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....
