The BFO does display an overshoot and settling period during the 1825 log on. My research found that the log on is both due to a repowering of SATCOM and then finally exposure of the right HGA to recommence the log on. The BFO overshoot sequence doesn’t actually match the previous logons, since the first BFO is correct and doesn’t display an overshoot.
The SATCOM is powered by the left Main AC bus. With so many left systems down following an oxygen bottle rupture, conducting the Left Main AC bus checklist will repower SATCOM.
