I found it almost impossible to get a lock on Radio Gdansk and the others using 405ks/s were very hard with CS. These captures were using a software demodulator from the Amsat-DL forum. It's not the easiest thing to use but has interesting possibilities: https://forum.amsat-dl.org/ind…ftware-dvb-s-demodulator/

Just had a quick scan, and it does appear Radio Gdansk on 12590V has indeed gone.

Scan von heute in untere band
in bereich Niedrige SR
anscheinend hat es sich nicht geändert
Scan from today in lower band
in the area of low SR
apparently it hasn't changed

Not the signal that I expect ...may be one day

Another test for low symbol rate reception on the upper band at 16.0E with IQmonitor and Crazyscan.
I must add that I manually locked these transponders with both applications.
On this occasion, I managed to lock the low symbol rate on 12689 V,146,3/4, Radio Gdansk, which I had not managed before. Although the signal is stronger on this one, over 18dB, locking it is more difficult with Crazyscan. The Head codec (I have not heard so far) is used for Gdansk Radio.
Probably the local oscillator of the lnb dro IBU is affected by the high temperature outside.
Not sure if there are 4 trps active at 12577 H,405,3/4, or only three. IQmonitor found four(?!)

Hallo ,
nach dem erfolgreichen Ergebnis von satesco habe ich selbe rin diesem Bereich probiert.
Ich wollte alles automatisch suchen lassen ( mit df 10)
IQMonitor Pro hat nur drei sr405 gefunden , von dem vierten keine Spur , vielleicht am Abend
ist es abgeschaltet ? ich weiss es nicht.
After the successful result of satesco, I tried the same in this area.
I wanted to search everything automatically (with df 10).
IQMonitor Pro only found three sr405, no trace of the fourth,
maybe in the evening it is switched off? I don't know.
После успешного результата сатеско, я попробовал сделать то же самое в этой области.
Я хотел искать все автоматически (с помощью df 10).
IQMonitor Pro обнаружил только три sr405, следов четвертого нет,
может вечером он отключается? Я не знаю.

On this occasion, I managed to lock the low symbol rate on 12689 V,146,3/4, Radio Gdansk, which I had not managed before.
I can lock 12689.2 V 146 via CS blindscan and TBS 6903, but I´ve tried to lock it yesterday evening in manual - no way yet...
-
nach mehrere Versuche, hat IQmonitor pro
mit dem Automatischen Blindscan ( DF9) geschafft ,
die Frequenz 12588,75 sr 146 zu finden und zu locken
After several attempts, IQmonitor pro
with the automatic blindscan ( DF9) managed to find
and attract the frequency 12588,75 sr 146.
После нескольких попыток, IQmonitor pro
с автоматическим слепым сканированием (DF9) удалось найти
и привлечь частоту 12588,75 sr 146.

Finally I managed to lock 12689 V 146 CS in "manual" and TBS 6903 - it´s seems difficult for my setup.
The other three ones in horizontal - only via manual scan with CS - but without lock-problems.

Surprisingly, the 6903x card worked best with a low symbol rate (405 Ks) at 16.0E with the neumoDVB app on Ubuntu.
Then, again a reward for me, Crazyscan locked those trps with 405 Ks which I had failed on other occasions.
And about IQmonitor I can say that it works very hard and is unreliable when auto searching/blindscan. The best you can do is manually lock 12577 H/12578 directly without any search.
I don't know which of the IQmonitor versions can work well with the 6903X card.
The above comments are not intended to diminish the merits of one application over another, especially regarding 6903x. But I must add that Deeptho, the developer of neumoDVB, has put a lot of time and thought into making this card perform better on Linux than it does under Windows.
-
I kindly ask you to do the following experiment for me, which I cannot do myself due to the lack of TBS 6903X:
For all three programs, install
16°E polarization H
Fstart = 12575
Fstop = 12580
with the same spectrum size with the axes of frequencies and signal strengths visible in the screenshot (the same as for IQmonitor Pro);
For IQmonitor Pro, register the RF spectrum in 1MHz steps, and then run the HR spectrum with the Add checkbox checked.
Please do not skip frequencies while running the program.
I ask you to make a screenshot with the left button so that both the spectrum and the main program window with search parameters can be seen on it. Save the spectrum and transponder table and attach it to the report.
For Crazyscan in the same format and spectrum size as IQmonitor Pro, acquire the RF spectrum at maximum resolution (minimum frequency step) and then execute BlindScan. Take a screenshot of the entire program window so that you can see the frequency step. Do not crop from it when posting.

Thank you in advance

-I hope I didn't miss something important in the tests required.
BS IQmonitor with 6903x card between 12575-12580 H took almost three hours with 1MHz step. Only one trps found and locked it,12576,5 H. The result is seen in the screenshot. Strange is that although the feed didn't show any parameters, I had a stream with TSReader.
(I would like to know if there is an IQmonitor version that scans faster?)
-Because CS does not support scanning less than 10 steps, I had to extend the bandwidth by a few units.
At 0.1MHz step and high resolution, Crazyscan couldn't find these close transponders with low symbol rate. Only manual search could lock them.-In the case of neumoDVB you can't set the steps in blindscan. I asked the developer to tell me how to choose, but he didn't say anything. He said that they are implemented in the search algorithm, which he set so that scanning with 6903x is faster.
And indeed scanning with this card takes less time; it's much faster than any such application under Windows.
In fact, these low sr muxes do not appear on the spectrum, which is why they can't be found in blindscan. Only manual search can find and lock them.

Thank you very much for your hard work.
First, I will answer your question about scanning speed - there is no such version of IQmonitor Pro that would work faster.
And now I'm sure it won't. The fact is that the bundle of the TBS-6903X driver and the StreamReader of the respected Crazycat are not "friends" with each other, since the latter does not have complete documentation on the driver and card registers.
The Linux driver seems to have the same problem.
At least the spectrum you got has nothing to do with the scan results shown at the bottom of the screenshot.
And here, apparently, everything rests on the lack of complete documentation for TBS-6903X.
In order not to give the impression that your work is in vain,
I want to share with you an important result of the analysis of RF spectra from your excellent video.
The receiving setup on which the spectra were obtained has a very low cross-polarization isolation (only ~10dB instead of the usual ~24dB).
The news, which would seem not the most joyful, but inspiring optimism, is that with the correct setting of the LNB rotation angle and compensation for cross-polarization interference, the sensitivity of the installation will increase, and the SNR for some transponders will increase by 2dB.
You can make this fine tuning using the dynamical (real time) spectrum in the IQmonitor Pro program.
Health and success

heute findet die automatische Suche in diesem Bereich nur noch 12569 H.
Andererseits werden viele Frequenzen im manuellen Modus mit mehr als 80% gefunden.
today the automatic search finds only 12569 H in this area.
on the other hand many frequencies are found in manual mode with more than 80%
сегодня автоматический поиск находит только 12569 H в этой области.
с другой стороны, многие частоты находятся в ручном режиме с более чем 80%
