Still active at 0530 UTC on all four ground frequencies
FYI - the vox freqs a/w morse markers are 5606khz, 6689khz, 8884khz, and 11324khz, all usb. 6689 seems to be the most active, I've only noted 11324 once. 12735khz is NOT a/w morse markers, it is a separate net which seems to be dedicated to Northern Sea Route ice reconnaissance.
