Where
our
voices
are
nearly
given
out
at
the
end
of
defcon,
the
demo
we
have
here
today
is
about
voice
quality,
digital
voice
quality,
especially
for
amateur
radio,
and
if
you
start
with
what
exists
today,
go
to
the
ham,
radio
store
and
try
to
buy
a
digital
voice.
Radio
you'll
end
up
with
something
like
this
20
year
old
mobile
phone
or
not
mobile
phone,
but
land
mobile
technology.
B
There's
a
20
year
old,
vocoder,
it's
locked
down,
proprietary
patented,
you
can't
mess
with
it
and
it
sounds
like
a
little
robot
in
a
box
just
not
great
voice
quality.
So
the
m17
project
is
a
group.
We
work
with
has
created
a
protocol
of
their
own
for
radios
of
this
type,
which
they're
able
to
replace
the
the
voice
coder
with
something
a
little
more
modern
called
codec2
codec2
is
open
source,
not
patented
licensed
freely.
B
So
it's
available
for
experimentation
and
they
use
it
at
about
3.2
kilobits
per
second
and
get
pretty
good
voice
quality
out
of
it,
and
I'm
able
to
demonstrate
that
voice
quality
by
transmitting
on
this
radio,
which
has
modified
firmware
courtesy
of
the
open,
rtx
firmware
development
team,
open
rtx,
so
it
runs
m17.
I
transmit
on
this
I'm
receiving
on
this
web
receiver.
