[linux-dvb] Re: TechnoTrend PCI DVB-C 2.1 success

["Stefan Norberg" <stefan@orbisec.com>]

This sucks! Now, I am the only one not getting this to work in northern
europe again! :)

I never get FE_HAS_LOCK, FE_HAS_SYNC; only FE_HAS_POWER, FE_HAS_SIGNAL,
FE_HAS_CARRIER.

Can this be CAM-related? All content on my network needs a Viaccess CAM.
AFAIK, this has noting to do with the CAM at this stage?

Any hints on further debugging?

Hi,

My card just tuned in here in Helsinki!!!

I made a modification to dvb_frontend.c's fe_zigzag() to always keep the
initial frequency. Apparently this gives the card enough time to get a lock
on the signal; otherwise the frequency zigzagging loses it.

I suppose the signal quality is so bad here, that tuning often takes very
long. Or maybe some parameter is not exactly right but still makes tuning
possible if one waits long enough?

While the card is waiting for a lock, it sometimes gives a brief
FrontendStatus of 0x12 (it's otherwise constantly 0x00), which I understand
means there is some signal but not a lock.

Once finally tuned in, the status is 0x5A, which translates to FE_HAS_POWER
| FE_HAS_SIGNAL | FE_HAS_LOCK | FE_HAS_CARRIER | FE_HAS_SYNC.

A lot of thanks to Joachim for helping with this. I am no longer in a
completely desperate state of mind ;-)
