SSTV Event Scheduled for ARISS on October 3 2023

R4UAB reports that from October 3, 2023 to October 5, 2023 images will be transmitted from the International Space Station via the SSTV protocol as part of the “About Gagarin from Space” experiment. The topic of the program is the first artificial Earth satellite, amateur radio satellites, school satellites.

SSTV images will be transmitted on 145.800 MHz using a Kenwood TM-D710 transceiver. They are expected to use the PD-120 SSTV format.

The scheduled start of transmission is October 03, 2023 at approximately 14:40 UTC. The end of transmission is scheduled at October 05, 2023 at approximately 18:15 UTC. The date and time may change.

The “Russia ISS SSTV” diploma is awarded to radio amateurs (observers) for receiving SSTV (slow-scan television) broadcasts from aboard the International Space Station (ISS) as part of the space experiment (SE) “About Gagarin from Space.” To receive the “Russia ISS SSTV” Diploma, one must receive and decode three images transmitted over a radio channel from on board the ISS using the SSTV protocol only on the days of the SE . Each image must be at least 90% complete and of acceptable quality. Information on earning the certificate is available at https://r4uab.ru/diplom-iss-sstv/.

AMSAT Argentina is also offering a diploma for reception of ISS SSTV images. Learn more at http://amsat.org.ar/?f=9.

ISS Digipeater active 145.825 MHz

As noted by many ISS AX.25 packet digipeater is now active on 145.825 MHz. For example see this SatNOGS decode: https://network.satnogs.org/observations/6325502/

ARISS is pleased to announce that starting yesterday, August 11,
simultaneous operations of the ARISS Voice Repeater and digital APRS
communications on the International Space Station (ISS) is now a
reality. Current ARISS operations include voice repeater
transmissions with the JVC Kenwood D710GA in the Columbus module and
APRS packet operation from an identical radio in the Service Module
(Zvezda). Packet operations are on 145.825 MHz.

The ARISS Russia and USA teams have been working for several weeks to
prepare the Service Module radio for APRS operations. ARISS Russia
team member Sergey Samburov, RV3DR, led the effort, working with
Russian mission controllers and the on-board ISS cosmonauts to
configure the Service Module radio for APRS ops. On August 11, final
checkouts were completed and the APRS packet mode was switched on for
amateur radio use.

ARISS-International Chair Frank Bauer, KA3HDO states, “Simultaneous
operation of APRS and the voice repeater on ISS is transformative for
ARISS and represents a key element of our ARISS 2.0 initiative,
providing interactive capabilities 24/7 that inspire, engage and
educate youth and lifelong learners—especially life-long learning in
ham radio operations.” Bauer continues, “Our heartfelt thanks to
Sergey Samburov, RV3DR, for making this crucial ARISS 2.0 initiative
become a reality.”

The Columbus Module radio uses the callsign NA1SS and the new Service
Module radio uses RS0ISS. Aside from the callsigns, the radios are
identical and packet operations are the same as before. You can use
RS0ISS, ARISS, or APRSAT as the packet path. Also, both radios are
expected to be on full time, except during educational contacts, EVAs,
and dockings or undockings.

You can find operational status and expected downtimes of the ISS
radios at https://www.ariss.org/current-status-of-iss-stations.

ISS AX.25 2021-04-05

This is my first successful relay via ISS, heard by DO2ZZ. Lots of stations active over EU and very hard to reach ISS with 10 watts. Seen on ARISS.NET:

And direct by myself, Soundmodem:

UISS map:

Hardware and software used:

  • 2*6 el VHF Yagi
  • IC-705 10 watts
  • UISS with Soundmodem, connected to IC-705 via USB
