yes. you can re-align the Dish towards 93.5e GSat-15 and tune the DD Freedish channels. There are around 100 channels available as FTA in MPEG-2 format, of which 90% are hindi language channels. No south language channels except the Dooradarshan regional channels.
Please note that DD Freedish will change over to MPEG-4 format (they have been telling that for long, don't know when it will happen)
