At 01:02 GMT on September 2 a cross band FM amateur radio repeater with a downlink on 437.800 MHz was activated on the International Space Statio.

The Amateur Radio on the International Space Station (ARISS) announcement reads:

The ARISS team is pleased to announce that set up and installation of the first element of our next generation radio system was completed and amateur radio operations with it are now underway. This first element, dubbed the InterOperable Radio System (IORS), was installed in the International Space Station Columbus module. The IORS replaces the Ericsson radio system and packet module that were originally certified for spaceflight on July 26, 2000.

Initial operation of the new radio system is in FM cross band repeater mode using an uplink frequency of 145.99 MHz with an access tone of 67 Hz and a downlink frequency of 437.800 MHz. System activation was first observed at 01:02 UTC on September 2. Special operations will continue to be announced.

The IORS was launched from Kennedy Space Center on March 6, 2020 on board the SpaceX CRS-20 resupply mission. It consists of a special, space-modified JVC Kenwood D710GA transceiver, an ARISS developed multi-voltage power supply and interconnecting cables. The design, development, fabrication, testing, and launch of the first IORS was an incredible five-year engineering achievement accomplished by the ARISS hardware volunteer team. It will enable new, exciting capabilities for ham radio operators, students, and the general public. Capabilities include a higher power radio, voice repeater, digital packet radio (APRS) capabilities and a Kenwood VC-H1 slow scan television (SSTV) system.

A second IORS undergoes flight certification and will be launched later for installation in the Russian Service module. This second system enables dual, simultaneous operations, (e.g. voice repeater and APRS packet), providing diverse opportunities for radio amateurs. It also provides on-orbit redundancy to ensure continuous operations in the event of an IORS component failure.

Next-gen development efforts continue. For the IORS, parts are being procured and a total of ten systems are being fabricated to support flight, additional flight spares, ground testing and astronaut training. Follow-on next generation radio system elements include an L-band repeater uplink capability, currently in development, and a flight Raspberry-Pi, dubbed “ARISS-Pi,” that is just beginning the design phase. The ARISS-Pi promises operations autonomy and enhanced SSTV operations.

ARISS is run almost entirely by volunteers, and with the help of generous contributions from ARISS sponsors and individuals. Donations to the ARISS program for next generation hardware developments, operations, education, and administration are welcome -- please go to https://www.ariss.org/donate.html to contribute to these efforts.

ARISS--Celebrating 20 years of continuous amateur radio operations on the ISS!

świetna wiadomość, domyślam się że na początek będzie duże zainteresowanie i z moimi 5W nie podołam :-)

SQ6GTQ musisz bałobtrzdęka naładować

Robcio,łączność przez iss-a to jak łaczność z PFL-em ,lokal

Powiem Ci ,że czasami może być trudno,zależy jaką elewację ma ISS dostępny w europie,może być,że na pionowej antenie będzie nie do zdobycia w danym przelocie a super będzie na hendiku i również odwrotnie,ale....... kto cierpliwie nie czeka ten się nie doczeka Zdobywcy przestworzy do dzieła.

To Ci powiem ze mam teraz duze szanse bo rusztowanie postawili zaraz się podłącze i zaczekam aż będzie leciał od zachodu bo tak stanowi czoło budynku

Bajo nadaje się do takich wyzwań, ostatnio miałem parę qso na so-50, jednak działa poprawnie ten sat. Słyszeliście juz może ten przemiennik na iss ?

Niestety ISS w godzinach mojej aktywności omija Europę dość dużym łukiem ale przyjdzie czas .....

Niestety przeloty teraz są ale nocne i poranne,trzeba poczekać aż będzie w zasięgu dziennym około 1 miesiąc
