I am trying to receive channel 7 and 9 without luck.

Based in Tauranga

I have a 90cm dish on a motorised system and can get ABC and SBS on Eutelsat 172B in good weather which according to Lyngsat should have a lower signal strength.

I can get the feeds on 12593, 12603 and 12609 sr 7200

LNB is Starcom dual LNB 9750/10600 noise figure 0.3 dB

Dish size is 90cm

Are the Aussie transponders using less power output than other transponders on this satellite requiring a slightly bigger dish, I can only go upto 120cm as supported by the motor.

Do you mean Intelsat 19?

Got a multi stream tuner?

The issue is 16 APSK Fec 8/9 needs a lot more signal for pictures. A 90 is to small

is the issue with FEC 8/9 as FEC 4/5 on the other sat seems fine both are 16 APSK

For the ones on Eutelsat you need a CN lock of 11.0
For the ones on Intelsat19 you need CN Lock of 12.9

The 90 is too small,

Gidday Numberonekiwi.

I'm over in Whakatane. A 90cm definitely will not cut the Mustard,

We're viewing it on a 4m which I'm using on both C and Ku Band and are resolving on average 19db - and still see it breaking up with slight Clouding.

Id say a 1.8m would do the Trick easily.

If you can - Try and avoid running the IS19 dish via a Multi switch as you will only introduce more errors.

A mate over in Thames Coromandel has it running on a 1.2m Prime Focus Dish that Resolves IS19 Ch7/9 - But is sketchy. He's a spent a lot of time optimizing his LNB and Scaler rings to suit - so is next level.

It is the high 8/9 Fec and Symbol Rate that makes it difficult.

The Mux itself is good to have.
