Problems scanning

Chris Coles

Hello

I am new to tvheadend; and I am having some problems.

The location is in the UK, Lancaster (North West).

Hardware The card is Hauppage WinTV-HVR-5525

https://www.hauppauge.co.uk/site/products/data_hvr5525.html

The aerial is: SV9460
https://www.oneforall.co.uk/tv-aerials/sv-9460-amplified-indoor-tv-aerial#/step-1

(Enabled as a LNA enabled in parameters)

I am using a docker container in UNRAID, with a driver /dev/dvb/adapter1 [Silicon Labs Si2168 #1 DVB-T #0]
I have disabled DVB-C and DVB-S currently in Configuration > TV adapters.

It is intended to be eventually used for Kodi, once setup.

Problem

Using the pre-defined mux UK - Lancaster; I pick up no channels at all, I get six Muxes's and Force Scan.

When I use the default-auto predefined; I get a considerable more amount of fails but it does pick up about 50-80 services from 57 muxes.

I have noticed there are no DVB-T2 (HD channels) - both the card and aerial which I think has good signal is not picking anything up.

Last night I spent a few hours trying to update the frequencies (using a site I found), putting stuff in AUTO and setting 8MHz, even trying to adjust the QAM/256 etc. I did not get very far at all...

I probably made myself more confused as the Freeview website suggests Winterhill mux not Lancaster for my post code. I believe my aerial is in the direction of Whitehill, and I tried with LNA on and off

I set the networks to advanced options: New muxes + changed muxes.

The DVB-T channels I do find seem strong and very clear - BBC, Dave, SkyNews etc - perfectly clear, sharp, no audio/video cutout.

It be great if someone can help me, possibly give step by step or basic instructions especially how to get DVB-T2 HD in my area.

I sort of hoped it would be a case of hitting go and it do all the work.

Thanks
Chris

The DTV scan tables supplied with TVH are notoriously unreliable, but in the case of the Lancaster relay they do appear to be correct - or at least they agree with https://ukfree.tv/transmitters/tv/Lancaster

If you are receiving the Lancaster relay BBC1 should be on 521.833MHz and Dave on 530.167MHz. The one HD mux available is on 474.167MHz.

I suspect that your indoor aerial is not receiving enough signal for the HD mux.

Thank you Dave

That was the website I found last night and I couldn't be sure it was working or up to date (more difficult when your working with a incomplete picture of what a good scan looks like).
I've realised my general scan auto is picking up services on
* 538MHz
* 554MHz
* 562MHz
* 578MHz

They are all winterhill frequencies.

I also tried the 3 frequencies you mentioned (I know they come up in Lancaster pre-defined but I did a manual addition but with different settings QAM/auto and same Auto settings as the four above just changing the frequencies and it failed too)

I think your right now, that my indoor aerial is not able to pick up the HD and the less powerful Lancaster transmitter (that surprised me).

Thank you for your help.

I now need to sort some long leads out to the loft.

Once I've tested it, hopefully mark the post as solved.
