Hi all!

Signal drop is caused due to excessive snow fall in Aflenz Austria (Satellite Uplink): 800mm in 24h!

Betreff: [MSG-1] TP 1.

 

All,


Ah good.

Well, not, really.

 

I've just accessed David's EUMETCast Europe reporting page and found that everyone is experiencing 'dropped' SNR.

Mine was down to 9.7 dB earlier which caused HVS-1 to lose lock.

 

I'm back up to 11.3/4 at 12:30 UTC - where it should be 13.0 dB.

 

Regards,

John T.

Thomas,

We have a saying in English:

if it ain’t brokedon’t fix it

    1. Leave something alone; avoid attempting to correctfix, or improve what is already sufficient (often with an implication that the attempted improvement is risky and might backfire).
      I know it’s an ugly-looking antenna, but you know what they say: If it ain’t broke, don’t fix it.

I quite often find when suffering, what I think is, slightly reduced signal levels that 'giving the dish a bit of a tweak,' makes things worse.

Best wishes,
John.

Hello Thomas,

Sorry for the delay in responding.
I've been visiting my Belgian relations attending the WW1 Armistice ceremonies in Ypres.

You are right.
The accuracy of motor driven dishes is good enough for EUMETCast use.
OK for satellite TV where signals are mostly stronger and where accurate dish alignment is not so critical.

Best wishes,
John.

Thomas,

I'd guess a diseq motor  mount is not for EUMETCast with a 1.2m dish.
I'm quite sure you will run into mechanical precision problems and
also problems to feed the motor with current via your TBS-5927.

I am using a Stab HH120 with my 110cm dish, It's rated for  120cm through

But i was thinking to just go with the dish setup alone as I don't move the dish anyway

Got a TBS 6903 card which I can move the dish with if I want

Cheers

Re: Hvs

Hi Thomas,

 

The Sentinel data on HVS-2 is indeed used for more specialized applications. Much of the data can also be had via the Internet and thus the effort and expense the required to receive and decode is most likely not in proportion to its use for many of the amateur users.

 

Modis data comes from the Aqua and Terra satellites. If you are interested in these, you should also have a look at the VIIRS data from Suomi NPP and NOAA20, which is the follow-up of Modis.

Hi Ferdinand, 

 

Thx for the explanation. 

 

I already filled the form, but i was pretty flashed about all the new stuff in there. 

 

The HVS on transpoder2 is still a little mystery, because does anybody of the enthusiastic users working with those data? 

 

First i thought sentinel data offers a eay for much higher resolution and better quality, but i guess those data are only usable for analyzes. I am happy if iam wrong... 😄 

 

Another new (old) thing i discovered is modis-l1 data. No idea why i never looked deeper into this. The images are quite impressive. 

 

But which satellite does transmit modis-l1 data? Hopefully it is not an obsolete feature... 

 

Many questions.... 😄 

 

@David 

 

I thank you for the information about the upgrades. How about the other tools which not in the tool packages? 

 

Kind Regards 

Thomas

Hi Thomas,

 

You do not need to request HVS as such but you must make sure you have requested/selected the items in the EO portal such as Third Party Data Services for Goes East and West, Himawari etc. which are delivered via HVS-1 and the Copernicus entries if you are looking for HVS-2.

John, 

unfortunately i had no time yet to install the new dish. The basic service is very stable indeed.Even in heavy cloud conditions with rain the s/n dropped just 0,5 db. 

By the way... is it a good idea to mount the new dish on a diseqc motor? Could imagine that the repeat accuracy is not precise enough.

Hello Thomas,

With a 120 cm dish you 'should' get around 2 dB better SNR with a correctly aligned dish.
Very important for HVS-1 services which have a much lower link margin level than BS.
Rain/snow signal attenuation reduces SNR but BS with its higher link margin level is not as badly effected as HVS-1 if the signal attenuation is high.

Best wishes,
John.

As iam still confused about the modcodes and hvs service, i use transponder 1 with all codes enabled

I had almost almost all eumetcast related tools registered some time ago.

Do i need some upgrades and how much will those upgrades cost?

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

Thomas,

That's excellent news about the receiver.

Yes, your software is over 6 years old, and there have been updates - quite a few of them - to cover many of the new services from EUMETSAT. There are upgrades available:

MSG Toolset Plus upgrade:
https://order.shareit.com/product?vendorid=200278389&productid=300877399

HRPT Toolset Plus upgrade:
https://order.shareit.com/product?vendorid=200278389&productid=300878427

Good morning, 

first off all i wanna thank you for all the great informations and assistance. You brought me a lot further. 

As recommended by David I ordered an used 5927 which i found for a reasonable price. 
Additional i purchased a new dish with a diameter of 125cm. Hope my Neighbor does not think E.T. has landed.. :-) 

I expect a lot better performance in reception, but also new challenges. 

With the present equipment no improvements seems achievable.

David and Thomas,

The EUMETSAT Setup Guide is for Windows 7 (not XP)

<Cite>
3.6 Running SS2XPFIX
SS2XPFIX is a small console utility created by CrazyCat which is setting one bit in BDA demodulator register.
</Cite>

IIRC this did the trick to enable the use of the STV0903BAC demodulator to receive at least
the BASIC MODCOD of the Transport Stream (TS) without really being fully VCM capable.
Not sure something like that was integrated in later BDADataEx versions (I doubt it).

Ernst

Will be interesting to see how they can blame Eutelsat for this.
I know 0.5 dB (I am nearer 0.8dB up here) is small but when you are on
the periphery of the signal it makes a huge difference.

You have a real problem with your system.

With a 110 cm dish in your location you should be seeing an SNR of at least 13 + dB.
