They were on the H-IIA Launch Vehicle No. 26 (H-IIA F26) which also carried the asteroid explorer “Hayabusa2”.

The two amateur radio spacecraft will have an elliptic orbit around the Sun and travel to a deep space orbit between Venus and Mars. The inclination will be almost zero, which means the spacecraft should stay in the Earth’s equatorial plane. The distance from the Sun will be between 0.7 and 1.3 AU. An Astronomical Unit (AU) is 149,597,871 km.

ARTSAT2:DESPATCH has a 7 watt CW transmitter on 437.325 MHz and is also the first 3D printed sculpture to be carried into deep space.

Shin’en2 has a CW beacon on 437.505 MHz (0.1 watt) and telemetry on 437.385 MHz (0.8 watt) using a mode which Seiji JH6RTO describes as similar to WSJT but not the same.

The Shin’en2 English language Ground Station page mentions WSJT but the equivalent Japanese language page does not.

The Shin’en2 site indicates there is also a F1D digital transponder with an uplink of 145.942 MHz with 435.270 MHz (0.4 watt) downlink.
