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.
