Seems that some initial images did come down for about the first hour after the system was first enabled but then the system was only keying down at the proper intervals (once every 3 minutes) and no audio was being relayed.
Later in the day, the carrier switched to 145.825 and then about 1555 UTC, a partial image was transmitted. Reports after that seem to indicate the crew powered the system down as scheduled.
Congrats to those that were fortunate enough to copy imagery and we will hope the operation will have better success tomorrow.
Thanks to CR7/PY5RX for this image.
