Their grant is dated 11/29/2006 with provison construction of first satellite must be complete with in 4 years or before 11/29/2010. Else they lose their US license.

Given that is just 10.5 months away, the satellite specs should be finalized and coordination with Dish and DIRECTV should be able to be made... Somehow I have a feeling that there still are no specs, no way to coordinate, just a stall tactic. Perhaps they do (as mentioned above) want to be bought out or bribed. Dish wanted that 104.5 slot for a long time. S5 should be able to precisely show the interference and problems if they have their satellite plan done and it is entering the final stages of construction. This is not something that is going to be slapped together the night before.
