What Peter posted above is indeed the "Latin Capital letter O with 
stroke" character at Unicode position 0x00d8.  It is definitely not 
part of ASCII but is sometimes available as an "extended ASCII" at hex 
D8.

On a Macintosh, you can get this character by holding down the option 
key and typing an uppercase O (oh) (i.e., shift key also held down).  
The lower case version of it is just option-o.

If the ARRL robot does the typical 8-bit input into 7-bit ASCII 
conversion, then this Ø character will appear as a capital X.  So NØNI 
will show up in your log at the robot as NXNI even if it looks OK at 
your end.

In fact, it would not surprise me one bit if some of you see an X 
instead of an oval with a slash across it in the above text if your 
mail reader does not support "extended ASCII."

I am copying Trey on this, although personally I am not sure if he 
should make Cabrillo accept 0xd8 as a zero.
