hi!
 
anybody asked at ŧwinhan or Technotrend for chip details?
Aren't they cooperative?
 
 
kind regards

I thougt Igors patch for high SR is for dvb-s(1) only.

anybody can confirm that dvb-s2 with SR 30000 and Fec 3/4 would now work? Transponders are at Thor 1°W or Hispasat 30°W (Meo)

 Will Manu Abraham merge patches from Alex Betis to st0899_algo.c???

because the lock is much faster and stabile. where without on some channels lock is afther a few minits.

I can provide some logs with and without patch.

Cheers.

Hi All!

  I tried a few variation, but without any success:

  I try to lock (stable! :)) on our new transponders at Amos 4W:

10,723(V) GHz, DVB-S2/8PSK, SR:30000, FEC:2/3, MPEG-4/Conax
10,759(V) GHz, DVB-S2/8PSK, SR:30000, FEC:2/3, MPEG-4/Conax
10,842(V) GHz, DVB-S2/8PSK, SR:30000, FEC:2/3, MPEG-4/Conax

with a TT3200 card + Debian etch with 2.4.24 etchnhalf kernel + the current V4L-DVB mercurial drivers compiled.

  The drivers recognizes my card, and for example it works good with Premiere's S2 transponders at Astra 19.2E. 

But it won't lock stable on our Amos's transponders.

  FYI: on these TP's there's a pilot signal and rolloff set to 0.20. I tried to push these parameters to scan-s2 and szap-s2, but scan-s2 sometimes lock and sometimes won't on these transponders and also szap-s2 (after a few try to lock with scan-s2 and get the channels.conf from these transponders) sometimes locks, but it's not stable, it lost lock after a few seconds.

  What I recognized also: if i run szap-s2 on our transponders it gives me the status message lines much slower than on other TP's.

it almost always looks like this:

/usr/src/dvb/s2api/szap-s2# ./szap-s2-thome.sh
reading channels from file '/root/.szap/channels.conf'
zapping to 1 '1':
delivery DVB-S2, modulation 8PSK
sat 0, frequency 10723 MHz V, symbolrate 30000000, coderate 2/3, rolloff 0.20
vpid 0x00b3, apid 0x00b1, sid 0x00b4
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
status 00 | signal 00b1 | snr 0000 | ber 00000000 | unc fffffffe |
status 00 | signal 00b1 | snr 0000 | ber 00000000 | unc fffffffe |
status 00 | signal 00b1 | snr 0000 | ber 00000000 | unc fffffffe |
status 00 | signal 00b1 | snr 0000 | ber 00000000 | unc fffffffe |
status 00 | signal 00b1 | snr 0000 | ber 00000000 | unc fffffffe |
status 00 | signal 00b1 | snr 0000 | ber 00000000 | unc fffffffe |
status 00 | signal 00b1 | snr 0000 | ber 00000000 | unc fffffffe |

but sometimes it can lock, very rare...

please, help me.

thanks,

Basq
