(There is a local oscillator+downmixer in there...) This is what the one here has info = { name = "ST STV0299 DVB-S", '\000' <repeats 111 times>, type = FE_QPSK, frequency_min = 950000, frequency_max = 2150000, frequency_stepsize = 125, frequency_tolerance = 0, symbol_rate_min = 1000000, symbol_rate_max = 45000000, symbol_rate_tolerance = 500, notifier_delay = 0, caps = (FE_CAN_INVERSION_AUTO | FE_CAN_FEC_1_2 | FE_CAN_FEC_2_3 | FE_CAN_FEC_3_4 | FE_CAN_FEC_5_6 | FE_CAN_FEC_7_8 | FE_CAN_FEC_AUTO | FE_CAN_QPSK)}, Frequency_min and max match yours. Try a different scan tool, and make sure you get a signal out of your LNB. Proper DISH ALIGNMENT is important, and don't forget a grounding bloc. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
