Found some more information on the BBC reception site, (http://www.bbc.co.uk/reception/news/index.shtml#freesat), the radio channels via sat were moved in the last months and it warns that if you don't retune your box (not a skybox, just other receivers) that you would lose the channels - this is now the case via cablecom in Basel. from the current FAQs on the beeb site :

Why can I no longer receive some BBC radio stations via satellite?
Some BBC radio stations on satellite have moved their location. If you have a Sky satellite receiver you need do nothing, but if you have a 'free to air' type receiver you will have to make the changes manually, otherwise you will eventually lose the stations. You can find details on this page - channels with changes are marked.
