You have inadvertently chosen a magic symbol for an antenna name and the 
parsers are not smart enough to deal with that.  Since this is a widely 
used parser with lots of generality I dare not make fundamental changes 
to it.  It will be easier to rename your station - e.g. FL or FZ.  Use 
puttab to change the antenna (AN) table and edit the log file to rename 
the antenna (leave its number alone).
