DF2ET hi sri in TA no Permit 2.4 GHz Transmit yet, we wait permition window only for QO-100 sat uplink QRG. Need some more time. Hope in rest of my life Ican see. hi hi
It was horrable what I heard today on the transponder. What is happened in the last twenty years. I never heard like this on old AO10, AO13 - So sad.
Hm, i don't think he is calling 'on 40m', because he doesn't use any callsign. It looks like he is doing this on purpose. Just ignore it, people who do this crap probably like the attention. Too bad it happens.
And, on HF, the pile-up stations usually can not hear each other, this relieves the called station heavily because the pile-up is distributed accordingly. On the satellite transponder you can see and hear immediately where the called station is listening.
This also reduces the advantage of split mode enormously ...
Remember, one of the reasons for duplex mode on satellite transponders is the need to constantly monitor your own emissions and signal quality. In split mode this is no longer possible for all participating stations!
So from my point of view split mode can not be preferred.

Thank you for the reply Mike. I've just done a fresh installation with the newest Nvidia Jetson Nano Image, then followed the package installation instructions you've provided. After that (and a reboot), I've went and got the DVBSDR from Github and started install.sh. This runs for a while, but then drops out with a error message "ffmpeg.c:39:10: fatal error: libavcodec/avcodec.h: No such file or directory". This can be resolved by installing "libavcodec-dev", but then you get another missing package and another.
Here's the complete list of all packages missing and error messages, as well as the messages I get when trying to receive the UDP stream with jetson_nano.sh
picam still works fine, the stream however does not. You can see the stream getting received fine with tcpdump.
That's why we are here.
Correct ....
Your hint was useful. Made Lime FW update, now the Lime is running again ...
tnx.
Robert
After several tryes no success on Nano
Yes, the same here. I give up. To make matters worse, the Lime Mini died yesterday while testing with various Jetson Nano Images. No more power, no clean DVBS-2 signals ...
I do not know what happened.
Robert
Hello everybody,
Creating a boot SD for the Nano seems to have current content with the latest images from Nvidia as it did in April of this year.
With a current Jetson Nano Boot SD and the installation routine for DVB-SDR from https://wiki.batc.org.uk/Jetson_Nano there is no FFMPEG program at the end of all installations!
The compilation process is aborted:
Makefile: 32: receipe before target 'ffmpeg.o' failed.
make: *** [ffmpeg.o] Error 1
The subsequent installation of a standard ffmpeg package is probably not right, because it does not work.
Now the question arises for me with which SD image of Nvidia at that time Evariste or G8GKQ created his boot SD?

Hello Alessio,
still no success..
What version of Ubuntu on Jetson you are using?
Here Ubuntu 18.04.3 LTS \n \l

Still no success...
I cannot see the Ethernet signals from the LVK373A with wireshark on the Jetson Nano!
Any hint how to connect the Ethernet between LVK373A and the Jetson Nano?
Maybe direct line with crossover cable or anything else?
Robert
yes, with the pi camara it works fine with best quality.
So I thohgt it´s only a small step to get signals from the LKV373A by only change the video input source....
Robert
Yes, same files from Github.
But, I installed the older Firmware 3.2.1 ---- image here - https://developer.nvidia.com/embedded/d ... -l4t-3_2_1 ------ on the Jetson
with this installation instructions before:
sudo apt-get update
sudo apt-get -y dist-upgrade
sudo apt-get -y install git htop nano vlc v4l-utils
Robert
yes, IP is correct, checked before with VLC on another PC. There the stream is working...
Script is from Github, yes.
Are there Video parameteres in the IPTV Server to change?
The video settings are still the same since firmeware update and reboot.
I thin here is shown that there must be a contact to the LVK373A

and so on
GM all,
had first success with the Jetson Nano, Lime SDR mini and the PI Version 2 cam. DVB-S2 transmit ok.
Yesterday the LKV373A arrived, and I did all the steps from https://wiki.batc.org.uk/Jetson_Nano with success.
Can watch the output from the LKV373A on VLC with the stream adress udp://@239.255.42.42:5004.
So far so good.
Now I tried to connect the LVK373A to the Jetson Nano via ethernet, and start the software from Evariste with script modified for IP input.
Transmit of DVBS-2 carrier ok, no error message from the running script, but no video transmitted.
What can I try? Maybe wrong ethernet connection between Jetson Nano and the LKV373A?
I´ve no Portsdown between.
If I change the script, the PI cam still working. Do I have to remove the PI cam hardware?
I´ve no idea what I can try as next step...
Any hints?

Hi Uli,
can you measure the return loss? Would be interesting.
73s
Robert
Mike,
that's a good hint. I will browse the forum for this solution ....
Robert
Mike, sure, I read the documentation and had the described problem with Lime and Pluto.
I'm not a fan of VOX circuits, especially as the Lime's and Plutos send a lot more uncontrolled when switching modes.
For me, a clean solution would be a software link with the PTT button, which could trigger adjustable time delay to a COM port .... Unfortunately, it does not exist yet ...
It remains only the solution proposed by you until someone adds the program code ...
Robert
