[QUOTE="Analoguesat, post: 1140911, member: 176362"] No reason why any of the tp's coundnt carry analogue if so desired. A satellite tp is basically just a "bent pipe" in apace - it reflects down to earth what it receives on the uplink. There is some fancy frequency shifting & amplification but its nothing particularly special. The ONLY reason analogue transmissions got shut down in favour of digital is spectral & cost efficiency. If you can transmit 15 digital channels in the same spectrum as 1 analogue channel you immediately cut individual channel running costs by a factor of 15. And if you rent 10 tps then you can transmit 150 channel instead of 10. [/QUOTE]
