PSAT2 is doing great!
PSK31 and SSTV transponder have been on since launch.
SSTV downlinks are looking good.
See Gallery: http://www.urel.feec.vutbr.cz/esl/psat2/sstv/
Still waiting for first report of user PSK31 contacts.
But I have not said much about the VHF modes? because we have had
difficulty commanding. This is because the PSAT2 VHF uplink uses an
inexpensive narrowband XCVR module which is intolerant of overdeviated
signals, exactly what you get with +/- 3 kHz of Doppler.
ANYWAY, we can now consistently command if we set the Kenwood to narrowband
NFM and do it right in the middle of the pass. Plus, we can extend that a
bit (1.25 KHz after center) by then changing the radio step size to 6.25
Khz where the channel raster ups the channel by 1.25 KHz).
So, we now have command again! You may have seen that we have turned on
Sun vector S#... telemetry and can easily see by plotting the 1 minute xyz
xyz xyz vector triplets that it is smoothly tumbling at about 1.3 RPM for
nice battery charging and good thermal management.
The downlink is live on FINDU:
http://www.findu.com/cgi-bin/raw.cgi?call=psat2-1&time=1
Background:
This last 6 days of crisis was complicated by the fact that I am operating
in a temporary dungeon while the building is being renovated and all my 27
years of lab stuff is in 200 boxes surrounding me. I installed a temporary
ground station on the top floor and modest antennas and a TV rotator and
the contractor let me drill a hole through the wall that they can seal up
later. But the big problem is the 8 flights of stairs from my PC and
internet connectivity in the dungeon up to the radio 6 times a day for
passes with only a few hours sleep and all kinds of what-if-dead-ends. And
with passes from 10 PM to 2 AM.
But we are back in the saddle again!
And this good news reprieve is only an hour old, so it will take a while to
decide what we want to do next. In any case, the Brno University PSK31 and
SSTV transponder has all the power for now, so enjoy.
Uplink USB on 29.4815 and downlink on 435.350 +/- Doppler. The transponder
only comes up if there is a user in the uplink with PSK31.

Hello Bob,
I've taken a picture of the waterfall from the raw IQ file so the
frequency is not correct, but here it is:
http://bx2abt.com/main/data/_uploaded/image/20190701-1257_435360-PSAT2.png
The PSK31 signal is around 380 Hz, but still can't decode it. Anybody
who wants to try: here is the audio file.
http://bx2abt.com/main/data/_uploaded/media/20190701-1257_435360-PSAT2.mp3
I don't have a digital setup for HF, so can't do PSK31. It also means a
dual setup for audio/PTT on one PC. I doubt if I have enough USB ports
for that, hi hi.
Later....

Content-Type: text/plain; charset="us-ascii"
Hello folks:
I just upgraded my tired FT-847 for a new IC-9700. FM birds are not a
problem but I'm wondering if someone has a good method of finding your
signal on the linear birds while using SATPC-32 revision 12.8d. The only way
I can vary the TX frequency is under the CAT Tuning menu Upl Calib field. It
seems to work but it's a bit clunky and not very quick. If I try to change
the transmit frequency on the radio it only gives me a few seconds then
reverts back to what is on the main screen of the PC. If I try changing the
receive frequency, the transmit frequency changes as well. Probably new
radio operator error but I would appreciate any suggestions.
Thanks//Dave WB9YIG

Glad to hear all the positive news, Bob! Thanks for keeping everyone
informed.
Regarding TLE, how sure are we that PSAT-2 is Object 44357 as indicated in:
https://www.celestrak.com/NORAD/elements/tle-new.txt
... at the suggestion of JA0CAW, a very accomplished amateur in Japan, on
tonight's passes I attempted to determine whether PSAT-2's downlinks on
145.825 & 435.350 might be stronger by tracking Object 44355 (2019-036S).
And, while you can't reach any conclusion from only two passes (nor at such
low elevations), by eye & ear the downlinks seemed stronger when tracking
44355.
Of course, any number of factors could skew my result and tonight's
observation was subjective at best. But I wanted to put this on the
mailing list in case anyone else would like to do any similar tests.
FYI, just like last night I saw short snippets of PSK31 streams around the
280Hz & 375Hz marks but unfortunately still no sign of my 10m PSK31
uplink. I also got a few seconds of clear SSTV audio again tonight. The
70cm downlink is looking great! Just need a little more elevation for my
modest setup and location (Virginia).
Thanks!

Message-ID: <9187EEF7FA3D4FC183BE625120E1CEE0@???>
Content-Type: text/plain; charset="iso-8859-1"
An International Space Station school contact has been planned with
participants at Santa Barbara Public Library, Santa Barbara, CA on 03 July.
The event is scheduled to begin at approximately 17:54 UTC. The duration of
the contact is approximately 9 minutes and 30 seconds. The contact will be
direct between NA1SS and K6TZ. The contact should be audible over the state
of California and adjacent areas. Interested parties are invited to listen
in on the 145.80 MHz downlink. The contact is expected to be conducted in
English.
The Santa Barbara Public Library's mission is to provide information
services, reading materials, and educational resources to the greater Santa
Barbara community. The Library provides STEM programs and a wide range of
maker programs year round. The Library enriches lives by creating equitable
opportunities for learning both at our libraries and outside our walls in
locations throughout the community. All of the Library's services are free
of charge. Every summer, the Santa Barbara Public Library holds a Summer
Reading and Learning Program for readers of all ages, which especially
targets school age children to help prevent summer learning loss. This year,
the theme of the program space exploration, and includes a series of STEAM
programs related to astronomy, physics, radio communication, and other space
related topics, in preparation for an ARISS (Amateur Radio International
Space Station) contact taking place the first week of July. STEAM programs
this summer include the following
:
Cook up a Comet - What are comets, and how do they form? Kids can learn
about these astrological phenomenon and create their own.
What is Amateur Radio? - Learn more about how our radio Space Station
contact works by connecting with Santa Barbara Amateur Radio Club (SBARC),
the group that is making contact with the ISS possible.
Little Bits ISS and Mars Rover - Learn about radio communication on the
International Space Station or satellite communication with the Mars Rover
by building your own model with Little Bits circuits.
Robotics Camp - Build and code your own space rover using Hummingbird
Robotics in this week long camp.
Summer Space Camp - This will be a week-long camp where we'll focus on
engineering, space, aeronautics, and the space station. Activities will
include Wonderbots retrieving space samples, building and launching rockets,
and astronaut boot camp.
Participants will ask as many of the following questions as time allows:
1. What's the most interesting thing that you have seen while you were
on the space station?
2. Are there any planets that you've found that we could live on?
3. How do you take a shower?
4. Are pets and/or animals allowed on the ISS?
5. How do you survive and eat on the space station?
6. What does it feel like to be in space or the ISS?
7. What is it like to be weightless and float in space?
8. Has the ISS been hit by space debris?
9. What does Earth look like from very far up?
10. What do you do in your life on Earth that you cannot do in space?
11. At your current orbit, do you have sunrise and sunset and how many
hours of daylight do you have?
12. If the ISS was rebuilt what would you do differently and should
another be built?
13. Living in space or anywhere else other than on earth is very
dangerous. Why not just send robots?
14. Can you get sick while in space?
15. Do radio waves travel slower in space?
16. How do Astronauts use the restroom at the space station or when
traveling to the space station?
17. How do you repair the space station?
18. Why do you eat Jello on Mondays?
19. What experiments do you do? Are you doing any research in space
that was your idea?
20. What do you do with your waste? Is there compost?
21. How many "pounds of thrust" are required to launch the rocket that
boosts the space station into space and what does it feel like?
22. How many years does it take and what tests do you have to pass to
become an astronaut?
23. Do you see space vehicles from other countries during your
observations?
24. What was it like when you found out you actually get to go to the
space station?

About ARISS
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.

Hi Dave,
On my 9700 I have SATPC32 V+ (VFO Mode On) selected which allows me to tune
up and down the band with the radio's VFO knob and SATPC32 freq display
follows that and changes accordingly. I also look for my CW signal on the
waterfall with CW+ (CW MODE ON) and use the up/down Cal to get synced up
then it's a mouse click to CW- to get back to SSB. I'm a newbie but that's
what I found so far works for me.

Dave,
the "Uplink Calibration" feature has been unchanged for at least 15
years, hi. You are right, the calibration has to be done via the "Upl.
Calibr." controls in menu "CAT" (the FT-847 is the only radio that
allows uplink calibration additionally by its Sub VFO knob). The program
does not cancel the uplink corrections you made "after a few seonds" but
continues with the changes until the program is shut down. Of course, it
continues with Doppler correction but on the base of the new uplink
frequeny.
Track an SSB sat - say FO-29 ' . Then correct the uplink frequency in
menu CAT until you hear your own signal with the best audio pitch. Then
click "Change/Store Data file" and then "Uplink Calibration". That will
save the changes in Doppler.SQF (watch the frequency list in menu CAT to
see the modification). At the next program start you should immediately
hear your signal with the right audio or very close to it. Little
remaining deviations (100 - 300) Hz, due to temperature changes etc.)
can then be corrected without new storage by the +/- keys of the
keyboard (that works only if the main window has the "focus" = dark
header line).
I tested the IC-9700 during? a few passes of FO-29. The audio of my
signal remained constant during the whole passes without any corrections.

I run SATPC32 on a Win10 tablet portable with my ICOM 820H.
Make sure your clock and keps are current (sync immediately before the pass)
On FO-29, you shouldn't have to move the TX offset more than +/- 1Khz to
find yourself.
On my current tablet, it was +800Hz, on a previous laptop, -600. You're
adjusting for PC clock tolerance,
temperature, location accuracy, and VFO accuracy.
Once you do, you can set that as a permanent offset so you don't have to do
that again:

AO-7 is much tougher, as some of the published doppler.sqf files are 3 to
4Khz off from reality
(your mileage may vary)
The XW's seem to be spot on, with little or no adjustment.

Hi folks,
I will be operating with the K2J callsign from FM05 on the 2019-07-02
- 2230 UTC - SO-50 pass.
This is a nice pass over the center of North America.
K2J is the North Carolina callsign for the 13 Colonies Special Event:
