Okay,
this
flowgraph
as
written
transmits
from
a
file
source
that
contains
the
raw
symbols,
m17
symbols
they
have
to
be
packed
and
chunked
and
then
filtered
before
they
can
be
frequency
modulated.
The
file
we
want
to
transmit
with
has
already
been
packed
and
chunked
and
filtered.
So
I
want
to
replace
this
whole
stream
with
a
single
file
source
that
takes
a
different
kind
of
file.
