Re: Eumetcast update - you may want to restart your Tellique client software

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

Thanks for a very informative update and well spotted on the
channel 3 bandwidth. Perhaps that is the most important upgrade of
all.

I didn't spot it, to be honest, I was told....

I am noticing already with the new Tellique that the .fsy seems to
be staying much smaller. With the older software I regularly had 2
large files despite never having a problem with segment loss...still
that's history now!

Due to the Eumetsat changes, rather than the upgrade of the Tellique
client.

I have just received your original advice direct from Eumetsat
OPS. in a mail. I really must repeat that the service from Eumetsat
OPS is superb.

It was the result of some discussions I had with Eumetsat about a
specific missing segment - just occasionally I dig into the log
files and if one PC gets the segment OK, and the other failed, I try
to understand why. Eumetsat have a very detailed understanding of
the operation of the Tellique system resulting in the tip which I
suggested passing on to this list.

Superb service from Eumetsat, as you say.

Cheers,
David

Douglas,

The bandwidth on Data Channel 3 was increased as well, so there may
be a greater net flow of data into your PC for the Tellique client
to sort out. Unfortunately my own graphs only show net traffic, and
not per channel.

Yes I realised after I wrote the advice that there was perhaps
a "delete regularly" implication, which wasn't really intended.

It seems that: if you don't have a high error rate, the .FSY will
stay as a single file, and something round up to 50MB is OK. If
lots of fragments start to get cached (and the expiration time
before was 7 days), and the FYS files approach 100 + 100 + 50MB
(i.e. three files), then there is a chance that accessing these
files may cause a timeout in the Tellique software perhaps resulting
in missing segments. Reducing the expiration time should reduce the
amount of caching.

I back Arne van Belle's recommendation to delete any .FSY files
prior to starting the Tellique client. Doing this as part of the
shutdown process would be ideal!

In addition, if you get a bad segment spell, due to high wind or
whatever, and the .FSY file is more than 50MB or there is more than
one file, restart the Tellique client as described.

Cheers,
David

the real benefit of that won't be fully appreciated until all SEVIRI
products are back....but excellent news. With all my troubles yesterday I
did not notice this.
I am almost certain that is what brought about the chaotic computer
behaviour, but why this time, when such operations have been carried out
many times before without incident to me. Still it was a good excuse to
update the very old software.

Just restarted my system, has been switched off for a couple of
weeks. So far no missing segments!! Perhaps it is because there is
less data but I would like to think that the changes have reduced my
missing segment problem. Let you know next Tuesday if the improvement
is permanent. (No other changes to system, did delete 0.fsy file as
recommended.)

seem an awful coincidence that the 6th was the day that my disasters
struck.
All continues to go well so far with the new software.
The above advice is not implying that there is benefit in deleting

Lawrence, that is coming later this year to cover another MSG-1

digital Met-6 (Rapid Scanning Service) and Met-7 (Archive Direct)
off the Internet if you are registered. 24-hours delayed

Folks,

Following changes in the Eumetcast system tuning on January 6th to
optimise the file expiration time, you may find it beneficial to
restart your Tellique client if it normally runs continuously and
you have a good signal level, but still experience some missing
segments. This is what to do:

- in Explorer, locate the Tellique &#92;receiving&#92;tmp folder
- there should be one or more .FSY files
- if the files exceed 10MB in total
- stop the Tellique client
- delete the .FSY files in &#92;receiving&#92;tmp
- restart the Tellique client

If you restart your receiver system every day, then delete the .FSY
files prior to starting the Tellique client. There is no need to do
this immediately if you are not seeing problems, but when you do
need to next restart the Tellique software, remember to delete
the .FSY files as described above.

Cheers,
David

At least while it continues, I have not suffered a single missing

N.B. with the addition of more data to Eumetcast the expected cache

(Resposted - updated threshold from 10MB to 50MB).

Re: msg-1 reception with linux

Luca Bertagnolio <lucaberta@...>
 

Edward,

a few months ago I did successful tests under Linux, running Tellique
with a WinTV Nova DVB card, and the sharing the "received" directory
under Samba, so I could decode the files with David's software.

I sure can help you in your tests, but bear in mind that I am not
sure about how the Linux version of Tellique supports the eToken Pro
USB token. So this all might be a temporary solution, but it's
definitely worth trying.

In order to set up the DVB data reception, you have to follow the
instructions found on http://www.linuxtv.org/

The LinuxTV 1.0.1 driver supports the SkyStar2 PCI card, but not the
USB version. Please read all the docs included with the driver and
load the different modules in order to have Linux recognize the card.

You might not need to recompile the kernel, I didn't have to under
RedHat 8.2 at least. You will need a few modules for the LinuxTV
driver, all is well documented in the driver docs.

After that, I will share with you the tricks I had to do in order to
have Tellique work properly under Linux. But I will need to reboot
the PC to browse my config files, so I will do it another time.

Meanwhile, let me know when you'll be OK with the LinuxTV driver.

Best regards,

Luca Bertagnolio

Douglas,

I think that there may be problems resulting from trying to cram too
much down data channel 3, possibly the sequence errors we see on Met-
5 and some MPEF products.

What will happen on MSG-2 and MSG-3 where these bandwidths are fixed
and not adjustable? I guess that as dissemination will be via
Hotbird, the limited bandwidth won't matter. Just a thought, though.

Re: Sailing Channel gone?

Ian,

I did a rescan of the transponder, and infact it is gone. :-(

Kurdsat will then become by "beacon" channel, and hopefully "Breaking
the Ice" will stay on the transponder, as it is probably much nicer,
given the promos being broadcasted just now.

Sailing Channel is still available FTA on 11200V.

Looking at the static images I think aircraft trails, as you can see
the shadow of some of the trails on the lower clouds. The

Most interesting. I have been watching it all day. What really surprises
