well any time we can get a frontend that supports 8psk let me know. :-)
Broadcom claims on the website 8PSK support for the BCM4500 chipset,
maybe they use it on one of the US satellite PCI cards. Zarlink claims a
DSS compatible mode for it's MT312 and the new ZL10312. Since I don't
know what modulation modes DSS specifies I can't tell you whether it's
BPSK, 8PSK or anything else. The MT312 is used at least on some of the
Skystar2 cards, don't know if you can get them running with one of the
US transmitters.
