Hi,

is there a magic how to reliably start and operate Scan&Tioune?

I need one reboot to be able to start the program. To start, close and start again is not possible. The non-movable information window appears and stays for several minutes, then it closes and nothing more happens.

When I get it started, I couldn't get something catched and/or decoded. The scanning arrow runs from left to the right, but there is no spectrum shown (see attachment).

Running an up-to-date Windows 10...

(Don't be bothered by the 0V LNB voltage, it is fed from another part of my reception system. Minitoiune v0.9beta8.9 is running very well...)

TIA.

73, Thorsten

Dear Jean-Pierre,

I'm really excited about both the MiniTiounerProV2 card and the Scan & Tioune software !!

I am using an Asus I7-7700HQ 16GB memory Notebook, W10 update and everything works fine. Every time I see a new carrier I click on it and tune in the new transmission, fantastic.
The MiniTiouner version also works perfectly ...

Compared to when I started with RTL-SDR and DVBS-GUI it's wonderful !!!

I can't wait to try the MiniTiounePRO version .. if I understand correctly it can tune two channels at a time with 2 TS

Thank you very much for the great work you are doing !!

Hello

@dl9sec Thorsten,

Your RF power is too much strong! -4 dBm is anormal, you saturate the Tuner.
(your LNA gain is negative, it works like an attenuator and is not suffisiant...
it should be about -50 or -60 dBm.

Look at my pictures, they show a RF level of -58 or -59 dBm

@Roberto

if I understand correctly it can tune two channels at a time with 2 TS

Yes, the hardware is ready to do dual receiving, but today the software "DualTioune" can receive 2 channnels at same time but only in DVBS mode. I 'm working now onit to add the DVB-S2 mode

Hi Jean-Pierre,

thanks for the reply.
I am not really clear with your answer.

Which LNA do you mean? That one in the MinitiounerPro V2?
How can I influence that gain? There is no part in the "Scan&Tioune.ini" that sets a LNA gain...

Regarding the starting problems of Scan&Tioune...

I am using a computer running Win10 x64.

When i try to start the program and it fails (no obvious error message or something from the program itself), i can find an application error message in the Windows management console:

I suppose, that the 32Bit Scan&Tioune isn't redirected to the correct ntdll.dll.

Then i tried to activate the compatibility mode for the program. Windows suggests a "Windws 8" mode.
In this compatibility mode, Scan&Tioune starts.

Nevertheless, the program neither tunes e.g. to the beacon, nor does a scan result in a spectrum with stations.

Here is the info output:

Again: My hardware works fine and Minitioune v0.9beta8.9 does a great job so far...

Any ideas?

Hello Thorsten,


Seeing the screenshot, Scan&Tioune is working normally.
But you have something bad in your environment:

The LNA gain is negative!
this LNA is a chip inside the NIM, 1st stage before the tuner, that has a gain that can vary to amplify or attenuate a signal, to try to give a -20dBm signal to the tuner.
Normally the gain that is shown is between +6 and +13dBm .
on your station I see a gain negative of -10.1 dBm !!
But on the scanner I see no signal, on the RF level I see no signal (-107dBm)

That signifies that you must have a QRM, a very High signal that is sent to the NIM. this signal can be far from the frequency, the LNA is wide band and the tuner input 10 MHz wide.
so, I am sure that you are sending a very high level signal in your cable ( 144 MHz??, 435 MHZ ?? or ???) that disturb completely the NIM : as a very high signal is at the input, all AGC stages inside the NIM lower all levels at the max they can, so you see nothing on the spectrum and you offset up the spectrum display to see only the noise floor of the NIM



You can try to scan using a bandwidth of 60MHz, perhaps you will discover the strong signal disturbing your rx.

Your Answer is not plausible for me.

How can you explain that with exactly the same hardware configuration Minitioune v0.9beta8.9 works as expected?

There must be basically a big difference between Minitioune v0.9beta8.9 and Scan&Tioune...

@Jabi:
Photo are saved in the Minitioune directory.

@DL9sec:

on the Minitioune screenshot the LNA GAin is positive and normal : +8,3dB and you have a signal ,RF level is normal : -41 dBm

on the Scan&Tioune screenshot the LNA gain is negative! : -10.1 dB and you have no signal : RF level is -107 dBm

I cannot say more. If you just change the software and don't change anything with the hardware I don't understand. Never seen that.
The Tiouner software part of Scan&Tioune is the same than in Minitioune, so should exactly the same. (The only difference is for rendering the video)

Jean-Pierre F6DZP

When will there be a version for de Express Hardware?

Bonjour Jean-Pierre,

Pour moi fonctionne parfaitement depuis plusieurs jour (1 seul message d'erreur sans plantage)
La vidéo est même plus fluide avec VLC que avec direct-show !
Quelques exemple avec parabole 80cm ordinaire(STRONG)
Le flux vidéo ne semble pas encore transmis sur TiouneMonitor ?







Merci pour ce surperbe développement
