Astra 2F: European Beam Transfers Starting?

[Schroeder]

More info from SES on Facebook:

SES <span><span>Hi Priit, There has been a couple of channel shifts including to ASTRA 1N to optimize the use of our fleet at 28.2 degrees East. These should be completed now.</span></span>

<span><span>Confirms that not all transponders moved to 2F, some have moved to 1N as well.</span></span>

Interesting, so now it gets really confusing. ;)

And assuming of course they are not talking about the original 1N UK spot transponders...

Confirms exactly why I have repeatedly urged caution over swallowing what SES-Astra's PR people say!

Some of the reports from the Canaries show transponders weaker than others, I guess Sky News (12207V) is now on a 1N Txp. Was this previously on 2A or 2B?

I had it down as 2B South in my records but it could have been 2A South too for all I know. The 2A and 2B transponders varied a little depending on if you looked at KOS or Lyngsat...

from merely a practical aspect ses can argue that these changes have not affected the viewing of the intended audience, hence the lack of communication. however, i feel that european viewers of fta channels like sky news or pick tv are perfectly legitimate customers of "your satellite company", and deserve to know what happens with the service they use. a casual, indolent comment on facebook is a far cry from what you'd expect from a major international corporation - very unprofessional.

The only thing we could be fairly sure of is that the 2B isn't active at 28.2 anymore.

Totally agree, it is rather disappointing.

This is the way it should be done:

I am confused myself now. Sorry.

Try going back and reading the posts and scans from a scientific point of view, and forget about ramblings on Facebook pages or other nonsense posted on satellite websites.

If you look at the scan posted by "oldfart" in the Canaries (post #294) you will see 1N spot (10700-10950) is an easy catch, as well as 1N PE beam (11005V & 11185V), where as 12207V is down in the noise, i.e. it is not on either of those beams. 2F spot is also moderately strong on that scan and obviously a different beam too.

Now compare that to the scan from "strs65" in Crete (post #299). 2F spot stronger than 1N spot. 1N PE stronger than 2F spot. And 12207V more powerful than all the beams mentioned so far and only exceeded by 2A South (12051V).

My results from this location separate these beams in a similar way but the combination of signal levels is different again.

So 12207V isn't any of the previous & known beams, so can only be on a brand new one.

Posts in the signal reports thread seem to confirm the above... now all we need is for Analoguesat to collate all those reports for 12207V and 12110H into a map so we can make sense of them.

Indeed, FB reports are done by PR with not so much technical knowledge :|

If you look at the scan posted by "oldfart" in the Canaries (post #294) you will see 1N spot (10700-10950) is an easy catch, as well as 1N PE beam (11005V & 11185V), where as 12207V is down in the noise, i.e. it is not on either of those beams. 2F spot is also moderately strong on that scan and obviously a different beam too.

Actually there are 3 beams available on the 1N, The UK beam and two different Pan-European beams. Most likely 11005V and 11185V are on 1N Pan-European beam #2: _www.satbeams.com/footprints?lat=0&lng=0&zoom=1&beam=7105.

Now compare that to the scan from "strs65" in Crete (post #299). 2F spot stronger than 1N spot. 1N PE stronger than 2F spot. And 12207V more powerful than all the beams mentioned so far and only exceeded by 2A South (12051V).

Officially both 1N Pan European beams don't cover Crete. Why couldn't it be Astra 2A North? The official footprint doesn't cover The Canary Islands and Crete but Crete is relatively close to a side lobe of the beam: _www.satbeams.com/footprints?lat=0&lng=0&zoom=1&beam=5595 The question is, could "strs65" receive the 2A North beam already before the switch?

Reports from Finland with no lock, so it couldn't be 2A North.

My bet is that it's on the 1N Pan-European beam #1: _www.satbeams.com/footprints?lat=0&lng=0&zoom=1&beam=7104. This beam doesn't cover Finland and the major parts of Ukraine and the Baltic states. Neither does this beam has a lobe in the southwest (like 1N PE #2) and is closer to Crete than #2. That would explain it.

 

[tothbros]

could it be that 2F PE beam has similar charachteristics to the UK spot beam in that it has a sharp cut off point? remember reception reports of the UK beam where 50-100 km's made a huge difference on the edges?

another thing to remember is there can be big differences in reception of transponders on the same beam...again, in the fringes, of course.
for example, for me, in hungary 1N UK spot has tp's where i get 75% quality, while under 40% for certain others...

i think 2F launched a new era of beam shaping, and it leaves us puzzled. look at the inconsistent reception reports of 2F UK...

It doesn't tie in with 11778V which is know to be on 2A North. Look at the mentioned scans again for that frequency compared to 12207V. And from here 11778V is right down in the noise and completely disappears in the afternoon. 12207V is 24/7 reception.

Yeah I made a mistake. I already edited my original posting.

[skomedal]

The 1N pan european 1 ( PE1 ) footprint does not cover gran canaria, crete or finland so maybe the answer.

Snap :-beer

The email address at Lyngsat is not an official route to SES. It merely directs any corrections to the relevant person at Lyngsat dealing with Astra changes.

I think you might reasonably expect this beam to be recievable in Crete on a 1.1m dish yet its not stable . The beam that ends furthest away from Crete is 2F

1n pe 1 covers all of Greece supposedely with a 1.2m ( , distance as the crow flies to Crete 60kms. The beam shaping is not that sharp especially given its not too far off Axis.

2F has a 1.2m edge in Italy distance as the crow flows to Crete is some 1000km

In either case the supposition would be that the offical maps in some instances are wrong and that the beam shaping hasnt gone to plan for the canaries or that Greece is not aswell served as th 1npe1 suggests. I dont think we have seen any instance of the beam being tack sharp to 50kms , even off axis.

Whats the difference between a 1.1m and 1.2m in db , nada esp if the 1.1 is well lined up with a BU as is the Chania report.

Then there is the report from Paphos , granted out of coverage for the mystery beam , but from a 2.8 , it is of axis but only 1000km from where 1N pe1 supposidly ends .. you might reasonably expect something there on a 2.8 ..yet not a flicker ,, at a rough guess Paphos is 2000km from the edge of 2F PE.

 

[paul gouves]

I'm in Crete and 12207 sig is zero.

 

[Br492]

It is so strange ,I am at western Greece some hundreds km from Chania and with my 1,25x1,40 dish I have healthy 13 dB signal at 12207V
