valid background for MSG Fire Tracker

Roland Fechter
 

Hello,
just a short question:
where can I get a "valid Background" for my Fire Tracker ?
Thanks in advance,
Regards
Roland

Hi John,

I have changed the position of my indoor antenna. The window is not an obstacle now.
SNR has increased from 4.5 db to 7.0 dB. The reception of EUMETCast files is back!


Thank you very much for your help.

MED fires

Roland Fechter
 

Hallo,
Unfortunately the areas bordering the MED are again plagued by fires.
Which is the best programme for seeing these ? At which UTC hours ?
Do YOU use still the msg fire tracker - if so which version please ?
Thanks in advance,
Regards,
Roland

Hello Arne,

Yes, that's correct.
My dish is now up against my kitchen window owing to the expanding fir
tree.
Time to get back inside it with some rope!

Could your momentary SNR peak be caused by someone standing next to the
dish, actively blocking >another interfering source ?

No, I was the only one at home and just happened to be writing email's on
my other computer and noticed the SR1's readout dial jumping around - well
upwards.
It was just brief increases lasting only a few seconds each time.

Yes, it was far too hot - well, humid, here yesterday to sit in the sun,
even with a cold lager.

Just watching the thunder storms building over Brest and the western
English Channel heading our way.
Better get my plastic lemonade bottle rain shield back on the LNB - very
gently as I'm getting a good signal at the moment.

Just a thought, do you think the unusual design of your dish increases its
beamwidth?

Best wishes,
John.

Hello John,

Those CDROMs are only for a couple of days. Don't have many neighbours in that direction. I choose not to put the silver side into the sun to prevent blinding reflections.

About your dish, so the tree is blocking interference from 13E and 16E probably. That is good !

On http://www.satsignal.eu/mrtg/performance_eumetcast-europe_snr.php http://www.satsignal.eu/mrtg/performance_eumetcast-europe_snr.php you will see that others did not record this peak.

Yes these chairs are nice but currently it is too hot over here to really enjoy the sun !

Hello Arne,

Well, it certainly was 'something.'
I guess I should pass the timings on to EUMETSAT to see if they tally with
anything they were doing.

Regarding your new dish:

http://home.hccnet.nl/a.van.belle/GEO/ExtendedT90.jpg

Mmmm, interesting, and colourfull
I wonder what the neighbours thought.

Perhaps you should have just taken it easy in one of those nice comfortable
chairs in the sun with an ice cold lager?

Best wishes,
John.


Re: Signal

geojohnt@...
 

Ian, James and All,

This really is curious?
My SNR is (now) about the same as it was ages ago.
That is apart from lunchtime's brief sizzling SNR.

Arne is suggesting possible 'interference' from an adjacent channel on
EUTELSAT 10A or from an adjacent satellite.
My dish can 'see' round to 10 + degrees west but with 10 E receivable just
west of a large bulky fir tree, it cannot 'see' any satellite to the east
till past Astra 19 E.
So if an interfering signal was coming from an adjacent satellite to the
east it is currently blocked by the fir tree.

Regards,
John.

Re: Variations in the Eumetcast signal

LaurentD
 

Thank you Arne and John for your help to understand what happen with my settings. For the moment I have no choice: I must use an indoor antenna looking out of a window.
I'm waiting the "green light" from my owner + several administrations to install a dish on the roof of my buiding.


I ignore why since 10 days my signal dropped below 6 dB (SNR) even during night period. You confirmed that nothing has changed in Europe (Ku band), so I need to change very carefully the position of the antenna.
Most of the time, the reception is affected by the position of the sun during the day and especially in summer but it's the first time that the signal is below 6dB so no reception is possible.


Many thanks to the group.


Laurent

John, you must have had a clear sky moment because over here not much changed until I temporarily "extended" my dish !

Using old driver CDROMs and neodymium magnets solved from crashed HDDs I just extended my dish a bit.

T1 went up from 11.6 to 12.2 dB SNR, even better than the values I had a month ago !
T2 went up from 11.4 to 12.0 dB SNR
All measured at clear blue sky and 27 degrees in the shade !

I started adding the CDROMs on the eastern edge but this did not give a noticeable improvement.
Only after I added them on the western edge too my SNR improved.
See http://home.hccnet.nl/a.van.belle/MRTG/dvbdataex-snr-p1-tbs6983-tunera.html http://home.hccnet.nl/a.van.belle/MRTG/dvbdataex-snr-p1-tbs6983-tunera.html July 17th after 14:20

This is only a temporarily measure, these CDROMs don't follow the parabolic shape very well and won't stand the baking sun for long.
But even if I added a section with the correct parabolic shape on both sides, it wouldn't be as effective as new larger dish. Much of the signal reflected by the CDROMs "spills over" the sub-reflector.
On a conventional Offset dish you may get more SNR gain.

Try before you buy ! (a larger dish) :-)

Hi

Is it just me or does there seem to be a lot of data missing today. I have missing segment on MSG and Metop A/B. My signal level is just the same so not sure whats going on

===========================================================================

Graham there has been packet losses this morning, I think on 3
occasions.
Work going on at Eumetsat's end.
I did notice this morning a substantial rise in the T2 SNR and indeed
for the first time I had parity with T1.
However it now seems to have fallen back to its original 0.7 - 0.8 db
SNR below Transponder 1.

Regards,
Douglas.

Re: Variations in the Eumetcast signal

geojohnt@...
 

All,

Just to throw a spanner in the works, my TP 1 BS SNR has 'just' increased
considerably.
It had been this morning around 13.1/2 - now UTC:

12:19 - 13.4 dB
12:22:30 13.6 dB
12:22:55 13.8dB!

During this time stepping between the 'highs' and down to a low of 13.1 dB.

Now, 12:30 back to 13.0 - 13.2 dB.

My highest ever SNR in the past was 13.4 dB.

Regards,
John.

That's what I find on CelesTrack. Eutelsat 10A has NORAD number 34710


EUTELSAT 10A

I have not done tracking for years. I cannot say at the first glance whether these
TLE are outdated. The figure 8 shape will probably also depend on eccentricity.

Hello Ernst,

Genau - aber .......

I have tried two official agencies to obtain the inclination data for
EUTELSAT-10A to find out the equator crossing point, but failed.

I have checked, with updated keps on WXtrack EUTELSAT-10A's movements.
The satellite is over the equator between 04:29 to 04:57 UTC.
And between 16:30 to 16:58.

Now, I cannot guarantee those times are correct, they are purely from
'watching the inclination on WXtrack.
