We use the TBS 6984.
When the produce scan-s2 in DVB-S2 (8QPSK), the card does not lock and get the following dmesg:
[ 237.936495] TurboSight TBS 6984 Frontend:
[ 237.936496] tbs6984fe - modulation 6 is not supported

driver last
Thanks

Hi

Would you mind tell us which parameter you are use to lock S2-8PSK TP.because if you use wrong parameter you can lock S2 TP.

Thanks

Re: modulation 6 is not supported

Postby tombgp » Tue Nov 15, 2011 5:23 am

Additionally, I couldn't compile scan-s2:

Code: Select All Code
root@dvb-s:~/tbs/scan-s2# make
gcc -I../linux-tbs-drivers/linux/include -c scan.c -o scan.o
In file included from scan.c:48:0:
atsc_psip_section.h:57:1: note: offset of packed bit-field ‘reserved2’ has changed in GCC 4.4
scan.c:52:2: error: #error scan-s2 requires Linux DVB driver API version 5.1!
make: *** [scan.o] Error 1


So i tweaked the scan.c:
Code: Select All Code
#if DVB_API_VERSION != 5 || DVB_API_VERSION_MINOR != 1

to
Code: Select All Code
#if DVB_API_VERSION != 5 && DVB_API_VERSION_MINOR < 1

And it compiled fine.

This may be related to the problem above,
I will be appreciated for any help in resolving this problem
Thanks
Tom

TBS6984 haven't got blindscan hardware. Try to complete AUTO AUTO AUTO with real parameters
For example:
Code: Select All Code
S1 11760000 H 26670000 7/8 35 QPSK


Best regards.
