I saw something interesting on another forum, and seeing as I can't get 30°W here (blocked by trees) thought I'd ask.

Can anyone pick up anything on Hispasat 30°W 11492V with a multistream capable DVB card? The symbol rate is listed as 7522 and modulation as 8PSK with FEC 8/9.

It seems to be implied that this may contain a feed of the Portuguese digital terrestrial multiplex in multistream mode, but that the PLS code is unknown.

I've run those parameters (DVB-S2 8PSK/SR:7522/FEC:8/9) through an online bitrate calculator and it comes back as ~19.9Mbps, which would match the bitrate of Portugal's only DVB-T multiplex!

TBS tuner can see something. 12.9dB. Can't lock it however. Any idea of whether it's Root or Gold and I'll leave it running over night?

Not sure! The information I've seen is very sparse unfortunately. I guess root is most likely judging by the other multistream channels (I've only seen French ones running gold) :-)

I've left it auto searching in root mode for the PLS code... Here goes nothing.

Also if anyone wants to join find the PLS code you're more than welcome!

Could you post a link of the discussion?
I wonder how the exact modulation parameters incl. FEC can be determined if the PLS is unknown. If your calculated bit rate matches the rate of the terrestrial mux multistream is not required ;)

Yes sure :-) - h**p://www. sat-universe.com/showthread.php?p=1256988 (Post #22 onwards)

Flysat also lists those parameters.

I see what you mean though! Maybe someone has found the PLS.

I guess they might want to multistream it anyway even with only one stream to prevent standard receivers from getting it if it is Portuguese DVB-T as these channels (RTP1, RTP2, SIC, TVI, ARTV) are encrypted for Meo and NOS.

The link doesn't point to the thread.

The parameters are outdated (from May posted by @EnoSat) and no PLS mentionend :rolleyes:

The link should work; I just put a space in it after the www. to stop it parsing on here.

This frequency has reported for 1 year ago already, there are no PLS code for this stream, the problem is the Pilot and something else...
The active PID is 515
When you have a PLS code the SNR is weak until you find the correct code.

If I'm wrong please, let me know.

btw, @30°W there are also another hard TX to get: the Spanish DTT on satellite (11222 V, 10810 H, etc, all the Abertis TXP)
They use an unusual way for their TX , all PIDs are encrypted (PAT, NIT, PMT, etc) worse than the BBC at 27.5°W.

Good luck

Yes, I've managed to watch the Spanish DTT Abertis feeds before with a little Python script I wrote (and the correct keys). The PIDs which look like just data on those transponders are actually a full DVB-T multiplex transport stream encoded in BISS.

The structure of them is similar to the Italian RAI multistreams with La 2, 24h and Clan on one PID then multiple regional versions of La 1 on the other PIDs. Then the commercial multiplexes are there too as well as a couple of the regional public ones and very low bitrate versions (around 3Mbps) of a few of the regional channels that don't pay for their whole multiplex to be uplinked and are just on there for TDT sat receivers I guess! (Like TV3)

What does this mean? Is that the DVB-S2 pilot? Does it do something to stop the signal locking then?

Thanks for the interesting information!

..that can be anything ;) Maybe it's not DVB-S2 at all..

Yes, any PC card should work for the Spanish channels (they're normal DVB-S2 transponders),

You need a PC running Linux (I use Ubuntu), VLC Media Player, The dvbstream package, the BISS keys, and maybe TVHeadend depending on how you want to watch the channels!

OK so this is a strange one! I've noticed myself before that there's something unlockable on 11493V on Hispasat, but never really done anything about it. Having noticed this thread i'd thought i'd try to find the PLS code. I left CrazyScan searching for a few hours while i went out, and to my surprise it had a hit when i came back! I left it searching using COMBO (instead of ROOT or GOLD), and got the following.
11493V SR 7523 FEC 8/9 PLS code 2388.
I streamed this to 4T2 content analyser and there is a package of 4 TV channels and 7 or 8 radio channels.
The strange thing now is if i enter the found PLS code directly into CrazyScan, it won't lock! Even tried it on DVBDream and a couple of other programs, no lock!
So i'm going to leave it searching again and see if it reports the same PLS code, or whether it's changing on a regular basis (which would probably explain why it's not been reported as yet!). If i manage to lock it again i'll post some screen grabs!

So I can confirm the PLS code is 'COMBO 2388' although i still can't get it to lock by entering it directly. I use the 'search PLS code' function on CrazyScan, but enter a starting number of 2385, and it locks when it gets to 2388. I've attached a couple of screenshots.Capture1.PNG Capture2.PNG
