•Originally exclusively
radio-quiet, but the first radio-loud BALQSOs found by Becker
et al. 1997 and Brotherton et al. 1998. From Becker et al. (2000), 90%
of the radio-selected BALQSOs are compact in FIRST
maps (vs. 60% in the non-BAL sample), and BOTH steep and flat radio spectra
are present.
•Seems to rule out simple
orientation schemes, right?
