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.

Amateur Radio on the International Space Station (ARISS) logoInitial operation of the new radio system is in FM cross band repeater mode using an uplink frequency of 145.990 MHz with an access tone [CTCSS] 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!

EMF 2020 to contact the ISS via ham radio

EMF 2018 AMSAT-UK VillageThe ARISS-UK Team have announced that the Electromagnetic Field 2020 event is to host an ARISS contact during the weekend of July 23-26.

The event will be held at Easton Manor Deer Park, near Ledbury in Herefordshire.

Amateur Radio Mast at EMF 2018The callsign for the contact will be GB4EMF and the ISS will use NA1SS. More details will be available closer to the date.

Imagine a camping festival with a power grid and high-speed internet access; a temporary village of geeks, crafters, and technology enthusiasts that’s lit up by night, and buzzing with activity during the day. Thousands of curious people will descend on the friendly open space to learn, share, and talk about what they love.

Talks and workshops start at midday on Friday and last until the Sunday evening.

The first public sale of tickets for EMF 2020 will be Wednesday, February 19, at 19:00 GMT. For the full list of ticket sales dates, see https://blog.emfcamp.org/2020/02/14/ticket-sales-dates/

Russian cosmonauts are expected to activate Slow Scan Television (SSTV) image transmissions on 145.800 MHz FM from the International Space Station from Saturday, December 28 to Wednesday, January 1.

ARISS will be supporting SSTV transmissions worldwide in memory of cosmonaut Alexei Leonov. Event runs from setup at 1100 GMT on December 28, 2019 until scheduled shutdown at 1820 GMT on January 1, 2020.

Transmissions will be sent on 145.800 MHz FM (5 kHz deviation) in the SSTV mode PD-120. Once received, images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php

ISS SSTV uses a Kenwood TM D710E transceiver which is part of the amateur radio station located in the Russian ISS Service Module.

Please note that SSTV events are dependent on other activities, schedules and crew responsibilities on the ISS and subject to change at any time. You can check for updates regarding planned operation at:
