Radio precedes X-ray Compton luminosity by ~3 days in the rising hard state but lags by ~8 days in the decaying hard state of GX 339-4, with inner magnetic field strength estimated from accretion rate and truncation radius accounting for both.
Deep VLBI observations of four ULXs yield no compact radio detections and tight upper limits, disfavoring persistently bright hard-state-like compact cores.
