Astra 2E at 28.2E: General Discussion Part 1

[solly]

Cheers, guess Pietclock it's hard to be 100% confident that the 33MHz TP's were tested not knowing the footprint but looking at the 2F testing thread it does look like some differing reports were received for the same TP's, suspect of wide/spot switching. There was certainly wide/spot testing in the C band.

Prefer, you've missed 12480V (TP40) off that list + 11992H (TP9), thought 12285V had migrated too?

1280v still on air
here on mideast only with large 3.5 m can receiver north beam
11992h no signal here
12285v got signal not move to 2e yet

 

[solly]

Yes, pretty sure those are all on 2A still.

12285V is odd, as it looks like a Sky transponder that didn't move.

maybe tonight astra 2a will be empty ?
new game of astra 1n also start

 

[solly]

I check you signalinfo and Sollys post no 312 and:
tp alive on astr 2a
11817v (2A South)
11875h (2A S)
11895v (2A S)
12032h (2A S)
12051v (2A S)
12285v (2A S)
possibly still in Astra 2A!!

all tp alive no change yet
it from south beam
last tp 12480v 2a on north beam

 

[FRINGE]

Can just about get it now. Must be an a.m. thing with my location because 2f was weaker earlier this morning also.

But, as for 12207v, only one of my Humax tuners can receive it with 70% strength and 20% quality. So picture is crap (heavily pixelated).

Gone again.

a516digital reporting bbc channels to move to 2e Thursday am...

Astra 1N is shortly to be moved to its permanent position at 19°East, so the affected BBC services will be transferring to a new permanent home on Astra 2E (28.2°East). This will take place in the early hours of Thursday 6th February 2014.

the 12480v only large dish more then 3.8m to get it over mideast
all tp list on 2a south beam was receiver 1.8m

Down here solly the 12480 V is receivable with a 1.2 Dish....Signal Level 10db

The "IPTV will solve all your ills brigade" are out in force: I've just "removed" (!!) a person who Registered here today for the sole purpose of Spamming our 2E Threads with his IPTV Service.

Fortunately it didn't get as far as open Forum.

 

[M60]

Ohhhh... thats tricky stuff. Switching full power signals makes it very vulnerable to
failing coax relays. Having switches before the final amplification makes things easier.
Combiners are not necessary on every TP then. This assumes the TWT's are wideband and
linear which they hopefully are. Pure guesswork but narrowband combiners are often larger
than ones with wider bandwidth. I've opened some scrapped fancy coax relays and
the autopsy was "interesting".

Anyone got information on the RF system "layout" in these birds?

Edit - answer ended up inside qoute.

Your possibly right in the sense any co-ax switching is before amplification to keep the RF switching level down, would love to know myself.

I did watch the 'How To Build A Satellite' documentary again the other week, when I get some time I'll grab some screenshots and upload them as you'll be impressed.

Cheers too Solly for the info on the remaining Sky 2A TP, this must be uplinked to 2A on a separate antenna hence why it's not migrated.

Gone again.

i got 3.8 c/n north beam astra 2a
very low with 4.5m

 

[M60]

The BBC 2E changes take place Thursday morning from 03.30, set your alarm clocks!

 

[solly]

what i not understand how i get 1 db astra 2e
maybe it spot beam not europe beam
same signal like astra 1n uk beam 0.5db

 

[Pietclock]

@solly: the 2E Europe beam seems to be dropping off rapidly east of Greece.

 

[tothbros]

12480v must be pe beam, because i get a strong signal on it. uk beam is zero for me.

 

[Huevos]

BBC page shows bigger footprint on 2E than 1N and says "the effect on coverage within Europe: Northern France and Belgium may see an improvement, outside of this area there may be a slight reduction in coverage with the need for a larger receive antenna".

it drop drop signal like astra 2f

 

[tothbros]

outside of this area there may be a slight reduction in coverage with the need for a larger receive antenna".

the word "slight" just gained a new meaning for me
i'd be slightly happy if i won the lottery

 

[Acuario]

Atmospherics or secondary effects of 2E being close by?
I just got a call from a customer saying he was receiving C5 on an 1M dish with a SKY HD box - impossible here!
We checked and he had 5* and 5USA as well.. I checked where I am (about 10K away and 1.2M dish) but nothing however I can receive 4seven and C4 HD which has been impossible before. I did a quick scan of 2F and 11128V is reading -67dB, on 1st it was reading -68dB and couldn't be locked...

Normally they are quite correct at the BBC, but this is far from the truth.... the 1N UK "spot" is even stronger than the new 2E/2F Europe Beam here. Hardly a real spot beam. The new 2F beam is MUCH tighter.
