[amsat-bb] Pratham: IITB Student Satellite

Mon Oct 17 10:27:44 UTC 2016

Hello everyone,
Hope you all are doing good. When we were tracking Pratham today, we heard
a faint signal. The signal might have been weak possible because of the low
elevation of the pass. So we have a hope that the satellite might be active
again. Will it be possible for you to try tracking Pratham today?
Thanks,
Team Pratham
