...why am I having trouble with DW reception on 103W?

DW is the weakest transponder on 103W. I can get it well most of the time. But at 10.0 dB now, it's only 2 dB above minimum lock value. So there isn't much signal to spare when weather gets poor.

I think DW is actually 5/6 FEC so requires 9.4dB, so that's even less of a margin. Definitely a difficult one. I lose it at the slightest rain or even with thick clouds.

I re-scanned and sure enough it is 5/6. That explains why as soon as I hit 9 dB it's gone. Currently at 10.7 dB, so it's just a dB or so above unlock level.

For whatever reason, 103 is my strongest satellite and I've never lost DW. I don't understand why it has such a high SR when the video quality is so bad. Seems like they're overpaying for unused bandwidth?

I'm disappointed that they're decommissioning 103 later this year. It's a lot younger than 99 and that bird is awful.

Is DW video quality bad?

NHK: 1.2 Mpbs 960 x 720
DW: 5.5 Mbps 1920 x 1080
Cozi: 5.8 Mbps 720 x 480
NewsNation: 1.5 Mbps 960 x 720

Visually, DW looks pretty good to me.

What is the bitrate of NTI?

NTA is 1.4 Mbps 1280 x 720. It looks terrible. They must have an upload issue.

So there's still a lot of room for other channels in that mux. Wonder who the intended recipient is and if they'll ever add more channels to it.
