Date   
HVS-1.

Douglas Deans
 

Am I correct in saying it was the HVS-1 channel which Eumetsat added in-fill data to in order to resolve problems with the TBS hardware.
I have been quite busy at my computer recently which has drawn my attention to the BDADataEx icon on the Taskbar going green (instead of blue) quite frequently. On checking as expected the data rate is at 0 for short periods.
I cannot remember the full significance of the problem but I know it was detrimental to reception and may explain imperfections in my HVS-1 set-up.

Is anyone aware of what the current arrangement is and whether it has been changed.

I use the TBS 6903 for HVS-1 to separate it from the basic service on my SR1 for the occasional bad weather we get here in Scotland !

Regards,
Douglas.

Looks like GOES 17 image data has problems now as well.

No data since 18.00 UTC.

For what it's worth the latest image on the Dundee site is today at 05.00z for

Less data, fewer packets to lose!  But I see you've already made improvements.
I can't seem to find a notice about this from NOAA or EUMETSAT, which is a little unusual.  I don't see any files accumulating, though, which might happen if there were a format change.

Mario,

Well, here in the UK, summer has deserted us recently and for the second time in two weeks, I've put the central heating back on for a couple of hours in SW London - in August!

Global Warming?
My tomatoes in the garden are still green.

Best wishes,
John.

Mario Brustia
 

Ho John,
thank's for you report!
My descent cable is about 30 meters. An old LNB plus a very long descent are a very bad pairing.
I looked at the BLAK ULTRA 1 exit because they give it a suitable fit for long descents.

Seen then the cost very affordable, I think it is a test, which at this time I can do.

Of course ... then there is all the alignment ... but right now, with the temperatures I find on the roof ... I'm not on schedule! Maybe in September I'll make the passage to LNB

Thank's again to all!!

Mario,

>very hard to decode.

Just to say that I got out an old 85 cm dish and Inverto Black Ultra LNB that I used many years ago for EUMETCast  and found that my SR1 readings under clear sky conditions using this dish, which might not have been accurately aligned  were:

BS
SNR 10.9 - 11.00 dB
Link margin 5.0 - 5.1 dB

HVS-1
SNR 10.9 - 11.00
Link margin 1.6 - 1.7 dB.

That was using around an 8 m long cable run.

I agree with David to be cautious about some manufacturers LNB technical figures - especially noise.
However, Inverto publish very comprehensive figures for all technical aspects of their LNB's on their website.
And the Black Ultra range have increased gain compared to their other ranges.

Regards,
John.

Ferdinand ,David
I thank you for the exhaustive details.
The replacement of the LNB is due to the fact that it is very old (almost 15 years, bought to use on HB13) and the cost is quite affordable to try to gain a few dB.
Then in the future (at the end of housework ... David!) I decided to commit to receiving HVS from a receiver that would certainly perform better than the current one.
Have a nice day !!

Mario
===========================

Mario,

OK, and older LNB may well be worth replacing. I don't think Arne has carried out further tests than those where he recommended the Inverto Black Ultra. The Ultra has a higher output, so allows for more cable loss and splitters etc. I ended up with a different make, and four outputs rather than two, but I would recommend going for at least twin output.

Enjoy all the alignment!

Cheers,
David

Re: LNB to receive hvs1 and hvs2 simultaneously and SR1 enable 2nd RX input

Ferdinand Valk
 

Mario,

 

Correct, although the SR-1 has two receivers (a batch of SR-1 provided via GEO had only 1 in order to save costs), only one can be used. Amongst others the RX transport filters (8 in total) are shared between receiver 1 and 2, limiting the use of the second receiver for Eumetcast purposes.

So you either use two separate receiver units if you want to get both T1 and T2 or alternatively you can opt for the TBS 6903 (or similar), which does have two fully functional inputs available. Having an LNB with multiple outputs is certainly a good way to go, but you could also use a splitter as David does.

 

Cheers,

Ferdinand

Subject: [MSG-1] LNB to receive hvs1 and hvs2 simultaneously and SR1 enable 2nd RX input

 

good morning to all.
I have read that to receive the 3 eumetsat services at the same time it is necessary to have at least two receivers: one for BAS and HVS1 tuned to transponder 1 and one for HVS2 tuned to the transponder 2.
I understand that the SR1 receiver purchased through GEO, at the time of the transition from DVB to DVS2 it does not have the second input enabled and therefore, as a second receiver, a second physical RX would be needed.
So I ask myself two questions:
FIRST: is it possible to enable the second RX on the SR1?in case...how?
SECOND : I read that a valid LNB is the INVERTO ULTRA LNB and I was wondering if, replacing my old LNB with only one output with the new LNB with two outputs, I could receive both transponders at the same time.
Thanks to anyone for the support

Mario
