Hmm....this Russian report claims that the intermittent telemetry isn't due to anything wrong with the Progress, but with the Soyuz rocket - which put it 30 km too high! (presumably referring to the apogee)
Hmm....someone reminded me that NORAD's orbit of object B (which is much higher than that of A) seems to corresponds to what Progress should end up after making its first burn automatically at 07:52 UTC (the epoch is at 08:28 UTC). If so, maybe it has already done the 2nd one (at 08:29 UTC) as well which would probably put it to safety for now.

The perigee is still low, just barely above the NASA definition of Entry Interface (400k ft, 121.920 km).
As for KURS issue - as far as I understand, this Progress is to use new KURS antennae (which are to be used on Progress-MS), so issues with them are not totally unexpected.
