A
A
B
Today's
November,
8th
2022
and
we've
had
a
pretty
amazing
week
so
for
the
stand
up,
let's
start
with
z.
You
have
the
floor.
Oh
my
mic's
not
working
today
for
what
it's
well,
oh
dear,
okay,
so
welcome
Z,
and
if
you
want
to
type
then
I
can
read
it
out
into
the
record
or
or
catch
up
on
slack
or
anything
like
that.
I'm
terribly
sorry
about
your
mic
situation:
oh
you're
Sasha,
so
hello,
Sasha,
I
figured
it
might
be.
You
I
have
some
reports
for
you.
B
So
while
you
have
the
floor,
yeah
I,
don't
know
why
your
name
shows
up
to
Z
either,
but
these
are
life's
little
Mysteries
but
yeah.
So
you
were
last
week
we
talked
briefly
about
addressing
the
RF
chain.
So
what
we
really
need
to
do
is
start
looking
at
the
RF,
Equipment,
radio,
frequency
equipment,
microwave
equipment
for
that's
going
from
the
fpga
output
or
actually
the
rfic
output,
like
from
the
from
the
80
9371
that
we're
using
to
start
looking
around.
B
Is
this
the
path
that
we
want
to
stick
with
any
pretty
much?
Any
rfic
is
going
to
be
similar
to
the
9371
in
terms
of
electrical
interfaces
different
in
some
ways,
but
but
we're
dealing
with
digital
equipment
designed
for
space,
and
so
let's
look
at
the
RF
chain.
So
let's
assume
that
you
have
these,
that
you
have
eyes
and
q's
coming
at
you
and
that
we're
dealing
with
a
10
megahertz
or
whatever
we
want
to
to
decide
to
to
implement
for
for
your
team.
B
You
know
so
there's
some
flexibility
there.
Our
flexibility
is
limited.
If
we
stick
to
amateur
radio
sub
bands,
we
have
10
megahertz
to
play
with
for
the
downlink,
that's
at
approximately
10.4
gigahertz,
but
we
talked
about
supply,
chain
challenges
and
there's
some
things
are
just
not
available,
but
assuming
that
we
have,
you
know
we
do
have
several
Labs
with
equipment
that
can
produce.
B
You
know
at
least
baseband
signals
that
are
properly
modulated.
What
can
we
build
and
then
you
have
some
of
the
documents
that
we've
been
working
on
and
some
of
the
designs
I
was
able
to
meet
with
with
Jan
King
on
this
past
Thursday,
and
we
talked
in
that
that
conversation
is
on
our
YouTube
channel.
B
We
talked
a
lot
about
a
variety
of
things
brought
this
up
and
so
we're
looking
for
additional
people
he's
out
scouting
out
folks
that
are
interested
in
in
helping
with
this.
With
this
part,
we
also
went
on
Thursday
to
sbms
San,
Bernardino
micro
society,
and
we
had
some
lots
of
side
conversations
about
RF,
so
there's
some
enthusiasm
there
from
some
people,
recently
retired
from
places
like
JPL
that
will
might
be
able
to
help
us
with
building
more
RF.
B
The
Big
Challenge,
though
just
from
a
brief
15-minute
tour
of
the
world
of
components
engineering,
is
that
it's
not
great
out
there
still
for
for
buying
the
stuff
that
we
need
so
I'm
open
to
suggestions
and
we
are
going
to
have
to
be
we're.
Gonna
have
to
be
Scrappy
and
smart,
and
you
know
agile
and
all
that,
so
it
looks
like
if
you,
if
you,
if
you
have
audio
back
I,
don't
know
if
you
do
or
not,
but
you
certainly
have
the
floor.
B
Splitting
the
okay-
so
yes,
I,
was
thinking
of
splitting
the
Dax
side
of
things
and
the
up
conversion
side
of
things.
Yes,
I
think
that
we
could
do
this
and
should
do
this
and
and
it's
gotten
a
general
yeah.
That's
the
way,
the
way
to
go
yeah,
so
the
rfic
isn't
available.
We
can
have
an
alternate
design
ready
to
go.
B
Yes,
I
think
that
would
be
good
I'll
do
all
that
I
can
to
help
I'm,
not
RF
expert,
but
I
am
ready
to
hit
it
with
a
tire
iron
as
hard
as
I.
Can
yes,
Jesse
204b
is
our
Baseline,
so
we
really
want
that
to
stay
with
that.
That's
why
we
went
with
the
adrb
9371
board
in
the
first
place,
instead
of
picking
something
like
the
the
9361
or
older
design
and
it's
just
very
powerful.
B
The
the
advantages
to
justd
204b
for
those
that
are
listening
are
are,
and
are
more
than
enough
justification
for
dealing
with
the
any
sort
of
complexity
or
weirdness,
and
there
is
some
complexity
and
weirdness
because
it's
you
know
this
is
higher
end
stuff
and
there's
more
things
to
make
sure
that
you
get
right,
which
we've
we
found
out
the
hard
way
several
times
so
and
let's
see
we're,
definitely
avoiding
CMOS
or
lvds,
definitely
set
on
J.
Yes,
so
Jesse
204b
is
our
Baseline.
B
Unless,
unless
we
find
out
that,
there's
some
better
way
to
do
it,
but
that's
that's
the
way
everything's
been
going
and
all
the
advice
from
the
industry,
people
that
we've
talked
to
has
been
to
do
it.
B
That's
why
we
picked
it
in
the
first
place,
so
in
terms
of
like
RF
design.
So
if
you're
sitting
around
with
some
sort
of
ideas
or
parts
or
or
designs,
they've
been
waiting
for
10,
gigahertz
or
five
gigahertz
or
2.4
or
or
24
or
47,
then
now
is
the
time
to
to
share
them
all
right
and
then
then
another
note
is,
there
are
definitely
are
dacs
that
take
just
to
eat
and
it
should
be
enough
to
have
an
alternate
design
to
work
with
around
the
80
rfic,
not
being
a
stock.
B
Yes,
I
agree,
I
would
like
more
hours
in
the
day,
so
that
I
could
be
more
help
other
than
just
knowing
that
but
yeah
whatever
I
can
do
to
to
get
this
to
happen,
because
we
we
firmly
believe
that
it
doesn't
work
until
it
works
over
the
air
and
we
demonstrate
things.
So
that's
how
we
get
things
done.
We
do
publish
papers
and
designs
and
keep
the
repos
up
to
date,
and
we,
we
really
do
believe
in
documentation,
but
complete
documentation
is
not
something.
B
That's
going
to
stop
us
from
building
building
and
testing
something
over
the
air
to
show
that
that
an
idea
works.
So
please
proceed
and
we'll
back
you
up,
100
percent
and
then
anything
else.
If
you
want
to
type
it
in
chat,
then
we'll
okay,
so
I'll
get
started.
Yes,
thank
you
yeah
and
I'll
I'll
start.
B
B
So
thank
you
so
much
for
for
all
the
work
Sasha.
It's
deeply
appreciated.
A
All
right
reporting
from
South,
we
don't
have
too
much
to
report
this
week.
Admittingly
we've
been
continuing
our
efforts
in
setting
up
more
equipment
over
in
our
primary
facility,
but
there's
not
too
much
to
report
just
continuous
work
and
no
major
roadblocks
this
week.
So
far,
oh.
B
Good
good
to
hear
I'm
glad
yeah
I've
seen
the
the
photographs
of
all
the
stuff
moving
around
so
yeah
I
am
as
soon
as
we
can
accept
a
shipment
of
lab
equipment.
B
Then
then
we
we
need
to
just
let
me
know
and
then
I'll
take
care
of
the
logistics
on
on
that
and
I'm,
pretty
confident
that
it's
going
to
be
successful
in
popular
lab,
especially
with
the
variety
of
things
that
we've
been
talking
about,
and
we
we
do
have
another
set
of
equipment
from
that's
currently
in
Illinois
and
covid
delayed
moving
that
we
have
several
large,
the
several
large
dishes
for
the
interferometry
setup
and
and
a
lot
of
smaller
ones.
B
B
You
know
organizational
efforts,
it's
hard
to
to
manage
two
large
moves
to
the
same
side
at
once,
so
yeah,
just
as
soon
as
possible
would
be
great,
and
if
you
need
any
any
funding
or
any
help
at
all,
then
please
just
get
in
touch.
And
thank
you
it's
it's
awesome
to
have
this,
and
and
I
have
a
lot
of
optimism
that
this
particular
place
will
help
so
many
people
and
make
it
possible
for
for
people
to
participate
in
in
some
really
neat
citizen,
science
and
and
open
source
engineering.
C
C
The
remote
video
solution
for
the
Spectrum
analyzer
somehow
has
stopped
working
I
suspect
that
being
a
side
effect
of
a
Ubuntu
upgrade,
but
I
don't
really
know
that
I've
been
trying
different
solutions
trying
to
get
something
rigged
back
up.
So
people
can
look
at
the
Spectrum
analyzer
remotely,
mainly
me
from
across
the
house,
because
it's
easier
than
walking
across
to
the
remote
lab
to
see
what's
on
the
screen.
C
But
anybody
else
would
be
also
convenienced
by
being
able
to
get
the
video.
So
that's
an
ongoing
investigation
right
now
and
we
discovered
another
operating
system
version
issue
with
the
simulator.
We
tried
to
run
the
the
test
bench
for
one
of
the
sub
modules
that
we
use
with
the
encoder
and
it
didn't
work.
C
But
now
we've
got
to
be
up
at
least
version
21
in
order
to
run
the
ghdl
simulator
without
going
to
a
lot
of
trouble
to
build
it
from
Source,
since
whatever
problems
that
would
cause
so
I've
created
or
actually
upgraded,
another
VM
that
you've
probably
never
heard
of
called
nuts
in
Utz.
That's
the
name
of
a
one
of
karapi's
friends
and
in
the
Hello
Kitty
universe,
and
it's
upgraded
to
fully
to
22
LTS
and
it
can
run
a
simulator
just
fine.
C
We
ran
the
the
python
script
without
too
much
trouble
once
again,
I'll
look
for
requisites
lined
up,
and
this
seems
to
be
the
way
to
go
for
at
least
regression
testing
and
production
testing
of
HDL.
So
if
anybody
needs
a
version,
22
VM
on
the
remote
lab,
let
me
know
and
I'll
get
you
hooked
up
with
an
account
on
Nets
and
if
people
think
that
it's
time
to
give
up
on
version
18
for
the
main
VMS,
we
can
talk
about
upgrading
them
too.
But
I
want
to
be
pretty
cautious
about
that.
C
So
we
don't
break
things
that
people
are
relying
on
other
than
that
the
remote
Labs
or
remote
lab
here
is
is
working
and
nothing
too
much
new.
There
I've
been
working
with
Michelle
on
taking
a
a
tire
iron
to
the
to
the
Scruff
of
the
neck
of
the
the
problem
of
integrating
the
encoder,
which
works
on
Pluto
into
the
reference
design
on
the
zt706,
and
that
has
turned
out
to
be
more
of
a
big
deal
than
we
thought.
C
It's
not
a
standard
interface,
it's
designed
to
hook
up
directly
to
a
dma
interface,
but
it's
very
much
like
the
axi
interface,
so
we're
following
along
with
the
the
clues
we
found
in
other
axi
interface
code
and
are
just
about
ready
to
start
writing
some
detailed
equations
and
code
to
to
make
that
module
work,
and
hopefully
that
will
not
be
too
much
of
a
roadblock
for
too
much
longer.
It's
been
fun.
We've
learned
a
lot
and.
C
B
Yeah,
thank
you.
So
much.
That's
a
that's
a
really
good
summary.
The
the
particular
batch
of
of
code
that
we're
working
with
is
a
really
neat
set
of
Open
Source
fpga
cores
called
fpga
cores
from
Andre
suato
on
GitHub,
and
that
dbb
cores
is
a
sub
module
of
our
encoder,
which
is
in
the
transponder.
You
know
design.
B
So
what
we're
doing
is
picking
out
the
axi
bus
width,
converter
and
then
adding
the
case
for
upsizing,
which
is
was
not
in
there,
but
instead
of
making
a
general
case
for
for
this
we're
making
the
custom
interface.
So
that
will
go
a
long
way
to
solving
kind
of
the
tricky
problem
which
is
sort
of
introduced
because
of
the
the
type
of
of
interface
that
we
have.
The
jsd204b
is
expecting
a
much
wider
interface
than
then.
B
Perhaps
people
might
expect,
and
there
may
be
some
some
bite
reordering
and
things
like
that
that
need
to
go
on.
So
it
may
not
be
a
straight
over
interface,
but
it's
we
should
have
some
results,
if
not
today,
then
definitely
by
by
next
week.
Other
news
in
on
the
fpga
front,
there's
been
some
updates
to
the
to
the
encoder.
It
looks
like
on
some
updates
to
or
to
some
of
the
other
cores.
So
thank
you
very
much
to
Andre
for
continuing
to
work
on
this.
B
It's
just
fantastic,
there's
a
pretty
much
a
global
shortage
of
Hardware
Engineers
that
do
this
sort
of
work.
We
are
continually
grateful
for
everybody
that
takes
time
to
donate
their
work
to
us
for
free,
so
we
can
have
an
open
source
po
satellite
project.
Thank
you.
It
is
astounding
that
we
continue
to
have
such
wonderful
people
and
we
do
our
very
best
to
make
this
a
rewarding
fun
and
mutually
beneficial
sort
of
deal.
B
So,
if
you
know
of
somebody
that
might
want
to
either
learn
or
donate
their
expertise,
please
let
us
know,
because
we
have
lots
of
opportunities
and
we
have
plenty
more
projects
than
than
people
as
as
usual
for
for
research
institute
and
or
one
of
our
goals
is
education
and
professional
development.
So
just
let
us
know
if
you
any
of
this
sounds
intriguing.
Then
then
we
have
a
home
for
you
here,
even
if
it's
just
you
want
to
follow
and
support,
we
could
totally
use
the
the
support,
moral
and
otherwise.
B
So
we
do
have
one
of
our
regular
folks
is
out
for
the
next
month,
so
on
show
we're
looking
forward
to
him
coming
back,
but
he
won't
be
here
working
for
for
a
while
and
a
couple
of
other
people
have
been
on
vacation,
so
we're
looking
forward
to
them
coming
back
so
yeah.
That's
that
pretty
much
sums
it
up
any
questions
or
comments
before
we
close
the
the
stand-up
part
of
the
meeting.
B
Yeah
there
is
a
video,
so
the
office
hours
with
Jan
King
talking
about
pretty
much
the
high
level
open
source,
heo
project
high
for
a
or
high
flyer,
highly
elliptical
orbit
open
source
satellite
work.
We
cover
a
lot
of
different
things
in
the
office
hours.
The
next
office
hours
meeting
with
him
is
the
10th
of
November,
assuming
every
schedules
work
out
but
yeah.
B
If
you're
interested
in
hearing
more
about
how
the
the
satellite
project
is
going,
then
go
there
and
I'll
put
I'll
put
the
link
directly
to
it
in
the
description
for
this.
For
this
video
and
yeah.
If
you,
if
you
want
to
pitch
in
anywhere
from
propulsion,
to
attitude
control
to
to
what
we're
working
on
here,
which
is
the
communications
package
or
if
you
want
to
make
it
easy
for
payloads
to
be
included,
because
that's
that's
important,
then
then
we
need
you
and
I
think
we're
we're
lightest
on
mechanical
and
thermal.
B
We
don't
really
have
a
deep
bench
there,
because
our
our
background
and
origin
is
digital
Communications,
so
we
always
kind
of
assumed
that
there
would
be
we'd
be
providing
Communications
packages
to
other
organizations
that
had
existing
mechanical
and
thermal,
so
we're
lightest
there,
but
I
think
the
solution
might
be
simply
to
to
work
with
a
company
or
purchase
something
off
the
shelf,
because
there's
lots
of
options
here.
That's
a
little
less
satisfying
for
open
source
I
think
it'd
be
nice
to
design
it
from
scratch
and
machine
it
up
in
our
garage.
B
But
whatever
gets
us
there
with,
as
many
people
happy
and
fulfilled
is,
is
the
goal
but
yeah
there's
a
there's,
a
video
up
and
it's
it's
good
and
we'll
have
more
soon.
B
Yeah,
the
next
set
of
demos
that
we
have
scheduled
is
not
until
March
2023
really
will
be
a
big
part
of
ham.
Expo.
A
B
Kuso
today
ham
Expo
in
March
of
2023,
and
we
some
of
our
our
projects
like
versatoon
and
possibly
Ribbit,
but
but
it
looks
like
nobody
can
afford
to
take
the
time
off
from
their
day.
Job
will
be
at
hamcation,
so
we
we
anticipate
that
we'll
have
a
presence
of
hamcation
for
receiver
projects
for
terrestrial
work
and
whoever
else
wants
to
show.
B
But
in
terms
of
like
spacecraft,
stuff
and
the
the
transponder
for
space,
then
we're
then
we're
next.
Looking
at
public
demonstrations
in
March
of
2023
in
between
then
and
now,
there'll
be
several
articles
in
around
the
world.
I've
seen
the
draft
for
the
jamsat
journal
that
covers
our
project
and
it's
great,
it's
great
it's
in
Japanese,
so
you
know
plan
accordingly
and
we
have
the
Uplink
Ford
air
correction.
Article
appearing
in
qex
and
more
are
more
articles
will
be
submitted.
B
I
think
that's!
That's
a
good
bet
for
for
a
lot
of
the
work
that
we
do
we're
starting
to
look
at
IEEE
as
a
place
to
to
send
work,
but
the
the
copyright
situation
and
with
with
IEEE,
has
always
been
problematic
for
people
that
do
open
source
work.
You
know
the
paywalls
and
such
for
IEEE
are
pretty
harsh,
but
we're
getting
to
the
point
where
that's
the
place
where
we
should
start
thinking
about
about
publishing.
B
You
know
so.
That's
that's
the
Roundup
for
for
for
documenting
all
of
this
stuff
is
available
on
our
repositories.
We
now
have
40.
and
probably
more
coming
with
the
work
that
we're
looking
at
doing
with
propulsion,
all
right,
any
other
questions
or
comments
or
anything
I
missed.
B
Yeah,
thank
you
to
everyone
for
your
time
and
attention
and
I'll
be
we'll
be
working
all
week
and
see
you
on
slack
and
if
you're,
if
you're
interested
in
joining,
