OK, I reread the manual page:
      As  each input record is read, gawk splits the record into      fields, using the value of the FS variable  as
the field      separator.   If FS is a single character, fields are sepa-      rated by that character.  If FS is the
null string,  then      each  individual character becomes a separate field.  Oth-      erwise, FS is expected to be a
full regular  expression.
 

Turns out -F is a regex only if it is more than one character.  Fixed by
changing it to '.'.  Applied.
