Astra 2F: Scandinavia & Baltics Discussion

[Waveguide]

Having spent some time on the beam maps (from Lyngsat) i wanted to check the
accuracy of the maps using the two sets of data we have from Riga and Linköping.

I have compared the EIRP values from the two cities in each beam map.
(In the Europe beam map it's antenna sizes instead but the same value for both cities
means the EIRP-value should also be the same.)
The difference in the two sets of actual measurements should also show the same
difference if the beam maps are accurate.



Well, Lo And Behold, the match is really good which means the beam maps show
the EIRP just as we have measured it. The "difference between the differences"
is a constant 2-3 dB and can be explanied by the fact that we have different receivers and
I have some extra attenuation from a splitter in the signal path. Add 2-3 dB to the right
column to compensate for my extra attenuation and the numbers will match.

In short, the five beam maps show actual signal levels (in our part of the world at least).

Any different ideas on the difference between differences or total indifference maybe?
(Getting confused here ....)

This morning was the first time that I noticed I was able to receive all the new Astra 2F Euro beam channels without any pixelation, even the weakest one 12552V on a 1.8m dish in Helsinki. Even now as we start to get to the weak period most of the channels are still OK with just occasional breakup.

I've just realised we are in the 2F thread.



Mod. Note: Refers to recent detailed discussion of creating signal graphs for Linux Rxs, which I've now moved here

I'll find a home for it shortly - doing Domestics right now.

I've done my best to maintain continuity both in this 2F Thread and in the new one, but if there are any howlers ................................. Tough!

North Stockholm receptionof Astra 2F 180cm- 60% on the PanE beam 12522V in clear weather, nothing on UK spot

 

[popolon]

From where is interference coming to 10951V, 11142V-11162V, 11196H frequencies?


Are these 10951V+11197H data channels?


and these are normal channels, but from where?

These interferences are seen with 3M and 5M dish. And even with LNB that is only for one polarity and for frequency band 10900-11700 (Norsat 4000C). Also these interferences are seen in Estonia with 2.4m dish:


By the way, where are 2E middle east frequencies listed, or are there no active TPs yet?

 

[Marti]

After success with 2E in the Stockholm area with my CM 2.4M offset dish + Inverto Black Ultra, I have discovered I can also pick up the UK spot beam of 2F - without tweaking (in the evenings only) and all day if I adjust the dish for the difference between 28.5 and 28.2 of the 2E and 2F satellite locations. No HD channels, though. 2G remains a black hole..

CBS action 55209 \ Horror 55202 appearing on 2F, moving away from 2E \ 2G?

= can't get Horror in the evenings, will miss those great movies about teenagers getting trapped in old houses, cut into pieces and eaten by extraterrestrial monsters... what a loss! :O)

I´m watching the Attack of the 50 FT Woman right now, can see why you will miss this!

CBS Reality, CBS Action and Horror are now on 11 344 V (2F) and they will almost certainly leave 2E/2G in the near future. As for the two CBS channels this will mean an improvement for me since 11 386 H and 11 426 V are around 85-86 % and 11 344 V is around 87-88 %.
Horror will of course be weaker since it leaves the 2G European beam for 2F UK.

As from today all channels above left 2E/G and are now to be found on 11 344 V on 2F only.

Indeed. Losing 2f uk in the evenings, a few (crucial) db's weaker here than e\g.
But no reason (yet) to get bigger dish.

Transp 11307 H (& 11385 H on 2E) 'went away' on the solo2, tested and working on Humax and other boxes, so lnb etc must be ok. After a while of scratching my head, tested with changing fec on the solo2, was 2\3, at 5\6 channels came back. Confusion from this side, or has there's really been a fec change on 11307 H & 11385 H ?

btw, on PBS america right now, program about guys going down the Niagara in metal containers. Am suddemly feeling very sane lol

Yes, the FEC changed to 5/6 on both those yesterday. No doubt more channels will now be squeezed in as a result.
