The M_BH - L_rad Relation for Flat-Spectrum Quasars

In this proceedings we summarize our recent letter (Jarvis & McLure 2002) where we suggested that by correcting for the inevitable effects of inclination, the black-hole masses of flat-spectrum quasars (FSQ) with intrinsically powerful radio jets are confined, virtually exclusively, to M_BH

10^{8} Msolar. After considering realistic Doppler boosting factors, many of the FSQ would be more accurately classified as radio-intermediate or radio-quie t quasars. This range in radio luminosity suggests that the FSQ are fully consistent with an upper boundary on radio power of the form L_5GHz proportional to M_BH^2.5.
