Hi Richard, most boxes, I believe, start to break up at about 7.5dB for SD FEC2/3, A little higher for HD. As FEC goes up, ie. 5/6 you need more SNR. If your box works as low as 6.1dB, cherish it and buy another if you get the chance!

Thought all boxes running Enigma 2 would be about the same...it's a Gigablue Quad

No.
Each receiver is different, each has its threshold.
Apart from being an HD or SD channel, we could say we have two tuners, one DVB-S, DVB-S2 the other and each has its minimum threshold signal/dB before pixelate the image.
Normally the channels are in HD DVB-S2, but it is good to remember that this position 28 East has HD channels DVB-S, an example we have with RB BBC HD is an HD channel in DVB-S (12.422H27500).
SR high normally not have problems with any tuner, with low SR, depends on the minimum DUO2 VU + 2000 (confirmed by technical service), the DB800S-HD can tune radio channels with SR 300 and video up to 1000.
If the SR is very very low (300-1500), we need more same signal antenna for "apparent" in Hispasat with 50cm spare, for these channels, 100cm motorized antenna must be tuned to the satellite at 100% or not the smells.I leave a link to a comparison between two tuners so that you see your threshold signal level, Dreambox800S-HD and VU + DUO2.
-----------------------
No.
Cada receptor es un mundo, cada uno tiene su umbral.
Aparte de ser un canal HD o SD, podriamos decir que tenemos 2 sintonizadores, uno DVB-S, el otro DVB-S2 y cada uno tiene su umbral minimo de señal/dB antes de pixelar la imagen.
Normalmente los canales HD estan en DVB-S2, pero es bueno recordar que esta posicion 28 Este tiene canales HD en DVB-S, un ejemplo lo tenemos con BBC RB HD, es un canal HD en DVB-S (12.422H27500)
Con SR altos normalmente no tendras problemas con ningun sintonizador, con SR bajos, depende, el VU+DUO2 minimo 2000 (confirmado por servicio tecnico), la DB800S-HD puede sintonizar canales de radio con SR 300 y de video hasta 1000.
Si el SR es muy muy bajo (300-1500), necesitamos mas antena para una misma señal "aparente", en Hispasat con 50cm sobra, para estos canales, la antena motorizada de 100cm tiene que estar afinada al satelite al 100% o ni los huele.
Dejo un enlace de una comparacion entre 2 sintonizadores para que veas su umbral y nivel de señal, Dreambox800S-HD y VU+DUO2.

Que umbral de señal/SNR tiene tu deco.? es importante.(14-2-2014)

Can anyone help me out?
Just checked 12422H for the tennis coverage on the Red Button. Flysat puts it on 2F UK, Kingofsat on 2E Europe!, either way I´m only receiving 7.2dB on the 1.8m Fam. I get 10.5+dB on all other UK beams on 2F 2E etc.
Could be my LNB is just weak on this frequency.
Anyone else noticed anything wrong on this txp?

& Lyngsat says 2F eu. Levels on 12422H very weak here in the north too, receiveable just 'now and then'. For example 12207V is immensely stronger.

I didn't think it was eu always thought uk, but why so much weaker than other uk txps?
Maybe higher frequency struggling more?
.
You have important differences in level between 10.773H and 12422H.
Very good joke footprint Europe.

Muy bueno el chiste de huella Europa.

10.773H22000.- 8'50dB, SNR 53%
12.422H27500.- 6'00dB, SNR 37%

Some pictures of a few weeks ago, same levels now/Unas fotos de hace unas semanas, mismos niveles ahora (6811 => RB BBC HD).

That is conclusion I have reached. Strange though, for some reason I thought higher frequencies would pass through the atmosphere better. Must have mis remembered my physics!

It appears I was wrong about the VU SE receiver limit. Although BBC News HD breaks up at 7.8dB, the red buttons are working fine this morning at 6.8db.
I also noticed Tururu gets a picture at 5.5dB

These are some findings from Southeast Mallorca using a 1.8 Prodelin with IBU quad, I've not tweaked my system for sometime, as access to the roof is difficult during the summer months, I will have a go when I am here later in the year, but right now I'm getting everything 24/7 that we want to watch, so no major concerns till the skies go grey !

The upcoming changes are important.
These changes are not important, just clear the Eutelsat 28A by the problems that have to be expired for years.
The changes will be in late July, then began the beginning of the end and allocate While tp's.
Channels / tp's to the footprint / European beam and channels for the print / bundle only for UK.
Apart from a possible change in the general position of the satellites 28'35 ==> 28.2, but that said, in late July will leave doubts, now says speculation as a partner.
In the Spanish part of the forum, leave a daily report (if I can) levels by Madrid.
-----------------------------
Los proximos cambios son los importantes.
Estos cambios no son importantes, solo dejar libre el Eutelsat 28A por los problemas que tiene al estar caducado desde hace años.
Los cambios seran a finales de Julio, entonces comenzara el principio del fin y asignaran bien los tp's.
Los canales/tp's para la huella/haz Europeo y los canales para la huella/haz solo para UK.
Aparte de un posible cambio de la posicion general de los satelites 28'35==>28'2, pero lo dicho, a finales de Julio saldremos de dudas, ahora especulaciones como dice un compañero.
En la parte española del foro, dejo un reporte diario (si puedo) de los niveles por Madrid.

PS For me, this is the fun part of fishing satellites/Para mi, esta es la parte divertida de pescar satelites.

5.5dB is the value DB800S-HD tuner, but it is not the worst, depending on the SR used by tp without pixelation to 4'5dB.
With many pixelations with 4dB signals.
The VU+DUO2 tuned better and not pixelated on the same terms

When I have time I will take one of the dishes out of line to find the cut off point. The Emitor tester will lock on 4dB and still have good picture

Although BBC News HD breaks up at 7.8dB, the red buttons are working fine this morning at 6.8db.
Depends on system, modulation, and FEC. Both are 2/3 FEC, but red button is QPSK, whereas BBC HD's are 8PSK. For any given FEC, 8PSK requires about 2dB more SNR than QPSK.

Thanks H. I know we have discussed this and the fact that the higher FEC´s need more signal but I couldn´t remember which thread it was.
Assuming the SE receiver quality is the same it should work down to about 5.8 on QPSK FEC 2/3?

Theoretical is about 4.4 dB for QPSK FEC 2/3. In practice should easily work down 5dB. But remember what it says on that display could be way out.

I´ll let you decide, when you fit the motorised dish!
