With the advances in EM simulation SW and computing power the last decade in mind: SES Astra knows exactly how the new bird is performing. There are a number of up-link stations across Europe that can be used to verify the performance. -> Correlate these professional measurements to the...

I Googled it: -ttp://constantinmedia.com/sat/DishSizeMaps/astra-2f/uk-spotbeam.html

I have seen this map earlier. The problem here is that it's difficult to get a feeling about the credibility of the data. I need SNR, in dB or % relative to threshold, with time stamp. I base my reports for Germany and Austria mainly on a huge thread on forum.digitalfernsehen.de The footprint...

Original link to the Map: -ttp://goo.gl/maps/oD42X This started out as a pencil drawing last Friday - and developed trough the weekend. Adding Germany and Austria the last days is quite interesting... I have no idea how deep the 1st null across Denmark and Norway is, But 10dB SNR with an Andrew...

Update today - Astra 2F has changed orbit and improved reception in Bergen. Reception at 20:45 CET: 10964H: 80% / 50% 10994H: 80% / 50% 11023H: 85% / 50% 11053H: 80% / 60% 11127V: 85% / 60% Picture on Channel five is now without breakup.

I have finally got an idea of how bad the SNR goes on a 0.7x0.8m dish in Bergen. (Inverto Ultra Black LNB + Humax Foxsat HD) 10964H goes down to 40% quality in the evening (clear sky). -> The picture is pixelating, but not completely lost. The threshold for DVB-S QPSK 22000 5/6 is close to...

I did a few tweaks this morning: Added LNB umbrella for the rainy days to come. Added 13dB attenuation to try and limit co channel interference from the surrounding 1N TPs. Minor azimuth adjustment of the dish. This is the signal quality measured today: This is very similar to my reception...

I had the same problem before I managed to lock and save the two BBC HD test channels. The new TP (11023H) is saved only when the channel search is completed sucessfully.

I wonder if this is a deliberatly move East, or rather the bird's remaining "wobble" after the speedy move to 28.2E. Let's wait and see if the beam moves West in the evening.

11023H: Currently 80% quality in Bergen - Best ever! (although 1st lock was 13:00 - 18:30 yesterday - and have done some minor tweaks this morning).

I've done further tuning after loss of signal earlier today. The dish has now got one single LNB and I don't think it's possible to get it any better with the signal meter on the Foxsat (not the PVR version). -> I can see the TV from the dish. LNB skew is also optimized - and makes a huge...

80% was initial fine tuning on 2A south beam (11720H). Then 2F came in (just about) at 50% quality. I have done some more fine tuning and have seen 70% quality on 2F

No - the dish has been moved this summer and is not as fine tuned as it was before. Using 1N for fine tuning is far from ideal... 80% quality on 11720 on 2A is equivalent to 50% qualtiy on 11023H at my location. -> Then it was possible to save the two BBC HD channels. With further tuning I'm...

Finally - I found signal on 11023H here on the west coast of Norway :D. It is light rain at the moment, and I need to wipe the raindrops of my dish to keep the signal quality at 60%. -> Picture is gone at 50% quality. The dish is 82x72cm with the LNB slightly off center on a multi LNB rail. I...

The antenna details in the "launch_kit_203_1_2.pdf" document is different from the info on the astrium page: _http://www.astrium.eads.net/en/programme/astra-1n-responding-to-demand-for-digital-and-hd-telecommunication-satellites.html "The spacecraft will have three deployable antennas with...
