[Jean-François Ménard]

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

UBS	-	134	134	
IBS	27	27	27
USUN	0	0	0
ISUN	0	0	0
ITXA	0	0	0
ITXB	0	0	0
TTXA	112	112	-
TTXB	111	111	-
TNAP	111	111	-
TCTR	111	112	-
TSBA	110	109	-
TSBB	91	85	-
MODB	145	145	-
MODC	6	6	-
MTX	35	35	-
MRX	34	34	-

Hope this will help !!

Probably if the solar panels are defective... it explains why sometime 
we don't ear it... maybe....
