Hi everybody , as a newbie should be very happy to know wich fimware Black Hole is recomended to my VU+ duo ?
(I have now OpenPli 4.0 but have some problems with dvb-s2 8psk tranponder ) so i'll try Black Hole.

Thanks in advance for all help i can get.

Thanks Set_72 i've installed the image "open blackhole 0.6" without problems but still have no signal at the mostly dvb-s2 8psk tranponder, with " S" transponders works well.
I have another STB ( DM800) and that works well with all satellites between Astra 23 and Hispasat 30W......with the same motorized Rotating antenna.
Is there someone as can tell me how to solve the problem ?

Thanks in advance

It would help if you could please provide more detailed information.
Staellites, frequencies and channels you can't scan in.
General location.
Dish size.
Is the dish connected straight to your receiver, or do you use anything else, like a V-Box, or splitter?

There no reason to install 0.6, which was a beta under many respects, instead of the current 1.0 (the file starts from 1.0.009 and then, after you'll have it updated online, you'll get the 1.0.014.

I've tried firmware BH 1.0.009 now and updated online,....... then i tried to download diferents dvb-s2 8psk tranponder between Astra 23 and Hispasat 30W but still have the same problem .... ( have no signal ) . With " S " transponder i've full signal as well.
Is there sameone as have the same problem ?

The only difference between S, and S2 transmissions, is generally the signal quality required to lock in the signal, and the fact that you need a HD receiver to scan in the channels.
You mention a VU+ Duo, which is now an old receiver, and no longer produced, but if genuine, there is no reason why the channels shouldn't scan in, providing you're doing it correctly.
You haven't answered any of my questions, so can you please tell us what your signal quality levels are, on the standard definition channels you can scan in.

If I knew your general location, and dish size, I could ascertain the best channels to ask you to manually scan in, but try Astra 1, 19.2E.
Go into the menu, setup, Service Searching, Manual scan, and enter/select the following.
System DVB-S2
Frequency 10964
Polarity Horizontal
S/R 22000
8PSK
FEC 2/3
Then tell us if any channels scan in.

My location is Stockholm and i use an 1,2 m dish ( with my other STB DM800 i have no problem to to scan all channels ) .
With Frequency 10964 + Polarity Horizontal + S/R 22000 + 8PSK + FEC 2/3
i get 11,50 dB 71% SNR and 0 BER and i got 9 channels
with Frequency S-2 11818 V i got 8 channels
with Frequency S-2 10906 V i got 7 channels
with Frequency S-2 10936 V i got 8 channels

Then i tried with Frequency : 11127 V nothing happen...... 0 channels
11229 V nothing happen...... 0 channels
11259 V nothing happen...... 0 channels
11229 V nothing happen...... 0 channels
11227 V nothing happen...... 0 channels
11436 V nothing happen...... 0 channels
i've even tried with other Satellites and that seems like when i use transponders S-2 with high frequencies it does not work.

I use an VU+ duo with chipset : BCM7335 with 2 Tuner = BCM7335 DVB-S2 NIM ( I think it's the original device )

Are you using a 36v Motor, and a V-Box II, on your dish?
71% signal quality seems low, considering the size of your dish, and location, I would have assumed you'd be on, or near, 98%, unless your dish isn't aligned correctly, or you have a long cable run.
If you check lyngsat, you will find that transponders can be on a different satellite beam, requiring a larger dish, or more accurate alignment, to receive them, especially the HD channels.
Try manually scanning in 11686 V DVB-S 22000.
You can check the channel beams by clicking on the beam link, for 19.2E, they have the Europe beam, Europe wide beam, Pan Europe beam, Europe KU beam, and maybe others:

i can read on the motor manual "Rotor SAT HH100" operating power supply 13 / 18 V.
On the same LNB 0.2 twin has even a DM800 and takes all S-2 transponders without problems

With frequency 11686 / 22000 i get SNR 8,50 dB 53% BER: 0 and i don't have a long cable run thats arround 5 meter.

Thats strange because i have another STB ( DM800) and that works well with all satellites between Astra 23 and Hispasat 30W......with the same motorized Rotating antenna and i can get all S-2 transponders from Lyngsat as well.

The VU+ tuner, at least on my Duo 2, requires more signal quality, than my other receivers, to scan in channels, but once scanned in they will work at a lower quality.
I still think your problem lies with your poor signal quality, and the fact that you can scan in SD channels, at such a low quality, seems to support this, as HD channels are more difficult to scan in, than SD.
You can prove/disprove my theory, by taking your receiver to a friends/relatives house, whose dish provides a better signal quality, and scan in some HD channels, on higher frequencies.
If it then works I would check your cable, for any damage, or signs of water ingress, check the connections, and check your LNB.
Other things you could try is checking your Latitude, and Longitude, are correct, and entered correctly, in your receiver, if using Usals.
Switch to Diseqc 1.2. go into the menu. Setup, System Searching, Positioner Setup, and try using the options to increase your signal quality.
Please post back, after nudging the dish, with any increases, in your signal quality readings, on 19.2E.
Either your dish isn't hitting the correct points, for maximum signal quality, your dish has slipped, so the elevation is slightly off, you have a problem with your LNB/cable, or your dish needs re-aligning, starting with ensuring that your pole is plumb.

Thanks Mick12334
I've used an dreambox "satelites.xml" list and i can see that i can open the channels but they freezes all the time , that means that my dish isn't hitting the correct points, but i don't understand why the dreabox still haven't any problem with the same transponders. Or maybe the tuner is not as sensitive as the DM800.

All satellite receivers have different tuners, as soon as you posted the SD readings, on 11686:
With frequency 11686 / 22000 i get SNR 8,50 dB 53% BER: 0 and i don't have a long cable run thats arround 5 meter.

There is very little chance of getting the HD channels, with those figures for SD.

I do have a different opinion.
I had both boxes as well as many others boxes .
The difference between them all is visible only to the limit values
say below 50% or rainy weather.

There are minor differences between them in the reception.
Now, whether cosmetic or practical irrelevant.

It can not be a signal on DM800 and that you do not receive on VU + receiver nothing.
also most of HD channels on satellites have significantly stronger signal than SD channels.

So if you compare the signal strength of the both, and it is less than say 5% max 7 % on the channel receiving both
then it can not be the reason for your problem.

I can receive on all VU + receivers HD channels with less than 50% signal.

to add

I've read on some forums time ago
that defective electrolytic capacitors can cause tuner problems and a red light on the VU + Duo.

I Bought a new LNB 0.1 and got following signal on Astra 19,2 E:

S-2 10729 V 22000 8PSK S-2 10729 V 22000 8PSK
Before with LNB 0,2 = SNR 72% Before with LNB 0,2 = SNR 90%
Now with LNB 0,1 = SNR 74% Now with LNB 0,1 = SNR 94%

This is a huge difference and I believe the old LNB was broken or the specifications are not good
But you did not write whether they were DUO or DM800 signals

I Bought a new LNB 0.1 and got following signal on Astra 19,2 E:​

VU+ Duo
11156 V 22000 5/6
Before with LNB 0,2 = SNR 60%
Now with LNB 0,1 = SNR 73%



S-2 10729 V 22000 8PSK
Before with LNB 0,2 = SNR 72%
Now with LNB 0,1 = SNR 74%



S-2 10818 V 22000 8PSK
Before with LNB 0,2 = SNR 70%
Now with LNB 0,1 = SNR 73%


S-2 10906 V 22000 8PSK
Before with LNB 0,2 = SNR 68%
Now with LNB 0,1 = SNR 70%

Then following frequancies still have no signal on VU+ Duo

S-2 11127 V
S-2 11229 V
S-2 11259 V
S-2 11436 V

So i guess that this tuner haven't enough capacity to catch S-2 frequencies.
Is there anyone who has changed to any new tuner?

How did you install your new LNB?
On a motorized system you should send the dish to 0, or your True South satellite, to keep the skew. LNB rotation, correct, as a motorized dish automatically selects the correct skew, as it moves on the polar mount.
Given that you are using a 1.2M dish you should have no problems, with those signals, as they are all on the Europe beam:
Code:
http://www.lyngsat-maps.com/footprints/Astra-1KR-Europe.html

Can you post any pictures, of your dish/motor, and as it's a 1.2M dish are you using a V-Box II, and diseqc 1.2, to drive your dish?
