Anyone know what UHF frequency Sky use on their RF modulators in Auckland that they provide customers for RF distribution out of the Sky box.

I have a couple at home I use to 're-broadcast' Sky and a DVD player round the home.

The Sky one (my own modulator) was set on ch39 but now has interference on it following the re-stack.

I know I could select a channel by trial and error, but thought I could jump straight to the one Sky use in Auckland.
