It took a couple of days but finally a sign from PRATHAM on 145.980. The signals are weak but you can decode the signals. Now lets try to received the AFSK 1200 signals when the satellite is over there second ground-station in France.

The identification on 145.980 is:

VU2BUG PRATHAM IIT BOMBAY STUDENT SATELLITE
VU2BUG PRATHAM IIT BOMBAY STUDENT SATELLITE
VU2BUG PRATHAM IIT BOMBAY STUDENT SATELLITE
VU2BUG PRATHAM IIT BOMBAY STUDENT SATELLITE

Fingers crossed that the satellite will also become active on 437.455 with 1200bd AFSK.
