Just Sharing This New French Multi-Stream @ 5°west

[Lazarus]

Swapped the LNB and all is well. Another mahoosive TP

 

[Stevenvc19]

Whilst I had a clear sky today, I measured for the 12648V transponder 16.2db whilst for the 12732V only 13.8db
now with heavy rain I measure for 12648V: 12.8db and for 12732V 12.2db

how is this possible? Is the new frequency more ”water resistant“? Can someone explain this?

 

[ozumo]

Perhaps the reason 12733V on 5W appears to be weaker than other transponders is because of interference from the nearby 12739V on 3W, which is also strong. When it rains the interference that affects 5W 12733V is reduced.

Thanks! that could explain it!

Now then: Having changed a generic el crappo LNB for my ancient Black Ultra and then achieved success with 12733, I've done a bit more experimentation and discovered that the critical factor is not skew, nor is it LNB sensitivity, but the axial position of the LNB. Gotta love the long neck on the Invertos.

Do you have some pictures "before - after" to let us see the difference in LNB position and the associated signal gain?

No. But the old LNB was clamped halfway along it's short neck. I fitted the IBU same, same but still had little joy. Moving it half an inch further away from the dish brought it in loud, stable and clear without degrading the other MTS outcomes.

To complicate the exercise further, in the midst of initially pratting about with getting that TP yesterday, I suddenly lost power to the motor and LNB - assumed I'd had a DiSEqC switch failure but kept getting rained off. In between showers (and more!) today, I found the actual problem was total disintegration of the sheath of the cable from the switch to the motor. It had turned to powder and there was almost nothing left of the sheath. Stripped it back three inches and remade it. Nay bother.

But the odd thing is that the switch is in a waterproof outer enclosure, which leads me to wonder if some sort of galvanic action has been going on. Who knows.

Cheap aluminium-sheathed cable maybe? - that would probably corrode if the enclosure got cold enough to allow condensation to form inside, or maybe the enclosure is "weatherproof" and but not actually "waterproof"?

BTW: when I bought the EMP-Centauri 16-1 DiSEqC switch that's now down the garden, I took it apart to have a look inside, concluded that (when fitted into the outer plastic rain cover) the actual metal enclosure might be sort-of "weather proof" but certainly not "waterproof", and so humid air can get inside quite easily. Therefore I put a couple of silica gel bags on top of the PCB before I reassembled that metal enclosure (worked, so far!).

Here's what the signal difference looks like between Eutelsat 5 West A (inclined) and 5 West B(spot Transalpine).This is why DATA transponders(sr 34284 Ks) are placed on Eut 5A,which costs less for the provider,I guess.
If I am wrong,please correct me

Finally got a chance to check now that it's a clear day. Signal is hovering around 58%, which on my box is a little bit too low to lock for such a high FEC. On the duped transponder I get about 70% on a good day.

 

[Gladstones]

11509 @100%
12648 @95%
12733 @92%

11509 and 12648 stay same from 5 to 5.5 w
Though 12733 @ 5w zero signal
12733 @ 5.5 W 92%
Signal starts at 5.3 W till 5.6
Astra19 try this
Are you able to edit satellite positions in your box

 

[astra19]

I can fine tune, though even at its strongest it’s not enough to lock. The drop off is similar between the two TPs, except it’s from 70% to 60%. Hope it’s just some testing and it doesn’t move permanently!

Is your line of sight clear

 

[astra19]

It is. I’m a bit further west than you so maybe that with the slightly smaller dish is making it too difficult.

 

[Gladstones]

Astra19 try another receiver maybe tuner in your receiver is not powerful/sensitive
Your signal is too high strange it’s not getting lock.
do you receive 12130 v on badr4 @ 26 east ?

 

[astra19]

So I've optimised my USALS settings to get the best reception on the existing French multistream. When I scanned for the Dubai channels on Badr it was too weak, but if I changed my USALS settings slightly I was able to get it (albeit at 30% quality and a little pixelated). I suppose that indicates something might have gone wrong at installation, because now I have Dubai One but no French stuff!

I tried to edit the location of the satellites (Blackhole on Vu+ Duo 4K SE) and it wouldn't let me scan any satellites where I edited the position.

I'd try another receiver but my other one isn't multistream. It would be easier on something else because as far as I know on my receiver you can't fine tune per satellite, which is a real pain. On my old cheapo box it was a lot better to set up with the motor even if it was a bit more labour intensive. That's how I knew I could get Dubai One as I'd had it on my old box. Maybe I shouldn't have "upgraded".

which lnb you are using

badr4 is stronger @25.5 east signal is 56%
5w is stronger @5.5 west
rest of the arc is perfect on their orginal positions on my setup
sounds like vu+ is lacking on functions / limits on software

 

[astra19]

Yes when I look into the settings the locations are set by group level and not individually for the cluster, which can be a pain if the signal is marginal like this. It does seem like I'm out of luck for French Multistream though.

I'm using a technomate TM-2.

try inverto black ultra single 13.79 @ebay
i have technomate lnb which decreases the signal on weak tps by 10-15%
dont give up i am sure you will get there
