The 8PSK modulation already in use those Ka bands off 99W and 103W clusters.
Oh I thought DirecTV was only using QPSK 3/4 FEC on Ka. I was wondering if they would use 8PSK Turbo FEC.
I'm just curious if there will be a throughput improvement on these new birds. Squeezing every last drop of efficiency out of each transponder, like how some birds out there are getting 8 HD channels on one tp or 70mbps. (Not DirecTV).
