I have compiled the driver for my Geniatech T230C DVB-T2 USB receiver according to https://www.linuxtv.org/wiki/index.php/Geniatech_T230C and it seems to work. But when I try to scan for channels with TVHeadend 4.0.8 on my Raspbian Jessie system TVHeadend reports:

:
2017-04-06 02:22:34.000 mpegts: 706MHz in DVB-T2 - scan no data, failed

:

Only 3 SD channels but no HD channels are found. With http://www.dvbviewer.com/de/ I could receive all HD Channels in good quality on Windows 10.

What could be the problem?

Could the version of TVHeadend be too old?

I managed to perform a re-scan by shutting down tvheadend (on debian/ubuntu service tvheadend stop), removing the usb tuner, counting to 10 :-), inserting the tuner, starting tvheadend and tailed syslog until it had finished scanning. After that, I had to go back into the UI and selecting configuration | DVB Inputs | Services | Map Services -> Map All Services. I then had all my services back (in their new positions). Just a matter then of deleting all the porn and sales channels :-)

  • by 'deleting' I mean un-ticking the 'enabled' box in the channel viewer. I also disabled the channels that were not mapped correctly. I had to wait until after 7pm to do a re-map as I realised that BBC 4 wasn't in the list (it doesn't start until 7pm.) – Cwissy Feb 13 '18 at 18:26
