John,

I think you will find that the two designations are:

GMT Standard Time (what we call GMT)
GMT Daylight Time (what we call BST)

Perhaps that's AOL for you!

You will see below, that your post was timed at 10:32:20 GMT today and as I type this the time is 10:23 GMT today.

(IO or AOL is mistaking GMT for BST?

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

Alberto,


Unless your signal level is particularly low, and "Satellite TV splitter"
will suffice.  If you /do/ have a low signal, you could consider adding an
in-line pre-amp.

I prefer to have one receiver definitely in control of the LNB, providing
the power and the 22 kHz switching signal.  For that reason, I prefer a
splitter where there is a DC-pass option on only a single leg.  These seem
to be less common, but here's a couple of examples:

  https://www.toolstation.com/shop/p66100?searchstr=Wideband%20TV%20&%20Satellite%20Splitter%202%20Way

  http://vision-products.co.uk/product/v26-102led/

If you are using a dual-tuner PCIe card such as the TBS 6903 you can connect
the two inputs together internally by software, so you might not need the
splitter at all.

Cheers,
David

It's not as obvious, but I think TP2 is down as well.  Both reported to EUMETSAT this morning.
Thanks to the folk who provide MRTG monitoring - we could do with more especially for transponder 2.

I too have seen a reduction in the TP1 signal since yesterday evening but only about 0.5 SNR. No apparent reduction for TP2.

Keep in mind that I am still experiencing a drop of about 0.5/0.6 SNR in signal which started well over 2 months ago.

At the moment my TP1 and TP2 signal are exactly the same ( about 12.4/12.5 ].

Ian.

Yes, signal down here earlier this morning in SW London.
Not quite sure 'where it is' at the moment owing to my diurnal variation.

Rain on LNB - now that's interesting?

geojohnt@...
 

All,

We had a heavy rain shower this morning as a cold front moved in and my SNR (and link margin) dropped quite a bit owing to large rain drops on the LNB face.

I wrote about this in an article for the GEO Quarterly some years ago having made a 'rain shade' out of a 2 litre  plastic lemonade bottle.
There has been no need for a rain shade in the SE for months now and so I had removed it.

I found gently wiping the face of the LNB gained me 2 dB in SNR - and likewise link margin!

Writing this email I thought was it really a 2 dB increase, seems a lot.
I remembered years ago the increases were certainly more than 1 dB by removing the rain drops.
So I tried to replicate the rain drops via a watering can with a rose using tap water.
And, the water merely produced a uniform wet film across the whole LNB face resulting in an SNR drop of 0.3 dB.

Hey-ho.

Regards,
John T.

Hello Roby,

Ah!
Thank's.

I'll stop trying to squeeze that extra '0.1' dB out of my 1 m dish.

My understanding is that Sentinel 3B data is now on HVS-2 although not available to anyone even on test.

Hello,

I wonder if the EUMETCast user in Trieste could identify the make/model of his/her 85 cm 'diamond' dish please.
You appear to get much higher SNR/Link margin levels than I do with a 1 m offset dish using an Ayecka SR1.

And, what make/model of LNB do you use?

Thanks in advance,
John T.
