Heard David Wolf in several QSOs while I quickly switched over from packet to voice uplink frequency. Didn't Seem to be much of a pileup. David signed saying they needed to get up early for the EVA.There was a minute of silence and then I heard a Russian voice giving the RS0ISS call. I managed to have a quick QSO with Sergei. I heard him make one or two more contacts before LOS. My QTH is Eastern MA, FN42
