I guess there is such a thing as 8PSK Turbo Coded too??
No need to PM...
Almost all of the satellites used for TV are simply bent pipes. They send out what they receive. So any signal thrown at them will come back down. Now if you use a high bandwidth signal without much FEC(forward error correction) then you'll need either/or a big dish or a strong signal. So on satellite slots like 77w where you have older satellites in spots they were not designed for you have to use a QPSK signal so you can have a sustainable decodable signal on the small residential dishes.
8PSK can be used on any DBS satellite.
Its just the modulation.....some are QPSK and some are 8PSK
Phase-shift keying - Wikipedia, the free encyclopedia
8PSK allows them to get more channels on a TP. Dish uses a mixture of both QPSK and 8PSK on satellites
I'm assuming that's why old satellites are able to carry HD channels but would have to be on a QPSK signal wich it's not the best way to do so due bandwidth usage?
nope. Echo 3 at 61.5 is the oldest satellite in the Dish fleet (that still is being used) and the HD on there is all 8PSK. That satellite is what 10-12 years old I think

but they used QPSK only with those. I dont remember any 8PSK on 148
This might be a little OT but I've always wonder how those great big "screen-like" antennas I see in some yards get their signals from? Do they have to go through E* or D* too? I remember years back (about 30 or 35) when I lived in Chicago, my friend's Dad, who lived in Kentucky, had one, but I never knew if he had to pay a provider for the signal, or just purchase the receiver and programing was free. Also, I remember my friend telling me that when they watched certain programs like Johnny Carson & live sporting events, they seen what was going on while broadcast TV showed commercials...I never witness this myself, so I always wonder if this was true.
Can any "Old Pros" out there set me straight on this?
