                        The web site doesn't have detailed data, but I
was able to get them to fax
                        it to me.  There is a PC program for computing
the bits to program it, but
                        I have not gotten it.

                        Fox claims the F6053A is discontinued and has no
replacement, which is a
                        shame because it is a really nice part.
