Sky q and freesat
Sky are changing everyone to Skyq and this should be done by 5 years or so. If a customer stops subscribing the Skyq box must be returned so a customer wont be able to put his SkyHD box back in as LNB is wideband - unless a hybrid LNB was fitted. In any case once everyone has Skyq, there will be no use for the SkyHD transponders so they will be turned off so you'll have to get a Humax(eg)box to get on the freesat platform.
Or am I missing something...
