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.
