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.

radios at https://www.ariss.org/current-status-of-iss-stations.

On Twitter we can read about multiple reports that NA1SS is using the crossband repeater for FM QSOs.

Uplink: 145.990 (PL 67 Hz to be safe)
Downlink: 437.800

I've seen multiple reports that NA1SS is using the crossband repeater freqs to make ground contacts BUT the repeater itself is OFF, so you will only hear NA1SS. Crossband simplex/split.

Uplink: 145.990 (PL 67 Hz to be safe)
Downlink: 437.800
