Express AM7 (40.0° E)

[Archive-8]

@Captain Jack i know @Llew was also going to try his cband lnb out today on his 1.2 gibertini.

Not seen anyone in the UK get this sat yet.

 

[Captain Jack]

pride21 in Isle of Wight is receiving this with good signal on his 1.5m and, as I mentioned a bit earlier, a successful reception on Triax 110 in London. Is your sat-card seeing any signal there?

 

[Archive-8]

I take that back.

I am just scanning the sat with my Dr HD d15 and got 8 TV + 4 radio. 7° degrees offset.

 

[Captain Jack]

Yay!

They have increased power of 3675H+V tps today. The signal is stronger for me too, now I can lock it with 6.5 db signal level on 110 cm (C-band LNB shifted from focus point).

P.S. In daytime they have tested each transponder with maximal power. So we have not the maximum at the moment.

 

[Llew]

Scan on this sat with the Gibby 1.2.

Not sure why Cultur R+Mayak and Orbita 4R don't resolve.

Also I need to check the T2-M1 TP's with 4T2 Content Analyser.

 

[Captain Jack]

I might stick a C band LNB on my 90cm Fibo and see what I get.

I might stick a C band LNB on my 90cm Fibo and see what I get.

Would you need a new feedhorn or would you just stick on a C120 C band lnb to the original feedhorn?

 

[Captain Jack]

I will modify the C band feedhorn, something like this - https://www.satellites.co.uk/forums/threads/c-band-on-fibo-120.157748/ (without the fancy rotator, of course!)

3615 R 10.0 db
3635 R 10.1
3665 L 7.9
3675 R 8.6
3685 L 9.5

with TM-5402 HD M3.

 

[Laser]

Be good to see some KU band here in Europe to see how reception is...

 

[zorbua]

Couldn't lock 3665L and 3685 L. The other three ok.

It seems to me that the Russians are still doing tests carrier on Express AM-7 !?I found one at 11449 H.I hope to be confirmed by other enthusiasts.

 

[hvdh]

11449 could be the beacon of TürkmenÄlem, passing by right now at 40°E, on its way to 52°E.
Marcus_21 reported that today!

 

[tempo]

There is carrier 11449 H atm indeed. This morning I hadn't that carrier when moved the dish to 43.5°e position.
Few days ago there was similar carrier on 11040V within one hour.
5 db by RF scale is too much for telemetry. It is a test carrier with variable power.

Well fwiw I'm on target ...but still no lock on anything for me ..
Yes I'm fairly close to the troublesome tree ...which is starting to leaf ..
but I would have expected something on the strongest vertical transponder since its qpsk ..
Wildly varying signal max about 5.4db ..dropping away almost completly to -10db ...and back again within seconds..
Personally I suspect the same problem that has prevented me from EVER locking anything from yamal at 49E or Azerspace at 46E ...
I could blame the TT ..but even in winter this chunk of arc is a no go for me..
Some kind of interference blocking I suspect ..and it covers an area coincidental with the tree ..
from abot 55E to 36E ..in C band
I call it 'the dead zone'
cest la vie..

Well ...
I finally got a result from AM7 ...
No chance of a lock using Christina ...
But tried an ESX241 on Carl at least 10 degrees off focus...
still got a variable signal ..but peaking around 6.5db
replaced the ESX with the C1PLL ...and the signal became more stable an consistant around 7.4db peak ...
and thus the F15 locked the strongest mux 3675R ..
I guess I'm very fringe for this one with such a high SR..and the PLL is better suited to maintain this lock.
Plus Carl being slightly further forward can see a little further round the troublesome tree..
anyway ..a result is a result.

Nice. Doubt there's a chance of it on a 90cm Fibo

 

[Vipersan]

Nice. Doubt there's a chance of it on a 90cm Fibo

That would depend CJ ..
C1PLL at the focus ...accurately set up ...
you'd be looking for a signal over 6.5db ..
and of course location and clear line of sight critical.
remember I'm getting 7.4 on a 1.5m offset with the lnb about 10 degrees off focus (possibly clipping a tree)...which I'd estimate to be losing me about 1 to 2db..
The only way to find out ..is to try it.

Replaced the dielectric plate with an adapted offset T plate ...and gained another 1db

3675R now a healthy 8.4db
