Description
All of Open Research Institute's live demonstrations from DEFCON 30. Exhibit in @RF Hackers Sanctuary
A

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.

the
open,

development
team,
open

so
it
runs
m17.

transmit
on

I'm
receiving
on
this

receiver.

Hello,
everybody
I'm
michelle
thompson,
w5nyv
and
I'm
here
to
tell
you
all
about
what
open
research
institute
is
and
what
we
have
been
doing
open
research
institute.
Ori
is
a
non-profit
research
and
development
organization,
which
provides
all
of
its
work
to
the
general
public
under
the
principles
of
open
source
and
open
access
to
research.
D
B
We
say
that's
not
good
enough,
so
we
created
a
system
which
we
call
opulent
voice
because
it
uses
that
opus
vocoder
current
state-of-the-art,
very
commercially,
viable
vocoder,
which
has
a
broad
range
of
bit
rates,
supported
we're
actually
at
the
lower
end
of
its
bit
rate
range
at
16.
Kilobits
per
second
16
versus
3.2
is
still
a
big
step
up,
and
this
demo
is
actually
doing
that
over
the
air.

Uses
it
here
at
def
con
I've
mostly
been
very
impressed
with
this
audio
quality.
It's
not
100,
perfect,
not
cd
quality,
but
it's
really
really
good
voice
quality
on
audio.
This
is
what
ham
radio
ought
to
sound
like
today
and
we
hope
to
incorporate
that
into
our
satellite
system
over
the
next.
However
long
it
takes.

B
This
is
one
of
many
technologies
we're
using
to
get
toward
the
satellite
system.
We
have
a
poster
over
here
that
describes
an
authentication
system
for
the
satellite
system.
Another
poster
over
here
that
describes
important
regulatory
work.
That's
been
done
to
enable
development
of
this
satellite
system
in
the
open
with
international
cooperation,
and
there
are
many
other
pieces
of
technology
there
either
we're
developing
or
we're
finding
other
open
source
sources
for
including
propulsion
and
three-axis
orientation
of
a
small
satellite.
