2026 AMSAT Field Day Next Weekend!
ItrCOs that time of year again; summer and Field Day! Each year the A
merican
Radio Relay League (ARRL) sponsors Field Day as a rCLpicnic, a campou
t,
practice for emergencies, an informal contest and, most of all, FUN!rC
Y The
event takes place during a 27-hour period on the fourth weekend of June.
For 2026 the event takes place from 1800 UTC on Saturday June 27, 2026
through 2100 UTC on Sunday June 28, 2026. Those who set up prior to 1800
UTC on June 27 can operate only 24 hours. The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via
the amateur satellites, held concurrently with the ARRL event.
This year should be as much fun as last year since we have more than 10 transponders and repeaters available. For AMSAT purposes, a transponder on
a satellite would count as two if you could do phone and CW. We count them
by modes, not the satellite names.
Users should check the AMSAT status page at
http://www.amsat.org/status/
and the pages at
https://www.amsat.org/two-way-satellites/ for what is available in the weeks leading up to field day. To reduce the amount of
time to research each satellite, see the current FM satellite table at
https://www.amsat.org/fm-satellite-frequency-summary/ and the current
linear satellite table at
https://www.amsat.org/linear-satellite-frequency-summary/ .
If you are considering ONLY the FM voice satellites, there are ISS and
SO-50. The congestion on FM LEO satellites is always so intense that we
must continue to limit their use to one-QSO-per-FM-satellite. This includes
the International Space Station. You will be allowed one QSO if the ISS is operating Voice.
It was suggested during past field days that a control station be allowed
to coordinate contacts on the FM satellites. There is nothing in the rules
that would prohibit this. This is nothing more than a single station
working multiple QSOrCOs. If a station were to act as a control stati
on and
give QSOrCOs to every other field day station, the control station wo
uld
still only be allowed to turn in one QSO per FM satellite while the other station would be able to submit one QSO.
The format for the message exchange on the ISS or other digital packet satellite is an unproto packet to the other station (3-way exchange
required) with all the same information as normally exchanged for ARRL
Field Day, e.g.:
W6NWG de KK5DO 2A STX
KK5DO de W6NWG QSL 5A SDG
W6NWG de KK5DO QSL
If you have worked the satellites on Field Day in recent years, you may
have noticed a lot of good contacts can be made on some of the
less-populated, low-earth-orbit satellites like AO-7, RS-44, AO-73, FO-29
and JO-97. During Field Day the transponders come alive like 20 meters on a weekend. The good news is that the transponders on these satellites will support multiple simultaneous contacts. The bad news is that you canrC
Ot use
FM, just low duty-cycle modes like SSB and CW.

Satellites Are The New Fire Towers
The Bezos Earth Fund announced a $26 million grant for the nonprofit Earth
Fire Alliance and its satellite-based wildfire detection program, Axiosr
CO
Ben Geman reports.
The money rCo alongside support from Google and others rCo will
help fund the
launch of three FireSat satellites this summer.
The groups say theyrCOll rCLprovide wildfire monitoring at leas
t twice daily
over critical geographies, including a focus on the Amazon Basin rCo
one of
the most fire-vulnerable regions on Earth.rCY
The funding is the largest-ever single philanthropic grant for wildfire detection, the groups say. They add that the program could help protect
homes, communities and biodiversity rCo and cut CO2 emissions from wi
ldfires
by up to 10% annually.

Wildfires are a major driver of deforestation, which worsens climate
change. They accounted for 42% of tree cover loss in 2025, per World
Resources Institute data.
The Earth Fire Alliance says it hopes to have dozens of satellites
operating by the early 2030s that can rCLmonitor every point on Earth
every
20 minutes.rCY

Announcing OrbitDeck
A new open-source desktop application called OrbitDeck brings the classic OSCARLOCATOR into the software age, pairing a faithful recreation of the beloved paper tracking aid with a built-in classroom of orbital-mechanics lessons. Written in Python and released under the MIT license, OrbitDeck
runs on Windows, macOS, and Linux rCo including the Raspberry Pi r
Co and is
tracking-and-analysis software only; radio and rotator control are intentionally left to the excellent dedicated tools already serving that
role.
*OrbitDeck map screen (Image credit: Paul Stoetzer)*
Longtime operators will remember the OSCARLOCATOR: a polar map overlaid
with a rotating ground-track transparency that let you predict a pass with nothing but a pencil and a clock. OrbitDeck rebuilds that experience as an interactive on-screen OSCARLOCATOR. You drag the map to rotate the path-arc overlay across a polar or QTH-centered base map, watching the satelliter
COs
position and your stationrCOs footprint move in real time. A protract
or-style
rim with per-degree tick marks and longitude and azimuth labels frames the disc. You can drive the overlay live, position it by hand to any equator-crossing longitude, drag the marker along the arc to step through
the minutes after the crossing, or seed it directly to your next visible
pass. A compact next-equator-crossings list is built in.
Crucially, OrbitDeck also closes the loop with paper. Any satellite rC
o real
or hypothetical rCo can be exported as a printable PDF OSCARLOCATOR,
ready to
drop onto a clipboard for portable, screen-free operating in the field or
in the classroom.
That classroom focus runs throughout the program. A dedicated Learn section presents orbital mechanics across grouped, interactive tabs rCo Keple
rrCOs
equal-areas law, anomalies and the vis-viva relation, nodal precession and sun-synchronous orbits, slant range and footprint geometry, Doppler tune-through, eclipse and beta-angle sunlight, a link-budget sandbox, and element-set aging rCo each with a live diagram you can manipulate rat
her than
merely read. A printable rCLOrbits 101rCY handout rounds it out
.
The standout teaching tool is the lab satellite. From within the
OSCARLOCATOR simulator, you can invent a hypothetical bird and edit its
orbital elements with sliders and entry boxes rCo altitude (with the
period
updating live), eccentricity, inclination, RAAN, argument of perigee, mean anomaly, and direct apogee and perigee control. The ground track,
footprint, and range circle respond instantly, plain-language explainers describe the effect of every change, and a gallery of presets loads recognizable archetypes from ISS-like LEO to Molniya and geostationary.
Design an orbit to a requirement, compare two designs side by side, then
name and print your creation as an OSCARLOCATOR exactly like a catalog satellite.
OrbitDeck reads modern GP/OMM data, ships its own SGP4 propagator and an offline catalog so it works without a connection, and is free to download.
It is an inviting on-ramp for newcomers and a genuinely useful operating
and teaching aid for veterans.

Changes to AMSAT TLE Distribution for June 19, 2026
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 daily in the first hour of the UTC day. New bulletin
files will be posted immediately after reliable elements become available
for new amateur satellites. More information may be found at
https://www.amsat.org/keplerian-elements-resources/ <
https://www.amsat.org/keplerian-elements-resources/>.
*There are no changes to this weekrCOs TLE distribution.*
General Perturbations Data Support
AMSAT is pleased to announce that modern forms of what are called General Perturbations data are being disseminated via modern formats including
JSON, XML and KVN at
https://newark192.amsat.org/gpdata/current/. The
reason this change is being made is that we are running out of 5-digit
catalog numbers and the TLE format is not viable for satellites launched
after July of this year. See
https://celestrak.org/NORAD/documentation/gp-data-formats.php for details.
These data are presently considered in beta test for the next two months
while hosted on the test server newark192.amsat.org, and we are very open
to community feedback at
webmaster@amsat.org. Testers may experience
outages and errors while we make improvements. We intend to put this into production on our main web server in July as we expect that satellites
launched after this summer will require one of the new formats to
accommodate longer object numbers. AMSAT will continue to publish TLE
bulletins for satellites launched before July 2026 indefinitely.

Dragon Returns Packed with Space Station Science
Scientists await a big splash in the Pacific Ocean as one of the most research-packed Dragon spacecraft to date returns, completing the 34th
SpaceX commercial resupply mission to the International Space Station for
NASA. Biological and materials samples, along with tested hardware, are
heading back to research teams on Earth for further analysis, advancing NASArCOs work to prepare humans for exploration beyond low Earth orbi
t and to
deliver benefits back home.
*NASA astronaut Jessica Meir prepares samples in the Life Sciences Glovebox
to study how weightlessness affects crew blood clotting and immune function
for the Megakaryocyte Flying-One investigation. (Photo Credit: NASA)*
Some samples returning are for NASArCOs Hematopoietic Stem Cell Expan
sion in
Space: Pathfinder Investigation (InSPA-StemCellEX-H2), which seeks to use
the microgravity environment to scale up the production of stems cells. On Earth, lab-produced blood stem cells lose their ability to form different
cell types, like red and white blood cells that are critical to treating patients with certain blood diseases and cancers. In microgravity,
researchers believe this ability will be better preserved while also
growing these stem cells in greater numbers. The returning samples will
undergo further analysis to determine if space-based efforts produce larger quantities of enhanced stem cells suitable for clinical use.
The team behind NASArCOs Streptococcus pneumoniae (Spn) Infection of
Cardiac
Tissue (MVP Cell-09) experiment is awaiting the return of stem cell-derived heart tissues that were intentionally infected with a pneumonia-causing bacterium as part of ongoing microgravity research. Pneumonia increases the risk of heart disease, which is not fully understood. Because bacteria tend
to become more active and virulent in microgravity, this experiment could amplify their effects, making it possible to detect cellular responses that cannot be observed on Earth.
NASArCOs Megakaryocyte Flying-One (MeF1) samples are returning to Ear
th to
help understand how large cells found in bone marrow, known as
megakaryocytes, and the platelets they produce adapt to spaceflight. Megakaryocytes and platelets play important roles in the formation of blood clots and immune responses. The returning samples, including those taken
from astronauts, could show us how the human immune system reacts aboard
the space station and help prepare for future exploration missions.
Semiconductor research samples as part of NASArCOs In-Space Productio
n of
Semimetal-Semiconductor Composite Bulk Crystals in Microgravity (SUBSA-InSPA-SSCug) investigation are returning to Earth for further
analysis. This study manufactured semimetal-semiconductor composite alloy crystals in space, which have applications in many electronics, including sensors and lasers. Researchers believe microgravity could enable the production of significantly greater and higher-quality crystals, supporting
the development of next-generation semiconductor technologies.
Additional experiments being returned include NASArCOs Zero Boil-Off
Tank
Noncondensables (ZBOT-NC) investigation, NASArCOs DNA Nano Therapeuti
cs-3
space-assembled DNA-inspired materials, NASArCOs InSPA-Sachi Nanoligo
mer
investigation, European Space AgencyrCOs (ESArCOs) Green Bone i
nvestigation,
NASArCOs 3D Bone Marrow Analog research, and NASArCOs InSPA-Aux
ilium

There is a lot of traffic on Facebook and 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:
Wakeup to Workday start+.5 hours
Workday start to Workday end hours
Workday end to Sleep> hours
Sleep to wakeupo.5 hours
The crewrCOs usual waking period is 07:30 rCo 19:30 UTC. The mo
st common times
to find a crew member making casual periods are about one hour after waking
up and about an hour before sleeping, when they have personal time. Theyr
COre
usually free most of the weekend, as well.
The APRS packet system is also active (437.825 MHz up & down).
Ham TV is currently transmitting a test signal at 2395.00 MHz. *The color
bar test generator portion of the Ham TV system is experiencing unexpected technical issues. ARISS is working to troubleshoot the issue with NASAr
COs
payloads support team and the ISS crew.*
As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol. *Radios will be powered down
in support of an upcoming spacewalk in late June: Power down: June 29 at
15:15 UTC Power up: July 1 at 10:15 UTC*
Note, all times are approximate. It is recommended that you do your own
orbital prediction or start listening about 10 minutes before the listed
time.
