Hello
receiver HUMAX TN5000HD motorised dish 90 cm

I have a issue on Badr 4 à 26.0°E

For some time I no longer receive the:
TP 19 12073 H DVB-S2 27500-3 / 4 8PSK
TP 23 12149 H DVB-S2 27500-5 / 6 8PSK

On the other hand, I receive very well the next TP such :
TP 18 12054 V DVB-S 27500-5/6
TP 21 12111 H DVB-S 27500-3/4

I assumed, for a moment, that my receiver was down and could no longer receive TP in DVB-S2 8PSK ?

But by checking on Astra at 19.2 ° E I receive very well TP in DVB-S2 8PSK such as :
TP 2 11229 V DVB-S2 22000-2/3 8PSK
TP11 11362 H DVB-S2 22000-2/3 8PSK

Do you have a clue why I do not receive any-more these TP in DVB-S2 8PSK on Badr 4 à 26.0°E ?
Thank you for your help
Pleasure to read from you.

You need much more signal to receiver DVB-S2 signals with fec 5/6 compared to 2/3

FEC.gif

Your sgnal is marginal to begin with, and the higher fecs push the receive level over the "digital cliff" That 3dBW increase between fec 2/3 and 5/6 means you need double the signal!

You might get away with a bigger dish.

Thank you very much for your prompt reply.
You are right my signal on Badr 4 is marginal....and according to your board I would need at least 7.91 dB C/N ratio .
That explain why the reception of TP DVB-S2 8PSK on Astra at 19.2 ° E is correct ...the signal from this satellite is much stronger ...and indeed the C/N ratio.
Before purchasing a bigger dish I will try to gain some dB by adjusting my present dish .
Thank you again for your skill and kindness.

I used to get 12073 H until they changed to DVB-S2/8PSK MPEG-4,
3 other transponders have also gone here are my latest readings.

Badr-4 @ 26 east transponders with a 104cm Gibertini dish + TM5502HD
MPEG-2 for SD MPEG-4 for HD - DVB-S & fec 3/4 except where stated

11907 H 4500 QPSK 3/4 = 45% data stream
11938 v 27500 5/6 = 63% S.Quality
11958 H 27500 5/6 = 53%
11977 v 27500 5/6 = 83%
11995 H 27500 1/2= 86% (other charts suggest fec 3/4 ?)
12015 H 27500 = 65%
12053 H 27500 5/6 = 80%
12073 H 27500 8PSK = 24% No lock
12092 v 27500 5/6= 61%
12111 H 27500 = 52%
12130 v 27500 = 54%
12149 H 27500 8PSK = 26% No lock
12168 v 22000 QPSK DVB-S2 = 72%
11182 H 16200 = 44%
12225 H 27500 = 57%
12245 v 27500 8PSK = 27% no lock
12523 v 27500 = 65%
12523 H 27500 = 80%
12562 v 27500 = 68%
12642 H 27500 5/6 = 81%
12683 v 27500 = 69%
12692 H 1100 QPSK 5/6= 84%

As Analoguesat said a bigger dish may get these transponders.

Hello Analoguesat and william-1

I have adjusted my dish especially in elevation and the result is quite good

The signal has increased from 63% to 85% on the receiver scale "Quality "

I don't know the relation between this indication and the real value of the signal in dB ?

I receive now the TP 19 12073 H DVB-S2 27500-3 / 4 8PSK and all other TP in DVB-S2

Thank you very much for your help .

10730H 30000 on 26 east. Flysat says this is on Es'hail 2. If I move the dish slightly this becomes much stronger and downloads fine. 50%SQ on the 1.2 dish. I was wondering which satellite this is on???
Lyngsat shows this on one of the Badr satellites
