If they use one antenna for both AIS and APRS...
(APRS was added as an afterthought, completed in six days, just a box, no
antenna, no battery, no power panels.)
If this is the case, AIS has thousands of ships all trying to work the
antenna automatically.
There are only a few hams trying to work APRS through the same antenna per
pass.
Without proper diplexing, how would this system not be blind to APRS ?
AIS is ~160 MHz for ship to shore connections.
Not sure what the sat connection freq would be for AIS.
Maybe it is time for AMSAT India and Exseedspace to inform us hams here ?

I worked many stations through RS12/13 and only used wire antennas
(dipoles, end-fed wires, etc.), so no directional antennas were used. I
seem to recall that those sats had higher than the usual 1/2 watt output as
well.

So, in researching AIS, the time slot phenomenon is telling..
AIS knows when to transmit, in order not to get bumping transmissions.
On an antenna where both AIS and APRS operates...(IF this the case, and we
do not at the moment have further information about the fourth stage setup),
AIS transmissions to and from the ships are time slotted. But what about the
random APRS transmissions ?
Maybe APRS telemetry and position beaconing from the sat could be time
slotted in with the AIS transmissions from the sat.
But what about APRS message uploads from hams ?
Am I overthinking this, or are there indeed separate antennas for AIS and
APRS on this rocket fourth stage ?

Full quieting into CenCal, but VERY low deviation. An earlier pass had
normal deviation.
Something changed on the ISS side.

It's too bad we will be in a low sunspot situation for the next few years.
But who knows what can happen.
You can read about G3IOR's experiences with OTH propagation RS-12 mode K DX
operation
where he was able to work a ZL station, in his article in the Jul/Aug 1993
issue of the AMSAT Journal
titled "Using RS-12 Mode "K" Anomalous Propagation".
I think the higher sunspots played a role with this.?
There's also his audio interview about this topic in 2015
at:https://criticaldistance.blogspot.com/2015/04/
it's almost at the end of the Radio Luxembourg audio at the top of the page.

Hi Joe,
This makes me sad. Not because of the audio issue itself or the
frustration of those who are wanting to copy the pictures from the Space
Station, but because of what the "Bad timing" comment represents. Has
Ham Radio gotten to the point where it's such a chore for the crew that
they can't take time from their day off to play with the radio? Has the
use of the ham station become so industrialized that it is nothing more
than another scheduled experiment package that they have to tend to?
Was it that long ago that the crew had to wait for a spare moment just
to use the radio? When did Ham Radio cease to be a fun hobby and turn
into a job?
I suppose it was inevitable. With ARISS, for example, the logistics and
the significant expense of coordinating and executing a school contact
make it something that needs to be depended on. I get that. Even the
various celebration events (NOTA, Cosmonaut’s Day, et al) are at least
theoretically widely publicized, so any failure would reflect poorly on
the organization sponsoring it. Nobody has any tolerance for risk these
days.
I started this thread with an observation, not a complaint. I hope it
has been taken as such. But the interest and participation in the
thread tells me that there is still a lot of interest in following (in
the traditional sense, not that of social media), and more importantly,
participating in the space program. This isn't just for show. The
armchair quarterbacks here on the ground have a ball in their hands, and
want to play.
Perhaps I'm reading too much into that statement. I hope I am. I also
get that ham radio isn't for everyone. But it makes me sad that the
spark for using ham radio has apparently been curated out of the ISS
crew and lost in space. The last pass (just setting as I type this)
heard nothing heard from the Station. Apparently better to just turn it
off than to have to deal with it.
How do we get the spark back?

Years ago, I used a cross dipole for ten with a screen under it. It had a
bowl shaped pattern and worked pretty well. For fifteen used a "J pole made
of twin lead from a tree. But as one poster noted when the bands were open
you didn't need much.

I used a 2 element HF yagi for uplink and downlink (mostly because that's
what was on-hand). I aimed the beam in a general North-South orientation but
as I recall it didn't matter much which way it was pointed. Geeeze ... I was
a youngster back then!

Sharing the 2m antenna...
(APRS and AIS)
IF this is the case, then...
Hope suitable design and testing went on before the launch.
Even if two separate antennas are used, they might heavily interfere with
each other on the same band.
And if hundreds of AIS ship customers are beaconing through the sat, then
the APRS system might be deafened by same band, close frequency interference.
Maybe the reason why lots of RF power is required to work this sat on APRS.
Repeater builders know this...
http://www.repeater-builder.com/projects/2m-dup/dupfig13.jpg
http://www.repeater-builder.com/projects/2m-duplexer.html
One other solution might be to alternate the systems on and off.
Thus no interference takes place system to system.
If this is the case, then we simply do not know the APRS "on" schedule.
It could be off over NA today and on again over NA tomorrow.
Where can we find better guidance ?

Only the astronauts who are licensed hams are allowed to operate the
equipment...same as here on earth. Currently, I believe there are two
licensed hams aboard.
The astronauts basically work 12 hour days, divided into 15 minute time
slots. I believe it is 0700 - 1900 UTC. They are sleeping part of the
time we are trying to get SSTV images.
On weekends, they try to catch up and have some time to talk to their
family and friends back here on earth. That would be my priority as well.
The number of experiments they run are too many to count, but you can find
a list here, if you are interested:
https://www.nasa
.gov/mission_pages/station/research/experiments/experiments_by_expedition.html
#5354
They also perform maintenance, EVAs (spacewalks), give each other haircuts,
clean the bathroom, etc.
The SSTV radio is located in the Russian segment of the ISS, and they are
on holiday.
The priority for the licensed astronauts' time with the ham radio equipment
is the school contacts that they facilitate worldwide (not just US), and
there are many. We are thankful that they work those in because it is the
most exciting way to introduce young people to ham radio, not to mention
STEM activities.
Having said all of that, I, too, like to copy the SSTV transmissions and
use the APRS system. I understand the frustration, but it has nothing to
do with NASA or astronauts losing interest in ham radio activities. During
a recent mission, astronaut Serena Aunon-Chancelor made several voice
contacts with hams on the ground during her spare time (and enjoyed doing
it).
The equipment on board the ISS is aging and becoming less reliable.
Replacements are in the works, but the effort and expense to get them
flight-ready is huge. If you would like to help, get out your checkbook
and send ARISS a gift. The ARISS folks spend an unbelievable amount of
their own personal time trying to keep the rest of us happy. They are
volunteers who have a driving desire to keep the amateur radio community in
the space program. They work very hard at keeping everything moving
forward.
None of this was meant to be critical, so please don't take it that way. I
understand and sometimes share the frustration.
There are other ways to participate in the space game. AMSAT has given us
MANY opportunities that don't rely on an astronaut's schedule.
Space is hard, which is what makes it rewarding.
I, for one, am thankful for the opportunites we have...even when they are
not perfect.
