AMSAT-UK Tests FM Transponder for Jovian-1 Satellite

David Bowman, G0MRF, reports a successful on-air test of the AMSAT-UK U/V
FM transponder has been carried out.

Destined for the 6U Jovian-1 satellite, this mode U/V FM transponder had
its first on-air test on Thursday, July 24, 2025.

A 70cm 20 watts ERP signal was transmitted over a distance of 59 km with a
path loss of -150 dB and received by the FM transponder on a QFH antenna.
The signal was re-transmitted on 145.895 MHz. The first contact was between Mike Willis, G0MJW, and Graham Shirville, G3VZV.

AO-123 FM Transponder to Enter Continuous Service

The FM transponder on AO-123 has been activated on periodic basis since its launch in late 2024. Beginning this weekend, it is expected to enter
continuous service if no issues are observed.

AO-123 (ASTRU-1) is a 12U Cubesat mission designed by Russian and Chinese university students for education and amateur radio. The amateur radio
station provides telecommand uplink and telemetry / digital image downlink.

A new SDR based transceiver was developed for ASRTU-1 to provide
communication and experiment resources to radio amateurs, including a V/U
FM transponder, a UHF telemetry downlink and a 10.5G image downlink.

The uplink is 145.850 MHz with a 67 Hz CTCSS tone and the downlink is
435.400 MHz.

*[ANS thanks the AO-123 team for the above information]* ------------------------------
HamTV Installed On ISS

On July 29th, Jonny Kim installed the repaired HamTV module in the ISS's Columbus module. Originally operational from mid-2015 until its failure in 2018, the repaired module was returned to the ISS earlier this year.

Shortly after installation, reports of successful carrier reception were received from Europe. Carrier transmission is expected to continue for a
few days.

HamTV transmits live MPEG-2 video using a DVB-S signal on 2395 MHz,
primarily for educational contacts.

NOAA-15 and NOAA-19 to be Decommissioned

NOAA has announced the decommissioning <https://www.ospo.noaa.gov/operations/messages.html> of NOAA-15 and
NOAA-19. NOAA-15 will be decommissioned on August 12, 2025 and NOAA-19 will
be decommissioned on August 19, 2025.

These two remaining satellites in the NOAA Polar Operational Environmental Satellites (POES) Constellation are far beyond their primary mission design life. All have incurred subsystem and instrument degradation or failures
and have entered a "twilight phase" where failure modes are increasingly likely. NOAA has completed End of Life (EOL) testing activities for NOAA-15
and NOAA-19 and will commence the decommission process shortly. NOAA-18 had previously been decommissioned on June 6, 2025 at 1740 UTC.

Many amateur satellite enthusiasts have copied the APT weather data from
NOAA's POES satellites over the years. With a strong signal at 137 MHz,
these satellites have served as a gateway to satellite reception. The decommissioning of these satellites represents an end of an era.
*NOAA 19 at 18 Jun 2021 01:14:11 GMT - APT recorded on 137.100 MHz*

GridMasterMap Satellite Top 100 Rovers August 2025 Rankings

The August 2025 rankings for the Top 100 Rovers (Mixed LEO/MEO/GEO) in satellite operations, as determined by @GridMasterMap <https://x.com/GridMasterMap> on Twitter, has been released. The ranking is determined by the number of grids and DXCC entities activated, taking into account only those grids where a minimum number of QSOs logged on the gridmaster.fr website have been validated by a third party. Grid numbers do
not directly reflect the exact number of activations. Satellite operators
are encouraged to upload their LoTW satellite contacts to
https://gridmaster.fr in order to provide more accurate data.

Changes to AMSAT TLE Distribution for August 1, 2025

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/>.

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

ARISS News

Amateurs and others around the world may listen in on contacts between
amateurs operating in schools and allowing students to interact with
astronauts and cosmonauts aboard the International Space Station. The
downlink frequency on which to listen is 145.800 MHz worldwide.
*Scheduled Contacts*

*Sultanov International Aerospace School, Republic of Bashkortostan,
Russia, direct via TBD*

The ISS callsign is presently scheduled to be RS|yISS
The scheduled crewmember is Sergey Ryzhikov
The ARISS mentor is RV3DR

Contact is go for Mon 2025-08-11 07:45 UTC (***)

Many times a school may make a last minute decision to do a Livestream or
run into a last minute glitch requiring a change of the URL but we at ARISS
may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol.

The crossband repeater continues to be active (145.990 MHz up {PL 67} &
437.800 MHz down), 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.

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.

The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html

The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html

AMSAT Ambassador Activities

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

AMSAT Ambassador Clint Bradford, K6LCS, says,

"Think a 75-minute presentation on "working the easy satellites" would be appropriate for your club or event? Let me know by emailing me at
k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!"

Clint has NEVER given the exact same show twice: EACH of the 150+
presentations so far has been customized/tailored to their audiences.
