2023 Hamvention Wrap-Up

The 2023 Dayton Hamvention is in the books! It was a great weekend in
Xenia, OH and at the various other events in the surrounding area. The
AMSAT booth and satellite demo area saw continuous traffic and attendees
had an excellent time at the informal AMSAT Dinner at Tickets on Thursday
evening and the TAPR/AMSAT Banquet on Friday evening.

The AMSAT forum from Saturday afternoon can be viewed at
https://www.youtube.com/watch?v�YTVTzJlXk&t680s (the ARISS forum
precedes the AMSAT forum, so you can back up the live stream to view that)

The video presented at the AMSAT forum featuring AMSAT engineers can be
viewed at https://www.youtube.com/watch?v�zTtJZPfL8

Grace Papay, KE8RJU, gave a talk at the Youth Forum on "Amateur Radio
Satellites Both Near and Far" and her presentation can be viewed at
https://www.youtube.com/watch?v�-jsYYHY8w&t

We hope everyone enjoyed Hamvention this year and hope to see everyone in
Xenia next May!

AMSAT Orbital Elements Manager Retires

It is time for me to retire from the position of AMSAT-NA Orbital Elements
Manager.

I have held this position since October 8, 1993, when I inherited it from
Dick Campbell, WR5RW (formally N3FKV). I also inherited a BASIC sorting
program from Dick which has faithfully produced the AMSAT TLE format each
week for almost 30 years. Today I have to use an emulator, but it
consistently produces the format we (and our computer tracking programs)
expect to see.

But, have no fear, Joe Fitzgerald, KM1P has been developing a
software-based system that pulls the TLE data directly from the internet
(Space-Track, 18SPCS), formats it, and sends it out to the amateur radio
community. Joe has been testing it for over a month now and it is ready to
go!

It has been a privilege to serve AMSAT as Orbital Elements Manager and I
will miss the Thursday night routine of sending out the AMSAT TLE. But to
those who have helped me along the way … thanks. Special thanks to
Keith
Pugh (W5IU Silent key), Dick Campbell (WR5RW), Nico Janssen (PA0DLO), and
also to Joe Fitzgerald (KM1P) for stepping up to the job.

New SO-50 Distance Record

A new distance record has been claimed on SO-50. During a SOTA activation
of Pine Mountain in the Upper Peninsula of Michigan on May 24, 2023 at
13:16 UTC, Joe Werth, KE9AJ, worked George Mamjis, MI0ILE, in Northern
Ireland. KE9AJ's location was EN55wu90gp and MI0ILE's location was
IO64wn80. The distance between the two locations is 5,584 km. The previous
record on this satellite was 5,523 km - set by F4DXV and N1AIA on October
24, 2018.

Changes to AMSAT-NA TLE Distribution for May 25, 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/

This week there are no additions or deletions to the weekly AMSAT-NA TLE
distribution.

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.
