Hello All,
Just heard RS-22's CW telemetry for 2009/12/22 00:30 UTC.
RS22 UBS - 139 137 on board voltage/10v IBS - 20 20 on board current mA USUN - 146 0 solar cell voltage ISUN - 78 0 solar cell current mA ITXA - 0 0 ITXB - 0 0 TTXA - 111 111 TTXB - 109 109 TNAP - 110 110 TCTR - 110 110 TSBA - 107 108 TSBB 88 104 125 MODB 145 145 145 MODC 6 6 6 MTX 35 35 - MRX 34 34 -
Using details from Mike DK3WN's site to crunch the data, I come up with the following. USUN and ISUN give the the solar panel outputs as producing 14.6v at 78mA working during one frame and nothing during the next. I suppose this indicates a faulty solar panel. The satellite was in full sunlight during the pass. More monitoring needed.

Hi, I just caught RS-22 on the dark side !!
There is my result on a 30 deg pass at 01h15 UTC 22-12-2009
RS22

Hope this will help !!
Probably if the solar panels are defective... it explains why sometime we don't ear it... maybe....
