I may have one of these 23 cm modules available for the 9100. Anyone
looking for one?

Hastily listened to the 0044utc 27th June pass over VK to see if I could
hear any of the new birds.
Just grabbed TLE set 36R, no logic to that, just that they should be still
grouped.
Had my Funcube Dongle set to listen 437.465 to 437.555.
Was low elevation pass but certainly activity on waterfall.
Copied 8 frames from CP-9 and noted a marginal signal adjacent so tuned to
it.
Eventually two decodes from Armadillo.
There's a star. There's another one. Star. Star star star. Star.
Don't like space. Don't like space.
Next pass is higher elevation, so maybe better results.
No guarantees in this game.

Congrats Ronald!
You are the first to succesfully receive SSTV pictures from our camera,
the first one is from the pictures stored in processor before flight,
the second is taken after the power up of the camera in space, there
should be 7 more stored, of course, not all would have Earth in field of
view. Later after evaluation it can be commanded to have pictures on demand.

PSAT2 is coming to the Northern hemisphere!
After reviewing the orbit, it is somewhat time synchronous, meaning each
orbit time (at mid northern latitudes) is just 5 minutes later each night.
But then a NEW earlier orbit appears 90 minutes earlier every other day.
So, by the 4th of july, one week from now, PSAT2 first pass will be as
early as 4 PM local time... (in the Northern Hemisphere mid latitudes)
And the Apogee moves rapidly, In just two weeks, Apogee will be over the
northern hemisphere giving higher latitudes much better access. At launch
it was the middle of the night and perigee was in the Northern hemisphere
making it only visible for lower latitudes.
So things will improve for Northern Hemisphere .... (and then two weeks
get worse, etc)...
24 Hour telemetry plots (links to FINDU.COM) are now available on the
http://aprs.org/psat2.html page.

That's great, Roland! Thanks for the updates.
The elevation is still too low for me to receive any of the 70cm downlink,
but I have been hearing some of the 2m APRS on 145.825.
It was great news to see the post from Bob regarding the orbit slowly moving
north.
If you can, please monitor the 70cm downlink for any sign of PSK31 - since
Bob announced that the PSK31 transponder was active, I have been
transmitting on the 10m uplink on the chance that the satellite hears me
even at such low elevations.

Scott,
Just curious --
Does the 10m uplink have any bounce/skip off the atmosphere? Seems like you
should be able to "reach" around beyond line of sight at that frequency.
Right?

The ionosphere can bend your uplink down so that it does NOT hit PSAT2 when
it is low on the horizon. On the other hand, at the horizon, it might also
at times bend just enough to extend the footprint. But you wont hear the
UHF downlink to know...
So I suspect, the ionosphere will be more in the way than not.
Just a wild guess. With the same PSK31 transponder having been on 100% for
over 2 years with the original PSAT (NO84), there has not been enough users
to really know what happens. It also downlinks on the same frequency. (but
uplinks in the normal ten meter PSK band at 28.121) so if there are ANY
users at all on 10m then they will bring up the transponder.
But on PSAT2, the IARU decided all uplinks must be in the satellite band and
we had to m ove the uplink to the exclusive 29.481 frequency.

I can only speak to how it?s been working with the original PSAT (NO-84),
which is VERY good.
With only a long wire HF antenna
(http://myantennas.com/wp/product/efhw-8010/) suspended around 4 meters off
the ground, I have often seen my PSK31 TX stream coming back down on the
70cm FM downlink at as little as 10 deg. elevation.
However, this time of year with leaves on the trees, it needs to be closer
to 20 deg., but that's still pretty good.
So yes, I'm hopeful that I can be heard w/ a 10m uplink even while PSAT-2 is
still in that southern phase of its orbital pattern. If PSAT-2 works
anywhere near as good as PSAT does, it's going to be really hard to resist
putting up a dedicated 10m antenna such as the PAR HF-28!

That last pix was from the top of my desk back in the summer of 2017!!
The hams at BRNO University delivered the PSK31/SSTV module for PSAT2
on-time and on-budget (free to us). They worked over the holidays to meet
a very short deadline and delivered in February 2017 for a March
Integration.
Then 2+ years of launcher and FCC delays and it finally got launched now!
I guess whenever I powered it up, it must have been taking pictures.
Im sure it was frustrating for them to see all the launch delays, but each
was only a few months and so there was no time (and risk was too high) to
send it back to the Czech Republic for them to do any more tweaks...
(Like I got to do on PSAT2 firmware for 2 years!)
