Hi all, the saga goes on: my TT-3200 gets the carrier on a transponder (freq=11495MHz, srate=30MS, FEC=5/6, polar is vertical) which is known to work (checked with my STB). So what is not working is the demodulation, so stb0899 I guess. Here is a snippet of dmesg during an unsuccessful tuning to this transponder: [56993.647796] stb0899_get_params: Get DVB-S params [56994.145488] dvb_frontend_thread: Frontend ALGO = DVBFE_ALGO_CUSTOM, state=16 [56994.145494] stb0899_search: set DVB-S params [56994.145498] stb0899_search: delivery system=1 [56994.145501] stb0899_search: Frequency=1745000, Srate=30000000 [56994.145504] stb0899_search: Parameters IN RANGE [56994.145725] _stb0899_read_reg: Reg=[0xf1c2], data=78 [56994.145944] _stb0899_read_reg: Reg=[0xf1c3], data=07 [56994.145947] stb0899_set_delivery: Delivery System -- DVB-S [56994.146163] _stb0899_read_reg: Reg=[0xf533], data=08 [56994.146168] stb0899_write_regs [0xf533]: 08 [56994.146343] stb0899_write_regs [0xf548]: b1 [56994.146516] stb0899_write_regs [0xf549]: 40 [56994.146689] stb0899_write_regs [0xf54a]: 42 [56994.146862] stb0899_write_regs [0xf54b]: 12 [56994.147243] _stb0899_read_reg: Reg=[0xff11], data=c0 [56994.147246] stb0899_write_regs [0xff11]: c0 [56994.147422] stb0899_write_regs [0xf1c2]: 78 07 [56994.147630] stb0899_set_mclk: state->config=f8c0fc00 [56994.147633] stb0899_set_mclk: mdiv=21 [56994.147636] stb0899_write_regs [0xf1b3]: 15 [56994.148023] _stb0899_read_reg: Reg=[0xf1b3], data=15 [56994.148026] stb0899_get_mclk: div=21, mclk=99000000 [56994.148029] stb0899_set_mclk: MasterCLOCK=99000000 [56994.148031] stb0899_search: DVB-S delivery system [56994.148244] _stb0899_read_reg: Reg=[0xf12a], data=48 [56994.148247] stb0899_i2c_gate_ctrl: Enabling I2C Repeater ...

Note that the card works great on 4 other transponders (11093,11555,11635,11675 MHz) the only difference being the FEC (the 4 others are 3/4). So my question is: how can we fix that? Or at least how do we gather data so someone in the know-how could fix that?
