hi, get frequently big bursts here activating the poweramps protection circuit. why this: static int ves1820_get_frontend(struct dvb_frontend* fe, struct dvb_frontend_parameters *p) { struct ves1820_state* state = fe->demodulator_priv; int sync; s8 afc = 0; ... p->u.qam.fec_inner = FEC_NONE; and this: for userspace apps? static struct dvb_frontend_ops ves1820_ops = { ... .info = {... .caps = ... FE_CAN_FEC_AUTO ??? its turn off, isnt it? and no functions for setting it, but theres some correction: schorpp@tom1:~$ femon using '/dev/dvb/adapter0/frontend0' FE: VLSI VES1820 DVB-C (CABLE) status 1f | signal ffff | snr e1e1 | ber 000317cc | unc ffffffff | FE_HAS_LOCK status 1f | signal ffff | snr e1e1 | ber 000317cc | unc 00000000 | FE_HAS_LOCK status 1f | signal ffff | snr e1e1 | ber 000315d8 | unc 00000000 | FE_HAS_LOCK status 1f | signal ffff | snr e1e1 | ber 000315d8 | unc 00000000 | FE_HAS_LOCK so its on? or is this a pre-stage error correction. vlsi is philips now, so if none has a register datasheet, so pls someone say register address and FEC values possible... to check it out. static u8 ves1820_inittab[] = { 0x69, 0x6A, 0x93, 0x12, 0x12, 0x46, 0x26, 0x1A, 0x43, 0x6A, 0xAA, 0xAA, 0x1E, 0x85, 0x43, 0x20, 0xE0, 0x00, 0xA1, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x00, 0x02, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x40 }; which one? y tom
