Véi, só vc tá preocupado com esse tal de carrier lock... relaxa....

What can cause the carrier lock level to not be as high as expected?

I noticed that my carrier lock level is sometimes lower than expected for the signal level we see on the spectrum. Sometimes 40-50 even 30-40 other times 70-80 (mostly at nights).

Comparing with signals of equal level, my D value is lower in relation to another signal of the same level and FEC, the difference can be even 1 unit of D.

At images below you can see my signal at different times has very different values considering the same configuration.

I've already checked the connection cables and everything is well connected and of good quality.

I have been discussing this effect with friends but we have not yet been able to identify the reason for this variation in the level of my Carrier Lock, which means that my D is not even the most suitable for the signal level I get on the satellite.

My setup is 2m dish prime focus, DATV easy 3.05 poty.

All comments are valid and welcome, this is not a big issue, just trying to understand what this happens and what make your Carrier higher at satellite.

Nowadays i use only the F1EJP windows application ( for 333kc it works fine ).

Thank you

Hi all.

It looks my H265 hard or/and software problem is solved.

Now the base situation is correct i can play with other settings.

Thanks to all for helping me.

Thanks and 73,

Hello Bert,

Should I "revive" this thread a bit pse...

I finished my setup for DATV with Pluto and OBS, etc. Streaming ans work in local test at the desk, need some ajustments but that will be done.

Read tons of post on the internet about H.265 record in OBS to send to Pluto, but I´m a bit confused and lost and need some guidance.

Can you or other friend help me a bit to guide me to how set my OBS for H.265 video to send to pluto?
I have a powerful computer with RTX 2080 Super Ghraphic Card that suport H.265 codec, and I want to use it instead to spend more 95€ in a box encoder if I can use my computer.

Can someone share their settings that are working today?

Appreciate.

73 and good 2023 for all.

Fabiano, could you share here what you had to do to make it work with the external 50 MHZ reference?

I'm sure others would benefit from the information.

Initially you added these two settings, but it didn't work.

fw_setenv refclk_source external

fw_setenv ad936x_ext_refclk ‘<50000000>’

What was done to make it work?

Thanks!

HI,

It was a nightmare, but I have notepad after get sucess, this is my notes:

fw_setenv refclk_source external

fw_setenv ad936x_ext_refclk "<50000000>"

pluto_reboot reset

Hi,

Everything is okay now.

Pluto is sync with 50Mhz and LNB with 25MHz.

Thanks all for help, Matthias

Seems something did not works...

I have no reception after perform the commands

Follow this guide

Worked like a charm !

Now let come back and try againd to set it to External Ref. and clock of 50MHz

I see manny diferent commands to achieve that, can please confirm that I can use this:

a) Set to External clock:
fw_setenv refclk_source external

b) Define the frequency:
fw_setenv ad936x_ext_refclk ‘<50000000>’

Should change config.txt file also or not?

Tnx de CT7ABD

Quote from iu4gav

have you tried with the recovery?

Let me know them the right way to perform Factory Reset, I want to clear everything and start from point 0.

Quote from DC7KG

Hi,

the Pluto uses 40 MHz x 2 = 80 MHz, you have to change the factor from 2 to 1, when you use 50 MHz.

Detlev

Sorry but I´m not sure if I understand you answer.
Is pluto able to be set to 50MHz instead 40MHz or not?

This is the circuit im using.

Anyway I´m not able anymore to roll back settings and now i can´t access my pluto anymore.

Quote from iu4gav

Ok, so if I understand correctly, give 50mhz to the bar, then divide it by 2 and 25 to lnb.

Yes, here is my diagram, maybe better to understand.
I can´t understand what happens, hope someone give me a light...

Quote from iu4gav

"correzione_xo = 50000000"

Why 50mhz correction?

Because I need 25MHz also for LNB after divisor.

Hello,

I'm setting up my QO-100 station and everything was working perfectly for reception for few weeks only since the SG Labs preamp and amplifier still haven't arrived.

After connecting and installing the U.FL-SMA plug and inserting the commands to change the reference signal to "external" from the LeoBodnar GPS, my adalm-pluto no longer accepts connections over the network with the SDR-Console. I also unable to connect via direct USB to PC although I have access via ssh with putty to the IP.

I use LeoBodnar GPS with lowest output power and 50MHz clock that go to Frequency Divider board that I build to get 25MHz for LNB as well.

I've been trying to find help on the internet for 1 day, but nothing seems to work, and I need help if any friends here can help.

I collected the diagnostic log and the result of some commands, which I leave below:

Any way to roll back the Pluto for Factory defauls settings or RESET everything to default and start again from scratch?

Appologize for long post, I understand is quite boring to read this kinds of posts, I learned a lot here before decided to build my own QO-100 Station, and I have help from some of you too.

Appreciate your time if you read until here. Hope to have my Pluto back.
