the signal from my cable provider is OK (it works on windows)

PWM parameter??? i searched for it and it seems it is a kind of 
frequency adjustment, but as i am new to linux i do not know where/how 
to set/change this. any hints howto do this?

if have similiar output with czap (same freq etc. here)
status 00 | signal 8989 | snr b4b4 | ber 000062d4 | unc ffffffff |
status 00 | signal 8585 | snr b9b9 | ber 000062d4 | unc ffffffff |

status 00 | signal 8787 | snr b8b8 | ber 000062d4 | unc ffffffff |

but no FE_HAS_LOCK and status is always zero except the single line with 
"06", but i don't know what this means... )-:

are you using kernel 2.6.10 and latest firmware or anything else???
