Hello, I'm using a Dreambox DM920 UHD 4K DVB-S2X twin tuner and I can not pick up any channel or signal at 3 frequencies in the 5W.
The frequencies are:

11054 V DVB-S2 / 8PSK 29950 3/4
11509 H DVB-S2 / 8PSK 29500 8/9
12648 V DVB-S2 / 8PSK 29500 8/9

I've tried another DM920 UHD 4K receiver just like mine but with the tuner with FBC and it works on those frequencies.
Has anyone verified this?:(:confused:

11054 V DVB-S2 / 8PSK 29950 3/4 it is not multistream, here you can find latest satellites.xml including good 11509 and 12648 multistream at 5W.

Thanks for your help but the problem persists even with the "satellites.xml" file left by Maumixio.
From what I see the problem is not caused by the file "satellites.xml".
As I said, using another DM920 but with DM920 UHD 4K DVB-S2X twin tuner FBC, I can already have signal and see the channels of these frequencies.
I think it's any bug with the drivers and DVB-S2X twin tuner.

My two single tuners are both Sì2166D (not twin) and I can get good image from Eutelsat 9°

I've done more testing and it seems to me it's a matter of sensitivity of tuners.

The BCM 45308 tuner is (better) more sensitive than the Si2166D tuner.

These factors allied to the small size of my satellite dish, give this negative result.

Thank you all for your help. Best regards.

I have the same tuner and box and all three frequencies are fine.

I wanna ask a kind of silly question, on screenshots from 11509H I see "dreamOS".. is openatv also working with multistream if using MultiStream FBC Tuner??

I do not have a MultiStream FBC Tuner but a twin Si2166d in ATV should not be a problem.
