Description
Using a TNC3 or Nucleo TNC for M17 Protocol.

Hi
folks,
this
is
rob
wx90
with
mobilelinked
and
what
you
just
heard.
There
was
an
example
of
m17
a
digital
voice,
so
in
this
video,
what
I'd
like
to
do
is
describe
m17
real
briefly
and
then
kind
of
showcase
how
anyone
can
get
on
the
air
with
m17
today
using
some
of
the
the
tools
we
have
in
front
of
us,
and
then
you
know
some
of
the
other.
Give
you
a
little
brief
overview
of
some
of
the
other
news.
A
That's
going
on
in
the
m17
world
right
now,
so
m17
is
a
digital
voice
mode
designed
for
vhf
uhf.
Well,
one
of
the
great
things
about
m17
is
we're
using
a
an
open
source,
codec
codec2
for
the
voice,
encoding
that
allows
experimenters
amateur
radio.
Experimenters
like
myself
to
you,
know
design
systems
like
this.
That
would
be
difficult
or
impossible
to
do
with
or
extremely
expensive
to
do
with
a
proprietary
codec.
A
A
So
what
you
saw
earlier
was
me
using
my
android
device
here.
Basically,
as
a
glorified
speaker
mic,
so
it's
using
the
microphone
to
read
in
the
audio.
It's
converting
that
it's
using
the
codec
2
vocoder
to
encode
that
it's
connected
to
a
tnc
3
via
bluetooth,
low
energy
and
it's
sending
the
data
via
kiss
packets,
similar
to
what
you
would
do
with
like
sending
data
packets
from
aprs
droid
over
to
the
tnc3.
A
The
tnc3
is
handling
the
baseband
modulation.
So
it's
doing
packetization,
forward,
error,
correction,
4f,
sk
modulation
and
that's
being
sent
into
9600,
baud,
capable
radio
and
then
what
you
heard
was
the
audio
being
received
by
or
the
the
over-the-air
fm
being
received
by
an
rtl
sdr
being
demodulated
with
rtl
fm
and
then
passed
on
to
the
m17
demodulator
for
baseband
demodulation,
which
is
then
and
also
codec,
2d
coding,
which
then
entered
into
the
audio
system
of
my
of
the
computer
off
screen.
A
A
A
A
A
A
But
with
that
what
I'd
like
what
I'd
like
to
do
is
invite
you
to
join
us
on
the
m17
discord
channel
and
and
participate
with
us.
There
there's
also
an
m17
forum
that
you
can
that
you're
welcome
to
to
interact
with
on
the
discord
channel.
Most
there's,
usually
someone
there.
You
know
24
hours
a
day
these
days
and
either
can
answer
questions
or
point
you
in
the
right
direction
and
in
the
show
notes
below
I'll
link
in
how
to
get
the
android
software.
