No signal means they have not switched on the transponder yet. I have seen some post some where with strength of 10%. Not so sure of its genuineness. But I doubht hether the corresponding beam cover the entire nation or not. If it has covered so it should have sufficient strength. I think they can reduce or vary the signal strength.If the have plans to addi his transponder and all our forum members wish turn true then it will be a great news for airtel customers.
I heard from some retailers out here that Mazhavil Manorama HD will be added on the platform on22nd. Some says Asianet HD but untill now no official sources are there to support the news.
