Hi, all.
What applications are being used to decode BPSK 1k2 and BPSK 9k6?
I've been searching but have not turned up anything.
Thanks!

It?s my experience with my arduino based tracker that the TLEs age rapidly
and must be refreshed on game day.
I attributed this to the single precision math although it could be due to
some more fundamental misunderstanding on my part.
Now that there are no more shuttle re-supply flights even ISS reboosts are
fairly infrequent.
I am using the most excellent qrpTracker library (Bruce Robertson VE9QRP)
which is in turn derived from PLAN13 (James Miller G3RUH).

Uli,
You change frequencies on all of the satellites, for the FM satellites it
is on the 70cm band. On SO-50 you adjust the receiver, AO-85, 91 & 92 the
transmitter is adjusted.
It took me a while to get used to changing the transmitter during a pass,
since it is not as noticeable as it is on the receiver; more so since I
listen at more than I transmit.
Not sure if you caught this on another thread on the BB:

Hello,
I've set on memories for Yaesu FT-897 and Baofeng UV-5R for FM Sats:
SATID Downlin Up-link STone
SO50E 436.802 145.847 77.4 (Corrected STone)
SO501 436.802 145.847 67.0
SO502 436.794 145.850 67.0
SO503 436.786 145.853 67.0
AO851 145.980 435.180 67.0
AO852 145.977 435.172 67.0
AO853 145.974 435.164 67.0
AO911 145.964 435.242 67.0
AO912 145.961 435.250 67.0
AO913 145.858 435.258 67.0
AO921 145.883 435.342 67.0
AO922 145.880 435.350 67.0
AO923 145.877 435.358 67.0
Using http://amsat.org.ar/pass to see when the satellite will show, using
xxx1 for AOS, xxx2 for TCA and xxx3 for LOS.
So far success on contacts, hope is useful.

>
> Jeri Ellsworth, AI6TK, will present on her innovative ideas and
> adventures in Amateur Radio. Jeri is an American entrepreneur, self-
> taught engineer, and an autodidact computer chip designer and
> inventor.
>
> She gained notoriety in 2004 for creating a complete Commodore 64
> system on a chip housed within a joystick, called C64 Direct-to-TV.
> That ?computer in a joystick? could run 30 video games from the early
> 1980?s, and at peak, sold over 70,000 units in a single day via the
> QVC shopping channel.
>
> Ellsworth co-founded CastAR (formerly Technical Illusions) in 2013
> and stayed with the company until its closure on June 26, 2017. In
> 2016 been flagged as acceptable.
>
> 2. Do not use attachments. (Pictures and other files should be
> included by a link.) They will be blocked to the list, and if the
> total size of the message plus attachments exceeds 50 kB, the mail
> will be held.
>
> 3. Send it to AMSAT-BB and a few other addresses at most. If you
> must send to a large distribution list, send to them, and another
> copy to AMSAT-BB. (A trick which seems to work well is to place most
> of the addresses in the BCC rather than CC line.)
>
> 4. Consider also posting to the AMSAT Twitter and Facebook accounts.
> There is overlap in membership, though at present it is far from 100%.
>
> 5. Do not send large commercial press releases, or things which look
> like them. They will be caught by heuristic spam filters. A simple
> posting of an event or activity will normally go through. Note that
> there are existing exemptions for official channels such as ANS,
> ARISS, other AMSAT organizations, etc.
>
> 6. All new accounts are automatically flagged for moderation. This
> flag will normally be cleared on the first or second posting, but do
> allow for and expect an initial delay if you establish a dedicated
> account for your satellite organization.
>
> 7. Remember that this is a text-only list. Posting using HTML
> formatting will have unpredictable results, and may trigger the 50 kB
> hold for what appears to be a short message.

> ISS Orbit Reboost Saturday May 12
>
> The International Space Station was scheduled to raise its orbit this
> weekend (Saturday, May 12) to prepare for the departure of three
> Expedition 55 crew members and the arrival of a new Russian cargo
> craft. The docked Russian Progress 69 resupply ship will fire its
> engines Saturday at 6:07 p.m. EDT for two minutes and 52 seconds
> slightly boosting the orbital lab?s altitude.
>
> This orbital reboost sets up the proper phasing trajectory
> for the Soyuz MS-07 spacecraft when it undocks June 3. The
> Soyuz will carry Commander Anton Shkaplerov and Flight
> Engineers Scott Tingle and Norishige Kanai back to Earth
> after six-and-a-half month mission in space. The reboost
> will also enable a two-orbit launch to docking opportunity
> for Russia?s next resupply ship the Progress 70 in July.
>
> [Ed note: Stations who have not refreshed their Keplerian
> Elements will discover that the ISS is arriving slightly later
> than predicted.]

> Three CubeSats with Amateur Radio Payloads Deployed from ISS
>
> The Japan Aerospace Exploration Agency (JAXA) has announced that
> three CubeSats carrying Amateur Radio payloads, including one with a
> V/U linear transponder, were deployed from the International Space
> Station (ISS) on May 11 at around 1030 UTC.
>
> Irazu (Costa Rica) and 1KUNS-PF (Kenya) carry beacon/telemetry in
> the 70-centimeter Amateur Radio band, while UBAKUSAT (Turkey) carries
> an Amateur Radio linear transponder for SSB and CW, in addition to CW
> and telemetry beacons. Irazu is a 1U CubeSat developed by students at
> the Costa Rica Institute of Technology, with a telemetry beacon at
> 436.500 MHz. 1KUNS-PF is a 3U CubeSat developed by students at the
> University of Nairobi, with a telemetry beacon (9.6 kbps) at 437.300
> MHz.
>
> UBAKUSAT, a 3U CubeSat developed by students at the Istanbul
> Technical University, has a CW beacon at 437.225 MHz, and a telemetry
> beacon at 437.325 MHz. The linear transponder downlink is 435.200 -
> 435.250 MHz; the uplink is 145.940 - 145.990 MHz.

> allows:
>
> 1. What are the challenges that astronauts face while working inside
> the international space station? How are these issues addressed?
> 2. What can you give as an advice or words of inspiration to young
> aspiring Filipinos dreaming of becoming involved in NASA's (or
> International) space programs?
> 3. The Philippines is one of the most disaster-prone (typhoon,
> earthquakes, and volcanic eruptions) countries in the world. What
> researches does the ISS have to help these countries (or the
> Philippines, in particular) minimize risks related to such
> disasters?
> 4. Which of the recent breakthroughs/discoveries in your research in
> the ISS is your team's favorite and why? 5. Given the latest
> discoveries/experiments your team has done in the ISS, which
> field in science and technology do you think has the most
> promising advancement in the upcoming years?
> 6. How can the youth have a more active participation in space
> programs? (Skills training, seminars, etc.)
> 7. How long does it take to get use to the weightlessness in space?
> 8. What did you do before you became an astronaut?
> 9. Compared to Earth-based monitoring programs, how does the ISS
> facilities and equipment help in monitoring environmental
> disasters?
> 10. What can the Philippines do if it wants to participate in
> international space programs?

> + ARISS Story Line Featured in Book
>
> Emily Calandrelli KD8PKR recently released her third short novel for
> kids, "Take Me to Your Leader". In it, her main character, Ada Lace
> uses amateur radio around her hometown. She also uses radio to
> contact an astronaut on the ISS. I believe it is Sandy Magnus in her
> story. Even though the contact does not follow the ARISS protocol,
> she talks about the ARISS program in one of the appendices at the
> back of the book.
>
> If you (or your schools) are ever looking for a good short book to
> explain a little about radio contacts, this would be a good choice.
