Re: Gibertini OP 125L

Ernst Lobsiger
 

John,

The photo is attached to my first post of this topic :-). Bear in mind that the pole must be 55mm in diameter (minimum) but should rather be 75mm (optimum for the clamp and high wind loads). The antenna must be attached on top of the pole. If you mount it in front of a longer pole you will be very limited in elevation.

I have not yet fine tuned my OP 125L antenna. Far too hot for antenna pointing experiments these days ...

Regards,
Ernst

Hello Ernst,

Sorry to hear about your problems - and more so that you are having them with a Gibertini dish.

I am hoping to upgrade my system this autumn and would have gone for a 1.25 m Gibertini dish instead of my 1 m dish 'standard dish.'

Somehow, Gibertinin dishes have the reputation of having the highest gain of 'same size dishes.'

I wonder if you could please send a photo of the dish/az/el pole fixing arrangement to my personal email address?

The 1 m (I think) Gibertini dish that EUMETSAT used for their EUMETCast Conference some years ago had a simple but robust looking mounting arrangement.

Best wishes,
John.

I drove another 300km to get a second antenna mount for my Gibertini OP 125L.
And guess what: I have exactly the same mechanical problem with the elevation

OP 125L via Germany (!). Today I mounted the dish on my modified tripod. I Q&D
pointed the antenna via landmarks and elevation indication only. I started with
EsNo = 14.2dB on T1 which is +2dB from my best results with the old TRIAX TD88.

During the next days I'll try to fine tune my dish. If the elevation adjustment
problem I expect from my experiments with the bare mount on a working table
persists I'll eventually contact Gibertini in Italy directly. Stay tuned.


Re: Tellicast client version 2.14.4 for Linux

David and Hugo

I'am just back up and running with my new antenna. There seems quite some change
under GNU/Linux if you are receiving with dvb-s2 PCIe cards. K.-P. issued a completely
revised dvb-eumetcast script to setup smcroute. I have run my own adapted version
of dvb-eumetcast for multi transponder and per client multicast interfaces dummyN
since fall 2017. Now I have to decide how to go on. K.-P.s May 2018 version of
eumetcast-channels.cfg also lacks the channel names which is kind of a problem.

The channel configuration file is sorted by IP and does not correspond to
the sort order of the PID and channel pages on www.eumetsat.int. There are
multicast routes setup that cannot be matched to known channels. Furthermore
the link for upcomming changes HVS-1 --> HVS-2 does not work anymore (??) !

https://www.eumetsat.int/website/home/News/DAT_3942692.html

I noticed PID 511 is gone on BAS T1 (probably long ago) but on the other hand
EUMETSAT says that there is no PID 611 on HVS-2 T2 anymore. But I still see mean
53.7 KBytes/s traffic on PID 611 that is heading for 224.223.224.1:6099 (??) !

There is a new EUMETCast CD image from today August 2nd 2018 on ftp.eumetsat.int.
The new Linux client includes the new per channel parameters. receive_buffer_size
is "(in MB)" which probably means MegaByte but 8000000 does not make sense to me.

I'll install the new 2.14.4 client and see what I find out ...

Cheers,
Ernst

I've tried the 2.14.4 Windows client simply by replacing the .exe and .lic files, and seen no difference.

There are two new parameters:

delay_channel_leave_time= will keep the multicast channel joined, needed only for multicast on WAN network, i.e. EUMETCast Terrestrial

receive_buffer_size= sets the kernel receive buffer (in MB) for the specified channel, helps mitigate slow IO performance of the computer or high load conditions

but they aren't documented in the program's Web Help, and the buffer had been set to 8000000 for all EUMETSAT channels. This leaves open the questions (a) is it bytes or megabytes (!), and (b) what is a reasonable value to use. I'd like to use 600+ MB for the HVS data but, as you hint, in a 32-bit system that might be a little limiting (if three Sentinel full-resolution files are sent at once). I have an outstanding query with EUMETSAT about this.

Do you have these new per-channel parameters in Linux? In the Web help?

Cheers,
David

Re: Tellicast client version 2.14.4 for Linux

Ernst Lobsiger
 

Hugo,

If you just receive TC there is *NO* reason to use amd64Bit. Until one year back I only used 32Bit Linux (kernel 4.9.0-3-i686-pae to use my 8GB of memory) on TC receivers. Some distros begin to slowly turn down the 32Bit support but Debian testing "buster" appearently is and will still be available as 32Bit software. I use amd64Bit because my receivers also run SNAP 4.0 to process Sentinel OLCI EFR images on the fly. So it was mostly curiosity on my side and I wanted to test the TBS-drivers under amd64Bit too. My multiarch receivers prooved surprisingly stable. Of course EUMETSAT should provide a full amd64Bit suite for TelliCast. The TC client could certainly benefit from the much better memory handling. But that's something EUMETSAT promised when they prepared to change to DVB-S2 years ago. So I do not expect that we get rid of the stone aged pcscd and etokend stuff anytime soon ..

Cheers,
Ernst


Re: Tellicast client version 2.14.4 for Linux

Hugo
 

Ernst,

Because all the Tellicast software is 32bit , is there any reason why I should use a 64bit OS ? My receiving PC is only for receiving Eumetcast.

grts,
Hugo


Re: Tellicast client version 2.14.4 for Linux

Hugo
 

Hello Ernst and Christian,

Thanks for the quick reply ...
Yes it must be something with the 32bit USB subsystem. My OS before the crash was Debian 8 and I I didn't have any problems installing Tellicast. This time I choose Ubuntu 18.04.
I'am going to read your 'how to' and will report back if I'am able to get it to work. I can always reinstall Debian on my system.
I always wondered why Eumetcast must be encrypted. Every member of Europe is paying for it via taxes, and the 60 euro is only the cost of the dongle....Probably because it's Europe...
And another thing, the Tellicast software should be open source ! :)

Kind regards,

Hugo


Re: Tellicast client version 2.14.4 for Linux

Ernst Lobsiger
 

Hugo

The 32-Bit USB subsystem might be the problem:
Have you resolved all the missing dependencies?

Is pcscd and etokend running?
Have you edited the etoken rules?

I have not yet installed the latest TC client. Here is what I use for Debian and Devuan ...

Cheers
Ernst


Re: Tellicast client version 2.14.4 for Linux

Christian Peters
 

Hugo,

I changed to 2.14.4-2 without any problems on Debian 9 stretch.
You should ask Ernst for his installation documentation on 64 bit systems, maybe there are some useful hints what goes wrong. I think the EKU software/libs which seems to be still 32 bit code could make the trouble.

Regards,

Christian

A few days ago I had a hard drive crash on my tellicast receiving station. So I had to install a new OS ( Ubuntu 18.04.1 LTS) and the Tellicast software.
I decided to use the latest version from the Eumetsat ftp site : version 2.14.4.
However, I have problems with this version.
I don't have anything in host_key_4. It should be something like host_key_4 = ****-****-****-**** (Aladdin EToken PRO) This means that I get a lot of 'missing key' in the log file. I do receive the channels SAF-Europe, SAF-Global, SAF-Africa and SAF-Americas. These channels are probably not encrypted and so I can receive them.
Does anyone have any ideas ?

Re: Gibertini OP 125L

Thorsten Miglus
 

Ernst,

I feel sorry that you have so much trouble with the dish.
But I am happy that you are up and running now.
Actually my TP1 SNR is up to 15.4 dB during chilly night hours.
Fine tuning is a challenge. I was sure to have the optimum.
But sun - sat - collinearty told me that I was 0.4 degrees west.
Tightening the eastwards screws of the pole mount a little to turn the dish a tininess east gave me +0.3 dB SNR.

GOES 17 ABI Problem.

Douglas Deans
 

NOAA have published an update on efforts to resolve the cooling issue with GOES 17 ABI instrument.
Please see :-

https://www.nesdis.noaa.gov/content/experts-moving-closer-resolving-troubles-noaas-goes-17-abi

My interpretation is that it is not fixable but that a number of clever workarounds will limit the losses. VIS channels are of course unaffected.

I've not detected any heat problems - here it /only/ got up to ~25C. Now the issues are thick cloud, rain and wind causing low and variable signal. A couple of days back even the BS (and Sky TV) dropped out!
