I hadn't used it for ages, screenshot I showed earler with the dBs came from it, but trying today I can't tune any channel I choose from the spectrum. No Idea why.

I'll do it this way (tomorrow now) with the debs here -

Bitbucket these include v4l-updatelee and updatelee.

If no go, I'll do it the long way, building from scratch. I'll let you know how I get on.

The updateDVB on Bluzee's Bitbucket version is not much use - it give percentages instead of dB's. Furthermore it doesn't even show the mux frequency!

I'll try and find the version I originally used. I suspect that was the one I built with QT - Bitbucket

@statalite
I have sourced the latest updateDVB binary which I can find that has dB values that vary according to signal quality whilst on the chosen channel.

If you have the three udl debs installed already in your distro (udl · master · bill murphy / kernel-dvb-pkgs)

You just need the updateDVB deb

wget hxxps://bitbucket.org/majortom/updatedvb/downloads/updatedvb_1-1_amd64.deb (live link, so change xx to tt)

sudo dpkg -i updatedvb_1-1_amd64.deb

If when you double click on updateDVB in Applications and nothing happens (as happened with me), you may be missing a couple of library files. So -

In Terminal: ldd ./updateDVB | grep "not found"

may show any missing libs. If so, sudo apt-get install them, and you should be good to go.

The Blindscan for T/T2 doesn't do anything for me and Spectrum Scan is not available in the menu. You just click on a mux frequency on the Spectrum graph (doesn't have to be spot on the intended frequency), and it will bring up the screen to show the program numbers being found, and dB values.
Click on a program and then the Play button. VLC wasn't playng for me, so I obtained mplayer from Synaptic package manager and changed vlc for mplayer: To change in UpdateDVB, click on File-Settings-General, and in there, change vlc for mplayer in /usr/bin/vlc /dev/dvb/adapter.

Snap. I have problems too with updateDVB on the PC it's currently on. So - a fresh OS to install.

Thank you very much for your efforts, I will give this a try this evening and will report back.

Ok first time I didnt install the DEBs, thought I would already have them clearly not.
First time i downloaded and dpkg but no program, so went to install DEB, said broken package, so removed updateDVB broken package using package manager.
Installed the 3 DEBs / making sure they were installed, downloaded again updateDVB, this showed in terminal this time as Saving to: ‘updatedvb_1-1_amd64.deb.1’
then adjusting sudo dpkg: sudo dpkg -i updatedvb_1-1_amd64.deb.1 (Reading database ... 366642 files and directories currently installed.) Preparing to unpack updatedvb_1-1_amd64.deb.1 ... Unpacking updatedvb (1-1) over (1-1) ... Setting up updatedvb (1-1) ...
but nothing no updateDVB in the start menu, nothing in applications, nothing? Can you help?

Is this a new distro install? You may need to update the kernel.

sudo apt update

Then some dependencies

sudo apt-get install git build-essential subversion libgl1-mesa-dev mesa-common-dev libqwt-qt5-dev

If it's installed it will be in /usr/bin

 

[Llew]

Sorry, /usr/local/bin

 

[statalite]

Sorry, /usr/local/bin

It is there, loaded updateDVB, setting up as before but no spectrum again, behaviour as before, lack of options.

 

[Llew]

What happens when you place your cursor anywhere on the spectrum graph? It should show any frequency depending on where you have the cursor. As in my screenshot

It gives coordinated in green colour.
No graph like I said.
If I click on the exact frequency it searches an locks and does display.
If I blind scan it does not pick up the T2 muxes (Regardless of QAM256), but it does pick them up if I use the spectrum way.
dB is shown as per screenshot but no (QAM Auto, just a test), strength percentage (I shouldnt worry about?)
Thank you.
Any Idea's on why no graph or T2 on blind scan?

 

[Llew]

Should show strength (see my screenshot). In Menu, I had DVB-T2 and Qam Auto. Doesn't seem to matter what you have there though.

Blindscan doesn't work for me for some reason.

I'm not sure if strength will tell me anything more than dB.
You say you had to go to the older version to get dB? Mystery as to why the developer would remove this, I wonder if newer version for me would make everything work, but as you say maybe no dB scale.
Odd that blind scan doesn't work for you but graph does.

It's a project originated by Chris Lee and carried on by two or three guys on the US site Rick's Wildfeed forum. I hesitate to send members over to other forums, but as there is an updateDVB thread there that may well be of interest and where they may well be able to answer anything more technical than I can offer at the moment, you may find it interesting to check the thread in the Computer section there.

Going back to your original post, is the app going to be of any use for checking your aerial etc?

Yes it will satisfy the original requirement, thank you.

I just wanted to thank you once again, I used this as intended, it helped me test my signal before relocating my bracket. It's given me enough usable signal (around 30db) and has stabilised my reception.

Glad it's of use. Just added a T/T2 USB stick to my Raspberry Pi UpdateDVB version, and it has the Spectrum tab for doing a scan. Blindscan too.

Stupidly I wiped my drive and forgot about this software.
I need to re install it again for myself and to help a friend out, for the life of me I cannot get it going again.
I have been over this thread more this than I have had hot meals.

So far I have installed the pre-packaged updateDVB DEB, updated the dependencies.
It asks before this to install kernel 5.4.2, I try to install these 3 DEBs

linux-libc-dev_5.4.2-udl-1_amd64.deb
linux-headers-5.4.2-udl_5.4.2-udl-1_amd64.deb
linux-image-5.4.2-udl_5.4.2-udl-1_amd64.deb

but it says its already installed, when I try to change to use this it only has 5.4.0 and 5.8.0 in my list.
I am running Mint 20.
Idea's welcome.
