After had a glance at szap.c I assume I understood the config file
format. BTW, the szap I use comes from the Debian package dvb-utils,
version 1.0.1-6
I made the following line in channels.conf:

T-DSLviaSat:10773:h:1:22000:0:0:1:251

Hope this is it. :-/

> Have you tried to tune to other transponders, has this worked?

I tried the following:

- tune to known TV channel (german "Das Erste") with dvbtune:
# dvbtune -f 11837000 -p h -s 27500 -v 1960 -a 1920 -t 9
Using DVB card "Conexant CX24110 with CX24108 tuner, aka HM1221/HM1811"
tuning DVB-S to L-Band:-1073742460, Pol:H Srate=27500000, 22kHz=off

Not able to lock to the signal on the given frequency

Not very promising.

- tune with szap to "Das Erste":
# szap -x -n 1
reading channels from file '/root/.szap/channels.conf'
zapping to 'Das Erste':
sat 0, frequency = 11837 MHz H, symbolrate 27500000, vpid = 0x0065, apid
= 0x0066
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

status 07 | signal c1c1 | snr 0000 | ber 0000ffff | unc 08040000 |

No error messages at least. Exit code is zero.

- tune with szap to "T-DSL via Satellit", using the abovementioned
entry:
# szap -x -n 227
reading channels from file '/root/.szap/channels.conf'
zapping to 'T-DSLviaSat':
sat 1, frequency = 10773 MHz H, symbolrate 22000000, vpid = 0x0000, apid
= 0x0000
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

status 01 | signal 6262 | snr 197b | ber 0000ffff | unc 08040000 |
status 05 | signal d4d4 | snr 26f5 | ber 0000ffff | unc 08040000 |

Ditto.

I don't know how to interpret the output by szap.
Could somebody please help me and give me a hint what needs to be fixed?

TIA, HAND
Holger
