Hi, people , just buy recently this tuner for my Vu receivers and must be drivers problem for this tuner on OPEN PLI , most of terestrial programs have max 52 % S/N or even 38 % at weak forecast and than even not receive at all. And i install VTI image 15 and this same tuner work there for 99 % or 80 min !!!!! No breaks in signal etc.So what happened in Open pli drivers that couse weak reception ?????????

I expect we have the same drivers in the Ultimo 4K image as other images have.
If not, then Vu+ ‘forgot’ to update our BSP with the latest drivers including this specific tuner. Can you compare the date of the drivers in VTI and OpenPLi?

Also on my new Duo 4K SE is the same , where exactly i can find dates of those drivers , is late and i want fast check this.

On VTI 15 i found only build date 2020-09-21 and version 2021-02-08 , there is no info like on open pli. In PLI i guess was latest DVB drivers 29 april 2019 ??? i don't remember , have to restore image.If those right dates so PLI needs new driver for this tuner which exist from september 2018 ?

I can’t imagine this tuner isn’t supported in our image. I’m afraid none of us owns this tuner so hard to improve the proper working of this tuner in OpenPLi. Do you also notice hickups in the picture. If not it might be that the way we show the signalvalue is different then in VTI. Perhaps that there are other members that own an Ultimo 4K + this specific tuner?
What is the setup of your tuner(s) in the Ultimo 4K? If you have three tuners installed what is the order of those tuners?

Like i said on Vu Duo 4K SE i have the same issue , but below 40 % on some programs often appears shredding , my Ultimo 4K config is Slot A : Dual DVB-S2X v2.0 tuner , slot B : This problematic DVB-T DUAL MTSIF Tuner and Slot C : Dual DVB-S2 old type tuner - using for blind scan on motorized antenna. You mean hickups , that is what exactly ? Maybe i have to switch for slot A and check how work there ?

It you are thinking about BCM3466, then under PLi it has SNR 51% (and value 15,1dB) on my DVB-T antenna and no any problems with signal.
I tried VTI and there is SNR as 99% permanently on my DVB-T antenna. AGC for both is 99%.
Posted 10 August 2021 - 08:37
I see 51% max on my Ultimo4K with the BCM3466 tuner, down to 47% on one poorer signal mux, and no picture problems.

Thanks you both for clearing this. Obviously the signalvalue of OpenPLi might be more realistic.
Posted 10 August 2021 - 09:41
.... I've also a dual TT3L10 T2 tuner in the Ultimo4K, it shows 100%, even on the poorer mux. (Maybe I should also have said I'm using OpenViX.)

On duo4k, on openpli develop (last release) 51 % SNR on DVB-T2 DUAL MTSIF.

And the picture is ok?

I have corrected the values for this tuner and they are correct.
About 50% are good values.
Less than 40% friezes of the picture.

@Dimitri; : Yes
Around 47% the last transponder (higher frequency) freezes a litle.
Posted 10 August 2021 - 15:42
Sorry not @Dimitri, @Frenske : Yes good picture at 51 %
Posted 10 August 2021 - 15:47
Hi again , great so many people show your results yes 50 % is enough to achieve very good PQ but below 40 % , especialy during bad weather signal freezes or disapear for long time.Here where i live , around Warsaw -Poland ,channel 51 , for example program '' Stopklatka '' is very weak and 38 % is lethal 
for him.I have good sat meter https://www.dmtrade....t2-c-combo.html which show on this 51 channel S/N 85 % so i believe in this measurement more than any VTI/ OPEN PLI etc, so one thing only left , must check signal during rain from this tuner on VTI 15 image.
