ARLS004 Three CubeSats with Amateur Radio Payloads Deployed from ISS

The Japan Aerospace Exploration Agency (JAXA) has announced that
three CubeSats carrying Amateur Radio payloads, including one with a
V/U linear transponder, were deployed from the International Space
Station (ISS) on May 11 at around 1030 UTC.

Irazu (Costa Rica) and 1KUNS-PF (Kenya) carry beacon/telemetry in
the 70-centimeter Amateur Radio band, while UBAKUSAT (Turkey)
carries an Amateur Radio linear transponder for SSB and CW, in
addition to CW and telemetry beacons. Irazu is a 1U CubeSat
developed by students at the Costa Rica Institute of Technology,
with a telemetry beacon at 436.500 MHz. 1KUNS-PF is a 3U CubeSat
developed by students at the University of Nairobi, with a telemetry
beacon (9.6 kbps) at 437.300 MHz.

UBAKUSAT, a 3U CubeSat developed by students at the Istanbul
Technical University, has a CW beacon at 437.225 MHz, and a
telemetry beacon at 437.325 MHz. The linear transponder downlink is
435.200 - 435.250 MHz; the uplink is 145.940 - 145.990 MHz.
