NextPVR on Armbian missing a few channels

[billybo8]

I have a dedicated Beelink Android MiniMX iii v2 with 2G RAM running Armbian with a manual install of NextPVR and everything seems to work really nicely.

I have an XBOX TV Tuner installed and tuned to UK WhitehawkHill transmitter. It is line of sight and good signal.

Frustratingly I am missing a few odd channels from a couple of mulitplexes. Quest, Quest +1 are two I can think of. The original channels lists for Whitehawk were completely out of date so I made my own channel list from the current information on the UKTVfree website. The text is shown below. I have tried every aerial in my loft and on my roof. I have several to save splitting the signal. Nothing changes the total of 79 channels discovered. I have also tried another DVB-T tuner without DVB-T2 and it just finds the same non-HD subset of channels.

I have looked at the logs while tuning and there are no errors. Does anyone have any ideas for anything I could try to fill in the missing channels please? Is there any way of doing a full scan in case my file is to blame?

You shouldn't have needed to do a manual install, the deb installer should work on Armbian. I have tried on several boards.

In any case I would create a conf file with a single frequency that you feel should work and do a manual scan to see if the signal locks.

dvbv5-scan single.conf

Because NextPVR doesn't unlock digital tuners after they are loaded on Linux, you probably need to stop the server to do this.

You did not attach the zipped set of log files generated from the web app Settings page button. (Yes, you need to zip and attach the complete set of logs--not just a subset that seems to be relevant.)

Sorry couldn't see how to attach logs but found it now.

Also, Martin, my wording was wrong I did use the deb installer. I mean't it was not running in a container or other, just plain linux.

I will look into a single freq scan.
