brought 4 modulators, (Satlink st 6503 dvbt) over the past few years and done a update on one recently and cant get the new settings to work.

Have installed before and had working before update, but didn't have all these extra settings before the update.

need to know settings for NZ tv:

constellation

bandwidth

carrier

guard interval

code rate

currently work in Palmerston North as a aerial technician and have 3 dvbt modulators working with freeview fine

also have adjusted output attenuator, checked signals with meter, look fine. 

any help is welcome
