From YouTube: 衛星通信をやってみよう！（バーチャル・ハムフェス2020）
Description
JH4PHW 坂井志郎氏
最近ISSのリピータが使えるようになり、衛星通信に興味を持つ方が増えています。今回は衛星通信入門としてどのような衛星があるのか、どのような設備があれば楽しめるのかを紹介した後に国際宇宙ステーションのリピータや低軌道衛星での交信について紹介します。
ISSからのSSTVやスクールコンタクトの信号をハンディ機で聞いてこの強さなら交信できるのではと思った方も多いと思います。この機会に衛星にチャレンジしてみませんか？

Well,,
you
wrote
about
wintering
in
the
form
of
going
to
that
satellite
two
weeks
ago,,
but
I
would
like
to
talk
about
listening
to
the
radio
waves
from
the
space
station.
If.
You
try
to
do
it.
Again,
you'll
end
up
with
stable,
high-automation
control,,
and
there
are
materials
that
you
can
endure,
and
it's
about
that
kind
of
Hollywood
Prato,.
So
there's
a
tendency
to
stumble
over
things
like
that.
So,.
From
the
perspective
of
how
to
go
about
that,
I
would
like
to
talk
about
a
slightly
simplified.
Version.
B
B

Today,
I
was
also
sending
out
radio
waves
from
places
such
as
Kat
and
Singapore.I've
been
on
the
eqsl
advisory
board
since
2001,,
but
when
I
was
on
the
permanent
patio,,
I
gave
it
that
name,.
But
since
I've
come
back
from
my
heart.

I'm,
going
to
say,

Several
pieces
in
it,
and
they
have
a
useful
design
that
makes
it
possible
to
move
light
generals,
so
for
a
long-term
path,,
an
expedition
in
an
oblong
elliptical
orbit
is
fine,,
but
this
is
a
reaction,
passing
near
the
earth
and
there.
There
is
a
Heisei
satellite
that
can
fly
from
the
earth
to
a
place
close
to
the
orbit
of
a
geostationary
satellite,.
But
in
reality
there
is
not
a
single
satellite
that
can
be
used.
B
B
Normally,
it
goes
to
about
geostationary
orbit,,
so
half
of
the
earth
is
visible
as
half
underground,,
so
the
range
of
renewal
is
wide,
and
since
I'm
an
amateur,,
it's
actually
a
geostationary
orbit.
Even
in
orbit,.
It
will
shift
to
various
cities,.
So
the
timing
of
being
able
to
support
most
of
the
earth
is
negative
for
breast
cancer.
It.
B
B
B
B
B
B
B
B
's
a
teru-era,,
but
you
can
get
the
back,
that's
flying
just
above
the
equator,,
so
with
this,.
The
big
part
is
the
rear,
half
and
the
future,
and
the
feeling
of
a
woman
is
1
pole
or
a
dream.
Match.
It
should
be
very
close,,
so
it
can
be
updated,
and
now
in
the
low-orbit
Heisei
period,
Race
44
is
becoming
relatively
popular,.
B
B
B
After
I
thought
about
it,.
This
is
an
excerpt,
but
I
added
this
page,
because
there
is
one
caveat.
The
Heisei
boards
are
written
like
a,,
b,
and
j.
However,.
Although
v
va
comes
out,,
it
is
usually
said
that
there
are
29,
patients,,
29,
megahertz,
or
actually
18
is
the
megahertz
band,,
but
there
is
29
that
uses
the
upper
part.
B
B
Made
by
fma,
it's
okay
to
listen
to
it
as
it
is,
or
if
it's
a
regular
terrestrial
repeater,,
you
can
listen
to
it
as
it
is,,
but
in
the
case
of
satellites,
the
frequency
doesn't
have
this
kind
of
configuration,.
So
you
can
turn
your
tongue
over
and
turn
it
into
that.
Nephew.
This
is
the
relationship,.
So
if
you
send
with
usb,
the
downlink
on
the
receiving
side
is
in
ysb,,
so
it's
overwintering.In,
the
satellite,,
the
uplink
is
set
to
lsb,
and
the
receiving
side
is
set
to
usb..

an

The

is
actually
only
10
centimeters
square,,
so
solar

are
attached
around
it,,
but
the
power
situation
is
very
bad..
It.
B
's
normal
to
have
200,
milliwatts
or
300
watts
of
radio
waves
emitted,,
but
in
the
case
of
the
ISS,
I'm
sure
some
of
you
have
heard
of
it
on
school
contacts,,
but
even
with
Mobil
Whip.
Actually,.
If
you
come
close
to
59,,
you
can
hear
it,,
so
the
reception
itself
is
very
easy,.
So
on
the
contrary,
it
's
that
loop

button.
However,.
It's
easy
to
do.

Yes,.
So
I'll
give
you
a
startup
table
for
Jamri
and
a
little
bit
about
the
startup
software
So,,
how
to
read
the
startup

You
can
see
by
looking
at
it,
if
you
select

for

If
you

on
the

of

the

So,,
if
you
don't
move
the
receiving
frequency
or
auscultation,,
you
wondered
if
it
would
be
easy
to
do.
That.When
Lego-kun
was
in
Singapore,,
he
didn't
have
any
materials,,
so
he
entered
the
main
hall
and
brought
only
the
wintering
alley.
Cable
from
Japan.
Since
I
was
going.
There,
I
actually
avoided.
The

This
is
an
aluminum
bike
for
gardening,.
B
B
Found
out
that
it
can
be
done
with
3
McVay
radix
and
Moere.
I
already
brought
it
from
Japan,,
and
it
actually
has
a
rotation
rotator,,
but
most
of
the
sample
tails
have
rotations
of
10
degrees
or
less,.
So
I
do
n't
need
it
at
all.
Well,.
It
was
set
out
horizontally
as
it
is,
so
now,
I'm
from
Tokyo,
right.
B
Is
that
the
limited
time
is
10
to
20
minutes.
I
think
it
would
be
better
to
pay
attention
to
the
fact
that
there
will
be
a
lot
of
people
and
places,,
because
there
will
be
more
than
6
races,,
so
I
think
it
would
be
better
to
carve
it
on
the
original
car.
It's
going
to
take
a
lot
of
time,.
So
it's
written
that
we
should
go
to
the
space
station
and
check
the
activation
table
earlier,.
But
when
I.
