I think Gsat10 also covering Andaman islands...Now tatasky users too getting signals there...Then y cant it be from Gsat10 itself? Just a assumption..C Band Channels currently running from Insat 4B bro @83*E . Yes Gsat 31 has 19 KU band Tps only i said this before also .In above pic It says coverage area to island also so after Gsat 31 Activation only Andaman Users Getting Ts signals as said before by Vadi bro . So all this indicates Gsat 31 is being used by Ts . Let's wait for official Update or a software update of ver.305 for Ts STBs.
