[UK-CONTEST] Why do UK stations not beam to OZ in UKAC ?

[Rob Harrison]

David,

I've rising ground up to 100m to my NW, much of where the UK is, but still 
work into GD,GI & GM. It's a struggle sometimes, but VHF is mostly, you're 
not going to get 59 QSO's 90% of the time.

BTW I can hear OZ1ALS now anywhere between 41 to 55 with AS enhancement.
