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.
