Amazing that they had the ability to do widescreen in 1990 - Sky wouldn't have it until the digital service 8 years later. I believe the Channel Allocation menu was used to set the order of the satellite channels. 4, 8, 12, 16 and 20 were the BSB frequencies (Now, Galaxy, The Sports Channel, The Power Station and The Movie Channel respectively). The others, I think, were the Irish DBS allocations which the Irish government auctioned off (as they had no intention of using them), which could have expanded BSB to a 10 channel service.
May be I should goto the place where QVC is broadcast (which used to be the bsb headquarters) and ask how to subscribe to the service take the box and manual and dish
BSB was technically better than Sky using top quality component RGB tape playback and studio-camera-to-satellite RGB output plus lovely crystal clear digital stereo sound, over fuzzy fair quality moiré patterned crosscoloured PAL and compressed analogue Wegener Panda 1 noise reduction encoded stereo / mono / multilingual soundtracks and additional radio stations.
Lee DJ, This is 2018, Yes it worked under British Sky Broadcasting back then You wont get no satellite signal from this receiver no more, it all digital now, Analogue satelite tv is dead.
