Re: Re : Twinhan 1041 (SP 400) lock and scan problems - the solution [not quite :(]

Manu,
 
Please specify what sattelite and what frequency cause problems.
Specify also a "good" transponder that locks.
Can you send me the stb0899 module logs (with debug severity)?
 
The tests I did are scanning all the satelites I have (5 in count) and see that the same transponders are constantly locked every scan.
The results are compared to Twinhan 1027 card as well (that's actualy was the trigger for me to start digging in the code since 1027 found more channels than 1041 and with 1041 channels were randomly dissapearing/reappearing every scan).
 
One of my sats is on edge recepition where many transponders are not locked, while my settop box shows then. But I actually didn't really expect the card to lock on them. So please check the sat coverage in your area. Its also known that some transponders are considered as weak and give poor signal even if they are supposed to be received.
 
Thanks.

Test report: it looks like good transponders (FEC 3/4, vertical
polarisation, SR 30M) that used to lock will lock a bit faster, so I'd
say that good things are now even more reliable and fast.
BUT the bad transponder (same charact but different FEC, 5/6) still
does not lock, at least not in 30s. So there still is something fishy.
And the problem is in data search as I can see several CARRIEROK during
the search but each time the data search (I'd guess FEC lock) fails and
after some time the freq is too far away and status becomes NOCARRIER.
I'd be glad to test further.
Bye
Manu
