luminous radio source and the BALQSO phenomenon. On the basis of a quantitative statistical test calibrated by Monte Carlo realizations, the long-suggested bimodal division of all QSOs into radio-loud and radio-quiet objects is found to be present at greater than 98 percent confidence level in several samples. It is suggested that QSOs produce either a highly collimated, powerful, relativistic jet that gives rise to luminous emission or to a subrelativistic, uncollimated wind that accelerates the BAL clouds, but not both.
