27.5w and 28.2e

[twh]

I have tried to get the tuner configured for these 2 sats but to no anvail. I can get 27.5w working but no signal from 28.2e. The only way I can do this is setting tuner Simple the Toneburst A/B port A 28.2e port B 27.5w. See the attached photo. I read some where on here that Diseqc isn't working would this be the problem? When I change the tuner setup to Simple, Diseqc A/B no channels work. Can anyone help?
