Yes the idea was to put all the SD services onto the hired in transponder while they shuffled all the BBC owned transponders. 10803 was the last to have its services moved off, without that extra capacity they'd have struggled to do it.

Now its all done it can all be moved back as is from 12422 onto 10803 which is BBC owned and uplinked.

12422 I think is the transponder that has been used before for temporary Red Button channels

I could understand if that was a DVB-S2 transponder, so they could increase the bitrate on all those SD channels, but it's no different configuration to 12422 H where they are now.

There's no such thing as a DVB-S2 transponder, it's a mode of transmission. The nightlight SD services can't be transmitted in DVB-S2 of course, the SD only boxes can't do S2. Hence the radio stations have to be on it too
