New NS2000 (NS3 / NS4) thread

[Analoguesat]

For various reasons I have removed the previous NS2000 (NS3 / NS4) discussion from the forum.

However this is an interesting topic & there is no reason why the reception of signals & the technical aspects of this transmission format that are from publically available information cant be discussed. As usual, in accordance with our forum rules any discussion must NOT include illegal decryption of encrypted services. Also there must not be any requests for access to streams. Anyone asking for access to streams will have their forum account terminated

Eutelsat 7E, around 10990-10995 vertical, very large transponder (about 40 MHz).
Possible NS4? Or DVB-S2X? Detected now (October 24th 16.50 GMT, 2.4m dish).

Before I try to get the new topic off the ground with a few screen grabs I wish to express my gratitude to our former member who did years of pioneering hobby dx'ing on this subject.
Without that huge previous contribution to the forum we would all be in the dark as regards NS3/NS4 modulation.


Moving on, I found an interesting NS3 mux today that was FTA.
I am guessing that it might be a UEFA Champions League mux from the APID's and VPID's that are prefixed with "UECL..."

For now, in the spirit of the previous topic I have edited out some of the signal parameters from the two screen shots attached below
However, if other forum members are willing to come along and share their screen grabs and include signal parameters I will do likewise.

Today's NS2000 menu screen shot was taken from the demodulator line monitor as viewed via a web browser conecting to the demodulator local IP
Today's signal analyser screen shot was obtained using an NS2000 demodulator connected directly by ASI to a TBS 690A card in a PC.

Sorry, wrhong frequency. It was around 11090-11095 vertical.

Moonbase, I really do not understand the usefulness of such report masking both main parameters (frequency and symbol rate).
Maybe someone does not like that such frequencies are pubblished, but if so, it seems a totally unuseful report.
I know that no one has Novelsat decoder, but if so who could appreciate this?
Just a question, nothing against you Moonbase!!

No worries about your feedback, people have different opinions about this stuff.
There are some forum members who do have access to an NS2000 demodulator, there was obvious proof of this from posts made in the previous topic.

There were two reasons why I did not publish the specific frequency details , they are listed below.

1.
It was generally accepted in the previous NS3/NS4 topic that some frequency details were not published by the main poster and topic starter, I was respecting this trend.

2.
Although the previous topic contained many screen shots of NS3/NS4 frequencies and channels, almost 99% of them were from one contributor and there were a very small number from myself.
As far as I can remember and without going back through the entire topic I cannot recall any screen shots uploaded by other members. There might have been some but I would need to go through the topic to check.

If I see other members uploading screen shots to this new topic and they include frequency and SR details then I will do the same, I said this in my post above.
For the new topic to become useful, it needs input from those members who have access to an NS2000 demodulator to start sharing information and that includes sharing screen shots.

I dont see that the exact transmission parameters really matter - the vast majority of hobbyists will never have access to play with this kit or these transmissions so its of academic interest.

What IS really interesting personally is seeing what is out there for the lucky few folk who can decode these signals, either through their work or because they have invested in Novotel decoders AND have the technical knowhow to set them up & get something out of them.

 

[7mdish]

Yes I understand, and it is a good point to respect the trend of previous discussion.
And I know that someone have access to this receiver, no doubts.
So do I for a very short time recently. And I hope to gain more chances to play with it in the future.
My point was just to complete a good and really useful report, and everyone having access could make some test.
But this is the trend.... well, respect by me.
Maybe we could add at least the satellite in our reports.

Sure, I will include the satellite in the next similar report I upload.

 

[Analoguesat]

One point i will make - if anyone has access to one of these decoders through their work, or you work for / have a contact within one of the uplink companies be careful what you post. If you have bought your own kit then its fair game, because its no difference to setting up a satellite receiver & chasing down feeds like many of us do on our kit.

Scanned few channels on 7e and 10e
11387v 10e
11429v 10e
11222v 7e

11221h 34286 in 10e now changed to 35295

Also, something is at 10e for quite a while but i never pay much attention to it 12465v 41950. No stable lock with usb card, thus may be acm/vcm, data or NSx. Is not listed in flysat as well.

@tom55,

Thank you for sharing your scan results, nice contribution to the topic.
I can confirm that the two screenshots I uploaded in reply 3 of the topic were taken from the frequency on 11222V on 7.0 East that you scanned and that it was using NS3 at the time of my tests.

Possible NS4? Or DVB-S2X? Detected now (October 24th 16.50 GMT, 2.4m dish).

Although you changed the frequency range to 11090-11095 in a later post, I found something at 10995V on 07.0E with narrow bandwidth.

There is something around 10994V to 10995V that fails to lock in a DVB-S2X receiver (Octagon SF8008) and fails to lock on both EBSPro and CrazyScan.

CrazyScan registers the signal but fails to lock it.
At the moment I dont know for sure that the frequency has NovelSat modulation, just guessing based on the fact that it "Syncs" using NS3 mode.

I have attached below the screen grabs from NS2000 demodulator, Promax Ranger meter and CrazyScan.
The frequency will "Sync" in an NS2000 demodulator but it fails to lock, possibly due to incorrect SR. I could try stepping the SR in small increments to see if I can get it to lock.
However, if @tom55 is around and can scan an accurate SR for the frequency I would be grateful as it would probably speed up the process.

I agree that anything related to the decryption of TV programs or applications that decode them should be banned. Still, I'm a little upset that even the parameters of satellite reception are thought taboo, as if they hurt the interests of some manufacturers of receiving devices.
Why this restriction when it comes to satellite reception parameters? I understand that military service reception is not even a topic to be discussed, even if we could find information about it. But when it comes to the reception of feeds of any kind, which led to the creation of this niche community, it seems to me that it is an exaggeration to limit the curiosity of some enthusiasts to avoid harming the interests of some commercial manufacturers, such as Novelsat. And I ask, how would it harm these interests if we wanted to know, as a previous colleague says, what symbol rate is used for a Novelsat frequency because we will not be able to see that feed anyway, not having that device? Maybe I'm wrong, but it seems that this parameter is a kind of Achilles' heel through which, supposedly, we could learn exciting details about the transmission, especially how to find the technical solution to find and lock the signal. And then...?
I understand Novelsat likes to be secretive when it comes to its equipment. And to some extent, I know those who have this device and are unwilling to answer all our questions about this device, but this should not make us schizophrenic because a manufacturer wants to keep its "secrets." They have no choice but to do so, but they can't stop our desire to learn and to know everything that is going on with the reception technique. Isn't that why these niche forums, like this one, are there?
What the heck? We are on a forum of reception enthusiasts and not on the manufacturer.

 

[7mdish]

I suspect the problem is not Novelsat or any other manufacturer, but some well known broadcasting companies.

I confirm that it was around 11090 GHz, but that signal gone just after my posting, and I was not able to lock any possible TV or data broadcast.

Update:

Following on from post 13, I stepped the SR and found that the frequency around 10994V-10995V on 07.0 East would sync but not lock between an SR range of 5708.4 and 5711.4 which gives a mid point SR of 5709.9
Perhaps the carrier is empty at the moment and it might lock later? Or, it could be the stability of the LNB and dish size preventing a lock? There are a few variables.

 

[moonbase]

Thank you for your feedback.

It is quite old, not been updated for a couple of years.
What version is installed in the unit you have access to?

 

[moonbase]

...What the heck? We are on a forum of reception enthusiasts and not on the manufacturer.

Check my post 13, it contains screen grabs that present satellite, frequency and SR details.
