Problem was the bad Battery voltage telemetry went from nominal 6v readings down to 1.4v or so (140 count). FInally looked at telemetry closer as shown here: http://www.findu.com/cgi-bin/tele2.cgi?call=psat2-1&last=20 And it is clear that the voltage channel (red) tracks the current (green) perfectly which is the opposite of what one would expect. So clearly the voltage bit has become detached and the voltage reading (red) is just the phantom reading of an unconnected telemetry bit following its adjacent A/D channel.
So we have sent the command to turn off the PSK31 to see if battery recovers.
