AO-95 QRT
After a lingering illness of the battery, AO-95 passed away peacefully on
December 23rd. While a miraculous return is always possible, it is not
expected.
AO-95, known prior to launch as Fox-1Cliff to commemorate amateur satellite
pioneer Cliff Buttschardt, K7RR, who became a silent key in 2007, launched
on December 3, 2018 on a SpaceX Falcon 9 from Vandenburg Air Force Base.
Shortly after deployment, the AMSAT Engineering team received nominal
telemetry data from the satellite, but upon the first attempts at
commanding, it was discovered that the receiver had failed for unknown
reasons. Still, the satellite provided an easy to receive beacon and
telemetry data for over four years before the NiCd batteries failed.

New Satellite Distance Records
A number of new distance records via satellite have been claimed over the
past couple of months. First is the massively popular new MEO satellite
IO-117. Burt DeMarcq, FG8OJ, worked Shigenori Nasu, JH8FIH, on November 25,
2022 at 08:22 UTC. The distance between FG8OJ in FK96hg63 in Guadeloupe and
JH8FIH in QN14qi16 in Japan is 12,823 km.
Note that for future claims of IO-117, only live QSOs may be counted and
not those completed over multiple orbits using the satellite's delayed
messaging capabilities.
A new distance record was also claimed via the QO-100 geostationary
satellite. PT9AL in GG27os in Brazil worked XW4KV in Laos OK27jj on
December 10, 2022 at 14:41 UTC. The distance between the two stations is
17,834 km, eclipsing the previous record held by PR8KW and YC5YC of 17,378
km.
Finally, FO-118, launched in December is a LEO satellite carrying three
transponders. Familiar faces for the AMSAT Satellite Distance Records have
claimed the initial record on all three transponders - the V/u FM
transponder, the V/u linear transponder, and the H/u linear transponder (15
meter uplink). F4DXV and VE1CWJ completed transatlantic QSOs on all three
transponders. On January 6, 2023 at 04:15 UTC, they completed a QSO via the
V/u FM transponder and then switched over to the V/u linear transponder to
complete a QSO there one minute later. VE1CWJ was in FN85do83sg and F4DXV
was in JN04js20pr. They completed the sweep of all three transponders on
January 30, 2023, when they completed a QSO via the H/u linear transponder
at 17:16 UTC. VE1CWJ was in the same location while F4DXV was in JN04it22nt
for this QSO, for a distance of 4,908 km.
Anyone who wants to claim a distance record via an amateur satellite should
check the current list at https://www.amsat.org/satellite-distance-records/
and email n8hm at arrl.net if they complete a new record distance. Audio
and/or video of the QSO is encouraged but not required.

Changes to AMSAT-NA TLE Distribution for February 2, 2023
Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. TLE bulletin
files are updated Thursday evenings around 2300 UTC, or more frequently if
new high interest satellites are launched. More information may be found at
https://www.amsat.org/keplerian-elements-resources/
AMSAT IT, in conjunction with the New England Sci-Tech STEM Education
Center assembled a tiger team of software experts from the Olin College of
Engineering, Boston Latin School and the Wilson Middle School to
investigate the recent disappearance of AO-7 from
www.amsat.org/tle/current/dailytle.txt and the legacy naasbare.txt files.
The team determined that AMSAT's processing is not robust in the face of
minor format differences in the source data received from the USSF's 18th
Space Defense Squadron. Specifically, the TLE data provided does not
always include the leading zero in AO-7's object number "07530". The
official report from the team's leader : "My grandma would say that AMSAT's
software is just a little too persnickety". A member of the tiger team
agreed to adjust the update script to account for the vagaries of the 18th
SDS data. A production quality fix is expected by March 1st, meanwhile
manual monitoring and updates will keep AO-7 in the files.
There were no changes to the February 2, 2023 distribution.

Special thanks to our ARISS telebridge ground stations. Approximately 38%
of the ARISS school contacts are handled by the ARISS telebridge stations.
Thanks to following stations: AB1OC, IK1SLD, K6DUE, NA7V, ON4ISS, VK4ISS,
VK4KHZ, VK5ZAI, VK6MJ, and ZS6JON.
The crossband repeater continues to be active. If any crewmember is so
inclined, all they have to do is pick up the microphone, raise the volume
up, and talk on the crossband repeater. So give a listen, you just never
know.
Comments on making general contacts
I have been seeing a lot of traffic on Facebook and I suspect on other
social media sites with people asking why they are not hearing the crew
make general contacts. First off the crew is very busy on the ISS and they
simply may not have the time to just pick up the microphone and talk.
Also, one needs to be aware of their normal daily schedule. I have listed
below the constraints that we at ARISS have to follow in order to schedule
the school contacts. Hopefully this will help you better schedule your
opportunities.
Typical daily schedule
Wakeup to Workday start.5 hours
Workday start to Workday end hours
Workday end to Sleep hours
Sleep to wakeup.5 hours
The crew's usual waking period is 0730 - 1930 UTC. The most common times to
find a crew member making casual periods are about one hour after waking
and before sleeping, when they have personal time. They're usually free
most of the weekend, as well.
SSTV events are not that often. So please check out https://www.ariss.org/
for the latest information or watch for the ARISS announcements.
And dont forget that the packet system is active.
As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol.

Satellite Shorts From All Over
+ The FO-99 operation schedule for February is available at
https://www.jamsat.or.jp/?p 79 (Thanks to JAMSAT for this information)
+ A volunteer is being sought to take over the Gridmaster Heat Map on
Twitter. Paul Overn, KE0PBR, has announced his intent to “retire
from the
project that he has moderated there for the past three years. Paul has
assisted many grid chasers by relaying information about rovers, and
keeping tabs of which grids are in greatest need. Unless someone steps
forward, Gridmaster Heat Map will disappear next month. Thanks to Paul for
your valuable contribution to satellite operations! (ANS thanks Paul Overn,
KE0PBR, for this information)
+ A while ago, perhaps almost two years ago, I modified the LVBTracker
firmware in my Fox Delta ST2-USB so that it would allow for more
calibration points than just the min and max for azimuth. I had added a
remote-control option to an old Yaesu G-450XL, but the output voltage was
very non-linear, which led to terrible aiming of the antennas. With the
mods I made to the firmware it now allows me to calibrate the controller at
0, 90, 180, 270, and 360 degrees and aiming is now rather accurate. I wrote
about it here:
https://thehamlab.com/2023/02/02/fox-delta-st2-lvbtracker-calibration-mods/
If you feel this could be useful for you, the source code for the project
can be found on GitHub:

+ SuitSat-1 (AMSAT-OSCAR 54) deployed from the ISS 17 years ago February
3rd. It played voice messages in languages recorded by the ARISS partners
and students from around the globe. It also sent telemetry data. It was
lost 15 days later. SuitSat came back to life in a 2021 short horror film!
