Ø is really a Nordic O slash. For a true slashed zero -- see URL:
http://www.reference.com/browse/wiki/Slashed_zero

The slashed zero looks just like a regular letter 'O' or number '0' (zero),
but it has a slash through it. Unlike the Scandinavian vowel 'Ø' and the
"empty set" symbol '?', the slash touches the walls of the surrounding O
shape but does not extend past them on the outside.

In Ham work I use the Nordic O Ø for call signs, but be aware this can
goof up some logging programs
