It would appear that DOD channel 4384, Arts channel 4563, the Marquette MI, Bend OR, Lima OH, Parkersburg WV, St Joseph MO, Eric PA, Sioux City IA, Columbus OH, Wausau WI, Charleston WV, Dayton OH (OK, among many other DMAs) SD locals are in mpeg2 QPSK (on various spotbeams), and in 8PSK we have Alpena MI, Alexandria LA, Jonesboro AR, Victoria TX SD locals, and I've stopped looking. There are probably many more. Note that a 311 can decode both QPSK and 8PSK modulation.
