TBS6281SE DVB-T not tuning.

[Drifting]

Hi
Have fought long and hard to install the drivers for this. Thought all was well? Seems not. As you can see below the card is seen.

No please bear in mind I have just followed the instructions on here, and one other site. And am now at a loss. Thes signal is fine, the TV next to my Mythserver has 100% signal, even went so far as to take the aerial out of the TV and plug it in direct to the card.

Any suggestions welcome, as I am at a complete loss.

Kindest Regards

Paul.

Hello
1)please check the signal cable if connect to the RF in port or you can try those two port.
2)Try to use other application , such as dvblast .

and BTW. Our cards do not support the active antenna, it cannot supply the power for the antenna. only support passive antenna.

Best Regards

Tried both, neither worked.

2)Try to use other application , such as dvblast .

Sorry I have no idea how to use dvblast, being partially sighted the instructions are horrendous! If you can advise how, I would be happy to try.

and BTW. Our cards do not support the active antenna, it cannot supply the power for the antenna. only support passive antenna.

I am using a standard digital passive aerial / antenna for the UK

Any other suggestions?

Kindest regards Paul.

You use old scan util (from dvb-apps package) with mux list in new format for dvbv5-scan util from v4l-utils package. Mux list just can't be parsed

P.S. For DVB-S2/T2 scanning better use scan-s2 with old mux list format.

Hi Crazycat
I don't want to seem ungrateful.
But all that meant nothing to me! I am not a programmer, or that experienced in Linux. Would it be possible to explain in more detail first how to get scan-S2 as the link on the page for it does not work. If I need to compile it? then that is beyond my knowledge. However I got this far by following instructions.
As I said, Myth could not tune either, which is why I wondered if I had done something wrong with the install?

Kindest regards
Paul.

[crazycat]

yes, need compile scan-s2:

Code: Select All Code

git clone https://github.com/crazycat69/scan-s2
make
sudo make install

Hi Crazycat

Now have the scan-s2, thanks for that.

Still need a bit of hand holding from someone on how to use it to test UK DVB_T tuning.

Thanks Paul.
